Purpose and General Notes The purpose of the Approved Materials List is to streamline the materials submittal and review process during construction. Contractors are strongly encouraged to use materials from the Approved Materials List as these will be expedited and do not require a full technical submittal for review by the District prior to material approval, except for pipe submittals. All pipe materials shall be submitted for review and approval. However, Contractors must submit and identify that materials to be used comply with the approved list and/or current Specifications. Use of “or equal” materials will require a formal and complete submittal subject to review by the Materials Approval Committee (MAC) prior to approval. Any schedule delays as a result of a submittal or use of “or equal” materials will be the sole responsibility of the Contractor. In the event of a conflict between approved/contract drawings and the Approved Materials List, the approved/contract drawings shall take precedence. All materials used for potable water systems must meet California Health and Safety Code 116875 (previously AB1953). All materials that come into contact with potable water must be NSF certified or approved (http://www.nsf.org/). All potable water material submittals must include evidence of NSF certification. Please contact staff if any Model numbers listed are out of date or no longer available. Vendors and Manufacturers wishing to add materials or products to the Approved Materials List shall follow the Vendor Submittal Requirements (http://www.emwd.org/home/showdocument?id=2980) to make a formal submittal to the MAC. Please contact staff for more information.

Mitigation Monitoring and Reporting Program Temecula Valley Recycled Water Pipeline and Appurtenances


K.S. Dunbar & Associates, Inc. March 2015 1 Environmental Engineering

The California Environmental Quality Act (CEQA) requires that when a public agency completes an environmental document which includes measures to mitigate or avoid significant environmental effects, the public agency must adopt a reporting or monitoring program. This requirement ensures that environmental impacts found to be significant will be mitigated. The reporting or monitoring program must be designed to ensure compliance during project implementation (Public Resources Code Section 21081.6).

In compliance with Public Resources Code Section 21081.6, the following MITIGATION MONITORING AND REPORTING CHECKLIST has been prepared for the Temecula Valley Recycled Water Pipeline and Appurtenances Projectg. This Mitigation Monitoring and Reporting Checklist is intended to provide verification that all applicable Conditions of Approval relative to significant environmental impacts are monitored and reported. Monitoring will include: 1) verification that each mitigation measure has been implemented, 2) recordation of the actions taken to implement each mitigation, and 3) retention of records in the Temecula Valley Recycled Water Pipeline and Appurtenances project file.

This Mitigation Monitoring and Reporting Program delineates responsibilities for monitoring the Project, but also allows Eastern Municipal Water District (EMWD) flexibility and discretion in determining how best to monitor implementation. Monitoring procedures will vary according to the type of mitigation measure. Adequate monitoring consists of demonstrating that monitoring procedures took place and that mitigation measures were implemented.

Reporting consists of establishing a record that a mitigation measure is being implemented and generally involves the following steps:

EMWD distributes reporting forms to the appropriate persons for verification of compliance.

Departments/agencies with reporting responsibilities will review the Environmental Impact Report or Initial Study and Mitigated Negative Declaration, which provides general background information on the reasons for including specified mitigation measures.

Problems or exceptions to compliance will be addressed to EMWD as appropriate.

Periodic meetings may be held during project implementation to report on compliance of mitigation measures.

Responsible parties provide EMWD with verification that monitoring has been conducted and ensure, as applicable, that mitigation measures have been implemented. Monitoring compliance may be documented through existing review and approval programs such as field inspection reports and plan review.

EMWD or Applicant prepares a reporting form periodically during the construction phase and an annual reporting summarizing all project mitigation monitoring efforts.

Mitigation Monitoring and Reporting Program Temecula Valley Recycled Water Pipeline and Appurtenances


K.S. Dunbar & Associates, Inc. March 2015 2 Environmental Engineering

Appropriate mitigation measures will be included in construction documents and/or conditions of

permits/approvals.

Minor changes to the Mitigation Monitoring and Reporting Program, if required, would be made in accordance with CEQA and would be permitted after further review and approval by EMWD. Such changes could include reassignment of monitoring and reporting responsibilities, program redesign to make any appropriate improvements, and/or modification, substitution or deletion of mitigation measures subject to conditions described in CEQA Guidelines Section 15162. No change will be permitted unless the Mitigation Monitoring and Reporting Program continues to satisfy the requirements of Public Resources Code Section 21081.6.

1 INTRODUCTION

This report presents the results of Kleinfelder’s geotechnical study for the proposed Reach 4

Recycled Water Booster Station (RCH4RWBS) Upgrade project located within the existing

Eastern Municipal Water District’s (EMWD) Sun City Regional Water Reclamation Facility

(SCRWRF) located at 29285 Valley Boulevard in Menifee, California as shown in Figure 1, Site

Vicinity Map. The existing RCH4RWBS consists of above and below ground pipelines, three

pressurization pumps, two brine flushing pumps, and various support buildings. The site is

paved with asphalt concrete in the vicinity of the proposed improvements. Figure 2, Boring

Location Map, shows the RCH4RWBS in more detail in relation to nearby features.

Based on our understanding of the project from the Request for Proposal (RFP), our

discussions with Brown and Caldwell, and our site reconnaissance, we understand that the

project is to consist of the repurposing of the existing two brine flushing pumps to increase the

overall capacity of the RCH4RWBS. This will likely include the relocation of the two brine

flushing pumps closer the existing pressurization pumps and the installation of pipeline to

facilitate the discharge to and from the new pumping configuration.

Based on our review of the site topography and our understanding of the project requirements,

we anticipate that excavations will be on the order of 5 to 10 feet below existing grades. We

have estimated that the gross weight of the existing brine pumps are on the order of 5 kips each

for our analysis. We anticipate that any new pavement sections will consist of asphalt concrete

and be subject primarily to maintenance vehicles. We have not been provided traffic indices so

our pavement sections are preliminary and subject to the actual loading conditions.


2 PURPOSE AND SCOPE OF SERVICES

We performed this geotechnical study in order to form conclusions and provide recommendations

for geotechnical related aspects of design and construction. Our scope of work for this geotechnical

evaluation included the following tasks:

2.1 FIELD EXPLORATION

A site reconnaissance was conducted to locate and mark our proposed exploratory boring and

coordinate utility clearance. Per California State Law, the Underground Service Alert (USA),

also known as DigAlert, was notified of the proposed boring at least 48 hours prior to

excavating. This allowed participating utility owners to mark out known utility locations adjacent

to the proposed boring location.

The field exploration program consisted of advancing one soil boring using a truck-mounted drill

rig. The location of the boring is shown on Figure 2, Boring Location Map. The boring was

drilled to a depth of approximately 51½ feet below ground surface (bgs). A Kleinfelder

representative was on-site during the field exploration and maintained a log of the soil profile,

depth to groundwater, and collected and labeled soil samples for geotechnical laboratory

testing. The log of the boring and further explanation of the field exploration program are

presented in Appendix A of this report.

Additionally, Appendix C presents the logs of borings for previous investigations in the

immediate vicinity of the project site that we have performed for EMWD. These previous

investigations include the EMWD Solar Phase II project and the EMWD Perris II Desalter

Facility. We have utilized this data to compliment the data from our current investigation.

2.2 LABORATORY TESTING

Following our field exploration, samples were transported to our geotechnical laboratory in

Ontario, California. The soil samples were reviewed and field classifications were confirmed by

the project engineer and representative samples were selected for laboratory testing. The

following tests were performed on the samples collected to evaluate engineering properties:

Moisture content and dry unit weight testing performed in general accordance with

ASTM 2216 and D2937, respectively, on select samples.


Plasticity Index tests in general accordance with ASTM D4318, to evaluate the plasticity

characteristics of site soils.

Compressibility testing using consolidation testing equipment in general accordance with

ASTM D2435/2435M.

Expansion Index Testing in general accordance with ASTM D4829.

R-Value testing for preliminary pavement design, in general accordance with ASTM

D2844.

Corrosion testing to evaluate the soluble sulfates, pH of the soil, chlorides, and minimum

resistivity of native soils.

The results of our laboratory testing and further explanation of testing methods and procedures

can be found in Appendix B of this report. Laboratory testing from our previous investigations

for EMWD in the vicinity of the site can be found in Appendix C. Note that Appendix C contains

excerpts from our original reports which contains both data that is related and unrelated to the

project site. This occurs because data for certain laboratory testing (such as Moisture Content

and Unit Weights) occur on the same page as data which may not be relevant to the site.

2.3 ENGINEERING ANALYSIS AND REPORT PREPARATION

Information obtained from our field exploration and laboratory testing programs were analyzed

in conjunction with our assumed structural loads to develop geotechnical recommendations for

the design and construction of the proposed project. In addition, Kleinfelder reviewed our

previous investigations for EMWD and utilized data that was in the vicinity of the site (Kleinfelder

2010, 2014, 2015). Pertinent data from our previous reports is presented in Appendix C and

discussed in Section 3.2 of this report. This report summarizes the work performed, data

acquired, and our findings, conclusions, and geotechnical recommendations for the design and

construction. This report includes:

A Site Vicinity Map (Figure 1) showing the approximate site location and a Boring

Location Map (Figure 2) showing the approximate location of our exploratory boring.

A discussion of the surface and subsurface conditions encountered at the locations of

the borings (recent and previous borings) and the depth of groundwater.


A discussion of local site geology and seismicity, including seismic design parameters

and seismic site class parameters in accordance with the

2013 California Building Code (CBC).

Engineering conclusions and recommendations for design and construction for:

O Site grading and placement of fill, including anticipated earthwork and site

preparation; wet and dry weather construction considerations; excavation and

trenching; and fill placement and compaction.

O Shallow foundation design, allowable bearing pressures, geotechnical backfill

requirements, anticipated static settlement, minimum embedment depths, and the

friction coefficient.

O Magnitudes of potential liquefaction and seismic settlement.

O Preliminary flexible pavement design

O Results of soil corrosivity characteristics testing and discussion of potential impacts

to concrete and buried metals.


3 SITE CONDITIONS

3.1 TOPOGRAPHY AND DRAINAGE

The project site is located within the existing EMWD SCRWRF. Topographically, the site is

characterized as relatively flat with a mean elevation of approximately 1,420 feet above Mean

Sea Level (MSL) (estimated using publically available online computer software). The site is

adjacent to a nearby creek located just south of the site. The site is developed and consists of

asphalt concrete and several structures that house the equipment for the RCH4RWBS.

There are no active drainages crossing the site. Surface drainage within the study area is via

sheet flow runoff over the existing contour of the land.

3.2 SUBSURFACE SOIL CONDITIONS

Our field exploration consisted of drilling a single boring, B-1, as shown in Figure 2. The boring

was terminated at approximately 51½ feet bgs. A detailed discussion of our exploration program

and the boring log is presented in Appendix A. As discussed previously, Kleinfelder has

performed previous investigations for EMWD in the site’s general vicinity. Pertinent data from

our previous investigations is presented in Appendix C. In general, the subsurface conditions

from our boring were similar to the conditions encountered in our previous explorations. A

general description of the subsurface soil conditions encountered is discussed below.

3.2.1 Fill

Artificial fill was encountered in our boring to a depth of approximately 5 feet bgs. The artificial

fill consists of fine-grained sandy lean clay. The moisture content of a sample of the artificial fill

was 13.2 percent. In our previous explorations, artificial fill thicknesses varied from 2 to 7 feet

and generally consisted of fine-grained sandy lean clays, sandy silts, or silty sands.

3.2.2 Alluvium

Underlying the artificial fill is an alluvial deposit that extends to at least 51½ feet bgs. The

alluvium consists of interbedded layers of fine-grained clays and silts, with some sands and

clayey sands at greater depths. The moisture content of the alluvium samples tested ranged

from 13.7 to 15.5 percent in the upper 20 feet. The dry unit weight of the alluvial samples tested

ranged from 111.4 to 118.0 pounds per cubic foot (pcf). In general, the density and consistency


of the soils increased with depth. Our previous explorations in the vicinity of the site ranged

from 16 ½ to 51 ½ feet bgs and generally encountered similar soils within the alluvium.

3.3 GROUNDWATER

Groundwater was initially encountered in our boring at approximately 35 feet bgs. Water was

measured at a depth of approximately 37 feet bgs at the completion of drilling. In our previous

investigations, we encountered groundwater between 22 to 46 feet bgs (Kleinfelder, 2010, 2014,

2015).

Based on available well data from the Western Municipal Water District Cooperative Well

Measuring Program (WMWD, 2014) regional groundwater is estimated at depths of

approximately 23 to 35 feet bgs measured in existing wells within the EMWD SCRWRF. The

depth to groundwater encountered in Boring B-1, as well as our borings from previous

investigations are consistent with the regional depth to groundwater based on well data. It is

possible that local variations in groundwater levels may occur due to seasonal changes, run-off,

precipitation, irrigation and / or construction activities.

3.4 REGIONAL AND LOCAL GEOLOGY

California is divided into eleven natural geomorphic provinces that are recognized based on

geology, landscape or landform, topographic relief, and climate. Based on the geomorphic

provinces defined by the California Geological Survey (CGS), the project study area is situated

near the northwestern end of the landward portion of the Peninsular Ranges Geomorphic

Province of California. The Peninsular Ranges Province is a distinct geomorphic region

characterized as a complex series of northwest-southeast oriented mountain ranges and valleys

generally sub-parallel to faults comprising the San Andreas rift zone. In the vicinity of the

project site, the Peninsular Ranges Province is further described by sub-units, which include the

Perris Block, the San Jacinto Mountains, and the Santa Ana Mountains. The project site is

located within the eastern portion of the Perris Block, south of the San Jacinto Mountains and

the San Jacinto fault zone. The Perris Block is characterized as a broad area of intermixed

valleys and low mountain ranges situated between the Elsinore and San Jacinto fault zones.

Bedrock of the Perris Block is comprised principally of Cretaceous-age igneous rocks and older

metasedimentary rocks.


The site is located within the Menifee Valley which is a broad relatively flat-floored alluvial valley

surrounded by granitic and metasedimentary bedrock hills. This alluvial valley is drained by

Menifee Creek which drains southwest to the Railroad Canyon Reservoir. Lithologically, the

project site is underlain primarily by Quaternary-age alluvial deposits (Morton and Miller, 2006).

The alluvial soils consist of primarily of fine-grained mixtures of clays and sandy clays with

minor interbedded silty sand and clayey sand. The alluvial deposits were encountered in all

borings (recent investigation and previous investigations) drilled on the site.

The project site is located in the highly seismic southern California region within the influence of

several fault systems that are considered to be active or potentially active. An active fault is

defined by the State of California as a "sufficiently active and well defined fault" that has

exhibited surface displacement within the Holocene time (about the last 11,000 years). A

potentially active fault is defined by the State as "a fault with a history of movement within

Pleistocene time (between 11,000 and 1.6 million years ago)." These active and potentially

active faults are capable of producing potentially damaging seismic shaking at the site. It is

anticipated that the project site will periodically experience ground acceleration as the result of

small to large magnitude earthquakes.

Faults identified by the State as being either active or potentially active are not known to be

present on site. The site is not located within a State of California designated Earthquake Fault

Zone (EFZ) for ground rupture (Bryant and Hart, 2007). Nor is the site located within a state

designated seismic hazard zone for liquefaction or seismically induced slope instability. The

nearest active fault zones are the Elsinore fault (Temecula Segment) approximately 6.0 miles

southwest and the San Jacinto fault approximately 13.5 miles northeast of the site. A major

seismic event on these faults have the potential to cause strong ground shaking at the site.

The site may also be subjected to ground motion from a seismic event occurring on any of the

other numerous active faults in the region. The site is located on the USGS Romoland,

California 7.5 minute Quadrangle Map, at approximate Latitude 33.694688°N and

Longitude -117.211078°W located at the approximate center of the site.


4 CONCLUSIONS

Based on the results of our observations, the field exploration, laboratory test results,

geotechnical analyses conducted for this evaluation, and our experience at nearby sites, the site

may be developed as proposed provided that the recommendations of this report are

incorporated into the design and construction of this project.

4.1 FOUNDATIONS

The subsurface conditions are appropriate for shallow foundations and equipment pads in

support of the RCH4RWBS Upgrade project. The recommendations provided in the next section

are based on the results of the field exploration, laboratory testing and our engineering analysis.

4.2 SEISMICITY AND LIQUEFACTION

Based on the properties of the soils encountered in our boring and our knowledge of geologic

conditions in the area of the site, a site class of ‘D’ is considered appropriate as determined

from Table 20.3-1 of ASCE 7-10 in accordance with the 2013 California Building Code (CBC).

The characteristics of the soils and the local groundwater level indicate that the site soils have a

low to moderate potential for liquefaction settlement during a design level earthquake. The

estimated liquefaction settlement is discussed in Section 5 of this report.

4.3 CORROSIVITY

Chemical tests were performed on selected samples of the near-surface soils to estimate pH,

resistivity and sulfate and chloride contents. The samples were tested for pH and minimum

resistivity, soluble chlorides, and soluble sulfates. The corrosion testing results indicate that the

near surface soils at the site have an “extremely corrosive” potential to buried ferrous metals

and a negligible corrosion potential to concrete in contact with the site soils. A further

discussion on the results of our corrosivity testing is in Section 5 of this report.

4.4 EXCAVATABILITY

Based on drilling observations and the materials encountered, we anticipate that excavations at

this site may be performed with conventional medium- to heavy-duty earth excavating

equipment.


4.5 ON-SITE SOIL AS FILL MATERIAL

Based on the results of laboratory testing, we anticipate that the on-site alluvial soils will be

reusable as engineered fill once debris, vegetation, and large particles have been segregated,

providing that they can be adequately moisture conditioned. Additional details for placement

and compaction of fill are presented in Section 5 of this report.

4.6 EXPANSION POTENTIAL

Results of our laboratory testing indicate that the site soils have a very low expansion potential.

Expansion characteristics may vary based on soils encountered during grading and should be

evaluated during grading. Based on our laboratory testing results, expansive soils are unlikely to

have a significant impact during construction.


5 RECOMMENDATIONS

5.1 EARTHWORK

5.1.1 General

Site preparation and earthwork operations should be performed in accordance with applicable

codes, safety regulations and other local, state or federal guidelines. References to maximum

dry density values are referencing ASTM D1557 Modified Proctor.

