At which meeting should the question about which finisher(s) can request water additions to the concrete be answered?

• A. Preconstruction meeting
• B. Safety briefing
• C. Daily crew meeting
• D. Quality control meeting

Answer: (A)

Decisions about modifying the concrete mix, like who can request water additions, are determined in the planning stage so responsibilities and approvals are clear before work begins. The preconstruction meeting is where the project team—engineers, designers, contractors, and QC—discusses and documents the approved process for field adjustments to the mix, including who has authority to authorize water additions and under what limits. This ensures everyone understands the procedure and that changes stay within the established mix design and project requirements.

Safety briefings focus on hazards and safe practices, not technical mix changes. Daily crew meetings handle day-to-day tasks and on-site coordination, but they don’t set the overarching authorization and documentation for mix adjustments. Quality control meetings deal with verifying conformance and testing results, but the authority and process for making mix adjustments should already be defined beforehand in the preconstruction planning.
