This firm-fixed-price purchase order awarded by the U.S. Army Corps of Engineers (USACE) Walla Walla District to Trane U.S. Inc. is for the restoration of a heat pump/chiller unit at the Ice Harbor Lock and Dam in La Crosse, Wisconsin. The contract, valued at $92,436.33, requires Trane to replace worn parts and materials to bring the existing unit to the same level of reliability and technology as a new Trane chiller, as well as replace the control panel with a compatible, up-to-date system. This contract was awarded under simplified acquisition procedures, as the agency determined Trane was the only reasonably available source. The contract is not set aside for small businesses.
