# C2 — Inter-discipline Coordination Matrix

**Project:** Kingsford Hotel Bacolod — BMS
**Date:** 2026-04-28
**Source:** BMS-01/02 spec + MC Standards C/O column + classification + assumption ledger

| Interface | Other party | What BMS provides | What other party provides | Coordination point | Risk if uncoordinated |
|-----------|-------------|--------------------|----------------------------|---------------------|------------------------|
| BMS ↔ Mechanical (HVAC) | ME Contractor | Field instrumentation (sensors, BMS-supplied valves, dampers), control wiring to ME-supplied actuators, controller logic | AHU/DOAS/PAHU/EAS units, ME-supplied valves & dampers, equipment installation, mechanical commissioning, equipment factory startup support | Equipment delivery dates, terminal-block schedule for ME-supplied actuators, valve actuator brand alignment | Schedule slip if ME equipment delivery delayed beyond installation window |
| BMS ↔ Electrical (EE) | EE Contractor | BMS panel internal wiring + Modbus pickup at meters | Power feeds to BMS panels (per A7 / A-007), conduit and cable tray for power circuits, multifunction power meters at main + sub-feeders, Modbus output card on power meters, fire-pump feeder per CB#8 single-feeder scheme | BMS panel circuit assignments (Q-009), power-meter Modbus communication settings | Re-pull of power feeder if circuit ID changes; meter Modbus parameter mismatch (baud / address) |
| BMS ↔ Plumbing (PL) | Plumbing Contractor | Calorifier, HW header, heat-pump, recirculating-pump field instrumentation; immersion temperature sensors | Calorifier tanks (with sensor wells), heat pumps, hot-water pumps, plumbing piping, sensor pocket fittings | Sensor-pocket inclusion in piping spool; calorifier delivery + sensor-tap availability | Field penetrations after pipe installation more expensive |
| BMS ↔ Casino tenant | Casino operator | Casino-AHU monitoring + Ozone generator status (BMS-02) | Casino fit-out coordination, access for installation, sign-off on Casino BMS scope | Q-003 — confirm Casino BMS is BMS Contractor scope or contracted separately | Scope re-cut if Casino owner declines integrated BMS |
| BMS ↔ Equipment Supplier (Chiller, AHU/DOAS, VFDs, fans, pumps) | Equipment Supplier | Auxiliary contact wiring termination at panel | Aux contacts (status / HOA / trip), VFD BACnet card, chiller native BACnet IP gateway, factory startup, parameter cheat-sheet | Equipment-side terminal block layout, BACnet object cheat-sheet for chillers + DOAS, VFD parameter map | Wrong addressing → P2P fail; commissioning delay |
| BMS ↔ Architectural | Architect / Main Contractor | Penetration drawings (cores, sleeves, wall passes), panel-room finish requirements | Cable tray routing approval, ceiling void access, riser-shaft slot allocation, panel-room finishing | Riser shaft allocation per EE-24 Part 1 (and Part 2 pending Q-008); ceiling-void containment per Q-005 | Tray collisions; unfinished panel rooms at handover |
| BMS ↔ FDAS | FDAS contractor | (Excluded scope — A-017 / Q-012) | n/a | n/a | If integration is later requested, change-order |
| BMS ↔ Security / Access / IT | Security/IT contractor | (Excluded — A-017) | n/a | n/a | Change-order if requested |
| BMS ↔ Civil / Cutting & Patching | General Contractor | Sleeve coordination drawings | Cutting & patching beyond 50 mm penetrations | Shop-drawing review + site instruction | Re-work if penetrations are mis-located |

## Notes

- "Coordination point" is the artifact or event that has to be jointly managed. Each row should map to at least one schedule task in D1 (e.g., `Equipment Supplier BACnet object cheat-sheet — Week 4`) or a clarification in `08-customer-clarifications.md`.
- Excluded scope (FDAS, Security, IT) is reflected in C3 inclusions/exclusions.
