Mike Doty, electrical engineer, USACE Alaska District, points out how congested the area is above the ceiling beams in the Long Range Discrimination Radar (LRDR) power plant during a tour of the facility at Clear Space Force Station with Bret Styers, senior program manager for the Ballistic Missile Defense Mandatory Center of Expertise at the U.S. Army Engineering and Support Center, Huntsville, and Col. Sebastien P. Joly, Huntsville Center commander, on August 16. The additional structural supports needed to protect the building and its mechanical and electrical components from blasts created an engineering challenge for USACE during the design phase, said Doty.
