On site, who determines what grade of material to be used for repair?

• A. Project Manager
• B. Safety Officer
• C. QA/QC
• D. Design Engineer

Answer: (C)

Quality and conformance on the project site are what determine the material grade used for a repair. QA/QC is responsible for ensuring that every material delivered and installed meets the project specifications, codes, and approved submittals. They review supplier certificates, mill test reports, and any required testing, then grant or withhold approval for use in the repair based on whether the material matches the required grade and is compatible with the existing structure. This on-site verification links design intent to field reality, making QA/QC the gatekeeper for material grade.

The project manager handles scheduling, budgeting, and procurement logistics, but doesn’t approve the technical grade of materials in use. The design engineer specifies the required grade in the design, but the on-site decision and acceptance come through QA/QC’s review and approval. The safety officer focuses on safety compliance and risk mitigation rather than selecting the material grade.
