Print Date: July 2021 01400-1 \\BIL-FS\BIL-projects\26\21825-01\93Specs\01400_QC_QA.docx

PART 1 - GENERAL

DEFINITIONS:

Quality Control - planned and specific actions or operations necessary to produce a product that complies with the contract documents. Quality control consists of actions, inspections, sampling and testing necessary to ensure the work is in compliance with the contract documents and to control production and construction processes. Quality control is keyed to the construction sequence to quickly determine when the work is out of compliance with the contract documents and to respond to correct the situation and bring the work into compliance. Quality control is the responsibility of the CONTRACTOR.

Quality Assurance – planned and systematic observations, testing and actions to verify the work complies with the contract documents. Quality assurance includes oversight of the

CONTRACTOR’s quality control, verifying the results of the CONTRACTOR’s testing and additional assurance sampling and testing.

Verification/Compliance Testing – sampling and testing which is carried out independent of the CONTRACTOR’s quality control testing to confirm/verify the work complies with the contract documents. The frequency of verification/compliance testing will be determined by the
