Section 106. - Acceptance of Work

106.01_nat_us_07_31_2007

106.01 Conformity with Contract Requirements.

Delete Subsection 106.01 and substitute the following:

Follow the requirements of FAR Clause 52.246-12 Inspection of Construction.

References to standard test methods of AASHTO, ASTM, GSA, and other recognized standard authorities refer to the methods in effect on the date of solicitation for bids.

Perform all work to the lines, grades, cross-sections, dimensions, and processes or material requirements shown on the plans or specified in the contract.

Incorporate manufactured materials into the work according to the manufacturer’s recommendations or to these specifications, whichever is more stringent.

Plan dimensions and contract specification values are the values to be strived for and complied with as the design values from which any deviations are allowed. Perform work and provide material that is uniform in character and reasonably close to the prescribed value or within the specified tolerance range. The purpose of a tolerance range is to accommodate occasional minor variations from the median zone that are unavoidable for practical reasons.

When standard manufactured items are specified (such as fence, wire, plates, rolled shapes, pipe conduits, etc., that are identified by gauge, unit mass, section dimensions, etc.), the identification will be considered to be nominal masses or dimensions. Unless specific contract tolerances are noted, established manufacturing tolerances will be accepted.

The Government may inspect, sample, or test all work at any time before final acceptance of the project. When the Government tests work, copies of test reports are furnished to the Contractor upon request. Government tests may or may not be performed at the work site. If Contractor testing and inspection is verified by the Government, the Contractor’s results may be used by the

Government to evaluate work for acceptance. Do not rely on the availability of Government test results for process control.

Acceptable work conforming to the contract will be paid for at the contract unit bid price. Four methods of determining conformity and accepting work are described in Subsections 106.02 to

106.05 inclusive. The primary method of acceptance is specified in each Section of work.

However, work may be rejected at any time it is found by any of the methods not to comply with the contract.

Remove and replace work that does not conform to the contract, or to prevailing industry standards where no specific contract requirements are noted, at no cost to the Government.

(a) Disputing Government test results. If the accuracy of Government test results is disputed, promptly inform the CO. If the dispute is unresolved after reasonable steps are taken to resolve the dispute, further evaluation may be obtained by written request.

AG-0261-S-13-0055 Shingle Hall Attachment 6 Page 12 of 55

Include a narrative describing the dispute and a proposed resolution protocol that addresses the following:

(1) Sampling method;

(2) Number of samples;

(3) Sample transport;

(4) Test procedures;

(5) Testing laboratories;

(6) Reporting;

(7) Estimated time and costs; and

(8) Validation process.

If the evaluation requires additional sampling or testing be performed, mutually agree with the Government on witnessing procedures and on sampling and testing by a third party laboratory. Use a third party laboratory accredited by the AASHTO accreditation program.

Provide proof of the laboratory’s accreditation for the test procedures to be used. Do not use the same laboratory that produced the disputed Government test results or that produced the test results used as a basis for the dispute.

The CO will review the proposed resolution protocol and may modify it before final approval and execution.

The Government will use the approved resolution protocol test results to determine the validity of the disputed testing. If the Government test results are validated, the Contractor will be responsible for all costs associated with developing and performing the resolution protocol. If the Government test results are not validated, the Government will be responsible for all costs associated with developing and performing the resolution protocol.

If the validity of the Government test results cannot be determined, the Contractor and

Government will equally share all costs associated with developing and carrying out the resolution protocol.

(b) Alternatives to removing and replacing non-conforming work. As an alternative to removal and replacement, the Contractor may submit a written request to:

(1) Have the work accepted at a reduced price; or

(2) Be given permission to perform corrective measures to bring the work into conformity.

The request must contain supporting rationale and documentation. Include references or data justifying the proposal based on an evaluation of test results, effect on service life, value of material or work, quality, aesthetics, and other tangible engineering basis. The CO will determine disposition of the nonconforming work.

Add the following:

The Contractor is solely responsible for all spills or leaks that occur during the performance of this contract. Clean up spills or leaks to the satisfaction of the CO and in a manner that complies with Federal, state, and local laws and regulations.

Design and locate equipment repair shops, stationary refueling sites, or other facilities to minimize the potential and impacts of hazardous material spills on Government land.

Before beginning any work, submit a Hazardous Spill Plan. List actions to be taken in the event of a spill. Incorporate preventive measures to be taken, such as the location of mobile refueling facilities, storage and handling of hazardous materials, and similar information.

Describe how the contractor will comply with the following three methods to minimize fuel/oil leakage from construction equipment into the stream channel. Include the following:

i. Clean all equipment used for in-stream work so that it is free of external oil, grease, dirt and mud, and repair leaks, prior to arriving at the project site. All equipment will be inspected by the Contracting Officer’s Representative before unloading at site. Correct any leaks or accumulations of grease before entering streams or areas that drain directly to streams or wetlands.

ii. Fuel and service equipment used for in-stream or riparian work (including chainsaws and other hand power tools) in an established staging area (site-specifically designated by CO). When not in use, store vehicles in the designated staging area.

