Bidder Questions � Question

All excavation on this project needs to be removed and disposed off-site. The May 18, 2006 Geotechnical report has documented the existence of gypsum waste throughout the site and to various depths. Based on this report, it is clear that all of the excavated material will consist of gypsum waste material along with some crushed concrete that is mixed in the upper 18" of the site. The gypsum waste cannot be "source separated" in order to allow for a recycling option. The test pits also revealed a strong odor (hydrogen sulfide gas), which is typical of gypsum waste. The off-site disposal of such a large volume of gypsum waste presents a challenge to the bidders for several reasons: (a) the analytical data presented in the report may not be accepted by disposal facilities for actual disposal facility acceptance purposes; (b) the bid documents do not address the protocols and procedures that will be required of the Contractor in order to dispose of the gypsum waste; (c) more analytical testing will likely need to be performed by the Contractor but the bid proposal does not provide separate payment for these tests; (d) the bid documents have not characterized the gypsum waste for disposal purposes or for bidding purposes; (e) the bid proposal does not have a separate unit price pay item to pay per ton for the off-site disposal of the gypsum waste, which is customary practice when disposing of solid waste; (f) the project completion time of 90 days is not sufficient for the Contractor to perform additional testing and to obtain disposal facility acceptance; and, (g) as the generator of the waste, it is the responsibility of the owner to ensure that the gypsum waste is properly disposed, yet the bid documents do not address this important aspect of the project. Please clarify and address these items in an addendum as soon as possible.

□ Response

a. The Proposal Form has been modified to include a Lump Sum Add Alternate (AA-2) for

additional laboratory testing required to facilitate the Disposal of Soils Containing Gypsum Waste, All work associated with sampling and testing shall be arranged/performed by the Contractor, but will be paid for by the Owner under the Bid item AA-2

� Question

We received and reviewed Addendum #1 for the above referenced project and wish to point out the following items that require further clarification. a. The Addendum Q&A'S did not provide a Response that addresses the issues with the

completion time. Please address this important issue as soon as possible. b. The Response to the Question pertaining to the lack of details for the Trench Drain needs

further clarification. Please add the following details to the bidding documents � Please provide a typical cross section through the Trench Drain indicating the type and

thickness of any stone bedding, and indicate if any concrete encasement is required. � Also, please provide a detail for joining the 12" storm drain pipe with the trench drain.

c. The Addendum #1 drawings did not provide "clouds" or other symbols to indicate what was changed on the new drawings, which is customary practice when making revisions to drawings. The lack of "clouded" revisions makes it very difficult to find the revisions. Therefore, we request that all revisions be "clouded" so that the changed information can be readily identified. For example we cannot determine what was changed on the following drawings: Dwg C-3, C-6, C-8 & C-15.

□ Response

a. Refer to the response above for information responding to the issues with the completion

time.

b. Follow the manufacturer’s recommendations for bedding and construction of the pipe to drain connection. Contractor shall submit Shop Drawings to Owner for approval prior to ordering materials.

c. Descriptions of changes for C Drawings were included as text with the Addendum, with no clouds shown. The Drawings have not been approved by DNREC as of this writing. Therefore, clouds cannot be shown.


� Question

Federal wage rates were not included in Addendum #1.

□ Response

The Federal Wage Rate Schedule is included in Attachment B to this Addendum No. 2. � Question

… there are several questions that were asked at the pre-bid meeting that were to be answered in addendum #1, however they were not. Will there be another addendum with answers to the pre-bid meeting questions? Specifically the questions are regarding;

1. The inclusion of the Federal rate schedule 2. The Earthwork specification references to Unforeseen conditions and Unsuitable

Excavated Materials 3. The type of paint to be used for line striping

□ Response

1. The Federal Wage Rate Schedule is included in Attachment B to this Addendum No. 2. 2. As indicated in the response to the first question above, for the purposes of the Bidder’s

development of a cost for Bid Item LS-4, Bulk Excavation and Grading, Bidder shall assume that all materials excavated down to the specified subgrade shall be removed off-site with no “Special Disposal Requirements” (i.e., Hazardous Waste or Special Solid Waste). If Soils Containing Gypsum Waste are encountered, disposal of the materials will be dealt with as described above.

With respect to Unsuitable Excavated Materials beyond the limits of the specified subgrade, the Bid Form has been revised to include a Bid Item (UP-1) for the undercut and backfill of unsuitable soils. For the purposes of the Bidder’s development of a cost for Bid Item UP-1. Undercut and Backfill of Unsuitable Soils, Bidder shall assume the following:

Undercut and Backfill of Unsuitable Soils includes: - Excavation of the unsuitable soils;


- Offsite disposal of the excavated materials without “Special Disposal Requirements”;

- Lining of the excavation with a geotextile filter fabric; and - Backfill with No. 57 Stone.

If the excavated soils are determined to be Soils Containing Gypsum Waste, the disposal of the materials will be paid for in accordance with UP-2 described above.

3. Refer to revised Specification Section 3210150, “Pavement Markings” included in Attachment D to this Addendum No. 2

� Question

Based on the information contained in the Geotechnical Report the material to be excavated from the New Chiquita Chassis Yard contains gypsum waste intermingled with crushed concrete. Based on a conversation with the Cherry Island Landfill the excavated material from the New Chiquita Chassis Yard will be regarded as a Special Waste and the tipping fee would be $88.50 per ton. The excavated material cannot be accepted as cover soil without a lengthy review and approval period that would require the submittal of analytical data. We were also informed that the review period for cover soil approval would take several months to complete, at best.

We were also referred to the attached waste disposal guidance document that generators of solid waste need to follow in order to obtain disposal facility acceptance for Special Waste. The generator of special waste needs to provide analytical data to the landfill for facility acceptance. It was also pointed out that if the excavated material contains a high proportion of gypsum, then that will create off-gas and odor problems that may cause the excavated material to be rejected by the landfill facility.

Therefore, please issue guidance to the bidders regarding the off-site disposal of the excavated materials.

□ Response

Refer to the response to the first question above.

================================================================

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

Page 3 of 5


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

Page 4 of 5


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




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




4.) All decisions by the Administrative Review Board are final.
