Florida DOT Concrete Batchman/Operator Practice Exam

Who should sign for the amount of water added at the job site?

1. The concrete batch plant operator

2. The job site supervisor

3. The contractor's representative

4. The mixer truck driver

The correct answer is: The contractor's representative

The contractor's representative is responsible for signing for the amount of water added at the job site. This practice ensures accountability and accurate documentation of materials used in the concrete mix. The contractor's representative is typically in charge of overseeing the project and ensuring that all specifications, including water content, adhere to project requirements and standards. Signing off on the amount of water is crucial because water significantly affects the quality and strength of the final concrete product. Accurate records help in maintaining consistency and in addressing any future questions regarding the mix design or performance of the concrete used. While the other roles, such as the concrete batch plant operator, job site supervisor, or mixer truck driver, have important responsibilities in the concrete placement process, the contractor's representative is specifically tasked with managing the contract and ensuring that all aspects of material usage, including water, are documented properly.
