Which statement best describes the difference between Quality Control and Quality Assurance in USACE CQM?

• A. QC is the owner’s verification of work, and QA is contractor daily checks.
• B. QC is the contractor’s day-to-day checks to ensure work meets specs; QA is the owner/USACE verification of QC results and processes.
• C. QC and QA are the same functions performed by the contractor.
• D. QA replaces QC in the project once initial inspections are complete.

Answer: (B)

In USACE CQM, the important distinction is who performs the checks and what they verify. The contractor conducts quality control as daily checks to ensure work meets the contract specifications. This includes on-site inspections, testing, and documentation of workmanship and material quality to confirm the work is being done correctly by the contractor. The owner/USACE provides quality assurance by independently verifying the QC results and the processes used to achieve quality. QA reviews QC records, audits QC activities, and verifies that the overall quality management system is functioning properly, ensuring that the contractor’s results are reliable and that the project meets contract requirements. So, QC is the contractor’s day-to-day verification of workmanship against specs, while QA is the owner’s independent verification of those QC results and the QC processes. The other statements misplace roles, claim they are the same, or suggest QA replaces QC after initial inspections, which doesn’t reflect how QC and QA work together in the CQM framework.
