DESCRIPTION OF SERVICES:

The contractor shall provide all personnel, equipment, tools, materials, supervision, and quality control necessary to replace the HVAC system in Building 4983 at JBSA Lackland. The 502d Civil Engineer Squadron requires the decommissioning and removal of the existing 15-ton direct expansion (DX) split system. The legacy system operates on phased-out R-22 refrigerant and consists of a Rheem Air-Cooled Condensing Unit (Model No. RAWE-180CAZ, Serial No. 6698F010904536) and a corresponding RUUD Air Handling Unit (Model No. RHCE-150ZK, Serial No. 114G029900259). This project includes the complete installation of a new, fully functional, code-compliant 15-ton HVAC system equipped with modern Direct Digital Controls (DDC) and BACnet-compatible building automation capabilities.

5. Additional Questions to Consider in Response to this RFI:

Technical Approach & Systems Integration

a) Load Calculation & Sizing: The DRAFT SOW requires the new system to be "sized to meet building load requirements." Please describe your methodology for performing the building load calculation to confirm if the existing 15-ton capacity is accurate or if a different size is optimal for energy efficiency and performance.

Response:

b) Equipment Footprint & Installation: Based on the requirement to install a new, modern system, do you anticipate that the new Air-Cooled Condensing Unit (ACCU) will fit on the existing concrete equipment pad? If modifications are needed, please describe them.

c) Ductwork Integration: The DRAFT SOW requires the removal of "ductwork if determined incompatible." Based on your experience with similar retrofits, what specific conditions would lead you to determine the existing ductwork is incompatible with a new Air Handling Unit (AHU)?

Section 2: Controls & Automation

a) BACnet Integration & Open Systems: The DRAFT SOW requires a BACnet-compatible DDC interface. Please confirm your proposed solution uses a BTL-Certified, native BACnet controller that allows for full integration into a base-wide EMCS without requiring proprietary gateways or brand-specific software licenses for monitoring and control.

b) Commissioning & Verification: The DRAFT SOW requires a commissioning report and performance verification. What key performance indicators (KPIs) and testing methods would you use during commissioning to verify that the new 15-ton system is operating at peak efficiency as a "complete, operational, commissioned HVAC system"?

Section 3: Compliance

a) Refrigerant Line Set: The DRAFT SOW mandates "New refrigerant piping." Please confirm you understand this requirement and that no portion of the legacy line set will be flushed or reused.
