Phase 0: Preconstruction alignment
- Confirm decision-maker, approval path, and communication cadence.
- Define occupied hours, noise restrictions, and non-negotiable access routes.
- Document permit milestones and required inspections before start.
- Create zone map with temporary circulation and swing-space plan.
Phase 1: Containment and life-safety setup
Before demolition, establish work-zone protection for occupants and building systems.
- Install barriers, negative air where needed, and clean entry/exit paths.
- Protect fire/life-safety devices during dusty operations.
- Post wayfinding and notify occupants of route changes.
- Validate daily open/close checklist for each active zone.
Phase 2: Trade sequencing by zone
| Zone phase | Typical sequence | Control point before next phase |
|---|---|---|
| Zone A | Selective demo, rough-in, inspections, close-up, finishes. | Punch list below threshold and area clean for occupancy. |
| Zone B | Starts only after Zone A handoff acceptance. | Access routes and occupant flow revalidated. |
| Zone C+ | Repeat with learned adjustments from prior zones. | No carryover defects that block active operations. |
Phase 3: Daily closeout discipline
Occupied projects succeed when every shift ends in a safe, clean state.
- Debris removed and egress paths fully clear before occupancy resumes.
- Temporary protections checked and reset each day.
- Progress notes and photos issued with next-day work plan.
- Open issues logged with owner and due dates.
Phase 4: Final turnover and stabilization
- Zone-by-zone functional checks and punch completion.
- Client walkthrough with accepted completion standard.
- Closeout package: key notes, as-built updates, and follow-up items.
- 30-day stabilization check for adjustments after re-occupancy.
For occupied renovation, schedule reliability is driven by phasing quality, not speed alone. Clean handoffs between zones are what protect both the business and the budget.
