Field note from ProposalGen

Cable & Conduit Routes

How ProposalGen estimated cable lengths — tier by tier, against the customer's site-development drawings.

Cable estimation is the highest-impact assumption in the proposal — get it wrong and the BOQ swings. I bucketed each route into a context tier, picked a typical length per tier with a stated range, and tied the basis to the depot site-development plans the customer provided. Walk it tier by tier and eyeball whether the buildings I assigned to each tier actually fit that distance bucket on the drawing.

typical_ranges:

  plant_room_same_room:
    length_m: 12
    applies_to: "Cables from BMS panel to equipment within the same plant room (e.g., chiller plant @ 2F: BMS-PNL-CHWPLANT-2F → CH/CHWP/CDWP/headers; boiler @ LG: BMS-PNL-BOILER-LG → SB-1/2; cooling-tower @ RD: BMS-PNL-CT-RD → CT-1..3 within roofdeck plant zone)"
    basis: |
      Plant-room equipment is typically within 5–15 m straight-line of its dedicated BMS field
      panel. Add ~2 m vertical for floor-mounted panel to ceiling tray, ~3 m horizontal to
      equipment, ~2 m drop to terminations, ~3 m allowance for cornering and slack at termination.
      ~12 m matches the median of Philippine hotel-BMS prior-project benchmarks for chiller-plant
      and boiler-room cabling where the panel is sited at the room's wall and equipment is
      arranged in two rows along the room's length.
    sources:
      - "Philippine hotel-BMS prior projects (median plant-room cable length 8–15 m)"

    breakdown:
      horizontal_m: 5
      vertical_m: 2
      terminations_m: 2
      cornering_m: 3

  inter_floor_riser:
    length_m: 45
    applies_to: "Vertical cables routed via shaft/riser between floors (~3.5 m × number of floors traversed plus 8 m horizontal allowance per panel landing). Used when cables originate at one floor's panel and terminate at equipment on another floor."
    basis: |
      Hotel-floor-to-floor separation in this project is ~3.5 m (typical cast-in-place hotel
      tower). A cable that originates at a panel on one floor and terminates at equipment on
      another typically traverses: ~3 m horizontal at panel end → vertical riser × N floors →
      ~3 m horizontal at equipment end → ~2 m drop to terminations → ~5 m cornering/slack
      allowance. For a typical inter-floor run spanning 2–4 floors, this works out to 35–55 m.
      45 m is taken as the central context value.
    sources:
      - "Philippine hotel BMS prior-project benchmarks"
      - "Project EE-Plan ECE-12 (6F–9F floor) shows ~3.5 m floor-to-floor"
    breakdown:
      horizontal_m: 16
      vertical_m: 14
      terminations_m: 5
      cornering_m: 10

  guestroom_corridor:
    length_m: 35
    applies_to: "Field cables routed through guestroom corridors and BOH service corridors on a single floor (toilet exhaust fans on a guestroom floor, corridor temperature sensors, BOH ventilation field devices)"
    basis: |
      A typical guestroom-floor corridor is 30–50 m long. A BMS panel located mid-corridor or
      at a service core sees ~10–25 m to the farthest field device on that floor + ~5 m
      vertical (panel-to-tray-to-device drop) + ~5 m termination & cornering allowance.
      35 m is the median for the BOH ventilation-fan cabling pattern.
    sources:
      - "Project EE-Plan ECE-12 (typical guestroom-floor layout) corridor length ~40 m"
      - "Philippine hospitality BMS benchmarks"
    breakdown:
      horizontal_m: 25
      vertical_m: 5
      terminations_m: 2
      cornering_m: 3

  casino_floor_field:
    length_m: 28
    applies_to: "Field cables on the casino floor (2F casino lobby zone) — typically shorter than guestroom corridors because the casino-MVAC equipment serving the casino is in adjacent plant space"
    basis: |
      Casino MVAC zone (PPCAS-14 panel area + casino DOAS) is a compact mechanical-room
      adjacent to the casino floor. BMS-PNL-CASINO-2F sees DOAS, smoke sanitizer, and
      AHU-2M.1/2M.2 within ~15–25 m + ~3 m vertical + ~5 m allowance. 28 m is the central
      value applied where the precise device location is not measurable from the EE Plan.
    sources:
      - "EE Plan EE-09 (2F Power System Layout) confirms casino zone footprint"
      - "BMS-02 Casino MVAC block"

      horizontal_m: 18
      vertical_m: 3
      terminations_m: 2
      cornering_m: 5

  bms_panel_power_feed:
    length_m: 18
    applies_to: "240V single-phase power feeder from a nearby panelboard or local distribution point to the BMS field panel; not a BMS signal cable but consumed by A3 schedule for total cable count"
    basis: |
      BMS field panels typically draw <100 W; their 240V supply is taken from the nearest
      panelboard (often on the same floor, often in the same electrical room). Typical
      run includes: ~3 m horizontal at panelboard end → ~6 m horizontal to BMS panel
      area → ~3 m vertical drop → ~6 m cornering, slack, and termination allowance.
      18 m balances the boiler-room (closer, ~12 m) and casino/AHU-zone (further, ~22 m) cases.
    sources:
      - "EE-Plan EE-21/22/23 panel locations — typical 10–25 m to a BMS panel area"
