Construction Quality Control (CQC) is a planned system of routine inspections that is used to directly monitor and control the quality of a construction project.

Construction Quality Assurance (CQA) is independent of the CQC and includes inspections, verifications, audits, and evaluations of materials and workmanship necessary to determine and document the quality of a construction project.
