What is the final QA responsibility of the CTI at the end of a delivery?

• A. Leave the site without verifying.
• B. Ensure all documentation is complete and accurate and that the load meets requirements or is properly rejected/disposed.
• C. Only check the temperature of the concrete.
• D. Submit a report but ignore discrepancies.

Answer: (B)

The essential idea is that the CTI’s final action after a delivery is to close out the QA process by making sure all paperwork is complete and accurate, and that the concrete delivered either meets the required specs or is properly rejected or disposed. This means reviewing the batch/ticket, delivery records, and any test or certification data to confirm everything aligns with the project’s requirements. If the load meets the specifications, the CTI confirms acceptance and documentation is filed for traceability. If it doesn’t, the CTI flags the discrepancies and ensures the load is rejected or disposed following procedure, so nonconforming material isn’t placed. This approach protects structural integrity and accountability, ensuring there’s a clear record of what was delivered, under what conditions, and how any issues were handled. It also prevents a scenario where only partial checks are done—such as just recording temperature or submitting a report without addressing problems.
