The Department of Defense, through the Air Force, is seeking commercial services to support the expansion of test capabilities at the Arnold Engineering Development Complex located at Arnold Air Force Base in Tennessee. The primary objectives of this procurement include the reactivation of a large industrial-grade heater to operate alongside an existing unit and the installation of a ducting system, complete with valves and hydraulic skids, to effectively channel heated air to the test cell. This initiative is crucial for enhancing the government's test facilities and ensuring stable conditions during testing processes. Interested contractors must submit their responses, including company information and technical capabilities, by October 11, 2024, to Brooke Vandeman at brooke.vandeman@us.af.mil, as this notice serves as a Sources Sought announcement rather than a formal solicitation.
