Living document. RFIs raised here for the customer to confirm or close. Each item references the assumption it would replace.

---

| ID | Question | Why it matters | Current assumption | Impact if answered | Source |
|----|----------|----------------|---------------------|---------------------|--------|
| Q-001 | The cover letter uses the wording *"Rehabilitation"* but the EE and BMS Construction Bulletins are issued for new construction with no existing-system inventory. Please confirm whether this is greenfield (we proceed accordingly) or whether an existing BMS is being replaced (we will need an existing-system inventory + cutover plan). | Stage classification drives demolition scope, after-hours premium, cable-reuse evaluation. Wrong answer ≈ PHP 2-4M cost impact. | Greenfield (A-001) | Confirms or pivots scope. | Cover letter (`Requirement.rtf`) vs EE Plan / BMS Points List Construction Bulletins |
| Q-002 | Required warranty period and conditions? | Drives commercial loading. | 1 year hardware + workmanship warranty (A-002) | Adjusts price by ~1-3% per year extension. | (not stated in inputs) |
| Q-003 | Post-handover maintenance contract — separate scope or included in this proposal? | Affects commercial loading + helpdesk scope. | Excluded from this proposal; offered as optional addendum (A-002) | Adjusts price + recurring revenue line. | (not stated) |
| Q-004 | Megaworld DRC-004-2024 Section 9 — please share the brand-approval list. Internal preferred is Siemens (BMS / FDAS) and Dell (PCs/server). | Brand substitutions during shop-drawing review can shift cost ±5-15%. | Siemens / Dell (A-003) | Confirms or replaces brand selections. | `_customer-kb/megaworld/approved-brands.md` Q-MW-001 |
| Q-005 | Architectural floor plans — please share. | Required for accurate cable-route measurement (corridor lengths, tray paths, riser locations). Without it, ~40-60% of cable lengths fall back to project-specific typical-range estimates. | Cable lengths fall back to typical ranges per `A3-route-lengths.yaml` (A-004) | Replaces fallback with measured values where applicable. | doc inventory |
| Q-006 | Mechanical (HVAC) layouts — equipment locations, ductwork routing, FCU/VAV placement. Please share. | HVAC equipment locations confirm guestroom-zone counts, FCU/VAV per-floor density, AHU/PAHU plant locations. | Equipment counts inferred from points-list zoning + typical hotel density (A-005) | Refines guestroom-floor counts and FCU cable counts. | doc inventory |
| Q-007 | If existing BMS is being replaced (per Q-001 outcome): please share existing controller inventory, panel locations, and cabling reuse intent. | Drives demolition + reuse decisions. | N/A unless Q-001 answers "rehab" (A-006) | Critical for rehab scope. | doc inventory |
| Q-008 | Has an "EL" (Electrical) BMS points-list partition been issued or is one forthcoming? Per Megaworld DRC-004, energy submetering is required at all major load centers — we expect a points-list addendum covering main-board / chiller MCC / AHU MCC / lighting feeder meters. | Defines whether power-quality / energy-monitoring scope is in this proposal or a separate package. | Limited to power meters at major load centers per Megaworld DRC-004; no main-board incomers, no UPS/genset monitoring (A-007) | Adds or removes a 30-50 point energy-monitoring scope. | DRC-004 / `_customer-kb/megaworld/approved-brands.md` |
| Q-009 | Plumbing BMS scope — Part C of the points list covers domestic hot-water only. Should sump pumps, fire pumps, transfer pumps, and sewage equipment also be on BMS? | Defines BMS scope vs. ME-package monitoring. | BMS scope limited to domestic hot-water per Part C (A-008) | Adds or removes a 20-40 point plumbing scope. | MC Standards - PL Points list.pdf |
| Q-010 | Building stack — please confirm: Basement / LG / GF / 2F amenity / 3F amenity / 4F transition / 5F mixed F&B+guestroom / 6F-11F typical guestroom (~24 keys) / 12F club floor / Roof Deck plant. | Drives equipment-instance count for guestroom-zone aggregation and inter-floor cable runs. | Stack inferred from EE plan + points-list zoning (A-009) | Refines per-floor equipment count. | inferred |
| Q-011 | BMS Server + control room location — typically in Lower Ground or Ground Floor BOH. Please confirm. | Drives head-end siting + uplink trunk lengths. | Lower Ground IT/BOH room assumed | Refines A5 architecture and trunk lengths. | inferred |
| Q-012 | Casino / gaming-floor adjacency — Kingsford casino floors share the building. Are there gaming-board IAQ requirements (CO sensors at return air per local gaming-board minimums) that fall in BMS scope? | Adds CO-sensor scope at gaming-floor return air. | Not in scope unless customer confirms | Adds 20-40 sensor + cabling rows. | `_customer-kb/megaworld/approved-brands.md` |
| Q-013 | Number of typical guestroom FCUs per floor and per FCU-class — verify against M-plan. | Drives guestroom field-device count. | ~24 FCUs per typical guestroom floor (× 6 typical floors = 144 FCU instances), 1 thermostat each per A-009 | Refines guestroom field-device count. | inferred |
| Q-014 | Power Riser Diagram (sheet EE-24 per cover letter) and Load Schedules (EE-21/22/23) — these were listed in the EE Plan transmittal but the binder pages 17-22 contain ECE-10..ECE-15 auxiliary-system layouts (FDAS, low-voltage). Can you re-issue the riser + load schedules? | A5 (network architecture) + A7 (power provisions) need the riser + schedule for proper sizing. | Single-shaft riser + standard 1.5mm² copper feeder per panel assumed (A-010) | Confirms or refines BMS panel power-feed circuit IDs. | EE Plan binder vs cover letter |
| Q-015 | DDC field-controller protocol confirmation — BMS-03 P&ID sheet shows NETWORK row at every equipment skid implying BACnet MS/TP at field, BACnet/IP at supervisory. Confirm. | Drives field-bus topology + cable spec. | BACnet MS/TP at field + BACnet/IP at head-end (per DRC-004) | Confirms or refines protocol. | BMS-03 + Megaworld customer-kb |
