The Department of Defense, through the US Army Corps of Engineers, Omaha District, is conducting a Sources Sought announcement to identify potential sources for boiler equipment needed for three B-21 construction projects at Ellsworth Air Force Base, South Dakota. The procurement focuses on Advanced Thermal Hydronics (ATH) KN Series Boilers, which are preferred due to their suitability for the region's windy conditions and existing technician familiarity, with estimated costs for the equipment ranging from $25,000 to $400,000 per project, totaling approximately $600,000. This initiative is part of the integrated B-21 weapons system beddown and aims to enhance operational efficiency while adhering to DoD construction standards. Interested vendors must submit their capabilities statements by April 30, 2025, to Scott Dwyer at Scott.Dwyer@usace.army.mil.
