Statement of Work FY23 CARES Act Project (NOVA)

Multiple Federal Buildings, Seattle, WA 02/22/2023

1 GENERAL REQUIREMENT

Contractor is to supply all time, equipment, and materials to accomplish the evaluation and adjustment of individual HVAC system compliance. The contractor shall conduct the work with staff that are NEBB Test & Balance Certified.

The purpose of this effort is to provide testing, adjusting, and balancing services at the air handler level to ensure outside air requirements are achieved.

The contractor may be required to force the HVAC system into cooling mode as well as the heating mode to determine the optimum AHU supply fan and return fan speed settings. This will require overriding the building automation system (BAS) settings to call for heating in each zone as well as conducting the operations in a cooling mode to establish the proper fan speed settings. Contractor shall be responsible for coordinating with the GSA O&M Contractor to make any BAS system adjustments necessary to conduct the work.

This project includes the following five buildings -

1.1 The Nakamura U.S. Federal Courthouse (WA0035ZZ) is located at 1051 6th Ave, Seattle, WA 98104. The Nakamura Building was built in 1940. The existing building is a thirteen story building with approximately 170,000 gross square feet. The building HVAC system includes ten air handlers, AHU-1 through AHU-10.

1.2 The NARA Building (WA0059ZZ) is located at 6125 Sand Point Way NE, Seattle, WA 98115. The NARA Building was built in 1963 and is approximately 202,000 gross square feet. The building HVAC system includes seven air handlers - AHU-1 through AHU-7, however this scope is limited to AHU-1, AHU-2, AHU-3 and AHU-4.

1.3 The Federal Office Building (WA0036ZZ) is located at 909 First Ave, Seattle, WA 98104. The construction of the historic Federal Office Building was completed in 1932.

The building is 11-stories with approximately 52,000 gross square feet. A major HVAC system renovation was completed around 1992. The building HVAC system includes four air handlers - AHU-1 through AHU-4 all of which are supplied by 100% outside air.

1.4 The U.S. District Courthouse (WA0102ZZ) is located at Stewart St and 7th Ave.

Seattle, WA 98101. The U.S. District Courthouse was built in 2004. The existing building is twenty-five floors. The building HVAC system includes sixteen air handlers, AHU-1 through AHU-16).

1.5 The Jackson Federal Building (WA0101ZZ) is located at 915 Second Ave. Seattle, WA 98174. The Jackson Federal Building was built in 1974. The existing building is thirty-seven stories tall. The building HVAC system includes seventeen air handlers, (AHU-1 through AHU-17).
