- task: Conduit installation (BMS-scope branch conduit)
  quantity: 1293
  unit: m
  rate_h_per_unit: 0.1365
  hours: 176.5
  notes: "Conduit fraction = 25% of total cable. Basis: Greenfield hospitality with mixed routing \u2014 main backbone in ME-supplied tray\nalong service-core risers and BOH corridors; branch conduit from\
    \ tray drops to\nindividual field devices in plant rooms, on AHU casings, and at exhaust-fan\nmotor locations. Anchor at the lower end of the hospitality 0.25-0.35 range\nbecause BMS-01 narrative confirms\
    \ ME contractor supplies primary tray; BMS scope\nis therefore weighted toward branch + drop conduit (~25% of total cable in\nconduit, the rest in tray).\n"

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).
