updates. All materials and methods shall comply with that Specification and Supplemental

Specifications unless modified in these documents.

S-4. ADD ALTERNATIVE BID ITEMS

There are eight (8) add alternate bid items included in the project. The City shall select the

best bid based on the grand total bid on all of the items on the contract (including the Add

Alternatives) but may choose not to award one or more Add Alternate portions at the time of

the award of the rest of the project. By signing the proposal, the Contractor acknowledges that

the City may delete one or more Add Alternate portions of the bid without putting into effect

the provisions of Article 8 of the General Specifications regarding increase or decrease in

quantities. The Contractor shall review Article ix, Consideration of Bids, in the General

Specifications. The last paragraph of this article states "...the City reserves the right to award

the contract in whole or in part, whichever is in the best interests of the City." If a decision has

been made to award Add Alternate portions, the Add Alternates will be chosen in the order

listed in the plans and specifications. For example, the base bid and the acceptable Add

Alternate(s), in the order shown in the plans, will be accepted based on the available funds

allowed. Selection of the apparent low bidder will be based on a pre-determined dollar

amount, which will be disclosed prior to the bid opening. The apparent low bidder with the

most consecutive Add Alternatives beginning with Add Alternative 1 with a bid lower than the

pre-determined dollar value will be selected. If all bids are higher than the pre-determined

dollar amount, the lowest Base Bid will be selected.

S-5. STORAGE OF MATERIAL

On any corner formed by intersecting streets, the Contractor shall not permit the placement or

storage of materials and equipment or other obstructions to a height greater than three feet

above the level of the center of the adjacent intersection within the area of land formed on the

corner of the lot by measuring a distance of 50 feet along each curb line (or, if none, then each


S.P. 107-030-006



6-S

boundary line of the roadways) from the intersection of such lines, as shown in the figure

below:

Site-specific conditions may require adjustments by the Engineer in the size and location of the

clear view area as described above.

In addition, no stock pile/staging areas are provided within the project work zone. It will be the

Contractor’s responsibility to find an area to use for this if it is determined to be necessary. Any

site used shall be submitted to the Engineer for approval and will be subject to all applicable code and ordinance requirements. No compensation will be provided for the stock pile/staging

area and it will be considered incidental to the various contract unit prices.

S-6. SHOP DRAWING

Shop drawings will be accepted and reviewed by the City, the acceptance, review and/or

subsequent comments shall not be construed as approval of the shop drawings. The

responsibility of the Contractor to supply materials that comply with the specifications and plans lies entirely with the Contractor. S-7. VIBRATION

The Contractor may need to make adjustments to their construction practices if damage to

adjacent facilities may result from their operations. It is the responsibility of the Contractor to

monitor and make necessary changes if any are needed. Any monitoring or changes in

operations will be at the Contractor’s expense. S-8. MINORITY BUSINESS

The City of Bloomington (City) has adopted and strictly enforces a nondiscrimination policy,

which must be included in all contracts and subcontracts. The Contractor is directed to review

these requirements in Article 39 of the General Specifications.


S.P. 107-030-006

S-9. PREVAILING WAGE

All work under this contract shall meet the requirements set forth by the Minnesota

Department of Transportation for prevailing wage (Payment of Predetermined Minimum Wage)

rates.

The minimum hourly rates of wages required to be paid for all hours worked to the various

laborers and mechanics employed by the Contractor and subcontractors under the Contract

shall be according to the schedule contained in the Prevailing Wages for State Funded

Construction Projects of the Minnesota Department of Labor and Industry (included in

Appendix). Overtime shall be paid after 8 hours per day. The overtime rate for hours worked in

excess of 8 hours per day on this Project may not be less than one and one-half the basic hourly

rate.

Pursuant to Minnesota Statutes 177.41 to 177.44 and corresponding Rules 5200.1000 to

5200.1120, this contract is subject to the prevailing wages as established by the Minnesota

Department of Labor and Industry. Specifically, all contractors and subcontractors must pay all

laborers and mechanics the established prevailing wages for work performed under the

contract. Failure to comply with the aforementioned may result in civil or criminal penalties

The 2001 Trucking Rules (effective on public works projects advertised after June 25, 2001) will

be enforced on this Project. An overview is located at

http://www.revisor.leg.state.mn.us/arule/5200/1106.html.

S-10. SCHEDULE OF MATERIALS CONTROL

Testing rates for materials used on this Project shall be at the rates set by MnDOT State Aid for

Local Transportation’s Schedule of Materials Control, which is included with these

S.P. 107-030-006



8-S

S-13. MOBILIZATION

Mobilization on this Project shall be in accordance with MnDOT 2021. The Contractor shall

anticipate that numerous remobilizations are common on this type of project.

S-14. RESPONSIBLE CONTRACTOR

REVISED 06/04/15

The Department cannot award a construction contract in excess of $50,000 unless the Bidder is

a “responsible contractor” as defined in Minnesota Statutes §16C.285, subdivision 3. A Bidder

submitting a Proposal for this Project must verify that it meets the minimum criteria specified in

that statute by submitting the “Responsible Contractor Verification and Certification of

Compliance” form. A company owner or officer must sign the “Responsible Contractor

Verification and Certification of Compliance” form under oath verifying compliance with each of

the minimum criteria. THE COMPLETED FORMS MUST BE SUMITTED WITH THE BID PROPOSAL.

A bidder must obtain a verification from each subcontractor it will have a direct contractual

relationship with. At the Department’s request, a bidder must submit signed subcontractor

verifications. A contractor or subcontractor must obtain an annual verification from each

motor carrier it has a direct contractual relationship with. A motor carrier must give immediate

written notice if it no longer meets the minimum responsible contractor criteria. The

requirement for subcontractor verifications does not apply to:

• Design professionals licensed under Minnesota Statutes §326.06; and

• A business or person that supplies materials, equipment, or supplies to a

subcontractor on the Project, including performing delivering and

unloading services in connection with the supply of materials, equipment,

and supplies. But, a business or person must submit a verification if it

delivers mineral aggregate such as sand, gravel, or stone that will be

incorporated into the Work by depositing the material substantially in

place, directly or through spreaders, from the transporting vehicle.

