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.

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-15-0059

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.

Add the following:

This work includes washing and treating construction equipment and vehicles necessary for equipment transport to remove seeds, plants, and plant fragments before the equipment is used on Forest Service lands.

Wash the sides, tops, and undercarriages of all construction equipment with a high-pressure washing system. Perform all work at a location designated on the plans or other locations approved in writing. Provide the CO with an opportunity to monitor the washing and inspection.

Remove all seeds, plants, plant fragments, dirt, and debris from the construction equipment.

Only equipment cleaned and inspected will be allowed to operate within the project area. All subsequent move-ins of equipment to the project area will be treated in the same manner as the initial move-in. This requirement does not apply to cars, pickup trucks, dump trucks, and other vehicles that regularly travel between the construction site and areas off the National Forest.

Equipment will be considered free of soil, seed, and other such debris when a visual inspection does not disclose such material. Disassembly of equipment or components, or the need for specialized inspection tools, is not required.

Notify the CO in writing at least 7 days before moving any construction equipment onto the

National Forest, and at least 24 hours before changing locations within the project area. Include an agreed-upon location where the equipment will be available for inspection. Inspection is required after every cleaning.

Use methods of cleaning and locations for cleaning approved by the C.O.

For work on National Forest System lands, use a washing system that traps all wash water and either stores it for removal from National Forest System lands or recycles the water for continued use. If the equipment recycles the water, provide adequate filters for seed removal. Dispose of the filter material and removed seeds offsite in a legal and approved manner. Do not mix soaps, detergents, or other chemicals with the wash water.

For work at a commercial washing facility, use an approved facility.

New infestations of noxious weeds of concern to Forest Service and identified by either

Contractor or Forest Service, on the Project Area or on the haul route, shall be promptly reported to the other party. Contractor and Forest Service will agree on treatment methods to reduce or stop the spread of noxious weeds when new infestations are found. A current list of noxious weeds of concern to Forest Service is available at each Forest Service office. A list of known infestations along roads to be reconstructed will be available to the Contractor before work begins.

Remove the turbid water by pumping to an infiltration area, or letting the sediment settle in the settling pond.

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.

6. Keep a supply of erosion-control materials (e.g. silt fence, straw bales, and/or straw wattles) on hand to respond to sediment emergencies. Use only sterile straw or certified

“weed-free” straw to prevent introduction of noxious weeds.

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, insure that drafting hoses are fitted with screens with a 3/32 inch mesh and the appropriate surface area for the pump to achieve a mazimum water velocity of 0.4 ft/ sec at the screen surface, consistent with NOAA guidelines.

b) Centrifugal pumps used for drafting water from live streams or 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

AG-0261-S-15-0059

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.

g) Cease all project operations, except efforts to minimize storm or high-flow erosion, under precipitation and high-flow conditions that result in uncontrollable erosion in the construction area.

157.04 Controls and Limitations on Work.

Add the following to the second paragraph:

Place temporary erosion-control measures at the end of each day’s operation if greater than 30 percent chance of rainfall is predicted. Earthwork operations may be temporarily suspended by the CO if significant rainfall is forecast.

157.08 Water Crossings.

When there is water flowing through a channel crossing, dewater that site by rerouting the flow around the site before and during excavation and embankment operations that have the potential for sediment delivery to the live stream. If pumps are used, install screens on pump intakes with maximum openings of 3/32 inch to protect aquatic organisms.
