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 PR.

1.1 BACKGROUND

The existing air conditioning system servicing the Weather Service Office (WSO) Yap main building is failing and at the end of its useful service life. The system is redundant and comprised of two (2) 10-ton packaged air conditioning units or Packaged Cooling Units (PCUs) .

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.

The Contractor must comply with all local and federal environmental, health, and safety regulations while conducting this work at the WSO Yap. In addition, the Contractor must ensure that all work and products are in compliance with applicable certifications/codes/standards (e.g., Air-Conditioning, Heating, and Refrigeration Institute (AHRI), American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), American National Standard by the American National Standards Institute (ANSI), American Society for Testing and Materials (ASTM), Environmental Protection Agency (EPA), National Fire Protection Association (NFPA), Underwriters Laboratories (UL)) and contract clauses.

2.0 SPECIFIC REQUIREMENTS/TASKS

2.1 Replace Existing Packaged Units

Note: The Operations (OPS) and Telecommunications/Power (COMM/PWR) rooms air conditioning system must remain operational at all times. Any outage must be first coordinated and approved by the onsite Facility Technician, with notification made to the Technical Point of Contact (TPOC). To minimize cooling outages, it is recommended that the packaged units be replaced individually to allow cooling to be maintained by the other unit.

2.1.1 Existing packaged unit equipment information.

Note: See Figures 1 through 4 for current layout and photos of existing equipment.

- PCU-1, Carrier Model 50TC-D12A1Q5A1A0A0, Serial 1513G10251, 208/230V, 3ph, 60Hz, R-410A

- PCU-2, Carrier Model 50TC-D12A1Q5A1A0A0, Serial 1513G10252, 208/230V, 3ph, 60Hz, R-410A
