5. BAS / CONTROLS INTEGRATION – Existing System Identity and Integration Requirements

The SOW requires BACnet integration with the facility’s Building Automation System (BAS) and identifies specific monitoring points (pressure, pump status, run hours, VFD speed, kW, flow, and alarms). Respectfully requests clarification because the solicitation does not identify:

1. The existing BAS manufacturer and software platform (e.g., Siemens, Johnson Controls, Honeywell, Automated Logic, etc.)

1. BACnet communication protocol variant: BACnet/IP vs. BACnet MS/TP

1. Whether the Contractor is responsible for full BAS integration or only for providing BACnet-capable hardware and a BAS operator will perform the integration

1. Nearest BAS field controller location and available network port/capacity for connection

1. Whether integration must be completed and commissioned by the BAS OEM or authorized integrator

Because this information materially affects price, schedule, and technical approach, please confirm the BAS details and integration responsibilities, or issue a formal amendment. If this information will not be available before the proposal due date, please confirm whether offerors may submit pricing based on stated assumptions.

7. PRICE BREAKDOWN FORM – Apparent Scope Inconsistencies respectfully notes that the attached Price Breakdown form (Attachment Price Breakdown – Improve Water Pressure.xlsx) contains line items that appear inconsistent with the booster pump installation scope described in the SOW. Specifically, the Price Breakdown references the following items for which no corresponding SOW requirement exists:

1. Division 22 – Plumbing: Lavatory (P-507), Lavatory wall-mounted (P-418), drain piping (2” coated cast iron), vent piping (2” coated cast iron), mixing valves, fixtures, solid interceptor

1. Division 08 – Doors and Windows: New exam room door, door hardware, door frame

1. Division 27 – Communications: Nurse call system

1. Division 23 – HVAC: HVAC ductwork and registers

These line items suggest the Price Breakdown template may have been carried over from a different project and was not fully updated for this scope.

VA Response: These divisions can be removed or edited as needed.
