Drywall Start, Open Junction Boxes, and One Scissor Lift
On a commercial renovation, the drywall crew is scheduled to begin hanging on the second floor Monday. On Friday afternoon, the electrical foreman reports that most of the rough-in is complete but three junction boxes above the corridor ceiling are still not installed because an RFI about the ceiling height is unanswered. The drywall superintendent says his 12-person crew will be idle Monday if they cannot start, and the project is already five days behind. The general contractor wants drywall started in the unaffected rooms. The electrical crew needs a scissor lift that is currently assigned to the drywall crew for Monday. The RFI was submitted nine days ago; the typical response is five business days. The ceiling-height conflict affects 60 feet of corridor and one rated wall.
1. What sequencing decision should the crew lead recommend for Monday, and what facts must be confirmed before the drywall crew mobilizes?
Read the worked answer
Recommend a split release, not a blanket start. The lead should confirm which second-floor rooms are genuinely unaffected by the RFI and whether the electrical rough-in in those areas has passed inspection. Drywall should start only where the ceiling and rated wall will not be opened later; hanging board over unresolved junction boxes in the corridor creates rework and possibly a fire-rated assembly problem.
Facts to confirm before mobilization: the electrical inspection status by room, the exact corridor and rated-wall scope affected by the ceiling-height RFI, and the scissor-lift schedule. The drywall crew can work in unaffected rooms Monday while the electrical crew uses the lift in the corridor first. The corridor drywall should be held until the RFI is answered.
Why not simply start everywhere? The project is five days behind, but rework in a rated corridor costs more than a one-day sequencing change. The lead's job is to protect the critical path, not to keep every crew busy at any cost.
2. How should the lead communicate the plan to the drywall and electrical foremen and to the GC so that no crew is surprised on Monday?
Read the worked answer
Hold a short coordination meeting Friday before the end of shift with the drywall foreman, electrical foreman, and GC superintendent. Bring a one-page plan: rooms released Monday, rooms held, lift assignment by time block, RFI status, and the person responsible for each action. Read back the plan and ask each foreman to confirm.
Follow up in writing the same day-email or text with the plan and the decisions-so Monday's startup does not depend on memory. The lead should state the risk plainly: if the corridor is boarded before the RFI answer, the crew may have to remove and replace rated drywall.
Why not just tell the drywall crew to wait? That leaves 12 people idle and invites the GC to push anyway. A specific partial release gives the drywall foreman productive work, gives the electrical crew lift access, and keeps the unresolved area visibly open. The lead should also set a checkpoint: if the RFI is not answered by Monday noon, escalate to the GC's project manager.
3. The RFI response arrives Monday at 3 p.m. and changes the ceiling height. What should the lead do about the work already started and the schedule?
Read the worked answer
Protect the unfinished area first. If the RFI changes the ceiling height, the lead should stop drywall work in the affected corridor and confirm whether any board already hung must come down. The electrical rough-in must be corrected before the ceiling is closed, and the rated wall detail must be reviewed. The lead should not let the drywall crew 'close it up and fix it later.'
Re-sequence: move drywall labor to unaffected rooms, ask the GC for a formal response time, and update the two-week lookahead. The electrical crew should get priority on the corridor and lift. If the change adds cost or time, the lead should notify the project manager so a change order or delay notice can be prepared.
Document: the RFI date, the response date, the work stopped, and the labor and material impact. The lead should communicate the revised plan to both foremen in writing and confirm that the GC accepts the hold. The goal is to absorb the change without creating concealed noncompliant work.
