HSU was the prime contractor on this project to upgrade the entire electrical system at the National Air and Space Museum (NASM). The museum remained open during this renovation and much coordination with museum and exhibition specialists was required to minimize the impact on the facility, exhibits, employees, and guests. Every area and exhibition was impacted, thus requiring complex staging and scheduling for shut-downs, testing, and tying back into building systems.

The scope of work included demolition, changing the panels, changing power link panels, relocating network protector, replacing and relocating switch gears US-C1, C2, E&W. Existing generators were demolished, removed and replaced; additional emergency generators were installed as well.

Other work included upgrades to the life safety systems, fuels tanks and piping, and the replacement of the A/C units in the elevator machine rooms.