5.1.2 Site Preparation and Overexcavation

Areas where foundations, large equipment, and roadways are proposed and fill depths exceed

about 6 inches should be stripped of vegetation and deleterious, organic material as well as

material greater than 3 inches in maximum dimension and disposed off-site or in landscape

areas. Stripping operations should be observed by the geotechnical engineer, and should

include removing materials that, in the judgment of the geotechnical engineer, are not suitable

for the anticipated loading conditions. Because the upper 5 feet of the site contain artificial fill

consisting of fine-grained compressible clays, we recommend that locations for structural areas

such as foundations, equipment pads, and other structural features be overexcavated to a

minimum of 5 feet below existing grades or 2 feet below the bottoms of spread footings,

whichever is greater. For nonstructural areas such as roadways, truck aprons, sidewalks, or

other flatwork areas, the onsite soils should be overexcavated to a depth to a minimum of 2 feet

below existing grade, or 2 feet below the finished subgrade, whichever is deeper.

Overexcavation involves the removal and replacement of on-site native materials as engineered

fill to provide uniform support for shallow foundations or subgrade preparation. Areas to receive

engineered fill should be prepared as discussed in Section 5.1.4 of this report. Topsoil should

be removed prior to placement of engineered fill. Topsoil consists of loose or soft upper

material that contains organic matter such as roots. Topsoil removed that is not suitable for

engineered fill may be used in non-structural or landscape areas.

5.1.3 Subgrade Preparation

The suitability of the exposed subgrade should be evaluated by the geotechnical engineer after

site preparation by observing proof rolling of the subgrade. The subgrade should be scarified to

a depth of 6 to 8 inches; moisture conditioned to 0 to 5 percent above optimum moisture

content; and compacted. After compaction, proof-rolling should be conducted using a fully-

loaded dump truck or similar heavy rubber-tire construction equipment.


Soft areas identified during proof rolling should be over-excavated as recommended by the

geotechnical engineer during observation. Over excavations should be backfilled with structural

fill as recommended in the structural fill section of this report.

5.1.4 Engineered Fill

Structural Fill

We anticipate that most of the on-site soils can be used as site engineered fill and trench backfill

provided the material is free of particles larger than 3 inches in diameter, organic matter, and

other deleterious materials. Engineered fill should contain less than 3 percent organic content

and maximum material size should be less than 3 inches in maximum dimension. Topsoil

without vegetation may be used in landscape areas, exported, or placed in a controlled manner

and blended with the onsite soils provided that the resulting engineered fill contains less than

3 percent organic content.

Fill Placement and Compaction

Fill soils should be compacted at moisture contents that are 0 to 5 percent above optimum

moisture content for fine-grained soils and within 2 percent (plus or minus) optimum moisture

content for coarse-grained soils. Fill and backfill material should be placed in uniform,

horizontal lifts, and be compacted to at least 90 percent of the maximum dry density (ASTM D

1557), using appropriate equipment. In areas where pavement sections will be constructed, the

upper 12 inches beneath the pavement section should be compacted to at least 95 percent the

maximum dry density and moisture conditioned as indicated above. Lift thickness of loose soil

should not exceed 8 inches. Fill placement and compaction should adhere to the latest EMWD

Standard Plans and Specifications (EMWD, 2016).

Select Imported Granular Fill

Select imported granular material or the on-site granular materials meeting the requirements in

this section may be used as engineered fill below equipment pads and foundations. Import fill

should consist of granular material that is fairly well graded between coarse and fine sizes. It

should contain no clay balls, roots, organic matter or other deleterious materials, and have a

maximum particle size of 3 inches, with less than 30 -percent passing the U.S. No. 200 Sieve.

Imported fill materials to be used for engineered fill should be sampled and tested for approval


by the geotechnical engineer prior to being transported to the site. Please provide a minimum

of 2 business days to allow for qualification testing.

Imported Aggregate Base Rock/Crushed Rock

Import aggregate base rock or crushed rock may be used throughout the facility to provide

nonstructural, non-engineered pathways and cover. Aggregate base rock should consist of

imported clean, durable, crushed angular rock. Such rock should be well-graded, contain no

roots, organic matter and other deleterious materials, have a maximum particle size of 1-1/2

inch, and less than 5 percent passing the U.S. No. 200 Sieve. Import aggregate base rock/

crushed rock should be sampled and tested for approval by the geotechnical engineer prior to

being placed. Please provide a minimum of 2 business days to allow for qualification testing.

5.1.5 Temporary Excavations

Excavations must comply with applicable local, state, and federal safety regulations including

the current OSHA Excavation and Trench Safety Standards. Construction site safety is the

responsibility of the contractor, who shall also be solely responsible for the means, methods,

and sequencing of construction operations. We are providing the information below as a

service to our client. Under no circumstances should the information provided be interpreted to

mean that Kleinfelder is assuming responsibility for construction site safety or the Contractor's

activities; such responsibility is not being implied and should not be inferred.

Near-surface soils that we encountered during our field investigation consisted of soft to firm

clays. These materials may be considered Type B soils with regard to the

OSHA regulations. OSHA requires a maximum slope inclination of 1:1 for Type B soils for

excavations up to 20 feet deep. The Contractor’s OSHA-qualified “competent person” must

make the actual determination of soil type and allowable slope inclinations in the field whenever

personnel exposure is anticipated. Where space or other restrictions do not allow a sloped

temporary excavation, shoring or shield system may be required. Shoring recommendations are

presented in the following section.

Temporary, shallow excavations with vertical side slopes less than 4 feet high should generally

be stable, although sloughing may be encountered. Vertical excavations greater than 4 feet

high should not be attempted without appropriate shoring to prevent local instability. All trench

excavations should be braced and shored in accordance with good construction practice and all

applicable safety ordinances and codes. The contractor should be responsible for the structural


design and safety of the temporary shoring system, and we recommend that this design be

submitted to Kleinfelder for review to check that our recommendations have been incorporated.

Stockpiled (excavated) materials should be placed no closer to the edge of an excavation than a

distance equal to the depth of the excavation. All trench excavations should be made in

accordance with OSHA requirements.

5.1.6 Slopes

Based on our current understanding of the proposed project and our review of the site plan, we

do not anticipate the construction of new fill slopes or cut slopes. We have not evaluated slopes

for the subject project.

5.1.7 Pipe Bedding and Trench Backfill

Pipe bedding and pipe zone material should consist of sand or similar granular material having

a minimum sand equivalent value of 30. The sand should be placed in a zone that extends a

minimum of 12 inches below and 12 inches above the pipe for the full trench width. The pipe

zone material (area 12 inches above and below the pipe) should be compacted to a minimum of

90 percent of the maximum dry density or to the satisfaction of the geotechnical engineer's

representative observing the compaction of the bedding material. Bedding material should

consist of sand, gravel, crushed aggregate, or native free-draining granular material with a

maximum particle size of ¾ inch. Bedding materials should also conform to the pipe

manufacturer's specifications, if available. Trench backfill above bedding and pipe zone

materials may consist of approved, on-site or import soils placed in lifts no greater than 6 inches

loose thickness and compacted to 90 percent of the maximum dry density based on ASTM Test

Method D1557. Jetting or ponding of backfill is not recommended. Pipe bedding and trench

backfill should adhere to the latest EMWD Standard Provisions and Specifications (EMWD,

2016). The on-site soils are not anticipated to meet the requirements for pipe bedding and pipe

zone material due to the clayey fine-grained nature of the onsite soils. Therefore, import soils

will likely be required for pipe bedding and pipe zone material. The onsite soils are anticipated

to be used for trench backfill above the pipe zone (area 12 inches above the pipe) to the

finished subgrade or pavement section elevation.


5.1.8 Stockpiling Excess Materials

All stockpiles of excess soil materials should be kept away from the top of the excavations a

minimum distance equal to the depth of the excavation. We recommend that stockpiles be

constructed with a slope ratio of at least 2:1 (horizontal to vertical) and compacted to at least

85 percent relative compaction. The height of stockpiles should not exceed 10 feet.

Compaction requirements and slope ratios are provided only for temporary stockpiling

considerations, such as erosion control and temporary influences on excavations. We have not

considered any long-term or structural support usage of stockpiles.

5.2 SEISMIC DESIGN CONSIDERATIONS

The following seismic design parameters are based on the 2013 California Building Code (CBC)

and are based on a Site Class of “D” as determined by our field exploration and analysis. We

determined these parameters using the Seismic Hazard Curves, Response Parameters and

Design Parameters application from the USGS website for the approximate center of the site.

5.2.1 Liquefaction and Seismic Settlement

The term liquefaction describes a phenomenon in which saturated, cohesionless soils

temporarily lose shear strength (liquefy) due to increased pore water pressures induced by

strong, cyclic ground motions during an earthquake. Structures founded on or above potentially

liquefiable soils may experience bearing capacity failures due to the temporary loss of


foundation support, vertical settlements (both total and differential), and undergo lateral

spreading. The factors known to influence liquefaction potential include soil type, relative

density, grain size, confining pressure, depth to groundwater, and the intensity and duration of

the seismic ground shaking. The cohesionless soils most susceptible to liquefaction are loose,

saturated sands and some silt.

The site is located as having a low to moderate liquefaction potential based on Riverside County

Liquefaction Hazard Maps (Riverside County, 2016). Based on available data and our borings,

groundwater fluctuates between 22 and 35 feet below ground surface within the area. The

highest encountered groundwater within the area was 22 feet below ground surface during a

previous investigation (Kleinfelder, 2011).

Liquefaction analysis was performed in accordance with the guidelines described in Special

Publication 117A (CGS, 2008), Guidelines for Evaluating and Mitigating Seismic Hazards in

California, by the California Department of Conservation, California Geological Survey. A peak

ground acceleration (PGA) of 0.52 in accordance with the 2013 California Building Code and an

earthquake magnitude of 7.6 was used as the design-level seismic event for our liquefaction

analyses. The earthquake magnitude was estimated using by performing a deaggradation from

the USGS website using a 2% exceedance probability in 50 years. The historic high

groundwater was conservatively taken as 16 feet bgs to account for fluctuation in our highest

encountered groundwater table of 22 feet bgs.

Based on the soil type, depth to groundwater, and results of our analysis, we estimated the

potential liquefaction settlement based on our boring, B-1. The liquefaction settlement is

estimated to be less than 1½ inches. The estimated differential settlement due to liquefaction is

approximately half of the total liquefaction settlement, or approximately ¾ inches.

5.2.2 Dry Seismic Settlement

An evaluation of the dry seismic settlement was performed using a PGA of 0.52 and earthquake

magnitude of 7.6. The settlement of the onsite soils during an earthquake during dry conditions

is estimated to be less than ½ inch total and ¼ inch differential.


5.3 FOUNDATIONS

5.3.1 Spread Footings

Spread footings should be supported on a minimum of 2 feet of engineered fill constructed in

accordance with the recommendations presented in section 5.1.4 above. The engineered fill

should extend at least 5 feet horizontally beyond the edges of foundations, or a distance equal

to the depth of overexcavation, whichever is greater. Footings at least 2 feet below finished

grade and supported on a minimum of 2 feet of engineered fill may be designed for a maximum

allowable bearing pressure of 2,500 psf. The allowable bearing pressure provided above is a

net value; therefore, the weight of the foundation (which extends below grade) may be

neglected when computing dead loads. The allowable bearing pressure applies to dead plus

live loads. This value may be increased by one-third for short-term transient loading due to

wind or seismic forces. Tension loads should be resisted by the mass of the footing alone.

Isolated footing pads should be at least 2 feet in width.

Lateral loads on footings can be resisted by passive earth pressure on the sides of footings and

by friction on the bearing surface. We recommend that passive earth pressures be calculated

using an allowable equivalent unit weight of 250 pcf. We recommend using an allowable friction

coefficient of 0.30. These values represent allowable values and have already been reduced by

an appropriate factor of safety based on our engineering judgement and experience. The

passive earth pressure value is based on the assumptions that the adjacent grade is level and

that static groundwater remains below the base of the footing throughout the year. A one-third

increase in the passive resistance may be used for resistance to transient loads such as wind

and seismic. The top 1 foot of soil should be neglected when calculating passive lateral earth

pressures.

We estimate total vertical movement for footings due to settlement under static foundation loads

will be about one inch or less. Differential settlement is anticipated to be approximately ½ to ¾

of the total movement.

To avoid surcharging existing utilities and walls below grade, foundations should be deepened

below a 1:1 (H:V) plane projected from the bottom of the utility or wall. Alternatively, the utilities

or wall could be evaluated for potential surcharge pressures due to the foundation loads.


5.4 TEMPORARY SHORING

5.4.1 General

Temporary shoring will likely be required in excavations during construction. The following

sections present our recommendations for the design of temporary shoring. The actual shoring

design should be provided by a civil engineer registered in the State of California and

experienced in the design and construction of shoring under similar conditions. Kleinfelder

should review the shoring plans for conformance with the design intent and geotechnical

recommendations.

5.4.2 Lateral Earth Pressures

For the design of cantilevered shoring, an equivalent active fluid pressure of 50 pounds per

cubic foot (pcf) may be used for level backfill. While not anticipated to impact the project, the

shoring should be designed for hydrostatic water pressure if groundwater is encountered.

However, groundwater was encountered at approximately 35 feet bgs, and is unlikely to impact

the project. Lateral surcharge loads (e.g., traffic, structures, etc.) located within a 1½:1 (H:V)

plane drawn upward from the base of the excavation should be added to the lateral earth

pressures. The lateral contribution of a uniform surcharge load located immediately behind the

wall may be calculated by multiplying the surcharge by 0.4. Lateral load contributions of

surcharges located at a distance behind the shored wall may be provided once the load

configurations and layouts are known. As a minimum, a 2-foot equivalent soil surcharge (240

psf) is recommended to account for traffic and nominal construction loads.

5.5 RETAINING WALLS

Based on our review of the site plan provided to us and our understanding of the project, we do

not anticipate any retaining walls for the subject project.

5.6 EQUIPMENT PADS

Equipment pads underlain by engineered fill may be designed based on a net allowable bearing

pressure of 1,500 psf and a modulus of subgrade reaction of 150 psi per inch of deflection. To

provide a support, the equipment pads should be underlain by a minimum of 12 inches of low-

to non-expansive fill compacted to a minimum of 90 percent maximum dry density (ASTM D

1557). We recommend providing the pads with turned-down edges to a depth of 18 inches


bgs, and designing the pad to have adequate structural reinforcement to span differential

movement.

Prior to placing reinforcing steel or concrete, slab excavations should be cleaned of debris,

loose or soft soil, and water. We recommend that the slab be reinforced and provided with

control joints complying with American Concrete Institute (ACI) recommendations. The ground

surface around the slab should be sloped to drain away from the slab with a grade of at least 5

percent.

We recommend that a representative from Kleinfelder observe equipment pad preparation in

order to evaluate bearing materials and to confirm that the recommendations made in this report

are implemented during construction.

5.7 EXPANSIVE SOILS

Expansive soils are characterized by their ability to undergo significant volume change (shrink

or swell) due to variations in moisture content. Changes in soil moisture content can result from

rainfall, landscape irrigation, utility leakage, roof drainage, perched groundwater, drought, or

other factors, and may cause unacceptable settlement or heave of structures, concrete slabs

supported-on-grade, or pavements supported over these materials. Depending on the extent

and location below finished subgrade, expansive soils can have a detrimental effect on

structures. Expansion index testing was performed on a near surface sample of the onsite

materials and in our previous investigations. The results of the testing indicate a very low

expansion potential.

5.8 PRELIMINARY PAVEMENT DESIGN

We performed two resistance value (R-value) tests on representative bulk samples of the

anticipated pavement subgrade materials encountered at the site. Laboratory testing indicated

an R-Value of 14 for the near surface soils.

5.8.1 Asphalt Concrete Pavement Sections

Pavement sections presented in Table 2 below are based on a design R-value of 14 and current

Caltrans design procedures. Traffic indices of 5.0 and 7.0 were assumed for the design of

automobile parking areas, automobile driveways/access ways, and heavy truck

driveways/access ways, respectively. Traffic indices assumed above should be reviewed by the


project Owner, Architect, and/or Civil Engineer to evaluate their suitability for this project.

Changes in the traffic indices will affect the corresponding pavement section.

Asphalt Concrete

Aggregate Base

Indices (inches) (inches)

Parking Areas, Light Traffic Areas 5.0 3.0 10.0

Moderate Traffic Areas, including some truck traffic

Pavement sections provided above are contingent on the following recommendations being

implemented during construction.

All pavement subgrades should be prepared as recommended in the SITE

PREPARATION and ENGINEERED FILL sections of this report.

The upper 12 inches of engineered fill beneath pavement sections should be compacted

to 95 percent relative compaction.

Subgrade soils should be in a stable, non-pumping condition at the time aggregate base

materials are placed and compacted.

Aggregate base materials should be compacted to at least 95 percent relative

compaction.

Adequate drainage (both surface and subsurface) should be provided such that the

subgrade soils and aggregate base materials are not allowed to become wet.

Aggregate base materials should meet current Caltrans specifications for Class 2

aggregate base.

Asphalt paving materials and placement methods should meet current Caltrans

specifications for asphalt concrete.

All concrete curbs separating pavement and landscaped areas should extend at least

3 inches into the subgrade and below the bottom of adjacent, aggregate base materials.


5.9 CORROSION TESTING

Chemical tests were performed on a composite sample from approximately 5 to 10 feet below

ground surface to estimate pH, resistivity and sulfate and chloride contents. The samples were

tested for pH and minimum resistivity, soluble chlorides, and soluble sulfates, respectively.

Corrosion Testing was performed by AP Engineering and Testing, Inc. of Pomona, California.

Table 3 below presents the corrosion testing results.

Table 3 Corrosion Testing Results

Boring Depth

(ft) pH Sulfate (ppm)

Chloride (ppm)

Minimum Resistivity (ohm-cm)

B-1 5-10 7.9 551 37 736

These tests are only an indicator of soil corrosivity for the samples tested. Other soils found on

site may be more, less, or of a similar corrosive nature. Imported fill materials should be tested

to confirm that their corrosion potential is not more severe than those noted.

Although Kleinfelder does not practice corrosion engineering, soils with the above resistivity

values are normally considered “extremely corrosive” to buried ferrous metals (Roberge, 2006).

