Florida DOT Concrete Batchman/Operator Practice Exam

Where must batch adjustments be noted?

1. On the concrete mixing log

2. In the field book

3. Concrete delivery ticket

4. On the contractor's invoice

The correct answer is: Concrete delivery ticket

The correct answer, which states that batch adjustments must be noted on the concrete delivery ticket, aligns with industry best practices and regulatory requirements. The concrete delivery ticket serves as a formal record of the materials delivered to a job site, and it is essential for ensuring proper communication between the supplier and the contractor. Noting adjustments on this document provides a clear and immediate account of any changes made to the original mix design or batch proportions at the time of delivery. Incorporating batch adjustments into the delivery ticket is critical for maintaining quality control and accountability, as it allows for accurate tracking of the materials used in the concrete mix. This transparency is important for project documentation and can help resolve potential discrepancies that may arise later concerning the quality or specifications of the delivered concrete. The other options, while they may also contain valuable information, do not serve the same purpose as the concrete delivery ticket concerning official documentation of batch adjustments. The concrete mixing log and field book may be used for internal records, but they do not provide the same level of immediate accountability. The contractor's invoice is typically concerned with financial transactions and does not focus specifically on the details of batch adjustments.
