What regulation must each Agency Construction QA Program comply with?

The regulation that each Agency Construction QA Program must comply with is 23 CFR 637B. This regulation is part of the Code of Federal Regulations that outlines the requirements and standards for quality assurance programs in the construction industry, particularly those projects that receive federal funds. Compliance with 23 CFR 637B ensures that agencies uphold a systematic approach to monitoring and evaluating construction quality, which is critical for maintaining safety, reliability, and performance of transportation infrastructure.

The other options, while relevant in their respective contexts, do not serve as overarching regulations for construction quality assurance programs. ASTM C 150 pertains to the specifications for portland cement, ASCE 7 sets forth minimum design loads for buildings and other structures, and ACI 318 provides standards for structural concrete design. Each of these is crucial to specific aspects of construction but does not encompass the entirety of quality assurance program requirements that 23 CFR 637B addresses.
