Who is responsible for performing moisture tests before the start of operations each day?

The responsibility for performing moisture tests before the start of operations each day falls to the contractor's certified concrete technician. This role is specialized and trained in the technical aspects of concrete mixing and applications, which includes understanding how moisture levels can impact the quality of the concrete. The technician ensures that the moisture content is within acceptable limits to prevent issues like inadequate bonding, improper curing, or even structural weaknesses. By conducting these tests daily, the technician helps maintain quality control and adherence to specifications, which is crucial for the integrity and longevity of the concrete work.

Other roles like the project manager, site engineer, or quality control supervisor may oversee or coordinate various aspects of the construction project, but the specific expertise and responsibility for moisture testing lie with the certified concrete technician. This distinction underscores the importance of specialized training in achieving optimal results in concrete operations.