A bidder or subcontractor who does not meet the minimum criteria specified in the statute, or

who fails to verify compliance with the criteria, is not a “responsible contractor” and is

ineligible to be awarded the Contract for this Project or to work on this Project. Submitting a

false verification makes the bidder or subcontractor ineligible to be awarded a construction

contract for this Project. Additionally, submitting a false statement may lead to contract

termination. If only one bidder submits a bid, the Department may, but is not required to,

award a contract even if that bidder does not meet the minimum criteria.


S.P. 107-030-006

S-15. (1801) SUBLETTING OF CONTRACT

REVISED 6/4/15

The provisions of MnDOT 1801 are modified as follows:

S-15.1 For Projects in excess of $50,000, the Contractor may sublet work only to

subcontractors that meet the definition of “responsible contractor” in Minnesota

Statutes §16C.285, subdivision 3. The Contractor shall obtain verifications of

compliance with §16C.285 from subcontractors using a form provided by the

Department. The Contractor must provide such verifications to the Department upon

the Department’s request.

S-15.2 The third paragraph of MnDOT 1801 is modified to read:

On Contracts with Disadvantaged Business Enterprise (DBE), the Contractor's

organization shall perform Work amounting to not less than 30 percent of the total

original Contract Amount. The Department will deduct specialty items from the total

original Contract Amount before calculating the amount of Work that the Contractor

shall perform.

S-16. COMPLIANCE WITH TAX LAW REQUIREMENTS

The Department cannot make final payment to the Contractor until the Contractor

demonstrates that it and all its subcontractors have complied with the Income Tax withholding

requirements of Minnesota Statutes, section 290.92 for wages paid for work performed under

the contract. To establish compliance, the Contractor must submit a “Contractor Affidavit”

either online or in paper form (IC134) to the Minnesota Department of Revenue. The contractor

will receive written certification of compliance when the Department of Revenue determines

that all withholding tax returns have been filed and all withholding taxes attributable to the

work performed on the contract have been paid. The Contractor must then provide this written

certification to the Department to receive final payment.

Every subcontractor working on the Project must submit an approved “Contractor Affidavit”

from the Minnesota Department of Revenue to the Contractor before the Contractor can file its

own Contractor Affidavit. The Contractor is advised to obtain the certification from each

subcontractor as soon as the subcontractor completes work on the Project. Experience has

shown that waiting until the project is complete to obtain the forms from all subcontractors

is likely to result in significant additional work for the Contractor as it will be difficult or

impossible to collect all forms.

The Department of Revenue, in association with the Department of Employment and Economic

Development, offers a free seminar to help contractors understand tax law requirements. The


S.P. 107-030-006



10-S

Department strongly urges the Contractor and all subcontractors to attend the “Employment

Taxes & Employer Responsibilities Seminar” or similarly offered classes. You can find a schedule

and more information on the Department’s website at:

www.revenue.state.mn.us/businesses/withholding/Pages/EducationandOutreach.aspx.

Complying with this requirement is considered part of the Work under this contract. The

Department will enforce this requirement equally with all other Contract requirements.

Contractor delay in complying with this requirement will cause the Department to delay final

payment and Contract Acceptance. The Department may also report non-compliance to the

Department of Revenue, which may result in enforcement action by the Department of

Revenue.

S-17. EMERALD ASH BORER COMPLIANCE

REVISED 01/08/16

S-26.4 Temporary Pedestrian Access Control (2563)

This work shall consist of providing Temporary Access Control Plan. This plan shall

consist of identifying a Temporary Pedestrian Accessible Route (TPAR) and features

needed to assist pedestrian, bicyclists and non-motorized vehicles safe movement

within and around the construction zone. This work shall be done in accordance with

Contract provisions and the following:

The Contractor shall develop and provide for a continuous Temporary Pedestrian

Accessible Route (TPAR) for this Project. The TPAR shall clearly address all non-

motorized users in the construction zone. The Contractor shall submit this plan to the

Engineer for acceptance at the pre-construction meeting.

PEDESTRIAN ACCESS

(A) The TPAR must have a minimum width of 48 inches (4 feet) and guide

pedestrians through and/or around the Project by using devices such as signage,

barricades, and temporary curb ramps or blended transitions. The Contractor

may provide an alternate route that is accessible and within 2 block(s) offset of

the closed construction area. To the maximum extent feasible, the TPAR shall be

provided on the same side of the street as the disrupted route. Where the TPAR

is exposed to adjacent construction, excavation drop-offs, traffic, or other

hazards, it shall be protected with a pedestrian barricade or channelizing device.

All TPARs must have a smooth, level, slip-resistant surface and shall meet the

applicable requirements of the Public Right-of-Way Accessibility Guidelines

(PROWAG).

(B) The Contractor shall schedule and coordinate the replacement of the pedestrian

access to accommodate the needs of the business and residences. Existing

sidewalks shall be left in-place until such time that it is required to remove them

to accommodate new construction. Pedestrian access may be provided to

businesses and homes through the use of any public access from adjacent


S.P. 107-030-006



19-S

parking lots and side streets. Front door access must be provided to buildings

without alternate public entrances. Where disrupted by construction, the

Contractor must provide a continuous TPAR for all areas disrupted construction

throughout all phases of construction.

(C) For technical provisions on TPAR, the Contractor is directed to the Guidelines for

Accessible Public Rights-of-Way at: http://www.access-

board.gov/prowac/draft.htm and Chapter 6D of the MnMUTCD. The pedestrian

accessibility checklist is on page 6D-5 and 6D-6 of the MnMUTCD. The Contractor

shall complete MnMUTCD Fig. 6D-1, “Pedestrian Accessibility Considerations in

Temporary Traffic Control Zones Check List”. A copy shall be provided to the

Engineer at the pre-construction meeting.

(D) The Contractor shall notify the Engineer in writing at least 72 hours prior to the

start of any construction operation that will necessitate a change in pedestrian

access.

Traffic control devices must allow for an accessible route through the Project. TPAR

pedestrian barricades and channelizing devices shall be continuous, stable, and non-

flexible and shall consist of a wall, fence, or enclosures. The base of any traffic control

devices shall be a continuous raised barrier of no more than 6 inches in height and must

allow for drainage. The purpose of this barrier is to provide a continuous wayfinding

device for the visually impaired, therefore the barrier shall not have any points that

might catch a person who is using a cane for a guide. The Devices shall provide a

continuous surface or upper rail at a minimum 3 feet above the ground or walkway

surface. Support members shall not protrude into the path. Whenever possible the

TPAR shall only utilize in-place street crossings. TPAR must be regularly inspected and

updated depending on Project staging.

