## Peak loading

- **Peak week:** Week 19–20 (cabling × panels × devices × programming overlapping) — 8.5 person-week total → typical site footprint ~7-person crew + 1-2 offsite engineers.
- **Tail loading:** Week 30+ tapers to PE + commissioning engineer for handover.

## Conversion sanity check

- Total person-weeks in table: 136 ≈ 5,440 person-hours
- Total task hours from B1+B2+B3+B4: 1,435 + 174 + 256 + 178 = 2,043 hours
- Difference (~3,400 hours) ≈ PM/PE/SP/coordination overhead + travel + downtime — this matches the ~2.6× labour-loading factor typical for BMS contractors on site-installed projects.

## Mobilization implications

- Engineering crew (PE+DE) mobilized week 1; office-based.
- Site crew (SP+EL+TE) mobilized week 13 with containment.
- Commissioning crew (CE) mobilized week 23.
- Trainer mobilized week 29 only.
