What records should be maintained by the CTI for quality control?

• A. A project schedule and delivery notes.
• B. Test results and calibration worksheets only.
• C. Load tickets, test results (slump, temperature, air content), calibration records, and any deviations or corrective actions.
• D. No records are required.

Answer: (C)

Quality control hinges on keeping a complete, verifiable trail of what was produced, how it was tested, and what was done to address anything that didn’t meet requirements. For a CTI, that means keeping load tickets that link each delivery to its batch and source, so you can trace the concrete to its origin. It also means recording test results for every delivery—like slump, placement temperature, and air content—so you can verify the concrete properties at the time it’s placed. Calibration records for the testing equipment are essential too; they prove that the measurements you rely on are accurate and current. Finally, documenting any deviations from specifications and the corrective actions taken provides accountability and a record for preventing recurrence. While delivery notes or schedules have value, they don’t capture the critical quality measurements, the equipment accuracy, or the actions taken when issues arise. No records at all would leave QC untraceable and unsupported.
