Where should the finisher's request to add water to the concrete truck on site be addressed?

• A. On the jobsite
• B. The preconstruction conference
• C. During the daily production meeting
• D. At project closeout

Answer: (B)

Field adjustments to the concrete mix, such as adding water, must be handled through the project’s approved change process because they directly affect slump, air content, strength, and durability. The preconstruction conference is where the team sets how on-site modifications to materials will be addressed, who has authority to approve them, and how they are documented and tested. This ensures any water addition is reviewed against the approved mix design or a formal change order, with QC checks in place. Addressing such a request on the jobsite or in routine daily meetings can lead to unrecorded changes and quality or specification issues, and waiting until project closeout is far too late to ensure proper compliance.
