Florida DOT Concrete Batchman/Operator Practice Exam

Who must check the accuracy of weighing or measuring devices prior to concrete production?

1. The concrete batch operator

2. A qualified representative of a scale company registered with the Bureau of Weights and Measures

3. Government inspectors

4. The project engineer

The correct answer is: A qualified representative of a scale company registered with the Bureau of Weights and Measures

The correct answer involves the requirement for a qualified representative of a scale company registered with the Bureau of Weights and Measures to check the accuracy of weighing or measuring devices before concrete production. This process ensures that the equipment used in batching is calibrated accurately, which is critical for maintaining the integrity and quality of the concrete being produced. Having a qualified representative perform these checks is essential because they possess the expertise needed to ensure compliance with established regulations and standards. This step helps to prevent issues related to incorrect material ratios, which can compromise the concrete's strength and durability. Other individuals, while they may be involved in the overall process, such as a concrete batch operator, government inspectors, or a project engineer, typically do not have the specialized training or official authorization required to conduct these accuracy checks. Their roles might focus on oversight, quality assurance, or operational management, rather than the technical calibration and verification of measuring equipment.
