**WBS leaves served:** 2.7.1, 2.7.2, 2.7.3, 2.7.4, 2.7.5, 2.7.6, 3.2, 3.3
**Module ref:** `_playbook/modules/bms/cabling-and-containment.md`
**Project:** Kingsford Hotel Bacolod BMS

## Project-specific parameter values

(All from A3 cable schedule)

- `total_signal_cable_m`: ~5,250 (4C × 1.5 mm² shielded FRLS — main category)
- `total_network_cable_m`: ~1,200 (Cat6 + fiber + Modbus trunks)
- `total_power_cable_m`: ~540 (3C × 2.5 mm² panel power feeds, 18 × 30 m)
- `total_conduit_m`: ~2,043 (~30% of 6,810 m)
- `total_tray_m`: TBD per Q-008 (assume 0 in BMS scope; ME provides in plant rooms)
- Field cables: 175
- Trunks: 7
- Panel power feeds: 18

## BOQ line items (Phase 6 input)

| WBS | Description | Qty | Unit | Reference |
|-----|-------------|-----|------|-----------|
| 2.7.1 | 4C × 1.5 mm² shielded FRLS control/signal cable | ~5,250 | m | A3 BMS-side, ME-side, EQ-supplier-side cables (most common) |
| 2.7.1 | 6C/8C × 1.5 mm² shielded FRLS (where conductor count > 4) | ~500 | m | A3 (a few wider runs) |
| 2.7.2 | BACnet MS/TP shielded TP low-cap | ~150 | m | A3 BACnet MS/TP trunk |
| 2.7.3 | Cat6 4P × 23 AWG U/UTP FRLS jacket — patch + permanent links | ~700 | m | A3 network drops |
| 2.7.3 | Cat6 patch cables (1–3 m factory-made) | 80 | each | A5 |
| 2.7.4 | OM3 multimode 6-strand armored fiber riser | 300 | m | A5 |
| 2.7.4 | Fiber transceivers (1G SX/LX, paired) | 14 | each | A5 (also in network module) |
| 2.7.5 | Conduit (PVC HW or EMT, 20–25 mm) | ~2,043 | m | 30% of total cable |
| 2.7.5 | Junction boxes / pull boxes | ~100 | each | 1 per 20 m of conduit |
| 2.7.5 | Cable trays (BMS-only spaces — server room, edge IDFs) | TBD | m | per Q-008 |
| 2.7.6 | Cable identification (labels, ferrules, marker tags) | 1 | lot | per cable count + 50% spare |
| 2.7 | Modbus shielded TP cable (counted in field-devices-power module — see 2.6) | (already counted) | — | A3 Modbus trunk |
| 2.7 | 3C × 2.5 mm² FRLS panel power feed cable | 540 | m | 18 panels × 30 m |
| 3.2 | First-fix containment installation (conduit, supports, mounting plates) | 266 | hr | B4: 2,043 m × 0.13 hr/m |
| 3.3 | Cable pulling — control + network + power feeds | 2,247 | hr | B4: 6,810 m × 0.33 hr/m |
| | **Total cabling labor** | **2,513** | hr | (largest single labor pool — per B4) |

(Note: termination + testing labor is shared across all field-devices modules — counted in B4 separately, not double-counted here.)

## Open assumptions for this instance

- A-001: 30 m avg run per cable, 80 m trunk per floor — refine after Q-005/Q-008
- A-001-supplemental: BMS provides own conduit for branches (~30% of total cable length); ME-supplied trays in plant rooms (per Q-008)
- FRLS jacket required (fire safety / building code)
- Pull box density: 1 per 20 m of conduit run
- Cable tray BOQ uncertain until Q-008 — flag in inclusions/exclusions

## Cross-references

- **Working docs:** A3 (cable schedule — primary), A1 (point count drives cable count), A5 (network cabling), A7 (panel power feeds)
- **Assumptions:** A-001, A-001-supplemental
- **Clarifications:** Q-005 (architectural), Q-008 (mech layouts — refines tray vs. conduit split)