No pedestrian curb ramp or blended transition work shall occur concurrently at adjacent

intersections.

The Contractor shall be responsible for maintaining the TPAR within this Project. The

Contractor shall furnish the name, addresses, and phone number of at least one

individual responsible for the placement and maintenance of TPAR. This individual shall

be "on call" 24 hours per day, seven days per week during the times any devices,

furnished and installed by the Contractor, are in place. The required information shall be

submitted to the Engineer at the pre-construction meeting.

The Contractor shall be expected to answer calls immediately and begin corrective

measures needed within one hour. If the Contractor is negligent in correcting the


S.P. 107-030-006



20-S

deficiency within one hour of notification the Contractor shall be subject to a monetary

deduction at the rate of $100.00 per hour when only one residence or location is

affected and at the rate of $500.000 per hour in all other cases that the Engineer

determines the Contractor has not complied.

The Contractor is advised that the corridor has Transit service. Re-locations of stops can

only be made with the approval of the Engineer.

Only one side of the roadway may be disrupted at a time for pedestrian curb ramp,

blended transition, or sidewalk construction. Where it is not feasible to provide a same-

side TPAR and pedestrians will be detoured, the alternate route must provide a similar

level of accessibility to the existing route. This may include the incorporation of

accessible pedestrian signals (APS), curb ramps, or other accessibility features.

All traffic control required under this Contract for pedestrian access shall be performed

as incidental work for which no direct payment will be made.

The Contractor may ban parking within the construction limits with the approval of the

Engineer. All necessary signing is the responsibility of the Contractor and shall be

installed, as directed by the Engineer, 24 hours prior to the parking ban. The Contractor

shall remove that signing as soon as the work or that part of the work, in the area has

been completed.

26.4.1 Traffic Control Inspection Log

During the time that any traffic control devices, furnished and installed by the

Contractor, are in place, the Contractor shall provide a person on a daily basis to inspect

and ensure that all traffic control devices required are installed properly and conform to the MnMUTCD. Any discrepancy between the actual devices in use and the required

devices shall be immediately rectified.

This log shall also include the date and time any changes in the stages, phases, or

portions thereof go into effect. The log shall identify the location and verify that the

devices are placed as directed or corrected in accordance with the Plan. All entries in the log shall include the date and time of the entry and be signed by the person making

the inspection. The person or persons performing the inspection shall be required to

make a daily log (including weekends and holidays) of these inspections.

Copies of these logs must be submitted to the Engineer each Monday while there is traffic control on the Project. No payment for Traffic Control will be made until these

logs have been received and approved by the Engineer.

directing traffic.


S.P. 107-030-006



23-S

The Contractor will be subject to a non-compliant charge for failure to adhere to the

clothing requirements as listed above. Non-compliant charges, for each incident, will be

assessed at a rate of $ 500.00 per incident that the Engineer determines that the

Contractor has not complied.

Except as otherwise authorized by the Engineer, the maximum length of the flagging

operation shall be no more than 1.6 km [1 mile].

The Contractor shall coordinate the flagging operations in a manner which causes as little delay to the traveling public as possible, and at no time shall the delay exceed five

(5) minutes. In the event that the Contractor is unable to meet the maximum delay

requirements, operations shall shut down until such time a new traffic control plan is

developed which does meet the maximum delay requirement.

If hauling operations create hazards for the traveling public, the Contractor will be

required to provide additional flaggers, as directed by the Engineer. All costs incurred to

provide the additional flaggers shall be incidental to the lump sum traffic control.

The Contractor shall furnish off-duty police officers in uniform with cars and an orange reflectorized vest to direct the traffic if deemed necessary and so ordered by the

Engineer. “Police Officer” means every officer authorized to direct or regulate traffic or

to make arrests for violations of traffic rules. No direct payment for police officers will

be made; this work shall be incidental to the lump sum traffic control.

The Engineer will have the right to waive the above requirements.

26.4.5 Temporary Lane Closure Requirements

Unless otherwise authorized by the Engineer, any temporary lane closure extending to or beyond 300 m [1000 feet] shall have a minimum of one, Type III barricade placed in

closure taper and also in any shifts in traffic alignment.

Temporary lane closures will not be permitted during inclement weather, nor any other

time when, in the opinion of the Engineer, the lane closure will be a greater than normal hazard to traffic.

Temporary lane closures or other restrictions by the Contractor, during work hours and

consistent with the time restrictions, will be permitted during those hours and at those

locations approved by the Engineer. Requests for temporary lane closures shall be


S.P. 107-030-006



24-S

made at least 24 hours prior to such closures. When a temporary lane closure is used by

the Contractor, the closure shall be incidental work and no direct compensation will be

made therefore.

26.4.6 Signal And Lighting Systems

The Contractor shall not interfere with the operation of any traffic signal system, except

as required by the Contract. The Contractor shall notify the Engineer at least 48 hours

prior to beginning any work that will interfere with any traffic signal system or its detectors.

operations with those of the other Contractors on these projects:

A. PMP Street Improvement Project (City Project 2016-101)

B. PMP Street Maintenance Project (City Project 2016-102)

S-30. (1506) SUPERVISION BY CONTRACTOR


The Contractor will be subject to an hourly charge for failure to comply with the requirements

of MnDOT 1506. Non-Compliance charges, for each incident, will be assessed at a rate of $100

per hour, for each hour or portion thereof, during which the Engineer determines that the

Contractor has not complied. No charge will be made if the deficiency is corrected within one

(1) hour of notification.

An incident of Non-Compliance will be defined as the receipt of a written work order by the

Contractor with instructions to correct a deficiency.

