Leveling Impact Assessment
The resource leveling run (v4.1, 27 Feb 2026) reveals a 106-calendar-day project end date slip driven almost entirely by the electrician shortage (25 persons below peak demand). The delay propagates through the electrical rough-in chain (E-2410 → E-2430 → Pre-Commissioning → Mechanical Completion) which sits on the critical path.
- Acceptable impact: 13 activities delayed 1–20 days against float > 20d — no action needed. These are primarily civil and concrete activities in non-critical zones.
- Recovery priority: Resolving the 25-person electrician shortfall (R-21 action) eliminates the E-2410 delay chain and recovers approximately 62 days — reducing net end date slip from 106d to 44d.
- Remaining 44d gap: Primarily driven by mechanical fitter shortage (5 persons). Overtime authorization for M-3100 series (10% premium cost, est. $42K) can recover 20–25 days. The remaining 20–24 days can be addressed through scope/logic optimization (R-27 recovery schedule).
- Leveling run must be re-executed after resource augmentation is confirmed — target: v4.2 by 14 Mar 2026.
