Which two parts make up the Earthwork Record System under contract?

• A. QC and Verification
• B. Design and Verification
• C. QA and QC
• D. Planning and Audit

Answer: (A)

The main idea here is that the Earthwork Record System under a contract relies on two complementary functions: quality control during execution and a separate verification step after or during work to confirm accuracy and compliance.

Quality control covers the on-site checks, tests, and procedures used as earthwork is being done. It includes ensuring materials meet specifications, monitoring compaction and moisture, checking equipment and methods, and keeping accurate, contemporaneous records of how work is performed. This keeps errors from propagating and helps guide the work to meet contract requirements as it progresses.

Verification is the independent review that checks the QC data and final measurements against the contract documents. It validates that the recorded volumes, elevations, compaction results, and other relevant data are correct and complete, providing an objective confirmation that the earthwork records reflect what was actually built and complies with the contract terms.

Other options mix activities that aren’t the established pair for this system. Design or planning-related terms aren’t describing the two-part record system, and while QA is a broader concept, the paired emphasis in this context is on quality control during construction and verification of the records.