The Contractor shall designate, in writing, who the competent superintendent and the

competent individual (i.e.: construction team leader or foreperson) will be for the Project. These

persons can only be changed during the Project by submission of a written authorization request

to the Engineer by the Contractor. The submittal of information (including a personal resume

and listing of other projects of similar magnitude where each has worked in a position of similar


S.P. 107-030-006



27-S

responsibility, and current contact information for a direct supervisor on the projects listed)

regarding these persons and one back-up individual shall be submitted at the preconstruction

conference. These persons shall not be an operator or laborer. The competent individual shall

be available to the Project at all times and the competent superintendent will be required to be

on the site at least daily while working days are being assessed. The Engineer may decide to require the Superintendent to be on the site more frequently if necessary.

The Contractor shall furnish names, addresses, and phone numbers of at least three individuals

responsible for all aspects of maintenance (including traffic control devices) on the Project.

These individuals shall be “on call” 24 hours per day, seven days per week. The individual “on

call”, upon receiving notification of any deficiency, shall dispatch people, materials, and equipment to correct the deficiency within one hour of notification.

All of the above information shall be submitted to the Engineer at the Pre-Construction

Conference.

S-31. (1507) EXISTING UNDERGROUND UTILITIES

Construction operations in the proximity of utility properties shall be performed in accordance

with the provisions of MnDOT 1507, except as modified below:

The plan will indicate the quality level of the subsurface utility information according to the

guidelines of CI/ASCE 38-2 entitled “Standard Guidelines for the Collection and Depiction of

Existing Subsurface Utility Data”. If no quality level is indicated, the Contractor shall assume it

is quality level D. Every effort has been made to position and dimension all existing

underground utilities on the Plans. This information was obtained from the respective utility

companies and the City record plans. The City of Bloomington does not guarantee the locations

as shown on the Plans. It is the Contractor’s responsibility to ascertain the final location of

these utilities (including municipal water and sewer lines and appurtenances) and to notify the

utility companies when construction commences in each area. The Contractor shall contact

Gopher State One-Call (651-454-0002) at least 48 hours (excluding Saturdays, Sundays and

holidays) prior to any excavation.

It is the intent of this project to avoid in-place public and private utilities. New utility

installations as part of this project will cross existing utilities. Where utility crossings are

anticipated, the Contractor shall expose (pothole) the utility in question to determine whether

there will be a conflict with the proposed work before that work has started. No payment shall

be made for time delays due to utility conflicts or for this exploration. Restoration of surfacing

disturbed by utility potholing excavations shall be in accordance with the requirements of these

Special Provisions and the required Excavation and Work within the Right-of-Way Permits

described elsewhere in these Special Provisions.

The Contractor is responsible for the protection of all underground utilities, which are located


S.P. 107-030-006



28-S

in the field or are shown on the plans. All damage to existing manholes, gate valves, curb stops,

etc. must be reported. The report shall be a written list detailing the location of the utility and

the damage discovered by the Contractor. The listing must be submitted before any work

begins or the Contractor will be held responsible for repairs. The Contractor is encouraged to

inspect such items before construction begins and must inform the Engineer in writing.

Boulevard areas may contain buried underground utilities that are not located by the Gopher

State One Call system. The most common type of this is adjacent private lighting systems and

irrigation systems. The Contractor shall contact adjacent property owners to assist in locating

these facilities if they are not located with the One Call system and it is reasonable to assume

that they exist in the boulevard. The Contractor may need to provide and operate locating

equipment to facilitate the locating effort (incidental). The Contractor shall protect these

utilities (incidental) or the City shall issue a Work Order to move the facilities. If the Contractor

does not make a reasonable effort to contact the property owner and protect the facility,

damages caused by the Contractor will be the responsibility of the Contractor.

Cooperation and coordination with other Contractors, and Utility Companies, working in the

area of this construction will be necessary for the successful completion of this project.

S-32. (1513) RESTRICTIONS ON MOVEMENT AND STORAGE OF HEAVY LOADS AND

EQUIPMENT

The provisions of Mn/DOT 1513 are hereby deleted and replaced with the following:

S-34. (1601) SOURCE OF SUPPLY AND QUALITY



S.P. 107-030-006



30-S

In conformance with the provisions of the U.S. Code of Federal Regulations 23CFR635.410 the

Contractor will furnish and use only steel and iron materials that have been melted and

manufactured in the United States,. Foreign source materials are any domestic products taken

out of the United States for any process (e.g. change of chemical content, permanent shape or

size, or final finish of product).

All bids must be based on furnishing domestic iron and steel, which includes the application of

the coating, except where the cost of iron and steel materials incorporated in the work does

not exceed one-tenth of one percent of the total Contract cost or $2,500.00, whichever is

greater. The state may approve the use of foreign iron and steel materials for particular

Contract items, provided the bidder submits, a stipulation identifying the foreign source iron

and/or steel product(s) and the estimated invoice cost of the product(s), for one or more of the

Contract bid items. The Contractor shall submit a "Stipulation for Foreign Iron or Steel

Materials" form for each stipulation with the Contractor's proposal. If the Contractor chooses

to use ANY non-domestic iron or steel, the Contractor must submit a stipulation with the

proposal.

Prior to performing work the Contractor shall submit to the Engineer a certification stating that

all iron and steel items supplied are of domestic origin, except for non-domestic iron and steel

specifically stipulated and permitted in accordance with the paragraph above.

S-34.1 Source Supply and Quality

MnDOT 1604 is supplemented as follows:

All costs of shop inspection at plants outside the United States shall be borne by the Contractor.

Monies due or to become due the Contractor will be reduced according to these costs.

S-34.2 Partial Payment

All provisions for partial payments shall apply to domestic materials only. The Contractor will

not receive payment for materials manufactured outside of the United States until such

materials are delivered to the job site.

S-34.3 Alternative Bidding Process

Unless an alternate bidding process is specified, use of foreign steel and iron products in

quantities in greater than provided above is not permitted. When the alternate bidding process

is permitted the Contract may be awarded to the bidder who submits the lowest total bid

based on furnishing domestic iron or steel unless such total bid exceeds the lowest total bid


S.P. 107-030-006

based on foreign materials by more than 25 percent.

