Each facility contains specialized one-of-a-kind laboratory testing equipment that required detailed coordination and communication with HERD scientists to address concerns regarding vibration and explosive separation. The design required acoustical analysis and the mitigation of vibration from low-flying, low-frequency emitting aircraft, as well as sensitive equipment isolation and evaluating vibrations due to intentional detonations. This was achieved by using heavy mass walls and roof construction in the structure design. Additionally, various pieces of laboratory equipment required heavy mass foundations to prevent transmission of vibrations to adjacent laboratory spaces. Extremely sensitive equipment was isolated using environmentally controlled enclosures to mitigate vibration, acoustics and electromagnetic interference.