The staging area should be in an area that will not deliver fuel, oil, etc., to streams.

iii. Oil-absorbing floating booms, and other equipment such as pads and absorbent

“peanuts” appropriate for the size of the stream, shall be available on site during all

AG-0261-S-13-0055 Shingle Hall Attachment 6 Page 14 of 55 phases of construction. For very small streams with few pools or slack water, booms may not be effective. More pads and straw bales to anchor booms may be necessary.

Place booms in a location that facilitates an immediate response to potential petroleum leakage.

Immediately notify the CO of all hazardous material spills. Provide a written narrative report no later than 24 hours after the initial report, and include the following:

Description of the item spilled (including identity, quantity, manifest number, and other identifying information).

Whether amount spilled is EPA- or State-reportable, and if so whether it was reported, and to whom. Follow Federal and Idaho State regulations regarding spills. Report any spills resulting in a detectable sheen on water to the EPA National Response Center (1-

800-424-8802). Report any spills over 25 gallons to the IDEQ (1-800-632-800), and initiate cleanup within 24 hours of the spill.

Exact time and location of spill including a description of the area involved.

Containment procedures.

Summary of any communications the Contractor had with news media, Federal, State and local regulatory agencies and officials, or Forest Service officials.

Description of clean-up procedures employed or to be employed at the site, including final disposition and disposal location of spill residue.

When available, provide copies of all spill-related clean-up and closure documentation and correspondence from regulatory agencies.

157.03 General

Delete the first two paragraphs and replace with the following:

Submit an Erosion Control Plan detailing permanent and temporary erosion-control measures to minimize erosion and sedimentation during and after construction, in accordance with the plans and storm-water permits. Do not modify the type, size, or location of any control or practice without approval. Submit the erosion-control plan proposal at least 7 days before operations begin to the CO for approval.

Reflect in the Erosion Control Plan special concerns and measures necessary to protect resources and government improvements. Include:

1. The construction activities and sequence of implementation relating to specific erosion control measures.

2. The location and type of permanent controls to be implemented during construction.

3. The location and type of temporary controls to be implemented during construction.

4. For work in stream channels with running water, a detailed dewatering plan. Convey water around the construction area during the operating season and higher flows in the event of a storm. Notify the COR at least 10 days in advance of any stream work or dewatering.

The COR will notify the District Fish biologist who will be available during dewatering to move fish from the dewatering area using a combination of dip-netting and electrofishing.

Schedule the start of dewatering to occur in the mid-morning, so the fish crew will have the afternoon to remove the fish. After the COR approves the stream simulation placement, re-water the area slowly to help the movement of fish.

157.03_0510_11_10_2004

AG-0261-S-13-0055 Shingle Hall Attachment 6 Page 24 of 55

In perennial channels, pre-wash the reconstructed stream channel into a reach equipped with sediment-capture devices such as Sedimat, prior to reintroduction of flow to the stream.

Re-water the construction site slowly to prevent loss of surface water downstream as the construction-site streambed absorbs water and to minimize a sudden increase in turbidity.

Use in-channel sediment-abatement barriers such as Sedimat to capture sediment that is liberated during re-watering of dewatered channels. Clean out and remove barriers, and dispose of captured sediment so it is not reintroduced into stream channels. Maintain such barriers throughout the related construction and remove only when construction is complete and erosion control is assured.

5. The location of each temporary stockpile site for the excavated material, and location of erosion control measures to prevent sediment from washing off of stockpile.

157.03_R04F12_03_07_2012

Add to the third paragraph:

Upon completion of construction at the site, remove all temporary dewatering materials and equipment from Government property. This includes items such as pumps, pipes and hoses, and sandbags.

Adhere to the following practices:

a) In order to protect aquatic organisms, install screens on the intake of pumps with opening of 3/32 inch.

b) Centrifugal pumps used for removing water from structure excavation (if needed) shall sit in a secondary spill container with sufficient capacity to contain the quantity of fuel in the pump fuel tank.

c) Construct the Dewatering and Sediment Control according to the Contractor’s approved plan.

d) Maintain the roads and stockpiles of material in a manner that prevents direct entry of sediment into the stream, by either preventing the erosion of sediments or collecting the sediments before it reaches the stream.

e) Construct permanent and temporary control features to intercept sediments. A settling basin will be constructed, or a portable one used, that is able to handle the volume of water anticipated, and that provides filtering capability. Dewatering of the excavation site, (of ground water from the excavation) will be done by pumping water to the settling basin, and the basin shall be cleaned out when full of sediments.

f) Any sanitation facilities established by the Contractor shall be located as designated by the CO.