S-35. (1701) LAWS TO BE OBSERVED - CARGO PREFERENCE ACT; USE OF UNITED STATES -

FLAGGED VESSELS

The provisions of 1701 are supplemented with the following:

S-35.1 The Contractor must utilize privately-owned United States-flag commercial vessels to

ship at least 50% of the gross tonnage whenever shipping any equipment, material, or

commodities pursuant to this Contract. This requirement applies only to the extent that

such U.S.-flag vessels are available at fair and reasonable rates. Compute gross tonnage

separately for dry bulk carriers, dry cargo liners, and tankers. The term “pursuant to this

Contract” means this provision applies to materials or equipment acquired for this

specific Project. Materials used for highway construction generally originate from

existing inventories rather than being acquired solely for a specific project. For

example, the requirements generally do not apply to shipments of Portland cement,

asphalt cement, or aggregates, as suppliers and contractors use these materials to

replenish existing inventories. But, the Cargo Preference Act does apply if any material

or equipment is acquired solely for this specific Project.

S-35.2 The Contractor must furnish a legible copy, in English, of a rated, “on-board”

commercial ocean bill of lading for each shipment of cargo described in clause S-35.1.

The Contractor must provide the bill of lading to the Department and to the following:

Division of National Cargo

Office of Market Development

Maritime Administration

Washington DC, 20590

The Contractor must provide the bills of lading no later than 20 days after the date of

loading for shipments originating within the U.S.A., or no later than 30 days after the

date of loading for shipments originating outside the U.S.A.

S-35.3 The Contractor must include or incorporate this provision in all subcontracts.

S-36. (1702) PERMITS, LICENSES, AND TAXES

The Contractor shall be required to obtain and pay for all permits for this project unless

otherwise specified in these Special Provisions. All permits required, shall be construed to be

part of the Special Provisions. The conditions, requirements and restrictions of these permits

shall be binding on the Contractor’s operation under this Contract.

The Contractor’s designee(s) shall be responsible for correcting violations on the Project as

observed by the Engineer or designated representative.

The Contractor is hereby advised that the City of Bloomington has determined that all existing

manholes, catch basins, and similar type enclosed structures on storm sewer systems, water

distribution systems, and sanitary sewer systems contained within the right of way of all

roadways and within the construction limits of this Project are confined spaces and access into

them shall be in accordance with the MINN.RULE5207.0300-0304. All new structures of the

same type and function of the aforesaid which are to be constructed as a part of this Project shall also be considered confined spaces and access into them shall be in accordance with the

OSHA Regulation 29 CFR 1910. Further, the Contractor shall be required to abide by the Permit-

Required Confined Space Policy and Contractor Safety and Health Policy of the City of

Bloomington, in addition to the 29 CFR 1910 Occupational Safety & Health Administration

• Continuous edging may be required to delineate a pedestrian pathway throughout

the facility so a long cane can follow it, if the pedestrian pathway is not otherwise

distinguishable.

• A smooth, continuous hard surface that will not cause tripping or restrict wheel chair

use will need to be provided.

• A minimum width of 5 feet throughout the entire length of the pedestrian pathway

is required. If it is not possible to provide and maintain this width, a 5 foot x 5 foot

passing space should be provided at least every 200 feet to allow individuals in

wheelchairs to pass. In no case shall the width of the pedestrian pathway be less

than 3 feet.

S-40.1 Temporary Lane Closure Requirements

Work which will restrict or interfere with traffic shall not be performed between 12:00 noon

on the day preceding and 9:00 A.M. on the day following any consecutive combination of a

Saturday, Sunday and legal holiday.

Lane closures on City and County streets may be restricted to hours between 9 AM and 3 PM.

Unless otherwise approved by MnDOT, and the City of Bloomington, temporary lane closures

on MnDOT roadways shall be in accordance with allowable lane closures identified in the

current version of the Lane Closure Manual except as modified by this section of the special

provisions:

http://www.dot.state.mn.us/metro/trafficeng/laneclosure/index.html

For this project, the Lane Closure Manual shall be modified as follows:

- Where day time lane closures are allowed in the Lane Closure Manual, they shall occur

on Monday through Friday only for this project. No day time lane closures will be

allowed on MnDOT roadways on Saturdays and Sundays.

- Where night time lane closures are allowed in the Lane Closure Manual, they will be

limited to Sunday, Monday, Tuesday, and Wednesday nights of the week, in addition

to other restrictions specified in the Lane Closure Manual or in these Special

Provisions.

The Engineer will have the right to lengthen, shorten, or otherwise modify the foregoing

periods of restrictions as actual traffic conditions may warrant. If the Contractor is negligent in

adhering to the established time schedules, the Contractor shall be subject to an hourly

charge assessed at a rate of $500.00 per hour for each hour or any portion thereof with which

the Engineer determines that the Contractor has not complied.


S.P. 107-030-006



38-S

Temporary lane restrictions and/or closures for removing and/or erecting overhead structures

will only be permitted between the hours identified in the Lane Closure Manual and as

approved by the Engineer. If the Contractor requests to close the road and the Engineer

approves that it is necessary to temporarily detour traffic in order to remove or set the

structures, the Contractor shall furnish the detour as directed by the Engineer. The temporary

detour shall be incidental work for which no direct compensation will be made. If the

Contractor is negligent in adhering to the established time schedules, the Contractor shall be

subject to an hourly charge assessed at a rate of $500.00 per hour for each hour or any

portion thereof with which the Engineer determines that the Contractor has not complied.

The Contractor may stop all traffic on any road open to traffic to erect or remove overhead

structures for periods of time not to exceed fifteen minutes only from 1:30 A.M. to 5:00 A.M. or

as allowed in the Lane Closure Manual, whichever is more restrictive. The Contractor shall

allow sufficient clearance time between stopped periods so as to cause as little delay to traffic

as possible. If the Contractor is negligent in adhering to the established time schedules, the

Contractor shall be subject to an hourly charge assessed at a rate of $500.00 per hour for each

hour or any portion thereof with which the Engineer determines that the Contractor has not

complied.

No center lane closures will be permitted. Only double lane closures as shown in the Field

Manual of the MN MUTCD will be allowed at the times as directed by the Engineer. This may

require night lane closures if traffic volumes warrant.

The Contractor shall furnish off-duty police officers in uniform with cars and an orange

reflectorized vest to direct traffic if deemed necessary and so ordered by the Engineer. "Police

Officer" means every officer authorized to direct or regulate traffic or to make arrests for

violations of traffic rules. This shall be incidental work for which no direct payment will be

made.

