What is the inspector’s role in verifying the batch ticket after delivery?

• A. Confirm that the ticket matches the order, record the time of batching, and verify water added and materials meet the mix design and contract requirements.
• B. Confirm that the ticket matches the order and record the time of batching.
• C. Verify the ticket matches the contract color requirements.
• D. Notify the driver about speeding.

Answer: (A)

The key idea is that after delivery, the inspector must ensure the batch ticket accurately reflects what was ordered and that the materials and proportions used align with the approved mix design and contract. This means confirming the ticket matches the order, recording the exact time the batch was made, and verifying that the water added and the materials (cement, aggregates, admixtures, etc.) meet the mix design and contract requirements. Verifying the water added is essential because it directly influences the water-cement ratio and workability, which affect strength and durability, while checking materials ensures the batch uses the correct proportions and components specified in the design. If any of these elements don’t line up, there’s a risk of nonconforming concrete and traceability issues, so these checks are the core of proper QA at delivery. The other options omit one or more of these critical verification steps, focus on irrelevant factors like color, or involve duties outside the inspector’s scope (such as commenting on driving speed).
