SUMMARY: Department of Veterans Affairs, Veterans Health Administration, Network Contracting Office 5, is issuing this request for sources sought notice in order to identify vendors that are interested in and capable of providing contractor services. For a contractor to provide HVAC repair services for the Polytrauma Suite. Located at the Washington DC VAMC. Scope of Work: Project Number: 688-25-4-478-0163 Location: Washington DC VAMC, 50 Irving Street NW, Washington, DC 20422 Objective: This project will retrofit and modify the HVAC system serving the Polytrauma Suite to address system deficiencies and improve thermal performance, while maintaining compliance with VA design guides, federal standards, and relevant codes. 1. Dual-Duct Terminal Installation Furnish and install a 1200 CFM dual-duct terminal box above ceiling as shown on design documents. The new terminal box shall control digitally and capable of modulating the air via of control damper. Connect to existing hot and cold deck supply ductwork in the hallway plenum. Installation shall comply with SMACNA duct construction standards. 2. Ductwork Demolition and Reconfiguration Demolish and remove all branch ductwork and diffusers from the existing hallway VAV terminals. Seal duct openings upstream of the VAVs to isolate service to individual rooms. All work shall adhere to IMC requirements. 3. Duct Extension and Diffuser Installation Extend duct from new dual-duct terminal into hallway ceiling space. Install six (6) 24"x24" lay-in diffusers and four (4) matching intake grilles for plenum air transfer. Placement to conform with ASHRAE 55 thermal comfort criteria and match architectural aesthetics. 4. Inline Exhaust System Upgrade Provide and install a ceiling-mounted inline exhaust fan. Connect to existing relief system; design for 1200 CFM capacity, adjustable to 800 CFM. Include vibration isolators and flexible duct connectors. Fan shall operate at 45 db. Installation must meet IMC and NFPA 90A. 5. Make-Up Air Damper Deactivation The outside air intake to the unit shall be capped off 6 feet up stream from the unit; modify the ductwork to the unit as intake air from the planum to the unit per IMC. Furnish and install a 16"x20" return grille upstream of filters above hallway ceiling, ensuring unrestricted airflow. Maintain code-compliant ventilation through the new terminal box. 6. VAV Modification Room GC-228 Adjust VAV terminal to supply a constant 150 CFM (originally 800 CFM). Final airflow must meet ASHRAE 62.1 minimum ventilation guidelines. 7. Chilled Water Cassette Installation Room GC-228 Furnish and install a 1-ton chilled water cassette unit with variable-speed fan. Route insulated condensate drain to the nearest IPC-compliant sanitary drain. Include overflow protection and shutoff sensors. 8. Chilled Water Piping Run new 1 Type L copper piping from the unit to main chilled water riser (no tie-ins to AHU piping). Run new 1 type L coper piping from the unit to main hot water supply that suppling to the existing VAV reheat system. Confirm riser access and routing in crawlspace with COR. All piping to comply with ASME B31.9 and be hydrostatically tested. 9. VAV Box Replacement GC-212 to GC-216 Replace existing VAVs in Rooms GC-212 through GC-216 with new Siemens-compatible units. Each shall modulate between 50 120 CFM and feature digital thermostats. Controls shall meet BACnet protocol and be installed to SMACNA standards. 10. Insulation Requirements All ductwork to be insulated with 1.5" fiberglass insulation, conforming to ASTM C411. Pipe insulation shall meet ASHRAE 90.1 and local energy codes. 11. Work Schedule & Logistics All work to be executed during weekends or scheduled downtimes. Contractors must coordinate access, staging, and delivery with facility personnel. Pre-work verification of site conditions and material readiness is mandatory. 12. Testing, Adjusting, and Balancing (TAB) Employ a certified NEBB or AABC TAB contractor for final system balancing. Submit TAB report with airflow measurements, setpoints, and system calibration data to COR. 13. Controls Integration All HVAC controls work shall be executed by authorized Siemens technicians. Siemens to assess and report on control system integrity. Connect the control to the BAS. Programming must align with VA cybersecurity protocols and system specs. 14. Accessary and option for ne cassette unit. Unit will be 4-pipe system Freeze protection sensor for HWC Disconnect switch, 115 volts Unit shall be Lowe blower speed with sound absorbance cabinet insulation Back ward centrifugal fan Internal fire-resistant foam insulation Lightweight internal galvanized sheet steel wit integral fan mounted rails. If the ceiling cavity not deep enough, provide a finish look to the cassette. Mechanical digital thermostat and control shall connect to the BAS. 15. Commissioning and Documentation for Acceptance: Upon project completion, the contractor shall provide all necessary warranties and operational manuals for the new equipment. 15.1 Commissioning - Perform commissioning of all repaired or replaced HVAC system components in accordance with VA standards and industry best practices. - Commissioning activities shall include, but are not limited to: - Verification of installation and operation of all HVAC components. - Functional performance testing of system controls, safety devices, and alarms. - Airflow and temperature balancing. - Testing and adjustment of system setpoints for optimal performance. - Training of VA staff on new or modified system components and controls. - The Contractor shall coordinate all commissioning activities with the VA Medical Center s designated Commissioning Authority (CxA) and provide access for inspections and testing. 15.2 Documentation for Acceptance - The Contractor shall submit the following documentation for final acceptance: - **Commissioning Report: Detailing all tests performed, results, and corrective actions taken. - **Certification Documents: Including third-party verification if required. - **Operation and Maintenance Manuals: For all new or modified equipment. - **As-Built Documentation: Updated CAD drawings/diagrams reflecting all changes to the building s HVAC system.
