What is the inspector's role in verifying joint layout lines and timing for saw-cutting?

• A. Confirm joint locations with plan, verify saw-cut timing to not compromise set, and ensure joints are clean and sealed.
• B. Determine pour order.
• C. Estimate curing duration.
• D. Set repaint schedule.

Answer: (A)

The main idea is that cracking control hinges on getting joints where the plans show and cutting them at the right moment, then finishing the joints properly. The inspector must confirm joint locations match the design plan so the expected crack control is achieved. He or she also checks the timing of saw-cutting to ensure it occurs when the concrete has enough strength to form a clean, effective joint without compromising the set or causing damage. After cutting, the joints should be clean and sealed to prevent debris, moisture intrusion, and premature deterioration, preserving the joint’s performance.

Other activities like deciding pour order, estimating curing duration, or setting a repaint schedule don’t address these joint layout and timing aspects, so they aren’t the focus of this role.
