106 - Acceptance of Work

106.01_nat_12_15_2004

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 stricter.

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.

Crack seal and fill only when internal pavement temperatures are between 36 and 68 °F the road surface is dry, there is no frost in the road section, and the weather is not foggy or rainy.

Heat, mix, and apply the crack sealing and filling materials as recommended by the sealant manufacturer. Submit a copy of the manufacture’s recommendations to the CO prior to the start of work.

Prepare cracks between 1/4 inch and 1 inch and apply sealant by one of the following methods:

· Crack Sealing - Rout and clean all cracks between 1/4 inch and 1 inch wide. Rout cracks to produce a reservoir with straight ½ inch vertical walls and a 1 1/2 inch wide flat bottom. Use a low-modulus rubberized asphalt. Completely fill the routed cross section flush with the pavement surface.

· Crack Filling - Clean the crack between 1/4 inch and 1 inch wide. Prepare cracks to a depth of at least three times the crack width. Ensure crack sealing materials penetrates more than twice the crack width.

For cracks between 1/2 inch and 1 inch where sealant penetrates more than two times the crack width, use a backer rod.

For cracks with a width greater than or equal to 1 inch, clean and fill flush to the existing surface with asphalt mix according to Section 401, 402, 403, 404, or 417.

For cracks less than ¼ inch wide, clean and fill with CSS-1, SS-1, or joint sealant. Apply a sealant band less than 2 inches over the crack, such that the crack is centered under the band. Submit a copy of, and adhere to, the manufacture’s recommendations for heating and applying the joint sealant.

Clean cracks with a stream of air to remove all dirt, dust, or deleterious matter adhering to the crack walls or remaining in the crack cavity so that the crack is clean and dry when the sealant is applied. Blow or brush dry material off the pavement surface. Avoid damage to the adjacent pavement.

Use approved methods to protect all seal materials from being picked up by traffic. Treat seal material tracked onto the road surface as directed by the CO.
