What is the proper action if a batch ticket indicates a mismatch between the order and the batch in progress?

• A. Ignore and continue.
• B. Use the ticket from the previous batch.
• C. Notify the responsible parties and verify the ticket matches the order, batch time, and contents; segregation or stop placement per contract.
• D. Recalculate mix design on site.

Answer: (D)

When a batch ticket shows a mismatch between what was ordered and what’s in progress, the priority is to prevent placing the wrong material. The correct action is to notify the responsible parties and verify that the ticket matches the order, batch time, and contents; if there’s any discrepancy, segregate or stop placement per the contract. This ensures the concrete being produced and placed actually meets the specified order and keeps traceability for quality control and contractual compliance. Recalculating the mix design on site isn’t appropriate because the proportions are defined in the approved mix design and changes require formal review and reapproval; on-site adjustments could render the mix noncompliant. Ignoring the mismatch or using a previous ticket would bypass critical QA controls and risk producing nonconforming concrete.
