When should the final site check be for debris/cleanliness/lack of water?

• A. The morning of erection
• B. The afternoon of erection
• C. Before site mobilization
• D. After erection

Answer: (A)

Final readiness for tilt-up erection means confirming the work area is clean, dry, and free of debris and standing water right before you start lifting panels. Doing this in the morning aligns with the start of erection activities, so any issues can be spotted and addressed before the first lift. Debris and moisture on the slab can cause slips, interfere with crane movement and panel handling, and risk damage to forms or fresh concrete. If you wait until after erection has begun, hazards would already be present during lifting. Checking before site mobilization is premature for the actual erection work, since the goal is to verify readiness immediately prior to lifting.
