8.0 Quality Control Plan

The Contractor shall submit to the CO, a Quality Control Plan (QCP) as part of their proposal that will detail the methods the Contractor will use to perform self-inspection to ensure the requirements of this contract are performed in accordance with the contract documents. The QCP shall at a minimum record the reference pay item, location, frequency, type of test and resulting outcome. QCPs shall be submitted with the Accomplishment Report and no payment will be made prior to receipt of these records and acceptance of the work performed.

At a minimum, the QCP shall contain:

• Inspection System. An inspection system must cover all of the services listed in the contract documents.

It must specify the work items to be inspected on either a scheduled or unscheduled basis, how often inspections will be accomplished, and the title of the individual(s) who will perform the inspection. The inspection system must provide for a written record of inspections and results.

• Methods. Identify the proposed methods for identifying and preventing defects before the level of performance becomes unacceptable.

Records. The contractor shall maintain on-site records of all inspections and necessary corrective action(s) taken. This documentation shall be furnished at the time payment is requested, or when requested by the Contracting Officer’s Representative during the term of the contract. Project inspectors reserve the right to check contractor’s Quality Control Inspections at any time during the life of the project.

9.0 Government Quality Assurance

The Government will monitor progress to ensure that the Contractor is providing the quality promised in their QC Plan and that work meets performance standards. Visual observation may be used. The Government reserves the right, if deemed necessary to ensure compliance with the contract, to make random or 100% full inspections of the work. Each road and culvert will be inspected separately.

Government inspections will be documented on Daily Diaries and placed in the contract file. If work in part of an area is not acceptable, a Notice of Non-Compliance will be issued to the Contractor. See attached for sample of form. The CO may issue other cure notices if work is not being performed in a timely manner or does not comply with contract specifications.

Upon completion of a culvert or road and notification by the Contractor, the COR or designated Inspector shall make an overall inspection of that/those culverts/roads. If a need for remedial work prior to acceptance is reflected by the COR/Inspector`s inspection, such remedial work will be performed before the Contractor moves to the next area(s). If the inspection results in acceptance of the area, the Contractor may immediately proceed with work on the next area(s).

Government inspections are for the sole benefit of the Government and do not:

• Relieve the Contractor of responsibility for providing adequate quality control measures;

• Relieve the Contractor of responsibility for damage to or loss of the material before acceptance;

• Constitute or imply acceptance; or

• Affect the continuing rights of the Government after acceptance of the completed work.

10.0 Contractor’s Key Personnel
