Building 100 HVAC Repairs

The U.S. Coast Guard Sector San Francisco seeks proposals for HVAC repairs at Building 100, Yerba Buena Island. The project focuses on restoring two rooftop Air Handling Units (AHUs) to full operational status. For AHU #1, the scope includes R-410A refrigerant recovery, replacement of a seized 13.4-ton compressor, replacement of various electrical and system components (compressor contactors, circuit breakers, condenser fan contactors, auxiliary switches, crankcase heaters, liquid line filter drier), system leak checks, and a recharge with new R-410A refrigerant. AHU #1 also requires chemical cleaning of its condenser coil. For AHU #2, the contractor will perform diagnostics to identify the root cause of an “Interlock Error Code” and provide a detailed report with recommended repairs. All materials must be new, commercial-grade, and meet or exceed OEM specifications. The contractor must adhere to EPA and OSHA safety standards, manage waste, and coordinate access and work schedules with Coast Guard personnel. Security requirements include escorts in restricted areas, identification checks, and prior submission of personnel rosters, especially for foreign nationals. The project must be completed within 10 calendar days of the award date, with the physical work completed within three calendar days of the start date.