The concentrations of soluble sulfate indicate that the potential of sulfate attack on concrete in

contact with the on-site soils is negligible based on ACI 318 Table 4.2.1 (ACI, 2011).

Accordingly, the American Concrete Institute has no special provisions for cement type or

maximum water-cement ratios for this sulfate exposure.

We recommend that the corrosion test results be reviewed and evaluated by the project

designers considering the proposed improvements and project lifespan requirements.

Kleinfelder does not practice corrosion engineering and the purpose of our corrosion tests is

only to provide a preliminary screening. Additional sampling and testing may be performed after

completion of grading for the proposed site improvements. A qualified corrosion engineer can

be contacted to for detailed evaluation of corrosion potential with respect to construction

materials at this site and review the proposed design.


5.10 EARTHWORK OBSERVATION AND TESTING

We consider geotechnical observation and testing a continuation of this evaluation. As the firm

that provided the geotechnical evaluation for this project, Kleinfelder is the geotechnical

engineer of record, and should be retained to confirm that the recommendations of this report

are properly incorporated in the design of this project, and are properly implemented during

construction. These services provide Kleinfelder the opportunity to observe the actual conditions

encountered during construction and to evaluate the applicability of the recommendations

presented in this report to the site conditions.

APPENDIX A

FIELD EXPLORATION

The subsurface exploration program for the proposed project consisted of drilling and logging

one (1) hollow-stem auger boring. The boring was drilled with a Mobile B-61 truck-mounted drill

rig equipped with 8-inch diameter hollow-stem augers provided by California Pacific Drilling of

Calimesa, California. The drill rig was equipped with an automatic hammer system to drive the

samplers. The location of the boring is shown on Figure 2, Boring Location Map.

The log of the boring is presented as Figures A-3 and A-4, Logs of Borings. An explanation to

the log is presented on Figures A-1 and A-2. The log of the boring describes the earth materials

encountered, samples obtained, and shows field and laboratory tests performed. The log also

shows the boring number, excavation date and the name of the logger and excavation

subcontractor. A Kleinfelder staff engineer logged the boring utilizing the Unified Soil

Classification System. The boundaries between soil types shown on the logs are approximate

because the transition between different soil layers may be gradual. Bulk and drive samples of

representative earth materials were obtained from the boring at maximum intervals of

approximately 5 feet.

A California sampler was used to obtain drive samples of the soil encountered. This sampler

consists of a 3 inch O.D., 2.4 inch I.D. split barrel shaft that is driven a total of 18 inches into the

soil at the bottom of the boring. The soil was retained in six 1-inch brass rings for laboratory

testing. The sampler was driven using a 140-pound hammer falling 30 inches. The total

number of hammer blows required to drive the sampler the final 12 inches is termed the blow

count and is recorded on the Log of the Boring. Where the sample was driven less than

12 inches, the number of blows to drive the sample for each 6-inch segment, or portion thereof,

is shown on the logs. For example, 50/4" indicates 50 blows to drive the sampler 4 inches to

refusal.

Samples were also obtained using a Standard Penetration Sampler (SPT). This sampler

consists of a 2-inch O.D., 1.4-inch I.D. split barrel shaft that is advanced into the soils at the

bottom of the drill hole a total of 18 inches. The sampler was driven using a 140 pounds

hammer falling 30 inches. The total number of hammer blows required to drive the sampler the

final 12 inches is termed the blow count (N-value) and is recorded on the Log of the Boring.

Where the sample was driven less than 12 inches, the number of blows to drive the sample for

each 6-inch segment, or portion thereof, is shown on the logs. The procedures we employed in

the field are generally consistent with those described in ASTM Standard Test Method D-1586.

20172441.001A/RIV16R50421 Page A-2 of 2 March 6, 2017 Copyright 2017 Kleinfelder

Soil samples obtained from the SPT were stored in plastic bags. Bulk samples of the sub-

surface soils were retrieved directly from the soil cuttings and placed in large plastic bags,

generally from the auger cuttings.

The soil boring location shown on Figure 2 is approximate and was located in the field using

hand techniques, such as a measuring tape, wheel tape, and pacing. The boring location was

not surveyed and the latitude, longitude and elevations presented on the log of the boring were

estimated using publically available online computer software.

APPENDIX B

LABORATORY TESTING

Laboratory tests were performed on representative intact and bulk soil samples to estimate

engineering characteristics of the various earth materials encountered. Laboratory testing was

performed by Kleinfelder, with the exception of corrosion testing which was performed by AP

Engineering and Testing, Inc. of Pomona, California. Testing was performed in accordance with

one of the following references:

1. Lambe, T. William, Soil Testing for Engineers, Wiley, New York, 1951.

2. Laboratory Soils Testing, U.S. Army, Office of the Chief of Engineers, Engineering

Manual No. 1110-2-1906, November 30, 1970.

3. ASTM Standards for Soil Testing, latest revisions.

State of California Department of Transportation, Standard Test Methods, latest revisions.

LABORATORY MOISTURE DETERMINATIONS AND UNIT WEIGHTS

In-situ moisture content and unit weight tests were performed on selected samples. The

moisture content and unit weight tests were performed in general accordance with ASTM Test

Method D2216 and D7263, respectively. The results are presented on the Logs of Borings and

are summarized in Table B-1, Moisture Content Determinations and Unit Weights and on the

Logs of Borings.

PLASTICITY INDEX TESTING

Plasticity limit and liquid limit testing was performed on a soil sample to evaluate behavior

conditions at varying water contents. Testing was performed in general accordance with ASTM

Standard Test Method D4318. The test result is presented on the Logs of Borings and as

Figure B-1, Plasticity Testing.

CONSOLIDATION

A consolidation test was performed on a relatively intact sample for evaluating the

compressibility of the native soil in accordance with ASTM Standard Test Method

D2435/2435M. The results of the test are presented as Figure B-2, Consolidation Test.


EXPANSION INDEX

A bulk sample was tested to determine the expansion potential of the near-surface soils. Testing

was performed in general accordance with ASTM Standard Test Method D4829. The below

table from ASTM D4829 shows the expansion potential of soil based on the results of the

expansion index test. The results are presented in Table B-2, Expansion Index Test Results.

Expansion Index (EI) Potential Expansion

0-20 Very Low 21-50 Low 51-90 Medium

91-130 High >130 Very High

R-VALUE TESTING

R-Value testing was performed on a bulk sample of the on-site soils to determine the pavement

characteristics of the soil. The testing was performed in accordance with ASTM D2844. The

test results are presented in Table B-3, R-Value Test Results.

CORROSION TESTS

A series of chemical tests were performed on select near-surface soil samples to evaluate pH,

resistivity, sulfate and chloride contents. Corrosion testing was performed by AP Engineering

and Testing Inc. of Pomona, California. The results of these tests are presented in Table B-4,

Corrosion Test Results.

APPENDIX B

LABORATORY TESTING

Laboratory tests were performed on drive and bulk soil samples to estimate engineering

characteristics of the various earth materials encountered. Testing was performed in

general accordance with procedures outlined in the American Society for Testing and

Materials, or other accepted procedures.

LABORATORY MOISTURE AND DENSITY DETERMINATIONS

Natural moisture content and dry density tests were performed on selected soil

samples. Moisture content was evaluated in general accordance with ASTM Test

Method D 2216; dry unit weight was evaluated using procedures similar to ASTM Test

Method D 2937. The results are presented on the Logs of Borings and are summarized

in Table B-1, Moisture Content and Unit Weight.

APPENDIX DState Revolving Fund

American Iron and Steel Requirements

Rev 06072017 1 | P a g e

State Revolving Fund American Iron and Steel Requirement This project is subject to the Consolidated Appropriations Act of 2014 (Public Law 113-76), which includes an "American Iron and Steel (AIS)" requirement for projects funded by the Clean Water State Revolving Fund (CWSRF) and Drinking Water State Revolving Fund (DWSRF) to use iron and steel products that are produced in the United States for projects for the construction, alteration, maintenance, or repair of a public water system or treatment works. Below is an excerpt from the Environmental Protection Agency (EPA) memorandum implementing the American Iron and Steel (AIS) requirements, which is in the form of questions and answers that address the types of products covered. Compliance requires submission of certification letters by the manufacturer with all AIS shop drawing submittals. Covered Iron and Steel Products What is an iron or steel product? The term ‘‘iron and steel products’’ means the following products made primarily of iron or steel that is permanently incorporated into the public water system or treatment works, which are:

• Lined or unlined pipes and fittings • Manhole covers and other municipal castings (see additional details below) • Hydrants • Tanks • Flanges • Pipe clamps and restraints • Valves • Structural steel (see additional details below) • Reinforced precast concrete • Construction materials (see additional details below)

What does the term ‘primarily iron or steel’ mean? ‘Primarily iron or steel’ places constraints on the list of products above. For one of the listed products to be considered subject to the AIS requirements, it must be made of greater than 50% iron or steel, measured by cost. The cost should be based on the material costs. Can you provide an example of how to perform a cost determination? For example, the iron portion of a fire hydrant would likely be the bonnet, body and shoe, and the cost then would include the pouring and casting to create those components. The other material costs would include non-iron and steel internal workings of the fire hydrant (i.e., stem, coupling, valve, seals, etc). However, the assembly of the internal workings into the hydrant body would not be included in this cost calculation. If one of the listed products is not made primarily of iron or steel, United States (US) provenance is not required. An exception to this definition is reinforced precast concrete, which is addressed in a later question.

Rev 06072017 2 | P a g e

If a product is composed of more than 50% iron or steel, but is not listed in the above list of items, must the item be produced in the US? Alternatively, must the iron or steel in such a product be produced in the US? The answer to both question is no. Only items on the above list must be produced in the US. Additionally, the iron or steel in a non-listed item can be sourced from outside the US. What is the definition of steel? Steel means an alloy that includes at least 50 percent iron, between .02 and 2 percent carbon, and may include other elements. Metallic elements such as chromium, nickel, molybdenum, manganese, and silicon may be added during the melting of steel for the purpose of enhancing properties such as corrosion resistance, hardness, or strength. The definition of steel covers carbon steel, alloy steel, stainless steel, tool steel, and other specialty steels. What does ‘produced in the United States’ mean? Production in the United States of the iron or steel products used in the project requires that all manufacturing processes, including application of coatings, must take place in the United States, with the exception of metallurgical processes involving refinement of steel additives. All manufacturing processes includes processes such as melting, refining, forming, rolling, drawing, finishing, fabricating and coating. Further, if a domestic iron and steel product is taken out of the US for any part of the manufacturing process, it becomes foreign source material. However, raw materials such as iron ore, limestone and iron and steel scrap are not covered by the AIS requirement, and the material(s), if any, being applied as a coating are similarly not covered. Non-iron or steel components of an iron and steel product may come from non-US sources. For example, for products such as valves and hydrants, the individual non-iron and steel components do not have to be of domestic origin. Note: Coating process applied to external surfaces of iron and steel components are not covered. Are the raw materials used in the production of iron or steel required to come from US sources? No. Raw materials, such as iron ore, limestone, scrap iron, and scrap steel, can come from non-US sources. If an above listed item is primarily made of iron or steel, but is only at the construction site temporarily, must such an item be produced in the US? No. Only the above listed products made primarily of iron or steel, permanently incorporated into the project must be produced in the US. For example trench boxes, scaffolding or equipment, which are removed from the project site upon completion of the project, are not required to be made of U.S. Iron or Steel. What is the definition of ‘municipal castings’?

Rev 06072017 3 | P a g e

Municipal castings are cast iron or steel infrastructure products that are melted and cast. They typically provide access, protection, or housing for components incorporated into utility owned drinking water, storm water, wastewater, and surface infrastructure. They are typically made of grey or ductile iron, or steel. Examples of municipal castings are: Access Hatches; Ballast Screen; Benches (Iron or Steel); Bollards; Cast Bases; Cast Iron Hinged Hatches (Square and Rectangular); Cast Iron Riser Rings; Catch Basin Inlet; Cleanout/Monument Boxes; Construction Covers and Frames; Curb and Corner Guards; Curb Openings; Detectable Warning Plates; Downspout Shoes (Boot, Inlet); Drainage Grates, Frames and Curb Inlets; Inlets; Junction Boxes; Lampposts; Manhole Covers, Rings and Frames, Risers; Meter Boxes; Service Boxes; Steel Hinged Hatches (Square and Rectangular); Steel Riser Rings; Trash receptacles; Tree Grates; Tree Guards; Trench Grates; and Valve Boxes, Covers, and Risers. What is ‘structural steel’? Structural steel is rolled flanged shapes, having at least one dimension of their cross-section three inches or greater, which are used in the construction of bridges, buildings, ships, railroad rolling stock, and for numerous other constructional purposes. Such shapes are designated as wide-flange shapes, standard I-beams, channels, angles, tees and zees. Other shapes include H-piles, sheet piling, tie plates, cross ties, and those for other special purposes. What is a ‘construction material’ for purposes of the AIS requirement? Construction materials are those articles, materials, or supplies made primarily of iron and steel, that are permanently incorporated into the project, not including mechanical and/or electrical components, equipment and systems. Some of these products may overlap with what is also considered “structural steel”. This includes, but is not limited to, the following products: wire rod, bar, angles, concrete reinforcing bar, wire, wire cloth, wire rope and cables, tubing, framing, joists, trusses, fasteners (i.e., nuts and bolts), welding rods, decking, grating, railings, stairs, access ramps, fire escapes, ladders, wall panels, dome structures, roofing, ductwork, surface drains, cable hanging systems, manhole steps, fencing and fence tubing, guardrails, doors, and stationary screens. What is not considered a ‘construction material’ for purposes of the AIS requirement? Mechanical and electrical components, equipment and systems are not considered construction materials. Mechanical equipment is typically that which has motorized parts and/or is powered by a motor. Electrical equipment is typically any machine powered by electricity and includes components that are part of the electrical distribution system. The following examples (including their appurtenances necessary for their intended use and operation) are NOT considered construction materials: pumps, motors, gear reducers, drives (including variable frequency drives (VFDs)), electric/pneumatic/manual accessories used to operate valves (such as electric valve actuators), mixers, gates, motorized screens (such as traveling screens), blowers/aeration equipment, compressors, meters, sensors, controls and switches, supervisory control and data acquisition (SCADA), membrane bioreactor systems, membrane

filtration systems, filters, clarifiers and clarifier mechanisms, rakes, grinders, disinfection systems, presses (including belt presses), conveyors, cranes, HVAC (excluding ductwork), water heaters, heat exchangers, generators, cabinetry and housings (such as electrical boxes/enclosures), lighting fixtures, electrical conduit, emergency life systems, metal office furniture, shelving, laboratory equipment, analytical instrumentation, and dewatering equipment. If the iron or steel is produced in the US, may other steps in the manufacturing process take place outside of the US, such as assembly? No. Production in the US of the iron or steel used in a listed product requires that all manufacturing processes must take place in the United States, except metallurgical processes involving refinement of steel additives. What processes must occur in the US to be compliant with the AIS requirement for reinforced precast concrete? While reinforced precast concrete may not be at least 50% iron or steel, in this particular case, the reinforcing bar and wire must be produced in the US and meet the same standards as for any other iron or steel product. Additionally, the casting of the concrete product must take place in the US. The cement and other raw materials used in concrete production are not required to be of domestic origin. If the reinforced concrete is cast at the construction site, the reinforcing bar and wire are considered to be a construction material and must be produced in the US. How do international trade agreements affect the implementation of the AIS requirements? The AIS provision applies in a manner consistent with United States obligations under international agreements. Typically, these obligations only apply to direct procurement by the entities that are signatories to such agreements. In general, SRF assistance recipients are not signatories to such agreements, so these agreements have no impact on this AIS provision. In the few instances where such an agreement applies to a municipality, that municipality is under the obligation to determine its applicability and requirements and document the actions taken to comply for the State. Compliance Either a Step “Process” Certification letter or “Final Delivered Product” Certification letter must be provided by the General Contractor with all shop drawings containing AIS. OPTION 1: STEP PROCESS CERTIFICATION The step “Process” certification is a method to ensure that producers adhere to the AIS requirement and assistance recipients (District) can verify that products comply with the AIS requirement. The process also establishes accountability and better enables States to take enforcement actions against violators. Step “Process” certification creates a paper trail which documents the location of the manufacturing process involved with the production of steel and iron materials. A step “process” certification requires each handler (supplier, fabricator, manufacturer, processor, etc) of the iron

Rev 06072017 5 | P a g e

and steel products to certify that their step in the process was domestically performed. Each time a step in the manufacturing process takes place, the manufacturer delivers its work along with a certification of its origin. A certification can be quite simple. It includes the name of the manufacturer, the location of the manufacturing facility where the product or process took place (not its headquarters), a description of the product or item being delivered, and a signature by a manufacturer’s responsible party. Attached to this appendix is a sample “Step Process” certification letter. Step Process certification letters are to be submitted by the General Contractor with the shop drawing submittal. OPTION 2 – DELIVERED PRODUCT CERTIFICATION Alternatively, the final manufacturer that delivers the iron or steel product to the worksite, vendor, or contractor, may provide a “delivered product” certification asserting that all manufacturing processes occurred in the US. Attached to this appendix is a sample “Final Delivered Product” certification letter, which is to be submitted by the General Contractor with the shop drawing submittal. While this type of certification may be acceptable, it may not provide the same degree of assurance. Additional documentation may be needed if the certification is lacking important information. Step certification is the best practice. How should a State ensure assistance recipients (District) are complying with the AIS requirement? In addition to collecting the certification letters with the shop drawing submittals, the State may conduct site visits of projects during construction and review documentation demonstrating proof of compliance which the assistance recipient (District) has gathered. What happens if a State or EPA finds a non-compliant iron and/or steel product permanently incorporated in the project? If a potentially non-compliant product is identified, the State should notify the assistance recipient of the apparent unauthorized use of the non-domestic component, including a proposed corrective action, and should be given the opportunity to reply. If unauthorized use is confirmed, the State can take one or more of the following actions:

• request a waiver where appropriate; • require the removal of the non-domestic item; or • withhold payment for all or part of the project.

Only EPA can issue waivers to authorize the use of a non-domestic item. EPA may use remedies available to it under the Clean Water Act, the Safe Drinking Water Act, and 40 CFR part 31 grant regulations, in the event of a violation of a grant term and condition. It is recommended that the State work collaboratively with EPA to determine the appropriate corrective action, especially in cases where the State is the one who identifies the item in noncompliance or there is a disagreement with the assistance recipient.

