About this file
This is a Statement of Work (SOW) issued by the National Oceanic and Atmospheric Administration (NOAA), National Marine Fisheries Service (NMFS), Northwest Fisheries Science Center (NWFSC) for the replacement of an 80-ton chiller at the Manchester Research Station in Port Orchard, Washington. The contractor must remove the existing Century 80-ton chiller (installed 2005, using R22 refrigerant) and install a new air-cooled 80-ton chiller that maintains equivalent performance using existing infrastructure including a 3,000-gallon glycol tank, pumps, piping, concrete pad, electrical service, and seawater heat exchangers. The project location is at 7305 Beach Drive, Port Orchard, WA 98366, and the estimated completion date is 270 days after Notice to Proceed (NTP).
The new chiller must meet specific performance requirements: 80-ton minimum capacity, full cooling capacity at 95°F ambient dry-bulb temperature, 25% propylene glycol solution, 28°F leaving and 32°F entering glycol temperature, and comply with UL 1995, NEC, AHRI 550/590 & 551/591, and ANSI/ASHRAE 15 standards. The system must be rated for 3-phase 480VAC 60Hz operation in a marine/coastal environment with ambient temperatures ranging from minus 18°C to 46°C. The chiller must use hermetically sealed scroll-type compressors with crankcase heaters, corrosion-resistant copper tubes with aluminum fins and epoxy coating, galvanized steel frame with powder-coat finish, and low-GWP, EPA-approved refrigerant (R32 or equivalent). Controls must include BACnet-compatible interface, digital display, alarm diagnostics, leaving fluid temperature control, freeze protection, low ambient temperature controls, and automatic lead/lag compressor staging. The contractor must provide a detailed work plan for NWFSC approval 30 calendar days after NTP, submit a safety plan, project schedule, and product substitution requests before procurement. Deliverables include removal of the existing chiller with proper EPA-compliant refrigerant disposal, installation and testing by a manufacturer-certified technician, a commissioning report, training for NWFSC personnel within five working days post-commissioning, one-year labor and craftsmanship warranty, as-built drawings (2 hard copies, 1 PDF, 1 CAD file), and an Operations & Maintenance manual (2 hard copies, 1 PDF). Standard work hours are 8:00 a.m. to 4:30 p.m., Monday through Friday, with 24-hour notice required for outside-hours work. The Contracting Officer Representative is Thanh Minh Trinh, P.E. (thanh.m.trinh@noaa.gov, 206-860-6798), and the Task Monitor at Manchester Research Station is Shawn Katz (shawn.katz@noaa.gov, 360-871-8306).