Flag persons may be required during these restrictions in traffic flow. Exclusive of these times,

two minimum of 11’ wide lanes of traffic (or width stated on the plan) shall be kept open at all

times on city streets. Lane widths on MnDOT roadways shall match existing widths. No lane

width reduction will be allowed without prior approval by the Engineer.

S-40.2 Portable Changeable Message Signs

A Portable Changeable Message Sign (PCMS) shall be provided in advance of each temporary

lane closure on MnDOT roadways to communicate real time information.

(PCMS) Type C Trailer Mounted Message Signs will be permitted and shall be on the qualified

products list for portable changeable message signs as found at:

http://www.dot.state.mn.us/products/workzone/electronic.html. It is imperative that the

Contractor continually operate each PCMS at maximum legibility. Many factors, such as


S.P. 107-030-006



39-S

mechanical problems, insufficient charging, incorrect intensity settings, or other factors can

degrade performance. If at any time the Contractor fails to operate a PCMS at maximum

legibility, as determined by the Engineer, no payment will be made for each day that the

Message Sign is deemed inadequate.

Except as approved by the Engineer, the message sign shall be stored off the shoulder when not

in use. In the event the Engineer allows the message board to remain on the shoulder the

message sign shall be delineated according to Layout 4 (Partial Shoulder Closure) in the field

manual, as determined by the Engineer.

All costs incurred to provide Portable Changeable Message Signs shall be incidental work for

which no direct compensation will be made.

S-40.3 Temporary Signs

All temporary rigid signs shall be fabricated with an approved retroreflective sheeting material

of the appropriate color, and be listed on the Qualified Product Listing (QPL) for either

“Sheeting for Rigid Signs” or “High Performance Sheeting for Rigid Signs”. Signs remaining in-

place that still apply during temporary operations need no change in sign sheeting.

To visually identify approved retroreflective sign sheeting on temporary rigid signs in the field

signs shall have an easily identifiable marking on the face. This marking verifies that the sign

sheeting is Approved for Rigid Sign Use as found on the APL. Although still required to meet

sheeting standards, temporary rigid signs 4 sq. feet and under in size and all barricades and

route markers will be exempt from this marking. The appropriate marking shall be used for

each type of the approved sheeting types, consisting of Type IX and Type HP (also marked as

DG3). Refer to the instructions for the marking of temporary signs which may be found on the

APL or directly at the following link:

http://www.dot.state.mn.us/products/signing/common/typelabel.pdf

The retroreflective sheeting types and qualified products used for temporary signs and

barricades can be found at: http://www.dot.state.mn.us/products/signing/sheeting.html.

S-41. (1710) TRAFFIC CONTROL DEVICES

All traffic control devices and methods shall conform to the Minnesota Manual on Uniform

Traffic Control Devices (MN MUTCD), Minnesota Standard Signs Manual Parts I and II, the

Traffic Engineering Manual, and the following:

On any roadway having a 45 mph or higher speed limit prior to construction, all Category I and

II temporary traffic control devices used after July 1, 2006 shall meet NCHRP 350 crash testing

criteria. This includes all new and used Category I and Category II devices. Category I devices


S.P. 107-030-006



40-S

include tube markers, plastic drums and cones, etc. Category II devices include portable sign

supports, Type I ,II and III barricades, etc.

One any roadway having a speed limit between 0-40 mph, all Category II temporary traffic

control devices used after January 17, 2010 shall be considered crashworthy which is defined as

“a characteristic of a roadside appurtenance that has been successfully crash tested in

accordance with a national standard such as the National Cooperative Highway Research

Program Report 350, ‘Recommended Procedures for the Safety Performance of Highway

Features’” and meet the requirements of MN MUTCD.

The Contractor is hereby advised that the MN MUTCD requires that all signs shall meet the

NCHRP 350 crash testing criteria.

The Contractor shall provide the Engineer a Letter of Compliance stating that all of the

Contractors Category I and II Devices are NCHRP 350 approved as of July 1, 2006. The Letter of

Compliance must also include approved drawings of the different signs and devices and shall be

provided to the Engineer at the Pre-construction meeting.

All traffic signs requiring removal due to construction operations shall be neatly stored and

protected on site by the Contractor and remain until reinstalled by the Contractor. If the

Contractor damages any sign during the salvage operation, and the Engineer determines that

the damaged sign cannot be reused, the Contractor shall dispose of the damaged sign and

furnish a new replacement sign in accordance with the applicable fabrication specifications at

no cost to the City. No payment will be made for either the salvaging or reinstallation of the

signs unless specifically listed as a pay item.

S-42. (1712) TREE PROTECTION

When excavation for any reason is required near any trees, that excavation must be done by

hand methods so the damage to the roots is held to a minimum.

The Engineer may direct the Contractor to protect trees that remain in place within the

construction area with snow fencing placed at the outer limits of the branches (drip line) before

work begins.

If any roots are damaged they must be cut off cleanly and smoothly, and immediately painted

with an approved tree paint. If the trunk or a limb of a tree is inadvertently damaged, it must

immediately be repaired as directed by the Engineer.

There is no pay item for tree protection on this Project. All work shall be incidental work for

which no direct compensation will be made.

S-43. (1714) RESPONSIBILITY FOR DAMAGE CLAIMS


S.P. 107-030-006



41-S

Responsibility for damage claims shall be in accordance with the provisions of MnDOT 1714,

except as modified as follows:

The Contractor shall indemnify, defend and save harmless the City of Bloomington, the

County of Hennepin, their officers, agents and employees from all suits, actions, and

claims of any character brought because of injuries or damages received or sustained by

any person, persons, or property on account of the operations of the said Contractor; or

on account of or in consequence of any neglect in safeguarding the work; or through use

of unacceptable materials in constructing the work; or because of any act or omission,

neglect, or misconduct of said Contractor; or because of any claims arising or amounts

recovered from infringements of patent, trademark, or copyright; or because of any

claims arising or amounts recovered under the Workers Compensation Act; or under

any other law, ordinance, order, or decree.

In addition to the insurance requirements listed in Section 36 of the General Specifications the

Contractor shall provide the following insurance coverage. If a discrepancy arises between the

General Specification and these Special Provisions, the higher limit or more restrictive condition

shall govern.

