On site, which group determines the material grade to be used for repair?

• A. QA/QC
• B. Project Team
• C. Safety
• D. Design

Answer: (A)

Quality control on site is the key: the group that ensures the materials used for repair meet the project’s specifications and standards. They review the repair drawings and material specs, verify that the chosen material grade matches what the design requires, check supplier certificates and test results, and authorize the material for use. They also overseeStorage, handling, and testing processes and address any nonconforming material. The grade requirement typically comes from design, but it’s QA/QC that enforces and approves the exact material used on site, ensuring it complies with codes and project criteria. Safety provides the safe-work rules, and the project team coordinates overall execution, while the design defines what grade is needed; QA/QC ensures that the correct grade is actually applied in the repair.