If fraud, waste, abuse, or any violation of the law is suspected, the Office of Inspector General (OIG) should be contacted immediately. The OIG can be reached at 1-11-888-546-8740 or [email protected]. More information can be found at this website: http://www.epa.gov/oig/hotline.htm. Waivers To view Approved, Denied or Draft Waivers, go to: http://water.epa.gov/grants_funding/aisrequirement.cfm Note: A National waiver was issued by the EPA for De Minimis incidental components; follow the link above for additional information. Waiver Process The statute permits EPA to issue waivers for a case or category of cases where EPA finds (1) that applying these requirements would be inconsistent with the public interest; (2) iron and steel products are not produced in the US in sufficient and reasonably available quantities and of a satisfactory quality; or (3) inclusion of iron and steel products produced in the US will increase the cost of the overall project by more than 25 percent. In order to implement the AIS requirements, EPA has developed an approach to allow for effective and efficient implementation of the waiver process to allow projects to proceed in a timely manner. The framework will allow States, on behalf of the assistance recipients, to apply for waivers of the AIS requirement directly to EPA Headquarters. Only waiver requests received from states will be considered. Pursuant to the Act, EPA has the responsibility to make findings as to the issuance of waivers to the AIS requirements. If a waiver is needed, Contractor to notify the District as soon as possible to review the request. Definitions The following terms are critical to the interpretation and implementation of the AIS requirements and apply to the process described in this memorandum: Reasonably Available Quantity: The quantity of iron or steel products is available or will be available at the time needed and place needed, and in the proper form or specification as specified in the project plans and design. Satisfactory Quality: The quality of iron or steel products, as specified in the project plans and designs. Assistance Recipient: A borrower or grantee (District) that receives funding from a State CWSRF or DWSRF program.

Guidelines for Meeting the California State Revolving Fund (CASRF) Programs

(Clean Water and Drinking Water SRF) Disadvantaged Business Enterprise Requirements

The Disadvantaged Business Enterprise (DBE) Program is an outreach, education, and objectives program designed to increase the participation of DBEs in the Clean Water State Revolving Fund (CWSRF), Drinking Water State Revolving Fund (DWSRF) Programs and the California State Revolving Fund (CASRF).

How to Achieve the Purpose of the Program

Recipients of CWSRF/DWSRF financing that are subject to the DBE requirements (recipients) are required to seek, and are encouraged to use, DBEs for their procurement needs. Recipients should award a "fair share" of sub-agreements to DBEs. This applies to all sub-agreements for equipment, supplies, construction, and services.

The key functional components of the DBE Program are as follows:

• Fair Share Objectives • DBE Certification • Six Good Faith Efforts • Contract Administration Requirements • DBE Reporting

Disadvantaged Business Enterprises are:

• Entities owned and/or controlled by socially and economically disadvantaged

individuals as described by Title X of the Clean Air Act Amendments of 1990 (42 U.S.C. 7601 note) (10% statute), and Public Law 102-389 (42 U.S.C. 4370d) (8% statute), respectively;

• Minority Business Enterprise (MBE) - entities that are at least 51% owned and/or

controlled by a socially and economically disadvantaged individual as described by Title X of the Clean Air Act Amendments of 1990 (42 U.S.C. 7601 note), and Public Law 102-389 (42 U.S.C. 4370d), respectively;

• Women Business Enterprise (WBE) - entities that are at least 51% owned and/or controlled by women;

• Small Business Enterprise (SBE);

• Small Business in a Rural Area (SBRA);

• Labor Surplus Area Firm (LSAF); or

http://www.waterboards.ca.gov/

• Historically Underutilized Business (HUB) Zone Small Business Concern or a

concern under a successor program.

Certifying DBE Firms:

Under the DBE Program, entities can no longer self-certify and contractors and sub-contractors must be certified at bid opening. Contractors and sub-contractors must provide to the CASRF recipient proof of DBE certification. Certifications will be accepted from the following:

• The U.S. Environmental Protection Agency (USEPA) • The Small Business Administration (SBA) • The Department of Transportation’s State implemented DBE Certification Program (with U.S. citizenship) • Tribal, State and Local governments • Independent private organization certifications

If an entity holds one of these certifications, it is considered acceptable for establishing status under the DBE Program.

Six Good Faith Efforts and (GFE) Reporting Requirements

All CWSRF/DWSRF financing recipients are required to complete and ensure that the prime contractor complies with the GFE below to ensure that DBEs have the opportunity to compete for financial assistance dollars.

1. Ensure DBEs are made aware of contracting opportunities to the fullest extent practical

through outreach and recruitment activities. For Tribal, State and Local Government Recipients, this will include placing DBEs on solicitation lists and soliciting them whenever they are potential sources.

2. Make information on forthcoming opportunities available to DBEs. Posting

solicitations for bids or proposals for a minimum of 30 calendar days in a local newspaper, before the bid opening date.

3. Consider in the contracting process whether firms competing for large contracts could subcontract with

DBEs.

4. Encourage contracting with a group of DBEs when a contract is too large for one firm to handle individually.

5. Use the services of the SBA and/or Minority Business Development Agency (MBDA) of the

US Department of Commerce.

6. If the prime contractor awards subcontracts, require the prime contractor to take the above steps.

GFE FORMS TO BE SUBMITTED WITH BID Bidders shall submit the following forms with their bid to be considered a responsive bidder:

APPENDIX HDavis Bacon Requirements

DAVIS BACON REQUIREMENTS

G-1 2011 cap 14xii10

(a) The Recipient shall insert in full in any contract in excess of $2,000 which is entered into

for the actual construction, alteration and/or repair, including painting and decorating, of a treatment work under the CWSRF the following clauses:

(1) Minimum wages.

(i) All laborers and mechanics employed or working upon the site of the

work, will be paid unconditionally and not less often than once a week, and without subsequent deduction or rebate on any account (except such payroll deductions as are permitted by regulations issued by the Secretary of Labor under the Copeland Act (29 CFR part 3)), the full amount of wages and bona fide fringe benefits (or cash equivalents thereof) due at time of payment computed at rates not less than those contained in the wage determination of the Secretary of Labor which is attached hereto and made a part hereof, regardless of any contractual relationship which may be alleged to exist between the contractor and such laborers and mechanics.

Contributions made or costs reasonably anticipated for bona fide fringe benefits under section 1(b)(2) of the Davis-Bacon Act on behalf of laborers or mechanics are considered wages paid to such laborers or mechanics, subject to the provisions of paragraph (a)(1)(iv) of this section; also, regular contributions made or costs incurred for more than a weekly period (but not less often than quarterly) under plans, funds, or programs which cover the particular weekly period, are deemed to be constructively made or incurred during such weekly period. Such laborers and mechanics shall be paid the appropriate wage rate and fringe benefits on the wage determination for the classification of work actually performed, without regard to skill, except as provided in § 5.5(a)(4). Laborers or mechanics performing work in more than one classification may be compensated at the rate specified for each classification for the time actually worked therein: Provided, that the employer's payroll records accurately set forth the time spent in each classification in which work is performed. The wage determination (including any additional classification and wage rates conformed under paragraph (a)(1)(ii) of this section) and the Davis-Bacon poster (WH-1321) shall be posted at all times by the contractor and its subcontractors at the site of the work in a prominent and accessible place where it can be easily seen by the workers.

The Recipient may obtain wage determinations from the U.S. Department of Labor’s web site, www.dol.gov. .

(ii)(A) The Recipient, on behalf of EPA, shall require that any class of laborers

or mechanics, including helpers, which is not listed in the wage determination and which is to be employed under the contract shall be classified in conformance with the wage determination. The State award official shall approve a request for an additional classification and wage rate and fringe benefits therefore only when the following criteria have been met:

(1) The work to be performed by the classification requested is not

performed by a classification in the wage determination; and

http://www.dol.gov/


G-2 2011 cap 14xii10

(2) The classification is utilized in the area by the construction industry; and

(3) The proposed wage rate, including any bona fide fringe benefits,

bears a reasonable relationship to the wage rates contained in the wage determination.

(B) If the contractor and the laborers and mechanics to be employed in the

classification (if known), or their representatives, and the Recipient agree on the classification and wage rate (including the amount designated for fringe benefits where appropriate), documentation of the action taken and the request, including the local wage determination shall be sent by the Recipient to the State award official. The State award official will transmit the report, to the Administrator of the Wage and Hour Division, Employment Standards Administration, U.S. Department of Labor, Washington, DC 20210 and to the EPA DB Regional Coordinator concurrently. The Administrator, or an authorized representative, will approve, modify, or disapprove every additional classification request within 30 days of receipt and so advise the State award official or will notify the State award official within the 30-day period that additional time is necessary.

(C) In the event the contractor, the laborers or mechanics to be employed in the classification or their representatives, and the and the Recipient do not agree on the proposed classification and wage rate (including the amount designated for fringe benefits, where appropriate), the award official shall refer the request, and the local wage determination, including the views of all interested parties and the recommendation of the State award official, to the Administrator for determination. The request shall be sent to the EPA Regional Coordinator concurrently. The Administrator, or an authorized representative, will issue a determination within 30 days of receipt of the request and so advise the contracting officer or will notify the contracting officer within the 30-day period that additional time is necessary.

(D) The wage rate (including fringe benefits where appropriate) determined

pursuant to paragraphs (a)(1)(ii)(B) or (C) of this section, shall be paid to all workers performing work in the classification under this contract from the first day on which work is performed in the classification.

(iii) Whenever the minimum wage rate prescribed in the contract for a class

of laborers or mechanics includes a fringe benefit which is not expressed as an hourly rate, the contractor shall either pay the benefit as stated in the wage determination or shall pay another bona fide fringe benefit or an hourly cash equivalent thereof.

(iv) If the contractor does not make payments to a trustee or other third

person, the contractor may consider as part of the wages of any laborer or mechanic the amount of any costs reasonably anticipated in providing bona fide fringe benefits under a plan or program, Provided, That the Secretary of Labor has found, upon the written request of the contractor, that the applicable standards of the Davis-Bacon Act have been met. The Secretary of Labor may require the contractor to set aside in a separate account assets for the meeting of obligations under the plan or program.


G-3 2011 cap 14xii10

(2) Withholding. The Recipient shall upon written request of the EPA Award Official

or an authorized representative of the Department of Labor, withhold or cause to be withheld from the contractor under this contract or any other Federal contract with the same prime contractor, or any other federally-assisted contract subject to Davis-Bacon prevailing wage requirements, which is held by the same prime contractor, so much of the accrued payments or advances as may be considered necessary to pay laborers and mechanics, including apprentices, trainees, and helpers, employed by the contractor or any subcontractor the full amount of wages required by the contract. In the event of failure to pay any laborer or mechanic, including any apprentice, trainee, or helper, employed or working on the site of the work, all or part of the wages required by the contract, the (Agency) may, after written notice to the contractor, sponsor, applicant, or owner, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds until such violations have ceased.

(3) Payrolls and basic records.

(i) Payrolls and basic records relating thereto shall be maintained by the

contractor during the course of the work and preserved for a period of three years thereafter for all laborers and mechanics working at the site of the work. Such records shall contain the name, address, and social security number of each such worker, his or her correct classification, hourly rates of wages paid (including rates of contributions or costs anticipated for bona fide fringe benefits or cash equivalents thereof of the types described in section 1(b)(2)(B) of the Davis-Bacon Act), daily and weekly number of hours worked, deductions made and actual wages paid. Whenever the Secretary of Labor has found under 29 CFR 5.5(a)(1)(iv) that the wages of any laborer or mechanic include the amount of any costs reasonably anticipated in providing benefits under a plan or program described in section 1(b)(2)(B) of the Davis-Bacon Act, the contractor shall maintain records which show that the commitment to provide such benefits is enforceable, that the plan or program is financially responsible, and that the plan or program has been communicated in writing to the laborers or mechanics affected, and records which show the costs anticipated or the actual cost incurred in providing such benefits. Contractors employing apprentices or trainees under approved programs shall maintain written evidence of the registration of apprenticeship programs and certification of trainee programs, the registration of the apprentices and trainees, and the ratios and wage rates prescribed in the applicable programs.

(ii)(A) The contractor shall submit weekly, for each week in which any contract work is performed, a copy of all payrolls to the Recipient, that is, the entity that receives the sub-grant or loan from the State capitalization grant recipient. Such documentation shall be available on request of the State Water Board or EPA. As to each payroll copy received, the Recipient shall provide written confirmation in a form satisfactory to the State indicating whether or not the project is in compliance with the requirements of 29 CFR 5.5(a)(1) based on the most recent payroll copies for the specified week. The payrolls shall set out accurately and completely all of the information required to be maintained under 29 CFR 5.5(a)(3)(i), except that full social security numbers and home addresses shall not be included on the weekly payrolls. Instead the payrolls shall only need to include an individually identifying number for each


G-4 2011 cap 14xii10

employee (e.g., the last four digits of the employee's social security number). The required weekly payroll information may be submitted in any form desired. Optional Form WH-347 is available for this purpose from the Wage and Hour Division Web site at http://www.dol.gov/esa/whd/forms/wh347instr.htm or its successor site. The prime contractor is responsible for the submission of copies of payrolls by all subcontractors. Contractors and subcontractors shall maintain the full social security number and current address of each covered worker, and shall provide them upon request to the Recipient for transmission to the State or EPA if requested by EPA, the State, the contractor, or the Wage and Hour Division of the Department of Labor for purposes of an investigation or audit of compliance with prevailing wage requirements. It is not a violation of this section for a prime contractor to require a subcontractor to provide addresses and social security numbers to the prime contractor for its own records, without weekly submission to the Recipient.

(B) Each payroll submitted shall be accompanied by a “Statement of

Compliance,” signed by the contractor or subcontractor or his or her agent who pays or supervises the payment of the persons employed under the contract and shall certify the following:

(1) That the payroll for the payroll period contains the information

required to be provided under § 5.5 (a)(3)(ii) of Regulations, 29 CFR part 5, the appropriate information is being maintained under § 5.5 (a)(3)(i) of Regulations, 29 CFR part 5, and that such information is correct and complete;

(2) That each laborer or mechanic (including each helper,

apprentice, and trainee) employed on the contract during the payroll period has been paid the full weekly wages earned, without rebate, either directly or indirectly, and that no deductions have been made either directly or indirectly from the full wages earned, other than permissible deductions as set forth in Regulations, 29 CFR part 3;

(3) That each laborer or mechanic has been paid not less than the

applicable wage rates and fringe benefits or cash equivalents for the classification of work performed, as specified in the applicable wage determination incorporated into the contract.

(C) The weekly submission of a properly executed certification set forth on

the reverse side of Optional Form WH-347 shall satisfy the requirement for submission of the “Statement of Compliance” required by paragraph (a)(3)(ii)(B) of this section.

(D) The falsification of any of the above certifications may subject the

contractor or subcontractor to civil or criminal prosecution under section 1001 of title 18 and section 231 of title 31 of the United States Code.

(iii) The contractor or subcontractor shall make the records required under

paragraph (a)(3)(i) of this section available for inspection, copying, or transcription by authorized representatives of the State, EPA or the Department of Labor, and shall permit such representatives to interview employees during working hours on the job. If the contractor or subcontractor fails to submit the required records or to make them

http://www.dol.gov/esa/whd/forms/wh347instr.htm


G-5 2011 cap 14xii10

available, the Federal agency or State may, after written notice to the contractor, sponsor, applicant, or owner, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds. Furthermore, failure to submit the required records upon request or to make such records available may be grounds for debarment action pursuant to 29 CFR 5.12.

(4) Apprentices and trainees.

(i) Apprentices. Apprentices will be permitted to work at less than the

predetermined rate for the work they performed when they are employed pursuant to and individually registered in a bona fide apprenticeship program registered with the U.S. Department of Labor, Employment and Training Administration, Office of Apprenticeship Training, Employer and Labor Services, or with a State Apprenticeship Agency recognized by the Office, or if a person is employed in his or her first 90 days of probationary employment as an apprentice in such an apprenticeship program, who is not individually registered in the program, but who has been certified by the Office of Apprenticeship Training, Employer and Labor Services or a State Apprenticeship Agency (where appropriate) to be eligible for probationary employment as an apprentice. The allowable ratio of apprentices to journeymen on the job site in any craft classification shall not be greater than the ratio permitted to the contractor as to the entire work force under the registered program. Any worker listed on a payroll at an apprentice wage rate, who is not registered or otherwise employed as stated above, shall be paid not less than the applicable wage rate on the wage determination for the classification of work actually performed. In addition, any apprentice performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. Where a contractor is performing construction on a project in a locality other than that in which its program is registered, the ratios and wage rates (expressed in percentages of the journeyman's hourly rate) specified in the contractor's or subcontractor's registered program shall be observed. Every apprentice must be paid at not less than the rate specified in the registered program for the apprentice's level of progress, expressed as a percentage of the journeymen hourly rate specified in the applicable wage determination. Apprentices shall be paid fringe benefits in accordance with the provisions of the apprenticeship program. If the apprenticeship program does not specify fringe benefits, apprentices must be paid the full amount of fringe benefits listed on the wage determination for the applicable classification. If the Administrator determines that a different practice prevails for the applicable apprentice classification, fringes shall be paid in accordance with that determination. In the event the Office of Apprenticeship Training, Employer and Labor Services, or a State Apprenticeship Agency recognized by the Office, withdraws approval of an apprenticeship program, the contractor will no longer be permitted to utilize apprentices at less than the applicable predetermined rate for the work performed until an acceptable program is approved.

