The Mission Statement of the National Weather Service (NWS) is to provide weather, hydrologic, and climate forecasts and warnings, and impact-based decision support services, for the United States, its territories, adjacent waters and ocean areas, for the protection of life and property and enhancement of the national economy. In support of this mission, the NWS Pacific Region (PR), Facilities Engineering Branch (FEB), provides facilities support and maintenance throughout the Pacific Region.

The existing air conditioning system servicing the WSO Yap main building is failing and at the end of its useful service life. The system is redundant and comprised of two 10-ton packaged air conditioning units or PCUs (Packaged Cooling Units).

1.2 SCOPE

The NWS seeks to replace the packaged air conditioning systems PCU-1 and PCU-2 and also install a compatible new control system.

1.3 OBJECTIVE

Replace PCU-1 and PCU-2 with new equipment to match the existing equipment, and install a new control system to control both units.
