NOTICE OF INTENET TO AWARD SOLE SOURCE

Cooling Tower Refurbishment and Replacement Electronic Proving Ground Facility

The Army Contracting Command-Aberdeen Proving Ground (ACC-APG), Fort Huachuca Division intends to award a sole-source contract under the authority 10 U.S.C. 3204(a)(1) and RFO FAR 6.103-1 - Only one responsible source and no other supplies or services will satisfy agency requirements to OBR Cooling Towers located at 3102 S 44th St, Phoenix, Arizona 85040. The requirement is for commercial fill replacement and service of two (2) cooling towers and replacement of tower a BAC tower and piping.

This creates a significant shortfall, as the current infrastructure cannot reliably of 11 climatic and dynamic test systems, and the tower for the RDT building is similarly past its service jeopardizing 4 agree systems. A failure of any of these cooling systems will cause an immediate shutdown of the associated test chambers, resulting in mission failure and significant downtime. meet the cooling demand required for testing.

Maintain a constant water temperature. Must have hydrostatic testing of piping, fan balancing, thermal performance verification, and control system validation at the Electronic Proving Ground laboratory facility. This is to include, but may not be limited to the following:

• Water Distribution System: check spray patterns, pressure, and alignment. Remove scale, algae and debris from nozzles and headers, replacing any clogged or damaged components.