(ii) Trainees. Except as provided in 29 CFR 5.16, trainees will not be

permitted to work at less than the predetermined rate for the work performed unless they are employed pursuant to and individually registered in a program which has received prior approval, evidenced by


G-6 2011 cap 14xii10

formal certification by the U.S. Department of Labor, Employment and Training Administration. The ratio of trainees to journeymen on the job site shall not be greater than permitted under the plan approved by the Employment and Training Administration. Every trainee must be paid at not less than the rate specified in the approved program for the trainee's level of progress, expressed as a percentage of the journeyman hourly rate specified in the applicable wage determination. Trainees shall be paid fringe benefits in accordance with the provisions of the trainee program. If the trainee program does not mention fringe benefits, trainees shall be paid the full amount of fringe benefits listed on the wage determination unless the Administrator of the Wage and Hour Division determines that there is an apprenticeship program associated with the corresponding journeyman wage rate on the wage determination which provides for less than full fringe benefits for apprentices. Any employee listed on the payroll at a trainee rate who is not registered and participating in a training plan approved by the Employment and Training Administration shall be paid not less than the applicable wage rate on the wage determination for the classification of work actually performed. In addition, any trainee performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. In the event the Employment and Training Administration withdraws approval of a training program, the contractor will no longer be permitted to utilize trainees at less than the applicable predetermined rate for the work performed until an acceptable program is approved.

(iii) Equal employment opportunity. The utilization of apprentices, trainees

and journeymen under this part shall be in conformity with the equal employment opportunity requirements of Executive Order 11246, as amended, and 29 CFR part 30.

(5) Compliance with Copeland Act requirements. The contractor shall comply with

the requirements of 29 CFR part 3, which are incorporated by reference in this contract.

(6) Subcontracts. The contractor or subcontractor shall insert in any subcontracts the

clauses contained in 29 CFR 5.5(a)(1) through (10) and such other clauses as the EPA determines may by appropriate, and also a clause requiring the subcontractors to include these clauses in any lower tier subcontracts. The prime contractor shall be responsible for the compliance by any subcontractor or lower tier subcontractor with all the contract clauses in 29 CFR 5.5.

(7) Contract termination: debarment. A breach of the contract clauses in 29 CFR 5.5

may be grounds for termination of the contract, and for debarment as a contractor and a subcontractor as provided in 29 CFR 5.12.

(8) Compliance with Davis-Bacon and Related Act requirements. All rulings and

interpretations of the Davis-Bacon and Related Acts contained in 29 CFR parts 1, 3, and 5 are herein incorporated by reference in this contract.

(9) Disputes concerning labor standards. Disputes arising out of the labor standards

provisions of this contract shall not be subject to the general disputes clause of this contract. Such disputes shall be resolved in accordance with the procedures of the Department of Labor set forth in 29 CFR parts 5, 6, and 7. Disputes within the meaning of this clause include disputes between the contractor (or any of its


G-7 2011 cap 14xii10

subcontractors) and the Recipient, State, EPA, the U.S. Department of Labor, or the employees or their representatives.

(10) Certification of eligibility.

(i) By entering into this contract, the contractor certifies that neither it (nor

he or she) nor any person or firm who has an interest in the contractor's firm is a person or firm ineligible to be awarded Government contracts by virtue of section 3(a) of the Davis-Bacon Act or 29 CFR 5.12(a)(1).

(ii) No part of this contract shall be subcontracted to any person or firm

ineligible for award of a Government contract by virtue of section 3(a) of the Davis-Bacon Act or 29 CFR 5.12(a)(1).

(iii) The penalty for making false statements is prescribed in the U.S.

Criminal Code, 18 U.S.C. 1001. 2. Contract Provision for Contracts in Excess of $100,000.

(a) Contract Work Hours and Safety Standards Act. The Recipient shall insert the

following clauses set forth in paragraphs (a)(1), (2), (3), and (4) of this section

in full in any contract in an amount in excess of $100,000 and subject to the

overtime provisions of the Contract Work Hours and Safety Standards Act. These

clauses shall be inserted in addition to the clauses required by Section 1, above

or 29 CFR 4.6. As used in this paragraph, the terms laborers and mechanics

include watchmen and guards.

(1) Overtime requirements. No contractor or subcontractor contracting for any part of

the contract work which may require or involve the employment of laborers or mechanics shall require or permit any such laborer or mechanic in any workweek in which he or she is employed on such work to work in excess of forty hours in such workweek unless such laborer or mechanic receives compensation at a rate not less than one and one-half times the basic rate of pay for all hours worked in excess of forty hours in such workweek.

(2) Violation; liability for unpaid wages; liquidated damages. In the event of any

violation of the clause set forth in paragraph (b)(1) of this section the contractor and any subcontractor responsible therefore shall be liable for the unpaid wages. In addition, such contractor and subcontractor shall be liable to the United States (in the case of work done under contract for the District of Columbia or a territory, to such District or to such territory), for liquidated damages. Such liquidated damages shall be computed with respect to each individual laborer or mechanic, including watchmen and guards, employed in violation of the clause set forth in paragraph (b)(1) of this section, in the sum of $10 for each calendar day on which such individual was required or permitted to work in excess of the standard workweek of forty hours without payment of the overtime wages required by the clause set forth in paragraph (b)(1) of this section.

(3) Withholding for unpaid wages and liquidated damages. The Recipient shall upon

the request of the EPA Award Official or an authorized representative of the Department of Labor, withhold or cause to be withheld, from any moneys payable on account of work performed by the contractor or subcontractor under any such contract or any other Federal contract with the same prime contractor, or any other federally-assisted contract subject to the Contract Work Hours and Safety Standards Act, which is held by the same prime contractor, such sums as may be determined to be necessary to satisfy any liabilities of such contractor or


G-8 2011 cap 14xii10

subcontractor for unpaid wages and liquidated damages as provided in the clause set forth in paragraph (b)(2) of this section.

(4) Subcontracts. The contractor or subcontractor shall insert in any subcontracts the

clauses set forth in paragraph (b)(1) through (4) of this section and also a clause requiring the subcontractors to include these clauses in any lower tier subcontracts. The prime contractor shall be responsible for compliance by any subcontractor or lower tier subcontractor with the clauses set forth in paragraphs (b)(1) through (4) of this section.

(c) In addition to the clauses contained in Section 1, above, in any contract subject

only to the Contract Work Hours and Safety Standards Act and not to any of the

other statutes cited in 29 CFR 5.1, the Recipient shall insert a clause requiring

that the contractor or subcontractor shall maintain payrolls and basic payroll

records during the course of the work and shall preserve them for a period of

three years from the completion of the contract for all laborers and mechanics,

including guards and watchmen, working on the contract. Such records shall

contain the name and address of each such employee, social security number,

correct classifications, hourly rates of wages paid, daily and weekly number of

hours worked, deductions made, and actual wages paid. Further, the Recipient

shall insert in any such contract a clause providing that the records to be

maintained under this paragraph shall be made available by the contractor or

subcontractor for inspection, copying, or transcription by authorized

representatives of the (write the name of agency) and the Department of Labor,

and the contractor or subcontractor will permit such representatives to interview

employees during working hours on the job. 3. Compliance Verification

(a) The Recipient shall periodically interview a sufficient number of employees entitled to DB prevailing wages (covered employees) to verify that contractors or subcontractors are paying the appropriate wage rates. As provided in 29 CFR 5.6(a)(6), all interviews must be conducted in confidence. The Recipient must use Standard Form 1445 (SF 1445) or equivalent documentation to memorialize the interviews. Copies of the SF 1445 are available from EPA on request.

(b) The Recipient shall establish and follow an interview schedule based on its assessment

of the risks of noncompliance with DB posed by contractors or subcontractors and the duration of the contract or subcontract. At a minimum, the Recipient should conduct interviews with a representative group of covered employees within two weeks of each contractor or subcontractor’s submission of its initial weekly payroll data and two weeks prior to the estimated completion date for the contract or subcontract. The Recipient must conduct more frequent interviews if the initial interviews or other information indicates that there is a risk that the contractor or subcontractor is not complying with DB. The Recipient shall immediately conduct necessary interviews in response to an alleged violation of the prevailing wage requirements. All interviews shall be conducted in confidence.

(c) The Recipient shall periodically conduct spot checks of a representative sample of weekly

payroll data to verify that contractors or subcontractors are paying the appropriate wage rates. The Recipient shall establish and follow a spot check schedule based on its assessment of the risks of noncompliance with DB posed by contractors or subcontractors and the duration of the contract or subcontract. At a minimum, if practicable the Recipient shall spot check payroll data within two weeks of each contractor or subcontractor’s submission of its initial payroll data and two weeks prior to the completion date the contract or subcontract. The Recipient must conduct more


G-9 2011 cap 14xii10

frequent spot checks if the initial spot check or other information indicates that there is a risk that the contractor or subcontractor is not complying with DB. In addition, during the examinations the Recipient shall verify evidence of fringe benefit plans and payments thereunder by contractors and subcontractors who claim credit for fringe benefit contributions.

(d) The Recipient shall periodically review contractors and subcontractors use of apprentices

and trainees to verify registration and certification with respect to apprenticeship and training programs approved by either the U.S Department of Labor or a state, as appropriate, and that contractors and subcontractors are not using disproportionate numbers of, laborers, trainees and apprentices. These reviews shall be conducted in accordance with the schedules for spot checks and interviews described in Item 5(b) and (c) above.

(e) The Recipient must immediately report potential violations of the DB prevailing wage

requirements to the EPA DB contact listed above and to the appropriate DOL Wage and Hour District Office listed at http://www.dol.gov/esa/contacts/whd/america2.htm.

WDOL.gov User's Guide (Ver 6.0) A. Overview 1. WDOL.GOV - General a. Purpose: This website provides a single location for federal contracting officers to use in

obtaining appropriate Service Contract Act (SCA) and Davis-Bacon Act (DBA) wage determinations (WDs) for each official contract action - new solicitations, resolicitations, options, extensions, or any other action requiring the most current and applicable WD. The website is available to the general public as well. Guidance in selecting WDs from this website is provided in this WDOL.GOV User's Guide. Alternatively, contracting officers may also use the Department of Labor's (DOL's) "e98" website to submit a request for SCA WDs for use on official contract actions. In some instances, the WDOL.GOV Program will not contain the appropriate SCA WD and contracting officers will be directed to use DOL's e98 website in order to obtain the required SCA WD. DOL will either provide the contracting officer with an SCA WD through the e98 system or advise them that no wage determination is applicable to the contract. Questions pertaining to the application of contract labor standards or the selection of appropriate WDs for specific contract actions should be referred to the contracting officer or to the designated Agency Labor Advisor who, in turn, may refer the question to DOL. DOL has responsibility for final rulings regarding coverage and WDs under SCA and DBA. Questions pertaining to this website should be referred to the WDOL.GOV Webmaster. Questions pertaining to DOL's e98 website should be referred to DOL.

b. Responsibility: The WDOL.GOV Program and this User's Guide does not relieve the

contracting officer, or other program user, of the requirement to carefully review the contract or solicitation, the Federal Acquisition Regulation (FAR) and its Supplements, other federal agency acquisition regulations, or the DOL regulations related to these actions. If DOL discovers and determines, whether before or after contract award, that a contracting officer failed to include an appropriate SCA or DBA WD in a covered contract, the contracting officer, within 30 days of notification by DOL, shall include in the contract the applicable WD issued by DOL. (Reference Title 29 CFR Part 1, Section 1.6(f); Part 4, Sections 4.5(c) (2) and 4.101(b); and FAR Part 22, Subsection 22.404-9 and Section 22.1015).

c. Description of the WDOL Program: The WDOL.GOV Program is designed to direct the user to the appropriate WD for a specific contract action. The user must complete a series of menus (questions) pertaining to that contract action in order to obtain a copy of the applicable WD. If the user does not enter the correct information in the menu process for the specific contract action, they may receive an incorrect WD for the proposed contract action. The WDOL.gov program is best used with Internet Explorer Version 5.0 or greater capability. Questions pertaining to a specific contract action should be referred to the responsible contracting officer. Caution: Users should know the details of the solicitation, including the statement of work, predecessor contract(s) if any, locality (state and county) where the work will be performed, and the contracting agency and officer, in order to select the correct SCA or DBA WD for any specific contract action.

d. Who May Use the WDOL.GOV Program: Federal, state, and local contracting agencies,

contractors, labor organizations, contractor associations, employees, and all other interested parties may use the WDOL.GOV Program. Review the User's Guide carefully, and use the resources on the WDOL.GOV Library Page to learn about the application of contract labor standards, and contact the specific contracting officer and/or the agency labor advisor for advice and guidance. Users should note that the only WDs applicable to a particular solicitation or contract are those that have been incorporated by the contracting officer in that contract action.

e. Using DOL's "e98" Process: Contracting officers may elect to use the e98 request form

for any SCA-covered contract action. Also, if a contracting officer cannot determine an appropriate SCA WD within the WDOL.GOV database for use in an official federal contract action, the contracting officer must request an official SCA WD from DOL by completing the "e98" at DOL's website. Most requests are processed immediately. Some requests will require research and DOL may need additional time to respond. DOL's "e98" website is solely for the use of federal contracting officers. General inquiries from interested parties may be directed to [email protected].

B. Service Contract Act: Regulations and Requirements 1. SCA - Statute and Regulations. The WDOL.GOV Library Page contains a link to DOL's

website and to a copy of the statute (41 U.S.C. 351-358) and the pertinent SCA regulations (Title 29 CFR Part 4, Labor Standards for Federal Service Contracts). Other DOL regulations address related requirements, for example: Title 29 CFR Part 541 for the definition of the exemption for "executive, administrative, or professional employees"; Title 29 CFR Part 785 for regulations defining "hours worked"; Title 29 CFR Part 531 for regulations defining "wages"; and Title 29 CFR Part 778 for regulations defining overtime or premium pay for workers working in excess of a standard workweek.

2. Federal Acquisition Regulations (FAR) and Supplements. The WDOL.GOV Library Page contains links to federal acquisition regulations including the supplements issued by each federal contracting agency. WDOL.GOV users are urged to familiarize themselves not only with DOL regulations, but also with the pertinent acquisition regulations pertaining to specific contract actions (including statements of work, modifications to the contract, options, extensions, and similar actions).

3. Application of SCA. SCA establishes standards for prevailing compensation and safety

and health protections for employees performing work for contractors and subcontractors on service contracts entered into with the federal government and with the District of Columbia. SCA provisions are applicable to contracts the principal purpose of which is to

provide services in the United States through the use of service employees. 4. SCA Wage and Benefit Requirements a. For service contracts $2,500 and under, SCA Section 2(b)(1) requires payment of the

minimum wage in the Fair Labor Standards Act (reference FAR Section 22.1002-4). b. For service contracts over $2,500, SCA requires the contracting officer to incorporate

into the contract a requirement to pay prevailing wages and benefits issued by DOL in the form of "wage determinations" (reference FAR Sections 22.1006, 22.1007 & 22.1008).

5. Types of SCA WDs. The WDOL.GOV database contains the latest WDs developed by

the DOL. The SCA database is updated each Tuesday (by 1:00 pm ET) with all current revisions. DOL issues two types of SCA WDs - prevailing wage WDs, and WDs based on Collective Bargaining Agreements (CBAs) covered by SCA Section 4(c).

a. Prevailing Wage SCA WDs. There are several sub-types of "prevailing" WDs as follows:

1. Standard WDs are generic WDs listing over 300 different classifications (from

several occupational groups, e.g., Clerical and Administrative, Technical Occupations, Information and Arts, Transportation). Each Standard WD reflects wages and fringe benefits found by DOL to be prevailing in a specific locality1..

The wage rates and health and welfare (H&W) rates are the same on each Standard WD for a locality. However, the method by which a contractor must comply with the H&W rate is different2. Compliance with the H&W rate on all "odd numbered" Standard WDs (i.e., WD No. 2005-2103 or WD No. 2005-2113) requires payment of the minimum H&W rate for each hour paid for each employee, up to a maximum of 40 hours per week. [See 29 CFR 4.175(a)] Compliance with the H&W rate on all "even numbered" Standard WDs (i.e., WD No. 2005-2104 or WD No. 2005-2114) requires the contractor to contribute an average of the stated H&W rate per hour, computed on the basis of all hours worked by service employees on the contract. [See 29 CFR 4.175(b)] The latter method, "average cost H&W", was specified on WDs with the old "high benefit" rate that was grandfathered as part of the 1996 DOL rulemaking. (See "All Agency Memorandum No. 188" dated May 22, 1997 on the WDOL.gov Library Page and 29 CFR 4.52(d)). When the survey data for odd numbered ("per employee") WD exceeded the grandfathered "high benefit" rate of $2.56 per hour, the Department of Labor increased the fringe benefit rates on all WDs to reflect the new survey data; however, DOL also retained the two different methods for determining compliance. The averaging H&W methodology continued to be applied to contracts for which the old $2.56 high benefit rate had been applicable (see AAM No. 196 on the WDOL.gov Library Page). When selecting a Standard WD, the contracting officer must select the Standard WD with the appropriate health and welfare method. The guidelines for selection are as follows: a. First Guideline: Were the services previously performed under a contract

that incorporated an even numbered Standard WD? If so, for all following contract periods and follow-on contracts for substantially the same services that will be performed in the same locality, select the even numbered Standard WD for that same locality. [Reference -- 29 CFR 4.52(d)] When following the current WD selection menu, this is the reason

for the question regarding whether the services were "performed under an SCA wage determination that ends in an even number".

b. Second Guideline: If the services were not previously performed under contract using an even numbered Standard WD, or if the services were not previously performed under an SCA-covered contract, then select the odd numbered Standard WD for that locality. When following the current WD selection menu, answering the menu questions correct should obtain the odd numbered WD response.

c. Hawaii. Because Hawaii state law requires the payment of health

insurance, SCA H&W rates are different in Hawaii, but the application of the two levels is the same as noted in the above paragraphs.

d. WDOL.gov "Selecting SCA WDs" process asks the user to identify if the

services were previously performed at the locality in an SCA-covered contract, and if in the preceding contract or contract period the Standard WD was odd or even numbered. Therefore, it is necessary to know the WD "history" of a service contract requirement, even if the contract was awarded or administered by a different contracting activity, including those that will be awarded by a different government agency. If you have any questions regarding the appropriate H&W level to select for a specific contract action, contact the contracting officer or the designated agency labor advisor for assistance.

2. Non-Standard WDs. Non-Standard WDs are issued by DOL to reflect prevailing

wages and benefits in specific service industries in designated localities. Non-Standard WDs may not be used in contracts for services other than those specified in the Non-Standard WD description; conversely, Standard WDs may not be used in contracts designated for Non-Standard WDs. In the WDOL.GOV Program selection process, the user will be asked to determine if the contract services are "non-standard" as designated by DOL. The menu will provide a drop-down listing of such designated Non-Standard services. The WDOL.GOV User's Guide provides a listing of non-standard services at "Appendix A, SCA Non-Standard WDs”.

