Manchester 80-Ton Chiller Replacement

1.0 ORGANIZATION. The Northwest Fisheries Science Center (NWFSC) is a marine research organization owned and operated by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Marine Fisheries Service (NMFS). NWFSC has five

(5) major campuses located in Washington and Oregon with its regional headquarters located in Seattle, WA.

2.0 PROJECT LOCATION. The project described in this Statement of Work (SOW) is located at the Manchester Research Station located at 7305 Beach Drive, Port Orchard, WA 98366. See Figure 1 of Exhibit A.

3.0 REQUIRED SERVICES. The contractor shall provide all labor, materials, tools, equipment, supervision, and incidentals to remove the existing Century 80-ton chiller and install a new air-cooled 80-ton chiller. The new system shall maintain equivalent performance using existing infrastructure, including glycol tank, pumps, piping, concrete pad, electrical service, and seawater heat exchangers. All work shall meet applicable federal, state, and local requirements. If none exists, all work shall meet industry standards.
