PART 9 – QUALITY REQUIREMENTS

9.1 DESCRIPTION

A. This section includes administrative and procedural requirements for quality assurance and quality control.

B. Testing and inspecting services are required to verify compliance with requirements specified as indicated. These services do not relieve Contractor of responsibility for compliance with the Contract Document requirements, and do not limit the Contractor’s quality control procedures that facilitate compliance with Contract Document requirements.

9.2 CONFLICTING REQUIREMENTS

A. General: If compliance with two or more standards is specified and the standards establish different or conflicting requirements for minimum quantities or quality levels, comply with the most stringent requirement. Refer uncertainties and requirements that are different, but apparently equal, to CO for a decision before proceeding.

B. Minimum Quantity or Quality Levels: The quantity or quality level shown or specified shall be the minimum provided or performed. The actual installation may comply exactly with the minimum quantity or quality specified, or it may exceed the minimum with reasonable limits. To comply with these requirements, indicated numeric values are minimum or maximum, as appropriate, for the context of requirements. Refer uncertainties to CO for a decision before proceeding.

9.3 QUALITY CONTROL

010150-20

A. General: The quality of all work shall be the responsibility of the Contractor. Testing shall be the responsibility of an independent testing laboratory.

B. Inspect and test all work often enough to ensure that the quality of materials, workmanship, construction, finish, and functional performance is in compliance with applicable specifications and drawings. Failure to test often enough does not relieve Contractor of responsibility of testing or redoing work to accommodate testing.

C. Contractor Responsibilities: Unless otherwise indicated, provide quality-control services specified and required by authorities having jurisdiction. Notify CO at least two (2) working days in advance for opportunity to witness test.

D. Manufacturer's Field Services: Where indicated, engage a factory-authorized service representative to inspect field-assembled components and equipment installation, including service connections. Report results in writing.

E. Retesting/Reinspecting: Regardless of whether original tests or inspections were Contractor's responsibility, provide quality-control services, including retesting and reinspecting, for construction that revised or replaced Work that failed to comply with requirements established by the Contract Documents.

F. Off-Site Control: Items that are fabricated or assembled off-site shall be inspected for quality control at the place of fabrication. Provide documentation of fabrication.

G. Enforcement: The Contractor shall stop work on any item or feature pending satisfactory correction of any deficiency noted by the quality control staff, testing agency, or the CO.

9.4 REPAIR AND PROTECTION

A. General: On completion of testing, inspecting, sample taking, and similar services, repair damaged construction and restore substrates and finishes.

B. Restore patched areas and extend restoration into adjoining areas in a manner that eliminates evidence of patching.
