The Department of Defense, specifically the U.S. Army Corps of Engineers, Fort Worth District, is conducting a sources sought notice for Architectural Radio Frequency (RF) Shielding for three construction contracts at Dyess Air Force Base in Texas. The projects, which include a Flight Simulator Facility, Mission Planning Facility, and Alert Facility, require RF shielding materials that can achieve 60-80 dB attenuation across frequencies from 10MHz to 8GHz, while adhering to established performance and compliance criteria. This procurement is crucial for ensuring the operational integrity of the B-21 program, emphasizing the need for commercially available, non-developmental items that require minimal maintenance. Interested vendors must submit their capabilities statements by 3:00 p.m. CST on December 23, 2024, to the primary contact, Michael Fenwick, at michael.e.fenwick@usace.army.mil, or the secondary contact, Linda Eadie, at linda.d.eadie@usace.army.mil, as this notice is for informational purposes only and does not constitute a formal Request for Proposal.
