106 - Acceptance of Work

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 restrictive.

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. Three methods of determining conformity and accepting work are described in Subsections 106.02 to

106.04 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.

106.05 Statistical Evaluation of Work and Determination of Pay Factor (Value of Work).

Replace the entire section with the following:

Statistical evaluation of the work will not be required. All specifications referring to this Subsection shall instead be referred to Subsections 106.02 through 106.04 as appropriate for the work performed.

Section 156.—PUBLIC TRAFFIC

156.01 Description

This work consists of controlling and protecting public traffic adjacent to and within the project.

156.02 Material

Conform to the “Manual on Uniform Traffic Control Devices” (MUTCD) and applicable Subsections within the following Sections:

Permanent Traffic Control 633 Temporary Traffic Control 635 Traffic Signing and Marking Materials 718

156.03 Roads to be Constructed.

Unless otherwise indicated within the plans or specifications, keep existing roads open to all traffic during road improvement work, and maintain them in a condition that will adequately accommodate traffic. Perform no work that interferes or conflicts with traffic or existing access to the roadway surface until a plan for the satisfactory handling of traffic has been approved by the CO.

Specific requirements for temporary closures, detours, part-width construction, and access to adjacent or intersecting facilities will be indicated within the plans or specifications. Post construction signs and traffic control devices in conformance with the MUTCD and the project requirements. Do not proceed with work on the project until all required signs and barricades are in place and approved by the CO.

Before shutting down any operations, take all necessary precautions to prevent damage to the project, such as temporary detours, approaches, crossings, or intersections; and provide for normal drainage and minimization of erosion. Leave all travel ways in a condition suitable for traffic.

When indicated on the plans or described in the specifications, road segments may be closed to all traffic during the period(s) when construction is in progress. If any of the listed roads are to be closed during construction operations, give the CO at least 14 days advance notice.

156.04 Maintaining Roadways during Work.

Do not construct detours outside of the clearing limits or use alternate route detours without the approval of the CO.

Unless otherwise indicated within the plans or specifications, keep existing roads open to all traffic during road improvement work, and maintain them in a condition that will adequately accommodate traffic. Perform no work that interferes or conflicts with traffic or existing access to the roadway surface until a “Travel Management Safety Plan” for the satisfactory handling of traffic has been approved by the CO. Submit the plan to the CO for approval at least 14 days prior to starting work. The plan shall address how the Contractor intends to perform hauling operations to the site while allowing for public traffic on the same access road.

157 – Soil Erosion Control

157.03 General.

Delete the entire subsection and replace with the following:

Prior to the start of construction, submit a written plan that provides permanent and temporary erosion control measures to minimize erosion and sedimentation during and after construction.

Do not begin work until the necessary controls for that particular phase of work have been implemented. Do not modify the type, size, or location of any control. An alternate erosion control plan with all necessary permits may be submitted 30 days before intended use.

Incorporate all permanent erosion control features into the project at the earliest practicable time, as outlined in the approved plan.

When erosion control measures are not functioning as intended, immediately take corrective action.

157.05 Filter Barriers.

Silt fence shall be straw wattles, logs, or rolls.

157.06 Sediment Retention Structures.

(b)Sediment basins.

Add the following:

Sediment basins (when required) may be excavated or geotextile sediment bag(s) may be used in accordance SCR 714.03. The size of geotextile sediment bag shall be 15’x 15’. Install geotextile sediment bag(s) on a slope so incoming water flows downhill through the bag without creating more erosion. Strap the neck of the geotextile bag tightly to the discharge hose. The outlet of the geotextile sediment bag(s) shall have riprap over geotextile fabric to prevent erosion.

Sediment basins and geotextile sediment bag(s) shall be periodically relocated for construction operations or as directed by the CO. The contractor shall obtain data from the geotextile sediment bag and pump manufacturers to ensure they are compatible (i.e., the pump(s) providing the flow to the geotextile sediment bags does not produce a higher flow rate than the maximum rate which the geotextile sediment bag can filter and discharge). To increase the efficiency of filtration, the contractor may place the geotextile sediment bag(s) on an aggregate (crushed rock) base or hay bale bed to maximize water flow through the surface area of the bag. The aggregate base or hay bales, if installed, shall be removed with any relocation of the geotextile sediment bag or from National Forest lands upon conclusion of the dewatering operations. Hay bales shall be certified weed free materials. Sediment basin areas shall be reclaimed with grading, seeding and mulch, as required.

The geotextile sediment bag is full when it no longer can efficiently filter sediment or pass water at a reasonable rate. Flow rates will vary depending on the size of the geotextile bag, the type and amount of sediment discharged into the geotextile bag, the type of ground, rock or other substance under the bag and the degree of the slope on which the bag lies. Under most circumstances geotextile bag may accommodate flow rates of 1500 gallons per minute. Use of excessive flow rates or overfilling geotextile sediment bag with sediment may cause ruptures of the bags or failure of the hose attachment straps. Ruptured or disposed bags shall be replaced by the Contractor at no additional expense to the Government. Dispose geotextile bags as approved by the CO, off National Forest lands and in accordance with Federal, State, and Local laws.

157.09 Diversions

Add the following:

For diversion requirements, refer to Special Contract Requirement 208.08.

157.10 Waterway and Slope Protection and Stabilization.

(e) Temporary slope drains.

Replace with the following:

If dewatering is required, the pumped water discharge from dewatering activities shall not be allowed to flow overland back into the creek. Pumped water shall be treated by a sediment basin or geotextile sediment bag.
