    2 person crew: 49.9
    3 person crew: 33.3
    4 person crew: 25.0
    6 person crew: 16.6
notes:
- Hours are per-task base hours. Trade split applies to total post-overhead hours.
- Schedule estimate assumes 5-day work week, 8-hr days, no concurrent activity overlap.
- Add ~10-20% if night-work for guestroom floors required (unlikely for greenfield per A-010-rev).
- Excludes engineering hours (B1+B2 covers programming hours separately).
- Excludes T&C hours (B3 covers commissioning hours separately).
