Which activity best describes the CTI's role in QA during the delivery process?

• A. Coordinating with plant personnel on batch design.
• B. Confirming that load tickets, test results, and deviations are properly recorded and approved.
• C. Calculating the batch water content at the site.
• D. Selecting the aggregate source for the next batch.

Answer: (B)

The main idea is that the CTI’s QA role during delivery centers on ensuring documentation is complete, accurate, and properly approved. Verifying that load tickets, test results, and deviations are recorded and approved provides a traceable, auditable record of what was delivered, how it was tested, and how any issues were handled. This documentation flow is essential for proving the batch meets specifications and for accountability if problems arise. The other tasks fall outside this delivery QA gate: coordinating batch design is planning/engineering work, calculating batch water content is a field testing or QC measurement task, and selecting the aggregate source is a procurement/design decision.
