2. PROJECT DESCRIPTION

2.1 Scope: The contractor shall provide all labor, materials and equipment needed to expand the existing computer Server (Frame) Room, replace a computer room air conditioning (CRAC) unit, two (2) air cooled condensing units and associated DX cooling coils and refrigerant lines serving the Base Squadron Operations/Communications Facility, Building 164. Major work elements of the project are to:

A. Construct approximately 39 linear feet of new metal stud/gyp board wall to expand the existing Server (Frame) Room. The new wall system shall be installed from the concrete floor beneath the existing raised access floor, to above the existing suspended ceiling, to match the existing wall system as required to comply with security requirements.

B. Modify the existing suspended ceiling and raised access flooring systems in the existing and expanded Server (Frame) Room areas as required to match existing systems in the Server (Frame) Room and adjacent BNCC areas.

C. Cut two (2) openings on either end of the existing north Server (Frame) Room metal stud/gyp wall and install new doorways to access the expanded Frame Room from the existing Frame Room.

D. Remove the existing single R-22/Glycol CRAC system including the indoor unit and the outdoor dry cooler and pumping units and replace the existing CRAC system with two (2) new systems. The first new CRAC system shall be a dual cooling/economizer unit with R-410 DX and separate Glycol Economizer Coils and associated dry cooler and pumping units. The second new CRAC unit shall be an R-410A indoor DX CRAC unit, with associated outdoor condensing unit. Pour a new concrete pad adjacent to the existing equipment pad on the east wall of the Server (Frame) Room as needed to place the new CRAC condensing unit. Locate the new dry cooler/pumping units on the existing equipment pad serving the existing CRAC/Glycol system.

E. Add a new breaker and feeder circuit from the existing Switchboard EMSB in the South Mechanical Room to feed a new CRAC Panelboard in the new expanded Frame Room to feed the new CRAC systems in the Server (Frame) Room.

F. Replace the existing 3-pole, 208V breaker feeding the existing CRAC unit, in existing panel RP1D (located in the Radio Maintenance room adjacent to the existing Server Room), with three (3) new single-pole breakers. Run three (3) new 120v branch circuits with from RP1D into the expanded Server (Frame) Room to feed new isolated ground receptacles.

G. Modify the pre-action sprinkler system in the Server (Frame) Room by replacing a single, obstructed sprinkler head with two (2) new sprinkler heads.

H. Delegated design and install new circuits to support new servers.

I. Install leak detection system under raised floor as required by UFC 3-600-01.

J. Perform all other work as required to make the new expanded Server (Frame) Room completely useable and fully functional.

2.2 Special Considerations: The existing Computer Server (Frame) Room must remain completely operational throughout the duration of this project. The contractor shall coordinate closely with the ANG COR, Communications and Security personnel, and provide all dust control, temporary utilities, and take all security-related measures necessary to prevent any extended outages of the Server (Frame) Room and associated computer systems. The existing CRAC unit shall remain operational to provide cooling during the construction of the Frame Room expansion and installation of the first new CRAC system. The first new CRAC system shall be fully operational and capable of providing cooling to the new expanded Frame Room before removal of the existing CRAC unit can commence.

2.3 Government Furnished Property: There is NO Government furnished property provided for this project.