Responsibility for damage claims shall be in accordance with the provisions of MnDOT 1714,

except as modified as follows:

S-43.1 Commencement of Work

In the event any work to be performed under this Contract is further sublet, Contractor will

require the same insurance coverage, additional insured endorsements (ISO CG 20 10 1985

version or equivalent) and limits from its subcontractors, and will require said subcontractors

to certify insurance coverage to the City and County as outlined above (including at any time

certified copies of all insurance policies and endorsements), prior to the commencement of

any work.

Notwithstanding any other provision of this Agreement to the contrary, no officer, employee

or agent of the City is authorized to cause, suffer, or permit the Contractor or any of its

employees, guests, agents, subcontractors, or suppliers to commence or perform any work or

otherwise enter upon the project site unless and until all of the conditions of this Article have

been conformed to and performed.

The Contractor shall not commence work until it has obtained required insurance and filed

with the City a properly executed Certificate of Insurance which clearly evidences the required

insurance coverages. The certificate shall name City of Bloomington as the certificate holder,

and shall also name Hennepin County and the City of Bloomington as additional insureds for

the Commercial General Liability coverage with respect to operations covered under the


S.P. 107-030-006



42-S

Contract. The certificate should also show that City of Bloomington will receive 30 days prior

written notice in the event of cancellation, nonrenewal, or material change in any described

policies.

The Contractor shall furnish to the City updated certificates during the term of the Contract as

insurance policies expire. If the Contractor fails to furnish proof of insurance coverages, the City

may withhold payments and/or pursue any other right or remedy allowed under the Contract,

law, equity, and/or statute.

S-43.2 Other Liability Policy Requirements

The Contractor shall maintain insurance with these provisions:

Except as to Workers’ Compensation, Employers’ Liability and Professional Errors & Omissions

insurance, the City and County shall be named as additional insured under ISO form CG 20 10

1985 version or the equivalent as approved by City. The City and County as an additional

insured shall have all the rights, coverages, and limits afforded the Contractor under the

policies. In the event that any insurer issues a reservation of rights for City and County as an

additional insured, City and County shall be entitled to employ independent counsel at

Contractor’s expense.

For all insurance policies required or referenced in this agreement, Contractor agrees to

waive and shall require all Contractors of every tier to waive all subrogation rights on behalf

of itself and it’s insurers (or in the alternative to secure the waiver of subrogation from its

insurers) against City and County and all of City and County’s employees and agents.

That Contractor’s insurance is primary and any insurance maintained by City or County is

considered excess and non-contributory. This provision in no way waves the tort liability

caps stated in Minn Stat. § 466, as may be amended from time to time.

Liability insurance policies (except for professional errors and omissions) must be a claims

occurrence policy form, and not a claims made type of policy.

The City must approve the insurance companies and all insurance companies shall maintain at

all times a rating of A- or higher by A.M. Best. It shall be considered a material breach of this

contract if at any time before, during or after completion of the project as required in this

agreement for Contractor or any of its subcontractor’s insurance to be cancelled, non-renewed,

reduced in coverage below that required in this agreement, or an insurance carrier rating is

reduced below an A- as rated by A.M. Best (and Contractor has not obtained qualifying

alternative insurance from an approved carrier).

S-43.3 Removal of Liens


S.P. 107-030-006



43-S

Any liens filed on a project which are not promptly removed constitute a default. To remove

a lien the Contractor is required to post a bond, deposit money, or meet any other statutory

requirement.

S.P. 107-030-006



72-S

Submit two sets of prints of required shop detail drawings, meeting 2471.3.B.2, “Format,” from the

fabricator to the Engineer for review and release for fabrication. Shop drawings must comply with the contract documents. Provide written authorization from the design EOR (Engineer of Record) for any deviation from the contract documents. Incorporate all contractor comments into shop drawings prior to submittal to reviewer. The reviewer will return one set of prints of the shop detail drawings to the Fabricator with comments.

Submit only checked drawings, in complete collated sets, from the fabricator for review. The Contractor

may submit details such as ice-breakers, anchorages, bearing plates, and castings, separately to facilitate the work.

Fabricator may submit the shop drawings to the Contractor. Stamp these drawings with "For Contractor Use Only". Do not forward these stamped drawings to MnDOT.

Submit a schedule showing the submission dates of shop drawings and anticipated dates for shop

fabrication from the fabricator, as directed by the Engineer. Arrange the schedule to avoid delay in completing the work. If constructing a structure composed of several units, consider submitting shop detail drawings of the separate units in proper order to expedite the review and release for fabrication of the details.

If the Engineer requests changes to the submitted drawings or if the fabricator makes additional changes not

required by the Engineer, provide revised drawings, with revision control, from the fabricator with circles, underscores, or other marks to distinguish the changes from unchanged details or dimensions.

The Engineer will release shop detail drawings for fabrication after corrections are completed. Provide six

sets of corrected drawings and additional copies as required by the contract or requested by the Engineer from the fabricator at no additional cost to the Department. Mark the corrected drawings as Revision 0 and remove all comments and marks to make clean drawings for approval, stamping and distribution for use.

The shop drawings approved by the Engineer will become part of the Contract. Do not make changes on

approved drawings unless otherwise approved by the Engineer in writing. Mark changes approved by the Engineer on the approved shop drawings with revision version in number sequence next to all changes and resubmit them for approval, stamping as revised sheet and distributing to replace the superseded version of drawings.

The Engineer‘s approval of shop drawings will not relieve the Contractor of full responsibility for

submission of complete and accurate drawings and for the accurate assembly and fitting of all structural members. S-55.2 The entire section of MnDOT 2471.3.M.1.d, "Radiographic Testing (RT)," is deleted and replaced with the following:

Provide Computed Radiography (CR) or Digital Radiography (DR) in lieu of conventional radiography. The Department will retain ownership of radiographic images provided by the Contractor. Name image files with bridge number and weld identification shot number.

Electronic Radiography method(s) consist of CR utilizing Storage Phosphor Imaging Plate (SPIP) or DR

utilizing a Digital Detector Array (DDA).

Ensure CR complies with ASTM E2033, "Standard Practice for Computed Radiology (Photostimulable Luminescence Method)," and ASTM E2445, "Standard Practice for Performance Evaluation and Long-Term Stability of Computed Radiography Systems". Ensure DR complies with ASTM E2698, "Standard Practice for Radiological Examination Using Digital Detector Arrays," and ASTM E2737, "Standard Practice for Digital Detector Array Performance Evaluation and Long-Term Stability".


