The Department of Defense, specifically the U.S. Army Corps of Engineers - Omaha District, intends to issue a Firm-Fixed Price purchase order for maintenance services on the Gavins Point Hydro-Optic Ultraviolet (UV) Systems located in Crofton, Nebraska. The contract will involve semi-annual maintenance of two UV light systems to control zebra mussel infestation in the raw water unit cooling system, with the work being performed exclusively by Atlantium Technologies LTD due to proprietary rights. This non-competitive acquisition is justified under 10 U.S.C 2304(c)(1) and FAR 13.106-1(b), as only one source is deemed reasonably available for this requirement. Interested parties must submit any evidence of capability by 2 PM CDT on March 26, 2025, to Marc Proietto at marc.proietto@usace.army.mil, as no solicitation will be posted and the government will proceed with the award if no competitive responses are received.
