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. The objective of this project is twofold: one cooling tower is improperly matched to the test chamber it supports, leading to contamination that actively damages vital tests, while three other towers are over 20 years old and have surpassed their optional service life.
