A modern construction site might have 15-20 subcontractors working across day and night shifts. The electrical sub needs a wall open that the drywall sub is closing. The plumber is waiting for an inspection that the GC forgot to schedule. Coordination failures cost the US construction industry an estimated $177 billion annually.
The coordination breakdown
Day shift: The mechanical sub installs ductwork in Zone B. They finish 80% and plan to complete it on the next day shift. They tell the superintendent verbally. Night shift: The framing sub arrives to close up walls in Zone B. They weren't told about the incomplete ductwork. They close the walls. Next day: The mechanical sub has to tear out drywall to finish their work. Two days and $15,000 wasted.
What subcontractor coordination handoffs need
- Work-in-progress by zone: What's incomplete and where. Don't let anyone close up work that isn't done.
- Area access restrictions: Which zones are off-limits, who's working where, and when they'll be done.
- Inspection status: What passed, what failed, what's scheduled. Failing to get an inspection before covering work is expensive.
- Material staging: Where materials are staged for which sub. Prevent one crew from moving another's materials.
- Schedule changes: Any sub that's ahead or behind schedule. Communicate it so other trades can adjust.
One source of truth
ShiftVoice gives every shift a single source of truth for site coordination. The day superintendent records a handoff covering all active work zones, the night foreman sees it organized by category and urgency, and nobody closes walls over unfinished ductwork.
