| # | Interface | BMS scope (this proposal) | Other-discipline scope | Hand-off / interlock |
|---|-----------|---------------------------|------------------------|----------------------|
| 1 | **Mechanical (chiller plant)** | BMS supplies CHW supply/return T+P sensors, header instrumentation, condenser-water sensors. BMS reads chiller plant manager via BACnet/IP HLI. | ME contractor supplies chillers, primary/secondary CHW pumps, CW pumps, header piping, isolation valves, blowdown system. Chiller PLC + BACnet gateway by Equipment Supplier. | ME provides BACnet IP address + integration object list per equipment skid; BMS terminates HLI at DDC-2F-CHILLER. |
| 2 | **Mechanical (cooling towers)** | BMS supplies basin level sensors, ambient T/RH cluster, condenser-header T-sensors, blowdown valve, blowdown corrosion/scale sensor. BMS reads CT fan VFD via BACnet HLI. | ME contractor supplies cooling tower units, basin makeup water valve, fans + VFDs. | ME provides VFD BACnet card; BMS configures HLI parameters at DDC-RD-PLANT. |
| 3 | **Mechanical (AHU / PAHU / DOAS)** | BMS supplies T/RH/CO2 sensors at duct + room, supply-air pressure transmitter, modulating CHW valve actuator (BMS-supplied per MC Standards), VFD HLI integration. | ME contractor supplies AHU/PAHU/DOAS units, dampers, motors, integral CHW coils. Equipment Supplier provides VFDs with BACnet card. | BMS terminates VFD HLI at panel; BMS supplies sequences-of-operations for damper/valve modulation. |
| 4 | **Mechanical (boilers)** | BMS supplies flue-gas O2 sensor + flue-gas T-sensor + supply-steam pressure transmitter + feedwater T-sensor + blowdown valve. BMS reads burner controller via BACnet HLI. | ME contractor supplies steam boilers, burners, feedwater pumps. Burner controller + BACnet gateway by Equipment Supplier. | ME provides burner-controller BACnet integration spec; BMS terminates HLI at DDC-LG-PLANT. |
| 5 | **Plumbing (DHW)** | BMS supplies tank T-sensors, supply/return/makeup header T-sensors. | PL contractor supplies calorifiers, heat pumps, recirculating pumps, piping. Pump auxiliary contacts wired to BMS by PL contractor. | PL terminates aux-contact wires at DDC-LG-PLANT / DDC-RD-PLANT. |
| 6 | **Casino MVAC (Air Ionizers, VOC)** | BMS reads Air Ionizer status + VOC sensor via Modbus / BACnet MS-TP HLI. BMS supplies CO/CO2 sensors at return duct. | ME / Casino fit-out contractor supplies Air Ionizers (including their controllers) and provides Modbus integration spec. | Casino fit-out contractor delivers Modbus integration spec to BMS at shop-drawing stage. |
| 7 | **Electrical (BMS panel power)** | BMS supplies + installs BMS DDC field panels, internal wiring, terminations. | EE contractor provides 240V single-phase feeders (DBV-MECH/DBV-BMS) with dedicated breakers, terminating at the BMS panel input terminals. | EE terminates feeder breakers at the floor's DBV; BMS-installed feeder cable runs from DBV breaker to BMS panel input (per A7 power provisions). |
| 8 | **Electrical (energy metering)** | BMS supplies multifunction power meters at major load centers (chiller MCC, AHU MCC, lighting feeders), CTs, Modbus daisy-chain wiring, integration to head-end. | EE contractor supplies main switchgear + DBVs; provides metering stab compartments (or hot-tap) for CT installation. | EE provides as-built single-line + load-current data; BMS sites meters and finalizes Modbus addressing. |
| 9 | **Fire Detection & Alarm (FDAS)** | BMS reads FACP common alarm + common trouble + system status via BACnet/IP HLI gateway at FCC. BMS supplies the gateway's network-side wiring only. | EE/FDAS contractor supplies the FACP, all FDAS field devices, the BACnet gateway at FCC. | FDAS contractor provides BACnet object list + IP address; BMS terminates network wiring at DDC-GF-BOH. |
| 10 | **Architectural (control room + IDF closets)** | BMS occupies the Lower Ground IT/BOH room with the 12U BMS rack. | Architect provides the room (Q-011), AC, lighting, raised floor, room finish. ECE contractor provides the per-floor IDF closets with structured cabling. | Architect coordinates BMS rack location with the auxiliary-systems rack; ECE coordinates IDF tap-off for BMS Cat6 trunk. |
| 11 | **IT (network management)** | BMS LAN is isolated; head-end has a managed gateway / firewall to bridge to corporate IT (VPN access for FM team, time-sync NTP). | IT contractor / Megaworld FM team provides the corporate IT side of the gateway. | IT-BMS firewall rules and NTP settings agreed at commissioning; BMS provides the engineering hand-off. |
| 12 | **General building (containment)** | BMS installs branch conduit + per-device terminations + BMS-LAN Cat6 + MS/TP riser cable. | Main contractor / ME contractor supplies cable tray for primary backbone (per BMS-01 narrative, BMS rides ME-supplied tray). Civil contractor supplies slab penetrations. | Main-contractor coordination meeting at Phase D1 milestone; BMS provides cable-tray loading data. |
| 13 | **Casino regulatory (gaming-board IAQ)** | BMS provides CO + CO2 + VOC sensor data + alarm signaling for casino floor return air per Megaworld DRC-004 + gaming-board minimum requirements. | Megaworld Operations / Casino regulator confirms IAQ-monitoring acceptance criteria. | Megaworld provides regulator-approval evidence at SAT. (Q-012 if regulator wants extra metering.) |
