The Department of Defense, through the U.S. Army Corps of Engineers Seattle District, is seeking proposals for the construction of Unaccompanied Enlisted Personnel Housing (UEPH) Barracks at Joint Base Lewis McChord (JBLM), Washington. The project includes a sole source requirement for a Domestic Hot Water (DHW) CO2 Heat-Pump System, specifically manufactured by Lync, indicating that only this brand will be considered for the procurement.