3. Contract-Specific or Special SCA WDs. There are a few, unique service contracts where DOL will issue contract-specific wage and benefit rates under SCA. An example of a contract-specific WD is a sole-source contract with a county, state or municipality where wages and benefits are already established. The SCA WD applicable to such a contract will be the rates established by the sole-source contractor. (Not all sole-source contract actions are subject to a Contract-Specific WD; only those contracts awarded to contractors similar to government organizations.) If a contracting officer has determined that neither a Standard WD nor a Non-Standard WD is appropriate for a particular contract action, the contracting officer should request an appropriate contract specific or special WD from DOL using the e98 system. DOL has sole authority to determine the appropriate wage and benefit rates for each contract action and will either issue a WD reflecting such rates or notify the contracting agency that there is no wage determination applicable to the contract.

b. SCA WDs Based on Collective Bargaining Agreements (CBAs)

1. If a fully executed Collective Bargaining Agreement (CBA) has been established as the predecessor contractor's Collective Bargaining Agreement (CBA) as specified in 29 CFR 4.163(f) and that Collective Bargaining Agreement (CBA) is timely [see section 8 of this guide] received by the contracting officer, the contracting officer must prepare a Collective Bargaining Agreement (CBA) WD that references the Collective Bargaining Agreement (CBA) (by employer, union, contract number and effective dates) and incorporate into the successor contract action the Collective Bargaining Agreement (CBA) (complete copy of the Collective Bargaining Agreement (CBA) and all addenda) along with the Collective Bargaining Agreement (CBA) WD as a cover page. The Collective Bargaining Agreement (CBA) wage and benefit provisions become controlling for wage determination purposes under section 4(c) of the SCA. 29 CFR 4.163(f) states in pertinent part". 4(c) will be operative only if the employees who worked on the predecessor contract were actually paid in accordance with the wage and fringe benefit provisions of a predecessor contractor's collective bargaining agreement. Thus, for example, section 4(c) would not apply if the predecessor contractor entered into a collective bargaining agreement for the first time, which did not become effective until after the expiration of the predecessor contract." Furthermore, DOL All Agency Memorandum 159 provides that Collective Bargaining Agreement (CBA)s that contain prohibited contingencies will not be effective for section 4(c) purposes. Therefore, it is recommended that the Collective Bargaining Agreement (CBA) be carefully reviewed to determine if it should be effective for wage determination purposes under section 4(c) prior to utilization of the WDOL process for creating a Collective Bargaining Agreement (CBA)-based wage determination. Thus the Collective Bargaining Agreement (CBA) should be reviewed for (1) timeliness, (2) that it is properly signed & executed by both parties to the Collective Bargaining Agreement (CBA), (3) that it has been properly established as the predecessor contractor’s Collective Bargaining Agreement (CBA) under which service employees were paid in the prior period of contract performance, (4) that it does not contain prohibited contingencies per DOL's AAM #159, (5) and that it has been reviewed for possible "variance" under FAR 22.1013 & 22.1021. Lastly, it is important to note that a contractor may be both the predecessor contractor and the successor contractor for wage determination purposes, particularly where option periods and extensions are issued. It is not necessary to send a copy of the Collective Bargaining Agreement (CBA) to DOL. The WDOL.gov database will not contain a copy of the Collective Bargaining Agreement (CBA) itself; it will only retain copies of the cover Collective Bargaining Agreement (CBA) WDs. Contractors and other WDOL.gov users must review specific solicitations or contracts (or contact the contracting officer) in order to determine if a particular Collective Bargaining Agreement (CBA) is applicable under SCA to that action.

2. The WDOL.gov Program menu includes a form for the contracting officer to

complete in order to prepare the cover Collective Bargaining Agreement (CBA) WD for each specific contract action, as required by SCA. The contracting officer must prepare a separate Collective Bargaining Agreement (CBA) WD for each SCA-covered Collective Bargaining Agreement (CBA) applicable to a contract action (including separate Collective Bargaining Agreement (CBA) WDs for prime contractor and for subcontractor(s)).

6. Monitoring the WDOL Program for SCA WD Revisions. a. Effective SCA WD revisions are those WDs considered received timely by the

contracting agency. See Section 7 of this guide for the timeliness criteria. b. Effective SCA WDs are required to be incorporated into contracts or contract actions.

That date will be found as a header at the top of the WD obtained via WDOL. c. Under the WDOL.GOV Program, "receipt" date of a new or revised SCA WD is the first

date at which that WD appears on the WDOL.GOV Program SCA Database. d. Under the WDOL Program, DOL will publish all SCA WD revisions for a given week on

the WDOL.GOV Program database each Tuesday. e. The contracting officer must monitor the WDOL.GOV Program SCA Database regularly

to determine if a selected WD has been revised and may be applicable (timely) to the contract action.

f. WDOL.GOV ALERT SYSTEM. To ensure that the contracting officer (or other

interested party) is aware of revisions made by DOL to SCA WDs (Standard WDs and Non-Standard WDs) selected for a specific contract action, the WDOL.GOV user may register for automatic email notification of such revisions. Upon selection of an appropriate SCA Standard or Non-Standard WD, the user will be offered the opportunity to request email notice of future revisions for a specific period of time, or until a specific date. Contracting officers are encouraged to request this automatic notification process in order to be aware of timely revisions applicable to contract actions. 1. At the Alert Service menu, the user will be asked to provide an email address for

the WDOL.gov to use in providing notification of a revision to a WD. The user may also provide an "alert identifier" which will appear in the WDOL.gov notification and will assist the user in relating the newly revised WD to a specific contract or solicitation, or other area of interest.

2. Users requesting the Alert Service will receive an email notice each time the selected SCA WD is revised until the Alert Service request expires. CAUTION: The Alert Service does not relieve the contracting officer of the obligation under SCA and its regulations to use timely received new or revised SCA WDs in contract actions.

g. Archived SCA WDs. Once DOL revises an SCA WD, the most current revision will be published on the WDOL.GOV database. Prior revisions, no longer current, will be maintained in the "Archived SCA WD" database for information purposes only. Contracting officers should not use an archived WD in a contract action without prior approval of DOL. Contact DOL at telephone number 866-487-9423.

7. Timely Receipt of New or Revised SCA WDs (Title 29 CFR Part 4, Section 4.5 and FAR

Section 22.1012). a. For contract actions resulting from other than sealed bidding:

1. A revised SCA WD shall be effective if it is received by the contracting agency before date of award (or date of modification for an option or extension).

2. If a revised WD is received after award, it shall NOT be effective if contract

performance starts less than 30 days from date of award or modification.

3. If a revised WD is received after award and performance starts more than 30 days from award or modification date, the WD (or Collective Bargaining Agreement (CBA)) will be effective if received no later than 10 days prior to start of performance.

4. With reference to SCA-covered Collective Bargaining Agreement (CBA)s, the

contracting officer must provide written notification to unions and contractors (in accordance with Title 29, CFR Part 4, Section 4.1b(b)(3), and FAR Section 22.1010) of the pending contract action and estimated date. A sample letter for notification is provided at WDOL.GOV User's Guide, Appendix B, FAR 22.1010 Notification“.

b. For contract actions resulting from sealed bidding: 1. A revised SCA WD shall NOT be effective if received by the contracting agency

less than 10 days prior to opening of bids, unless there is sufficient time to amend the solicitation and incorporate the revised WD.

8. Timely receipt of Collective Bargaining Agreement (CBA)s (Title 29 CFR Part 4,

Section 4.1(b) and FAR Section 22.1012). a. The obligation of a successor contractor to pay its employees no less than the wages and

fringe benefits required under the predecessor contractor's Collective Bargaining Agreement (CBA) is a statutory requirement of SCA Section 4(c). DOL has applied a limitation on the self-executing aspects of Section 4(c) (reference Title 29 CFR Part 4, Section 4.1(b)). This limitation only applies, however, if the contracting officer has given both the incumbent (predecessor) contractor and the employees' collective bargaining representative written notification at least 30 days in advance of all estimated procurement dates. A sample letter for notification is provided at Appendix B, "FAR Section 22.1010 Notification".

b. For contract actions resulting from other than sealed bidding: 1. A revised Collective Bargaining Agreement (CBA) shall apply to the successor

contract if it is received by the contracting agency before the date of award (or date of modification for an option or extension).

2. If a Collective Bargaining Agreement (CBA) is received after award, it shall NOT apply to the successor contract if contract performance starts less than 30 days from date of award or modification.

3. If a Collective Bargaining Agreement (CBA) is received after award and performance starts more than 30 days from award or modification date, the Collective Bargaining Agreement (CBA) shall apply to the successor contract if received no later than 10 days prior to start of performance.

c. For contract actions resulting from sealed bidding: 1. A revised Collective Bargaining Agreement (CBA) shall NOT apply to the

successor contract if received by the contracting agency less than 10 days prior to opening of bids, unless there is sufficient time to amend the solicitation and incorporate the revised WD.

9. Conformances (Requesting Authorization of Additional Classification and Rate). DOL

issues WDs under SCA using available statistical data on prevailing wages and benefits in a locality. On occasion, the WD does not provide a rate for a particular occupation needed in the performance of the contract. Because of this, SCA provisions contain a conformance procedure for the purpose of establishing a SCA-enforceable wage and benefit rate for missing occupational classifications.

a. Contractors are responsible for determining that the employees performing work

on a contract are in fact performing duties that fall within one or more of the occupational classifications listed on the applicable SCA WD. If a classification considered necessary for performance of the work is missing from the WD applicable to the contract, the awarded contractor must initiate a request for approval of a proposed wage and benefit rate. Generally, the contractor initiates the request by preparing an SF-1444, Request for Authorization of Additional Classification and Rate, at the time of employment of the unlisted classification. (Reference Title 29 CFR Part 4, Section 4.6(b) and FAR 22.1019) The contractor completes blocks 2 through 15 on the form. Requests may be submitted without the form, but must contain the required information.

b. Contractors must request employees, if present, or their designated representative, to sign block 16 noting the employee's concurrence or disagreement with the contractor's proposed wage and benefit rate. A statement supporting a recommendation for different rates may accompany any indication of disagreement. The "designated representative" is generally a union representative; it cannot be the contractor's representative or personnel officer.

c. The contractor submits the completed SF-1444 to the contracting officer. The contracting officer reviews the form for completeness, and signs the agency's concurrence or disagreement with the contractor's proposal. A statement supporting a recommendation for different rates may accompany any indication of disagreement.

d. The contracting officer then submits the request to DOL for approval. The contractor must pay the proposed wage and benefit rate pending response from DOL. When DOL responds to the contracting officer, the contracting officer provides a copy of the response to the contractor with instructions to provide each employee a copy or to post it in the work area (with the applicable WD). The prime contractor must provide a copy of the determination to subcontractor(s), if any, that may employ workers in the conformed classification under the contract. If DOL responds with an approved rate that is higher than the rate proposed by the contractor, the contractor and/or subcontractor(s) must pay such rate retroactive to the start of performance of that classification.

e. DOL's Service Contract Act Conformance Guide provides further guidance on the process.

“”1"”" If the user knows the city where the work will be performed, but needs help in identifying the county in which that city is located, the web sites for the U.S.Geological Survey (USGS) and the National Association of Counties (NACO) provide tools that may be used to identify the county. ““2““ “SCA Health and Welfare (H&W) Rates. On June 1, 1997, DOL initiated a new methodology to determine an appropriate, single SCA H&W benefit rate for SCA Standard WDs. The new, lower rate, listed on the odd-numbered SCA WDs (i.e., 1994-2103, or 1994-2113), was originally established at $1.91 per hour, to be revised in stages over several years (each increase to be published annually on June 1st). DOL continued to publish the SCA Standard WDs, even-numbered (i.e., 1994-2104 or 1994-2114), listing the pre-existing, higher H&W rate of $2.56 per hour until the lower H&W rate reached or exceeded the $2.56 per hour. The old rate listed on the even-numbered Standard WDs continued to be applicable to certain contract actions in accordance with DOL's "All Agency Memorandum #188" published in the Federal Register on December 30, 1996 (page 68647). DOL will continue to increase both Standard WD H&W rates while

completing a study to determine the appropriate application of the new methodology adopted in 1997. Following the guidance in the Users Guide and the "Selecting SCA WDs" on WDOL.gov will assist the user in obtaining the appropriate WD for specific contract actions."

WDOL.gov User's Guide (Ver 6.0) C. Davis Bacon Act: Regulations and Requirements 1. DBA Statute and Regulations The WDOL.GOV Library Page contains a link to DOL's

website and to a copy of the statute (40 U.S.C. 276) and the pertinent DBA regulations (Title 29 CFR Parts 1, 3, 5, and 7).

2. FAR and Supplements. The WDOL.GOV Library Page also contains links to federal

acquisition regulations, including the supplements issued by each federal contracting agency. WDOL.GOV users are urged to familiarize themselves not only with DOL regulations, but also with the pertinent acquisition regulations pertaining to specific contract actions requiring construction work

3. Application of DBA. DBA provisions are applicable to contracts in excess of $2,000 for

the construction, alteration and/or repair, including painting and decorating, of a public building or public work. Coverage is described in detail at Title 29 CFR Part 5 and FAR 22.402 and 22.403.

4. DBA WDs Contracting officers and other interested parties may obtain current, official DBA General Wage Decisions (DBA WDs) from the WDOL.GOV Program.

a. Under the WDOL Program, DOL will publish all DBA WD revisions for a given

week on the WDOL.GOV Program database each Friday. The WDOL.GOV Program will also provide a notice to users of pending revisions to be listed on the next scheduled publishing date (Friday). The pending revisions are found at "DBA WDs to Be Revised Next Friday". The WDOL.GOV Program will also provide a notice to users of pending revisions to be listed on the next scheduled publishing date (Friday). The pending revisions are found at "DBA WDs to Be Revised Next Friday".

b. DOL issues DBA WDs reflecting prevailing wages and benefits paid by the construction industry within specific localities. The DBA WDs are further classified by the nature of the construction projects performed, specifically listed as "schedules": residential, building, highway, and heavy construction. A brief outline of the definitions for each schedule is listed below. Further details and examples may be found in DOL's "All Agency Memorandum No. 130 and 131" issued in 1978 (reference the WDOL Library Page).Building Construction. Includes construction of sheltered enclosures with walk-in access for the purpose of housing persons, machinery, equipment or supplies; all construction of such structures; the installation of utilities and of equipment, both above and below grade levels; as well as incidental grading, utilities and paving. Such structures need not be "habitable" to be building construction. Also, the installation of heavy machinery and/or equipment does not generally change the project's character as a building.

• Building Construction. Includes construction of sheltered enclosures with walk-in access for the purpose of housing persons, machinery, equipment or supplies; all construction of such structures; the installation of utilities and of equipment, both above and below grade levels; as well as incidental grading, utilities and

paving. Such structures need not be "habitable" to be building construction. Also, the installation of heavy machinery and/or equipment does not generally change the project's character as a building.

• Heavy Construction. Includes those projects that are not properly

classified as either "building," "highway," or "residential." Unlike these classifications, heavy construction is not a homogenous classification. Because of this catch-all nature, projects within the heavy classification may sometimes be distinguished on the basis of their particular project characteristics, and separate schedules may be issued for dredging projects, water and sewer line projects, dams, major bridges, and flood control projects.

• Highway Construction. Includes construction, alteration or repair

of roads, streets, highways, runways, taxiways, alleys, trails, paths, parking areas, and other similar projects not incidental to building or heavy construction.

• Residential Construction. Includes the construction, alteration or

repair of single-family houses, apartment buildings of no more than four stories in height. This includes all incidental items such as site work, parking areas, utilities, streets, and sidewalks.

• Some contracts or projects may require more than one general

schedule to be included depending on the nature and extent of the work. This is described in more detail in DOL's All Agency Memo No. 131. The contracting agency should provide designate the work to which each wage determination or part thereof applies per FAR 22.404-2.

c. There may be rare circumstances where the general schedule wage determination

do not contain the principal work classification necessary for contract performance. In those situation a project wage determination may be requested from Department of Labor by submittal of an SF-308 or other request that contains the same information. In such cases the Contracting Officer should follow the instruction in FAR 22.404-3.

d. The contracting officer must monitor the WDOL.GOV Program DBA database

regularly to determine if a selected WD has been revised prior to the expiration of the "effective date" for that particular contract action.

e. DBA WD Numbering System Within WDOL.gov. DBA WDs are generally

numbered by DOL in the following format: a current WD applicable to Virginia is numbered "VA030001" (showing the two-letter state abbreviation (VA), the latest year of publication (03), and the sequential number assigned to the particular WD (0001)). In using the WDOL.gov menus for "Selecting DB WDs" or selecting "Archived DB WDs", the user must use the DBA WD short-number for each WD. The format will be as follows: for VA030001 the short-number is "VA1"; for

MD030114, the short-number is "MD114". In "Selecting DBA WDs, the user may also select a WD without the number by completing the menu for other selection criteria (state, county, type of construction).

f. WDOL.GOV ALERT SYSTEM. To ensure that the contracting officer (or other interested party) is aware of revisions made by DOL to DBA WDs selected for a specific contract action, the WDOL.GOV user may register for automatic email notification of such revisions. Upon selection of an appropriate DBA WD, the user will be offered the opportunity to request email notice of future revisions for a specific period of time, or until a specific date. Contracting officers are encouraged to request this automatic notification process in order to be aware of timely revisions applicable to contract actions.

1. At the Alert Service menu, the user will be asked to provide an email

address for the WDOL.gov to use in providing notification of a revision to a WD. The user may also provide an "alert identifier" which will appear in the WDOL.gov notification and will assist the user in relating the newly revised WD to a specific contract or solicitation, or other area of interest.

2. Users requesting the Alert Service will receive an email notice each time

the selected DBA WD is revised until the Alert Service request expires. CAUTION: The Alert Service does not relieve the contracting officer of the obligation under DBA and its regulations to use timely received new or revised DB WDs in contract actions.

g. Archived DBA WDs.Once DOL revises a DBA WD, the most current revision

will be published on the WDOL.GOV database. Prior revisions, no longer current, will be maintained in the "Archived DBA WD" database for information purposes only. Contracting officers should not use an archived WD in a contract action without prior approval of DOL. Contact DOL at at Telephone no. 866-487-9423.

