  project: Kingsford Hotel Bacolod — BMS (AB-Run-6)

# Greenfield hospitality build — BMS rides ME-supplied cable tray for plant
# rooms and main BOH risers; BMS installs branch conduit from tray drops to
# field devices. Hospitality finish-out has more branch routing than a pure
# warehouse / industrial greenfield.
conduit_fraction_of_total_cable: 0.25
conduit_fraction_basis: |
  Greenfield hospitality with mixed routing — main backbone in ME-supplied tray
  along service-core risers and BOH corridors; branch conduit from tray drops to
  individual field devices in plant rooms, on AHU casings, and at exhaust-fan
  motor locations. Anchor at the lower end of the hospitality 0.25-0.35 range
  because BMS-01 narrative confirms ME contractor supplies primary tray; BMS scope
  is therefore weighted toward branch + drop conduit (~25% of total cable in
  conduit, the rest in tray).

# Greenfield day-work baseline. No retrofit / occupied-building / night-work
# modifiers apply. Light reserve for high-ceiling plant-room rigging at chiller
# room (~5 m clear height) and roof deck cooling-tower platforms.
production_rate_modifier: 1.05
production_rate_modifier_basis: |
  Greenfield day-work base = 1.0; +5% for high-ceiling chiller-room and rooftop
  cooling-tower rigging (mobile elevated work platform / scaffold required for
  CT fan motor and DOAS rooftop AHU access). No after-hours premium (greenfield
  pre-occupancy). No retrofit modifier (Greenfield per A-001).

# Specialty / commissioning factors per project context
sensor_calibration_per_ai: 0.75
sensor_calibration_per_ai_basis: |
  Standard hospitality calibration baseline. Bump per-AI rate for high-precision
  IAQ (CO/CO2/VOC) sensors at the casino floor — bundled into the device install
  rate already, not the per-point rate.

penetration_fraction_of_cable_ends: 0.35
penetration_fraction_of_cable_ends_basis: |
  Multi-floor building with vertical riser shaft + per-floor BOH-corridor tray
  + per-floor branch routing into mechanical rooms / AHU rooms. Typical 30-40%
  of cable ends require slab/wall penetration (riser shaft, MEP-room doors,
  service-core IDF cabinets). Refined to 0.35 reflecting the relatively
  contained service-core stack (single west-end vertical path) versus a more
  spread-out multi-shaft building.

penetration_rate_h: 0.5

site_safety_pct: 0.06
site_safety_pct_basis: |
  Hospitality greenfield baseline 5%, +1% for working alongside the casino
  fit-out (gaming-floor finish-out is happening in parallel with BMS commissioning;
  enhanced PPE/permits expected for casino-zone access).

punch_list_pct: 0.05
punch_list_pct_basis: |
  Standard 5%. Engineering inputs are reasonably mature (Construction Bulletin
  No.8 stable; consultant points list explicit). No bump warranted.

documentation_pct: 0.05
documentation_pct_basis: |
  Megaworld submittal workflow is more rigorous than a non-DRC project (Megaworld
  Engineering Design Department reviewed Construction Bulletins on 05Dec25 — same
  workflow expected for BMS submittals + shop drawings + as-builts). Bump from
  baseline 4% to 5%.
