106 - Acceptance of Work

106.01 Conformity with Contract Requirements

Delete the entire subsection and replace with the following:

Pike & San Isabel NF’s Roads Construction IDIQ Page 7 of 33

Attachment J.1 – Standard, Supplemental, and Special Project Specifications Page 7 of 33

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 strict.

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, repair, or replace work that does not conform to the contract, or to prevailing industry standards where no specific contract requirements are noted. Removing, repairing, or replacing work; providing temporary traffic control; and any other related work to accomplish conformity will be 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.

Pike & San Isabel NF’s Roads Construction IDIQ Page 8 of 33

Attachment J.1 – Standard, Supplemental, and Special Project Specifications Page 8 of 33

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.

106.02 Visual Inspection

Delete the entire subsection and replace with the following:

Acceptance is based on visual inspection of the work for compliance with the specific contract requirements. Use prevailing industry standards in the absence of specific contract requirements or tolerances.

Level and smooth each embankment layer before placing the next layers. Operate hauling and spreading equipment uniformly over the full width of each layer. Construct a solid embankment with adequate compaction by working smaller rock and fines in with the larger rocks to fill the voids, and by operating hauling and spreading equipment uniformly over the full width of each layer as the embankment is constructed.

(e) Layer Placement (Roller Compaction) Method. Place material by end dumping to the minimum depth needed for operation of spreading equipment. Adjust the moisture content of the material to obtain a mass that will not visibly deflect under the load of the hauling and spreading equipment. Operate compaction equipment over the full width of each layer until visible deformation of the layer ceases or, when a sheepsfoot roller is used, the roller “walks out” of the layer.

(2) Method B. Roll the roadbed to break down rocky material. Roll a minimum of five full-width passes, or until visual displacement ceases, with a vibratory grid roller or equivalent with a minimum mass of 8 tons.

(3) Method C. Tractor finish work by spreading the excavation for roads designated as Construction Tolerance Class K, L, or M. Eliminate rock berms that may form during embankment construction with a tractor finish.

211.01 Description

Delete this subsection and replace with the following:

This work consists of the reclamation of roadways by the removal of culverts; construction of waterbars and leadoff ditches; restoration of stream channels; and seeding, fertilizing, and mulching of all disturbed areas. This work may include necessary diverting of live streams, pumping, bailing, draining, sheeting, bracing, and miscellaneous items required for execution of the work. Additionally, survey stakes depicting work locations may need to be re-established using original survey notes and/or plans.

Roadway reclamation methods are designated as follows:

(a) Method 1. Fill ditches and restore the roadway to approximate original ground contour or shape to blend with the terrain. Before placing embankment, loosen the roadbed by ripping or scarifying to the depth of 12 inches. Pull all embankments and apply the material to contour or fill ditches; or haul it to designated areas. Construct waterbars as shown on the plans. Scatter any available slash on obliterated roadway. Keep excavated material within the original roadway limits unless otherwise shown on the plans.

(b) Method 2. Shape the roadway to drain water. Fill ditches, outslope the roadbed and loosen the roadbed by ripping or scarifying to the depth of 12 inches to provide a seedbed and promote establishment of vegetation. Scatter any available slash on obliterated roadway.

Construct waterbars as shown on the plans. Effectively close the road by method shown on plans.