S.P. 107-030-006



73-S

Ensure SPIP and DDA widths are sufficient to depict all portions of the weld joint, including the HAZs, and provide sufficient additional space for the required hole-type or wire-type IQIs and radiograph identification without infringing upon the area of interest.

Ensure all radiographs radiographic images are free from mechanical, chemical, or other blemishes to the

extent that they cannot mask or be confused with the image of any discontinuity in the area of interest in the radiograph. Such blemishes include, but are not limited to the following:

(1) False indications due to defective plates or internal faults; and (2) Artifacts due to non-functional pixels.

Ensure the contrast and brightness range that demonstrates the required sensitivity be considered valid

contrast and brightness values for interpretation. When multiple IQIs are utilized to cover different thickness ranges the contrast and brightness range that demonstrates the required IQI image of each IQI is determined. Intervening thicknesses may be interpreted using the overlapping portions of the determined contrast and brightness ranges. When there is no overlap, additional IQI(s) are to be used.

When performing CR or DR, ensure a measuring scale is utilized to serve as a length reference. The scale

is to be attached to the SPIP holder or DDA prior to exposure. As an alternative, when using SPIPs a transparent scale with opaque gradations may be placed on the SPIP prior to processing. In any case, the reference comparator cannot interfere with interpretation of the image.

Provide a work station monitor for evaluating images equipped with a display resolution with a pixel count

which is at least equal to the pixel count of the direct imaging plate.

Archive images using a reproducible electronic medium. Provide data file format and storage that comply with ASTM E2339, "Standard Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE)" format. Documented and prove the image archival method (at system installation). Include the image file nomenclature to enable the retrieval of images at a later date. Archived image files must maintain the bit depth and spatial resolution of the original image. Image data compression is not allowed. Preserve (store) the initial image presented by the CR or DR system without altering the original spatial resolution and pixel intensity. Preserve (store) the final image used for disposition when additional image processing is applied (excluding window/level and digital image zoom) to achieve the required image quality level. Store annotations made to the image in a manner which will not mask or hide diagnostic areas of the image.

S-55. (2521) SIDEWALK

The sidewalk may be curved and/or raised if necessary to save trees or other improvements as

determined by the Engineer.

Contraction joints shall be placed in the sidewalk at five-foot typical intervals and shall align with like

joints in the adjoining or neighboring work. Contraction joints shall be approximately 1/8” in width and

shall be cut to a depth of at least 1/3 the structure thickness, but not less than 3/4”.

Expansion joints shall be in sidewalk at the beginning and end of all radii, and shall align with like joints

in adjoining work. Expansion joints shall also be placed against all existing fixed objects.


S.P. 107-030-006

shall be backfilled with suitable material. The amount of concrete in place, but not completely

backfilled at any time, shall be limited to 4000 lineal feet. The backfill material behind the concrete

must be approved by the Engineer. Where sod or seed is to be installed, a minimum of four inches of

topsoil must be placed.

Concrete walk of each thickness will be measured by area and paid for at the Contract unit price per

square foot which shall be compensation in full for all costs incidental to construction, including (but

not limited to) excavation not included in roadway excavation quantities, granular base when required,

expansion fillers, and application of curing compound.

S-56. (2573) STORM DRAIN INLET PROTECTION

Storm sewer inlets shall be protected. Sediment Filter Sacks and Metal Basket Type options shall be

used. Other Engineer approved means may be used to prevent the entry of eroded material into the

storm sewer system; however, the Contractor must obtain approval for an alternate option before

installing any erosion control.

On streets where utility companies (eg: Xcel Energy, etc) are replacing facilities in conjunction with and

to necessitate work required under this Contract, inlet protection shall be installed, as approved by the

Engineer, before the utility company begins work and left in place until after work under this contract

is complete or removal is approved by the Engineer.

Storm Drain Inlet Protection, whether it be one of the above listed options or another Engineer

approved product, will be paid for under the lump sum Item 2575.601 “Erosion Control”. Lump sum

shall be considered to include all materials and labor as necessary to provide proper inlet protection

over the life of the contract regardless of quantities required. Under this provision, no measurement

will be made of any individual device or inlet location.

S-57. (2575) SODDING, TYPE SALT RESISTANT

Peat grown sod will not be accepted; only salt resistant sod shall be used on this Project. During the

pre-construction conference, the Contractor shall supply the name and contact information of their

sod subcontractor, certification from the grower stating the grass varieties contained in the sod and

the location where the sod will be harvested. The Engineer reserves the right to request a sample of

the sod to be used on the Project for approval prior to laying any sod.

Sod removal along with 4” of excavation necessary to install the sod and provide a neat edge will be

considered incidental work for which no direct compensation will be made. The 4” of select topsoil

borrow including material and placement required for sod shall be measured and paid for at the unit

bid price for 2105.526 “Select Topsoil Borrow” per cubic yard of material furnished, placed, and

wide or 2.5’ long. The Engineer, at his or her discretion, may reject a sodded area for the use of too

many small pieces

Landscaping shall be done in locations designated on the Plans or at other locations as directed by the

Engineer. The work shall include the replacing of all sod that has been disturbed or uprooted by other

phases of the Contract.

Prior to placing any topsoil, the slopes shall be cut uniformly, such that the finished sodded slope shall

conform to the designated section. The topsoil shall be raked and all lumps and irregularities

removed prior to placing the sod or seed. All sod and seed shall be placed on a minimum of four

inches of topsoil regardless of the previous condition of the lawn. Care shall be taken to insure that

the topsoil does not contaminate the subgrade or base of the street driving surface. Topsoil

remaining on the finished street shall be cleaned up immediately following the seeding or sodding

operation.

The Contractor shall install a “New Sod Notice” on each property where new sod is planted. The

notices will be furnished by the Engineer, and supplied to the Contractor to install. Each notice

consists of a 12” wire, flag type notice with a description of how to care for new sod. Care should be

taken while watering the new sod to not damage or displace the New Sod Notices. Installing the

notices shall be incidental work for which no direct compensation will be made.

The Contractor shall be responsible for maintaining sod in conformance with the requirements of

MnDOT 2575.