5. Effective Dates for DBA WD Modifications (Reference Title 29 CFR Part 1, Section 1.6(c) and FAR 22.404-6). a. Modifications to DBA WDs shall be effective if received (or if notice of the

modification is published in the Federal Register or the WD is posted on the WDOL.GOV website): 1. (for contract actions resulting from other than sealed bidding, prior to date

of award; 2. for contracts resulting from sealed bidding, no less than 10 days prior to

bid opening. 6. If you have questions concerning the applicability of DBA provisions or a DBA WD, or

the timeliness of a revised DBA WD, contact the contracting officer or the agency labor advisor.

7. Conformances (Requesting Authorization of Additional Classification and Rate). DOL

issues WDs under DBA using available statistical data on prevailing wages and benefits in a locality. On occasion, the data does not contain sufficient information to issue rates for a particular craft needed in the performance of the contract. Because of this, DBA provisions contain a conformance procedure for the purpose of establishing a DBA-enforceable wage and benefit rate for missing job classifications.

a. Contractors are responsible for determining the appropriate crafts necessary to perform the contract work. If a classification considered necessary for performance of the work is missing from the WD applicable to the contract, the contractor must initiate a request for approval of a proposed wage and benefit rate. Generally, the contractor initiates the request by preparing an SF-1444, Request for Authorization of Additional Classification and Rate, at the time of employment of the unlisted craft. (Reference Title 29 CFR Part 5, Section 5.5(a)(1)(ii) and FAR 22.406-3). The contractor completes blocks 2 through 15 on the form. Requests may be submitted without the form, but must contain the required information.

b. Contractors must request employees, if present, or their designated representative, to sign block 16 noting the employee's concurrence or disagreement with the contractor's proposed wage and benefit rate. A statement supporting a recommendation for different rates may accompany any indication of disagreement. The "designated representative" may be a union representative; however, it cannot be the contractor's representative or personnel officer.

c. The contractor submits the completed SF-1444 to the contracting officer. The contracting officer reviews the form for completeness, and signs the agency's concurrence or disagreement with the contractor's proposal. A statement supporting a recommendation for different rates may accompany any indication of disagreement.

d. The contracting officer then submits the request to DOL for approval. The contractor must pay the proposed wage and benefit rate pending response from DOL. When DOL responds to the contracting officer, the contracting officer provides a copy of the response to the contractor with instructions to provide each employee a copy or to post it in the work area (with the applicable WD). The prime contractor must provide a copy of the determination to subcontractor(s), if any, that may employ workers in the conformed classification under the contract. If DOL responds with an approved rate that is higher than the rate proposed by the contractor, the contractor must pay such rate retroactive to the start of performance of that craft. The contracting officer should request written confirmation from the contractor that this liability has been paid in full.

Section B: How to Interpret General Wage Determinations

This section includes a discussion of how to interpret the information contained in Davis-Bacon General Wage Determinations.

This section includes the answers to several of the most frequently asked questions about administration of the Davis-Bacon and related Acts.

Section A

INTRODUCTION

THE DAVIS-BACON AND RELATED ACTS (DBRA)

The Davis-Bacon Act as amended, requires that each contract over $2,000 to which the United States or the District of Columbia is a party for the construction, alteration, or repair of public buildings or public works shall contain a clause setting forth the minimum wages to be paid to various classes of laborers and mechanics employed under the contract. Under the provisions of the Act, contractors or their subcontractors are to pay workers employed directly upon the site of the work no less than the locally prevailing wages and fringe benefits paid on projects of a similar character. The Davis-Bacon Act directs the Secretary of Labor to determine such local prevailing wage rates.

WAGE DETERMINATIONS

In addition to the Davis-Bacon Act itself, Congress has added prevailing wage provisions to approximately 60 statutes which assist construction projects through grants, loans, loan guarantees, and insurance. These "related Acts" involve construction in such areas as transportation, housing, air and water pollution reduction, and health. If a construction project is funded or assisted under more than one Federal statute, the Davis-Bacon prevailing wage provisions may apply to the project if any of the applicable statutes require payment of Davis-Bacon wage rates.

The geographic scope of the Davis-Bacon Act is limited, by its terms, to the 50 States and the District of Columbia. By the same token, the scope of each of the related Acts is determined by the terms of the particular statute under which the Federal assistance is provided. For example, Davis-Bacon prevailing wage provisions would apply to a construction contract located in Guam or the Virgin Islands funded under the Housing and Community Development Act of 1974, even though the Davis-Bacon Act itself does not apply to Federal construction contracts to be performed outside the 50 States and the District of Columbia.

A "wage determination" is the listing of wage rates and fringe benefit rates for each classification of laborers and mechanics which the Administrator of the Wage and Hour Division of the U.S. Department of Labor has determined to be prevailing in a given area for a particular type of construction (e.g., building, heavy, highway, or residential).

The Wage and Hour Division issues two types of wage determinations: general determinations, also known as area determinations, and project determinations. The term "wage determination" is defined as including not only the original decision but any subsequent decisions modifying, superseding, correcting, or otherwise changing the rates and scope of the original decision.

General wage determinations reflects those rates determined by the Division to be prevailing in a specific geographic area for the type of construction described. General wage decisions and modifications and supersedeas decisions thereto, contain no expiration dates and are effective from their date of notice in the Federal Register, or on the date written notice is received by the agency, whichever is earlier. If a contracting agency has a proposed construction project to which a general determination would be applicable, the published determination may be used by the contracting agency without consulting the Department of Labor, provided that questions concerning its use shall be referred to the Department of Labor.

Project wage determinations are issued at the specific request of a contracting agency; each is applicable to the named project only; and expires 180 calendar days from the date of issuance unless an extension of the expiration date is requested by the agency and approved by the Wage and Hour Division. If such a determination is not used in the period of its effectiveness, it is void. Project determinations are issued in response to contracting agencies submitting to the Wage and Hour Division a Standard Form 308 requesting a wage determination.



Extensions of Wage Determinations

Modifications of general and project wage determinations are issued to update data in the original determination. Where a contract will be entered pursuant to competitive bidding procedures, a modification, notice of which is published in the Federal Register less than 10 days before the opening of bids shall be effective unless the agency finds that there is not a reasonable time still available before bid opening to notify bidders of the modification and a report of the finding is inserted in the contract file. (For projects assisted under the National Housing Act, and for projects to receive housing assistance payments under section 8 of the U.S. Housing Act of 1937, dates other than bid opening apply. See Regulations, 29 CFR Part 1, section 1.6). If the contracting officer chooses to disregard a modification, a report of this action shall be inserted in the contract file and made available to the Wage and Hour Division upon request.

If a contract has not been awarded within 90 days after bid opening, modifications prior to award to a general wage determination in the contract shall be effective with respect to that contract unless the agency requests and obtains an extension of the 90-day period from the Wage and Hour Division.

Supersedeas Wage Determinations are issued annually to replace general decisions issued in the previous edition of the publication entitled General Wage Determinations Issued Under the Davis-Bacon and Related Acts. Supersedeas project wage determinations may also be issued. Supersedeas decisions affecting determinations are effective under the same circumstances as "modifications." Whereas a modification to a wage determination may make changes in only selected provisions of the wage determination, a supersedeas determination replaces the entire existing wage decision.

Notice is published in the Federal Register each week (usually on Friday) to advise the public of the publication of general wage determinations, modifications, supersedeas actions, withdrawal actions, and corrections affecting such wage determinations.

When a general wage determination has not been awarded within 90 days after bid opening, the head of the contracting/assisting agency may request an extension of the 90 day period from the Wage and Hour Administrator. When, due to unavoidable circumstances, a project wage determination expires before award but after bid opening, the head of the contracting/assisting agency may request an extension of the expiration date of the project wage determination in the bid specifications instead of issuing a new wage determination. (For projects assisted under the National Housing Act, and for projects to receive housing assistance payment under section 8 of the U.S. Housing Act of 1937, dates other than bid opening apply. See Regulations 29CFR, Part 1, section 1.6.)

Extension requests should be supported by a written finding including a brief statement of the factual support, that extension of the expiration date of the determination is necessary and proper in the public interest to prevent injustice or undue hardship or to avoid serious impairment in the conduct of Government business.



Section B

How to Interpret General Wage Determinations

The Administrator will either grant or deny the request for an extension after consideration of all the circumstances, including an examination to determine if the previously issued rates remain prevailing. If a request for the extension of a project wage determination is denied, a new wage determination will be issued to replace an expired project wage determination.

TopA. WAGE DETERMINATIONS ARE STRUCTURED ACCORDING TO THE

FOLLOWING FORMAT:

Each wage determination begins with a cover sheet that defines its applicability. Included on this sheet are:

The decision number.

The number of the decision superseded, if applicable.

State(s) covered.

Type of construction (building, heavy, highway, and/or residential).

County(ies) or city(ies) covered.

Description of the construction to which the wage determination applies and/or construction excluded from its application.

Record of modifications, including the initial publication date, modification numbers and dates.

In the body of each wage determination is the listing of classifications (laborers and mechanics) and accompanying basic hourly wage rates and fringe benefit rates that have been determined to be prevailing for the specified type(s) of construction in the geographic area(s) covered by the wage determination. Classification listings may also include classification groupings, fringe benefit footnotes, descriptions of the geographic areas to which subclassifications and different wage rates apply, and/or certain classification definitions. (See below for how to know the source of a rate.)

In wage determination modifications, an asterisk ("*") is used to indicate that the item marked is changed by that modification.

The wage determination appeals process is explained at the end of the wage determination. The explanation includes a description of the criteria for appeal and



where to file the appeal.

The last page of each wage determination ends with "END OF DECISION"centered above the last page number for the determination. Users can refer to the page number at the bottom of that page to check back to be sure that they have all the preceding pages of the determination.

B. HOW TO FIND THE WAGE RATE FOR A PARTICULARCLASSIFICATION AND UNDERSTAND THE BASIS FOR THE WAGERATE:

Review the wage determination in light of the following information:

1. The body of each wage determination lists the classifications and wagerates that have been found prevailing for the cited type(s) of constructionin the area covered by the wage determination.

The classifications are listed in alphabetical order of "identifiers" thatindicate whether particular rates are union or non-union rates.

Many wage determinations contain only non-union wage rates, somecontain only union-negotiated wage rates, and others contain both unionand non-union wage rates that have been found prevailing in the area forthe type of construction covered by the wage determination.

2. Above each classification (or group of classifications) listed, analphanumeric "identifier" and date provide information about the source ofthe classification(s) and wage rate(s) listed for it. (SU means the rateslisted under that identifier were derived from survey data and are notunion rates, although the survey data on which they are based may includeboth union and non-union data.)

a. The identifier is SUAR0037A. SU indicates rates that are not unionrates; AR = Arkansas; 0037A is a sequential number and characterused in producing the wage determination. Dates before 1993 thatappear with such "SU" identifiers were generated in producing thewage determinations and are not meaningful to users. However, a1993 or later date will indicate that the classification(s) and wagerate(s) under that identifier were issued in the general wagedetermination on that date and reflect the results of a survey.

b. Any identifier beginning with characters other than SU is usedwhere union classification(s) and wage rate(s) have been foundprevailing.

In each such identifier, the first four letters indicate theinternational union (see listing, below) for the local union thatnegotiated the wage rates listed under that identifier. Then, there isa four-digit number that indicates the local union number. For



example, the identifier is ELEV0101A. ELEV = Elevator Constructors; 0101 = the local union number (district council number where applicable); and "A" = a character used internally in processing the wage determination. The date shown is the effective date of the most current negotiated rate entered into the automated system that generates general wage determinations.

Special identifiers are necessary for two trades because the samelocal union number(s) is accompanied by different wage rates indifferent states. Bricklayers local union numbers are not uniquenationwide, but are unique within each State. Similarly, SprinklerFitters Local Union No. 669 has negotiated different wage rates ineach State within its territorial jurisdiction. Therefore, the identifiersfor the Bricklayers unions are in the format "BR + stateabbreviation," (referenced below as BRXX), and the identifier "SF+ state abbreviation" is used for Sprinkler Fitter Local No. 669'srates.

It is common for many local unions to negotiate wage rates formore than one classification. Where this is done, all theclassifications for which that union's wage rates are determined tobe prevailing will appear under the identifier for that union.

For example, the same union may negotiate wage and fringebenefits for painters and glaziers. In such a case, the wage rate forthe glazier, as well as that for the painter will be found under aclassifier beginning with "PAIN." Similarly, users may need to lookunder an identifier beginning with "CARP" to find not only rates forcarpenters, but also those for millwrights, piledrivermen and(marine) divers.

3. Following are the identifier codes used to reference the various craftunions. Examples of classifications for which their local unions commonlynegotiate wage and fringe benefit rates are shown in parentheses.

ASBE = International Association of Heat and Frost Insulators and Asbestos Workers

BOIL = International Brotherhood of Boiler Makers, Iron Shipbuilders, Blacksmiths, Forgers and Helpers

BRXX = International Union of Bricklayers, and Allied Craftsmen

(bricklayers, cement masons, stone masons, tile, marble and terrazzo workers)

CARP = United Brotherhood of Carpenters and Joiners of America



(carpenter, millwright, piledrivermen, soft floor layers, divers)

ELEC = International Brotherhood of Electrical Workers

(electricians, communication systems installers, and other low voltage specialty workers)

ELEV = International Union of Elevator Constructors

ENGI = International Union of Operating Engineers

(operators of various types of power equipment)

IRON = International Association of Bridge, Structural and Ornamental Iron Workers

LABO = Laborers' International Union of North America

PAIN = International Brotherhood of Painters and Allied Trades

(painters, drywall finishers, glaziers, soft floor layers)

PLAS = Operative Plasterers' and Cement Masons' International Association of the United States and Canada

(cement masons, plasterers)

PLUM = United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada

(plumbers, pipefitters, steamfitters, sprinkler fitters)

ROOF = United Union of Roofers, Waterproofers and Allied Workers

SHEE = Sheet Metal Workers International Association

SU.... = As discussed above, the "SU..." identifier is for rates derived from survey data where the union rate(s) were not determined to be prevailing for the classification



(s) listed. (The data reported for such a classificationand used in computing the prevailing rate may haveincluded both union and non-union wage data.) Notethat various classifications, for which non-union rateshave been determined to be prevailing, may be listedin alphabetical order under this identifier, which thecomputer places into the wage determination inalphabetical order, as listed here.

TEAM = International Brotherhood of Teamsters

Section C

Questions and Answers on the use of Davis-Bacon

Wage DeterminationsTop

Question. How do I obtain a wage determination for a construction project to be performed at a location not covered by a published determination?

Answer. If no general wage determination is listed for a given county and type of construction, the following procedure to obtain a project wage determination should be followed.

The Federal agency funding or financially assisting the construction project requests a wage determination under the Davis-Bacon Act or any of the related prevailing wage statutes by submitting a Standard Form (SF) 308 to the following address:

U.S. Department of LaborEmployment Standards AdministrationWage and Hour DivisionBranch of Construction Wage Determinations200 Constitution Avenue, N.W., Room S-3014Washington, D.C. 20210

In completing a SF-308, the agency must furnish:

(1) A sufficiently detailed description of the project toindicate the type(s) of construction involved. Separateattachments, if necessary for identification of the typeof project, must be furnished.

(2) The county (or other civil subdivision) and State inwhich the proposed project is located. The timerequired for processing requests for wagedeterminations varies according to the facts andcircumstances in each case. An agency should



anticipate that such processing will take at least 30 days.

Question. The wage determination applicable to my project does not contain a class of workers which is needed to complete construction. Can other worker classification(s) and wage rate(s) be approved for use on the project?

Answer. Prior to bid opening, if the only classification that will perform work on a contract is not listed on a general wage determination for the type of construction in the area, the contracting/assisting agency may submit a SF-308 request for a project wage determination for application to that project. In order to assure special treatment of a request where this circumstance exists, a note explaining the special circumstances should be made in the project description block of the SF-308. (A similar note may be made on a SF-308 request for a project wage determination, where a general wage determination is not applicable, and all of the work on the project will be performed by a particular classification, as a means to assure that a wage rate for that classification will be issued for the project).

Example: An upcoming contract calls for repainting all the residences at a military base, and there is no painter classification in the general wage schedule issued for application to residential construction in the county where the project is located. A SF-308 may be submitted by the agency for application to that contract, and a project wage determination will be issued with a painter classification and wage rate for use prior to bid opening (or the other applicable date where certain assistance programs of the Department of Housing and Urban Development (HUD) are the basis for coverage under the Davis-Bacon and related Acts). If there is no general wage determination issued for that area and type of construction, the same procedure should be followed.

After contract award, if the contract wage determination does not contain a class of workers that is needed to complete the construction, a contractor shall submit to the contracting officer a request for the addition of the needed classification(s) of laborers or mechanics not listed in the wage determination, together with proposed wage rates and fringe benefits conformable to the wage determination.

The contracting officer shall require that any class of laborers or mechanics which is not listed in the wage determination and which is to be employed under the contract be classified in conformance with the wage determination. An additional classification action, even if undisputed, is not valid unless the Department of Labor has approved it. If a dispute exists, the matter must be referred to the Wage and Hour Division for resolution, together with the views of all interested parties and the recommendation of the contracting officer. Approval of the additional classification and the proposed wage rate and fringe benefits requires that the following criteria have been met:



(1) The work to be performed by the classification requested is not performed by any classification in the wage determination; and

(2) The classification is utilized in the area by the construction industry; and

(3) The proposed wage rate, including any bona fide fringe benefits, bears a reasonable relationship to the wage rates contained in the wage determination; and

(4) There is evidence of agreement on the classification and proposed wage rate among the parties involved, or the views of those involved -- the contractor(s), employees (if known) or their representative, and the contracting officer/agency -- are forwarded for consideration to the Wage and Hour Division; and

(5) The request does not involve wage rates for apprentices or trainees.

All conformance notices should be responded to in writing within 30 days of receipt. These responses either approve or deny the request or inform the submitting agency that additional time will be required. Failure to receive a response does not constitute approval. If a response is not received, the Wage and Hour Division should be contacted directly. Every conformance request is analyzed to verify that the criteria for approval are met.

Any interested person requesting reconsideration of a conformance should present their request in writing accompanied by supporting data or other pertinent information to the Wage and Hour Division. The Wage and Hour Division should respond within 30 days or notify the requestor within this time frame that additional time is needed.

If reconsideration of a conformance action has been sought and denied, an appeal for review may be filed with the Administrative Review Board. (See 29 CFR 1.8 and 1.9, and 29 CFR Part 7).

Question. How do workers on a construction site know that a project is covered by the Davis-Bacon Act? How do they know the prevailing wage to which they are entitled?

Answer. The wage determination (including any additional classifications and wage rates conformed) and a Davis-Bacon poster (WH-1321) must be posted at all times by the contractor and its subcontractors at the site of the work in a prominent and accessible place where it can be easily seen. The WH-1321 poster may be obtained at no charge from offices of the Wage and Hour Division. In the absence of such posted information, any person who wants



to determine if the project is covered should contact the federal agency funding or assisting the project or the Wage and Hour Division. Multi-year construction contracts that contain option provisions by which a contracting agency may unilaterally extend the term of the contract require inclusion of a current wage determination at the time the option is exercised. (In contrast, in situations where a contractor is given additional time to complete original contract commitments, the wage determination in that contract applies).

Question: Once construction has begun, are the workers' wage rates affected when the wage determination for the area in which the project is located is changed?

Answer. As a general rule, the wage determination incorporated into a bid solicitation and related contract award establishes the minimum wage rates and fringe benefits which must be paid for the entire term of the contract.

Where the proper wage determination is incorporated into a contract prior to award of the contract, wage determination modifications issued after bid opening are not applicable to the contract -- except in the case of a general wage determination in a contract that has not been awarded within 90 days after the bid opening and an extension of the 90-day limit has not been granted. (Specific requirements involving dates other than bid opening apply for projects assisted under the National Housing Act and for projects that receive housing assistance payments under section 8 of the U.S. Housing Act of 1937).

Upon his or her own initiative or at the request of an agency, the Administrator may correct any wage determination if he or she finds that the determination contains an inadvertent clerical error. For example, a wage determination contains a wage rate where there is a transposition ofnumbers, such as a fringe benefit of $2.53 appears in the wage determination as $2.35.

Also, the Administrator may issue a wage determination after contract award or after the beginning of construction if:

(a) the contracting/assisting Federal agency has failed to incorporate the applicable wage determination in a contract required to contain prevailing wage rates determined in accordance with the Davis-Bacon Act, or has used a wage determination which by its terms or the provisions of Regulations, 29 CFR Part 1, clearly does not apply to the contract, or

(b) the wrong wage determination has been incorporated in the contract because of an inaccurate description of the project or its location in the agency's SF-308 request.

Under either of these two circumstances, the agency shall either



terminate and resolicit the contract with the valid wage determination, or incorporate the valid wage determination retroactive to the beginning of construction through supplemental agreement or through change order, provided that the contractor is compensated for any increases in wages resulting from such change. The method of incorporation of the valid wage determination, and adjustment in contract price, where appropriate, should be in accordance with applicable procurement law.

Question. Is it possible for more than one wage schedule to apply to specifications for a particular contract?

Answer. Construction projects are generally classified as either Building, Heavy, Highway or Residential for purposes of issuing wage determinations. Wage schedules for one or more of these construction categories may have application to construction items contained in a proposed construction project. Guidelines for the selection of proper wage schedules are set forth in All Agency Memoranda Nos. 130 (March 17, 1978) and 131 (July 14, 1978). Any questions regarding the application of these guidelines to a particular project, or any disputes regarding the application of the wage schedules issued for the various construction categories are to be referred to the Wage and Hour Division, together with relevant information, including a complete description of the project and area practice.

Question. As the contracting officer/Federal agency representative, what is my obligation when the wage determination(s) applicable to a construction project contains multiple wage schedules (for different counties and/or types of construction?

Answer. It is the responsibility of the contracting officer/Federal agency representative to advise contractors which schedule of prevailing wages shall be applied to the various construction items in the bid specifications. Because of the complexities in the application of multiple schedules, the contracting officer should consult with the Wage and Hour Division to resolve any questions.

Question. Can apprentices, trainees, and/or helpers work on a project covered by the Davis-Bacon or related Acts (DBRA), and what wage rates must they be paid?

Answer. Individuals who meet the following definition may be employed as apprentices on DBRA projects:

(a) A person employed and individually registered in a bona fide apprenticeship program registered with the U.S. Department of Labor, Employment and Training Administration, Bureau of Apprenticeship and Training, or with a State Apprenticeship Agency recognized by the Bureau,

or



(b) A person in the first 90 days of probationary employment as an apprentice in such an apprenticeship program, who is not individually registered in the program, but who has been properly certified to be eligible for probationary employment as an apprentice.

Trainees employed must be persons registered in a construction occupation under a program which has been approved in advance by the U.S. Department of Labor, Employment and Training Administration, as meeting its standards for on-the-job training programs and which have been so certified by that Administration.

Information on wage rates paid to apprentices and trainees is not reflected in Davis-Bacon wage determinations. Similarly, their addition through the additional classification procedure (conformance) is neither necessary nor appropriate. On projects funded by the Federal-Aid Highway Act, apprentices and trainees certified by the Secretary of Transportation are not covered by Davis-Bacon labor standards.

The proper wage rates to be paid to apprentices and trainees are those specified by the particular programs in which they are enrolled, expressed as a percentage of the journeyman rate on the wage determination. In the event employees reported as apprentices or trainees on a covered project have not been properly registered within the meaning of the Regulations and the contract stipulations, or are utilized at the job site in excess of the ratio to journeymen permitted under the approved program, they must be paid the applicable wage rates for laborers and mechanics employed on the project performing in the classification of work they actually performed. This applies regardless of work classifications which may be listed on the submitted payrolls and regardless of their level of skill.

Helper classifications may be issued in or added to a wage determination only where the (a) the duties of the helpers are clearly defined and distinct from those of the journeyman classification and from the laborer, (b) the use of such helpers is an established prevailing practice in the area, and (c) the term "helper" is not synonymous with "trainee" in an informal training program.

Question. What wage rates must be paid to supervisory employees (foremen, superintendents, etc.) employed on a covered project?

Answer. The wage rates for bona fide supervisory employees are not regulated under the Davis-Bacon and related Acts because their duties are primarily administrative or executive in nature rather than those of laborers or mechanics. However, such employees who devote more than 20 percent of their time during a workweek to mechanic or laborer duties are laborers and mechanics for the time so spent, and must be paid at least the appropriate wage rates specified in the wage determination. Employees



who are bona fide executive, administrative, or professional employees as defined under the Fair Labor Standards Act at 29 CFR Part 541 are not covered by the Davis-Bacon Act.

Question. If it is believed that the rates on a wage determination do not accurately reflect those prevailing in the area, how may the wage determination be appealed?

Answer. Any interested person requesting reconsideration of a wage determination or of a ruling regarding application of a wage determination to a specific construction project should present their request in writing accompanied by supporting data or other pertinent information to the Wage and Hour Division. The Wage and Hour Division should respond within 30 days or notify the requestor within this time frame that additional time is needed.

An "interested person" is considered to include, without limitation:

(1) Any contractor, or an association representing a contractor, who is likely to seek or to work under a contract containing a particular wage determination, or any laborer or mechanic, or any labor organization which represents a laborer or mechanic, who is likely to be employed or to seek employment under a contract containing a particular wage determination, and,

(2) Any Federal, State, or local agency concerned with the administration of a proposed contract or contract containing a particular wage determination issued pursuant to the Davis-Bacon Act or any of its related statutes.

If reconsideration of a wage determination has been sought and denied, an appeal for review of the wage determination or its application may be filed with the Administrative Review Board, U.S. Department of Labor, Room N-1651, 200 Constitution Avenue, N.W., Washington, D.C. 20210. Requests for review of wage determinations must be filed, and any new wage determination resulting from the appeal must be issued, before contract award or start of construction where there is no award (or under the National Housing Act, before the date of initial endorsement, or the beginning of construction, whichever occurs first; or under Section 8 of the U.S. Housing Act of 1937, before the date of the housing assistance payments agreement, or the beginning of construction, whichever occurs first).

The Wage Appeals Board (now the Administrative Review Board) was established by the Secretary of Labor in 1963 to decide, at its discretion, appeals concerning questions of fact and law related to final decisions of the Wage and Hour Division concerning:

Controversies over the payment of prevailing wage rates, overtime pay, or proper classifications;



Wage determinations issued under the Davis-Bacon and related Acts;

Debarment cases arising under 29 CFR Part 5;

Cases involving the assessment of liquidated damages under the Contract Work Hours and Safety Standards Act;

Appeal of any other final decision under 29 CFR Parts 1, 3, or 5.

The Administrative Review Board consists of three members, one of whom is designated chairman. The members are appointed by the Secretary of Labor and majority vote of the Administrative Review Board is necessary for a decision, except that a decision to hear any appeal may be made by one member. The Board can act as fully and finally as the Secretary of Labor concerning the matters within its jurisdiction. The rules prescribed in 29 CFR, Part 7, "Practice Before Wage Appeals Board", govern the proceedings of the Board.

If this contract is covered by the EO, the contractor must provide employees with 1 hour of paid sick leave for every 30 hours they work, up to 56 hours of paid sick leave each year. Employees must be permitted to use paid sick leave for their own illness, injury or other health-related needs, including preventive care; to assist a family member (or person who is like family to the employee) who is ill, injured, or has other health-related needs, including preventive care; or for reasons resulting from, or to assist a family member (or person who is like family to the employee) who is a victim of, domestic violence, sexual assault, or stalking. Additional information on contractor requirements and worker protections under the EO is available at www.dol.gov/whd/govcontracts. Unlisted classifications needed for work not included within the scope of the classifications listed may be added after award only as provided in the labor standards contract clauses (29CFR 5.5 (a) (1) (ii)). ----------------------------------------------------------------

The body of each wage determination lists the classification and wage rates that have been found to be prevailing for the cited type(s) of construction in the area covered by the wage determination. The classifications are listed in alphabetical order of "identifiers" that indicate whether the particular rate is a union rate (current union negotiated rate for local), a survey rate (weighted average rate) or a union average rate (weighted union average rate). Union Rate Identifiers A four letter classification abbreviation identifier enclosed in dotted lines beginning with characters other than "SU" or "UAVG" denotes that the union classification and rate were prevailing for that classification in the survey. Example: PLUM0198-005 07/01/2014. PLUM is an abbreviation identifier of the union which prevailed in the survey for this classification, which in this example would be Plumbers. 0198 indicates the local union number or district council number where applicable, i.e., Plumbers Local 0198. The next number, 005 in the example, is an internal number used in processing the wage determination. 07/01/2014 is the effective date of the most current negotiated rate, which in this example is July 1, 2014. Union prevailing wage rates are updated to reflect all rate changes in the collective bargaining agreement (CBA) governing this classification and rate. Survey Rate Identifiers Classifications listed under the "SU" identifier indicate that no one rate prevailed for this classification in the survey and the published rate is derived by computing a weighted average rate based on all the rates reported in the survey for that classification. As this weighted average rate includes all rates reported in the survey, it may include both union and non-union rates. Example: SULA2012-007 5/13/2014. SU indicates the rates are survey rates based on a weighted average calculation of rates and are not majority rates. LA indicates the State of Louisiana. 2012 is the year of survey on which these classifications and rates are based. The next number, 007 in the example, is an internal number used in producing the wage determination. 5/13/2014 indicates the survey completion date for the classifications and rates under that identifier. Survey wage rates are not updated and remain in effect until a new survey is conducted. Union Average Rate Identifiers Classification(s) listed under the UAVG identifier indicate that no single majority rate prevailed for those classifications; however, 100% of the data reported for the classifications was union data. EXAMPLE: UAVG-OH-0010 08/29/2014. UAVG indicates that the rate is a weighted union average rate. OH indicates the state. The next number, 0010 in

the example, is an internal number used in producing the wage determination. 08/29/2014 indicates the survey completion date for the classifications and rates under that identifier. A UAVG rate will be updated once a year, usually in January of each year, to reflect a weighted average of the current negotiated/CBA rate of the union locals from which the rate is based. ---------------------------------------------------------------- WAGE DETERMINATION APPEALS PROCESS 1.) Has there been an initial decision in the matter? This can be: * an existing published wage determination * a survey underlying a wage determination * a Wage and Hour Division letter setting forth a position on a wage determination matter * a conformance (additional classification and rate) ruling On survey related matters, initial contact, including requests for summaries of surveys, should be with the Wage and Hour Regional Office for the area in which the survey was conducted because those Regional Offices have responsibility for the Davis-Bacon survey program. If the response from this initial contact is not satisfactory, then the process described in 2.) and 3.) should be followed. With regard to any other matter not yet ripe for the formal process described here, initial contact should be with the Branch of Construction Wage Determinations. Write to: Branch of Construction Wage Determinations Wage and Hour Division U.S. Department of Labor 200 Constitution Avenue, N.W. Washington, DC 20210 2.) If the answer to the question in 1.) is yes, then an interested party (those affected by the action) can request review and reconsideration from the Wage and Hour Administrator (See 29 CFR Part 1.8 and 29 CFR Part 7). Write to: Wage and Hour Administrator U.S. Department of Labor 200 Constitution Avenue, N.W. Washington, DC 20210 The request should be accompanied by a full statement of the interested party's position and by any information (wage payment data, project description, area practice material, etc.) that the requestor considers relevant to the issue.

3.) If the decision of the Administrator is not favorable, an interested party may appeal directly to the Administrative Review Board (formerly the Wage Appeals Board). Write to: Administrative Review Board U.S. Department of Labor 200 Constitution Avenue, N.W. Washington, DC 20210 4.)

If this contract is covered by the EO, the contractor must provide employees with 1 hour of paid sick leave for every 30 hours they work, up to 56 hours of paid sick leave each year. Employees must be permitted to use paid sick leave for their own illness, injury or other health-related needs, including preventive care; to assist a family member (or person who is like family to the employee) who is ill, injured, or has other health-related needs, including preventive care; or for reasons resulting from, or to assist a family member (or person who is like family to the employee) who is a victim of, domestic violence, sexual assault, or stalking. Additional information on contractor requirements and worker protections under the EO is available at www.dol.gov/whd/govcontracts.

Unlisted classifications needed for work not included within the scope of the classifications listed may be added after award only as provided in the labor standards contract clauses (29CFR 5.5 (a) (1) (ii)). ---------------------------------------------------------------- The body of each wage determination lists the classification and wage rates that have been found to be prevailing for the cited type(s) of construction in the area covered by the wage determination. The classifications are listed in alphabetical order of "identifiers" that indicate whether the particular rate is a union rate (current union negotiated rate for local), a survey rate (weighted average rate) or a union average rate (weighted union average rate). Union Rate Identifiers A four letter classification abbreviation identifier enclosed in dotted lines beginning with characters other than "SU" or "UAVG" denotes that the union classification and rate were prevailing for that classification in the survey. Example: PLUM0198-005 07/01/2014. PLUM is an abbreviation identifier of the union which prevailed in the survey for this classification, which in this example would be Plumbers. 0198 indicates the local union number or district council number where applicable, i.e., Plumbers Local 0198. The next number, 005 in the example, is an internal number used in processing the wage determination. 07/01/2014 is the effective date of the most current negotiated rate, which in this example is July 1, 2014. Union prevailing wage rates are updated to reflect all rate changes in the collective bargaining agreement (CBA) governing this classification and rate. Survey Rate Identifiers Classifications listed under the "SU" identifier indicate that no one rate prevailed for this classification in the survey and the published rate is derived by computing a weighted average rate based on all the rates reported in the survey for that classification. As this weighted average rate includes all rates reported in the survey, it may include both union and non-union rates. Example: SULA2012-007 5/13/2014. SU indicates the rates are survey rates based on a weighted average calculation of rates and are not majority rates. LA indicates the State of Louisiana. 2012 is the year of survey on which these classifications and rates are based. The next number, 007 in the example, is an internal number used in producing the wage determination. 5/13/2014 indicates the survey completion date for the classifications and rates under that identifier. Survey wage rates are not updated and remain in effect until a new survey is conducted.

Union Average Rate Identifiers Classification(s) listed under the UAVG identifier indicate that no single majority rate prevailed for those classifications; however, 100% of the data reported for the classifications was union data. EXAMPLE: UAVG-OH-0010 08/29/2014. UAVG indicates that the rate is a weighted union average rate. OH indicates the state. The next number, 0010 in the example, is an internal number used in producing the wage determination. 08/29/2014 indicates the survey completion date for the classifications and rates under that identifier. A UAVG rate will be updated once a year, usually in January of each year, to reflect a weighted average of the current negotiated/CBA rate of the union locals from which the rate is based. ---------------------------------------------------------------- WAGE DETERMINATION APPEALS PROCESS 1.) Has there been an initial decision in the matter? This can be: * an existing published wage determination * a survey underlying a wage determination * a Wage and Hour Division letter setting forth a position on a wage determination matter * a conformance (additional classification and rate) ruling On survey related matters, initial contact, including requests for summaries of surveys, should be with the Wage and Hour Regional Office for the area in which the survey was conducted because those Regional Offices have responsibility for the Davis-Bacon survey program. If the response from this initial contact is not satisfactory, then the process described in 2.) and 3.) should be followed. With regard to any other matter not yet ripe for the formal process described here, initial contact should be with the Branch of Construction Wage Determinations. Write to: Branch of Construction Wage Determinations Wage and Hour Division U.S. Department of Labor 200 Constitution Avenue, N.W. Washington, DC 20210 2.) If the answer to the question in 1.) is yes, then an interested party (those affected by the action) can request review and reconsideration from the Wage and Hour Administrator (See 29 CFR Part 1.8 and 29 CFR Part 7). Write to: Wage and Hour Administrator

U.S. Department of Labor 200 Constitution Avenue, N.W. Washington, DC 20210 The request should be accompanied by a full statement of the interested party's position and by any information (wage payment data, project description, area practice material, etc.) that the requestor considers relevant to the issue. 3.) If the decision of the Administrator is not favorable, an interested party may appeal directly to the Administrative Review Board (formerly the Wage Appeals Board). Write to: Administrative Review Board U.S. Department of Labor 200 Constitution Avenue, N.W. Washington, DC 20210 4.) All decisions by the Administrative Review Board are final. ================================================================ END OF GENERAL DECISION
