Pennsylvania Army National Guard Training Support Center


The nation’s busiest National Guard training facility, Fort Indiantown Gap, serves 130,000 warfighters each year. In support of the Gap’s mission of providing a full spectrum of combat training opportunities, Army National Guard officials have initiated major site upgrades. The replacement of a wooden World War II-era building with the new Pennsylvania Army National Guard Training Support Center creates a world-class facility to prepare Guard members for domestic and overseas assignments.

Gannett Fleming provided site development, geotechnical subsurface exploration, architectural, and other services for the replacement project. The team met the challenge of developing an aesthetically pleasing facility that achieved client goals while meeting the requirements of Department of Defense Minimum Anti-Terrorism Standards for Buildings. Sustainable strategies incorporated into the design enabled the work to build on the Gap’s nationally recognized environmental initiatives.

What We Did

To support servicemember training, the new center offers space for thousands of combat training aides, such as replicated weapons, munition rounds, and other devices. It features flexible classroom space, a video teleconferencing-enabled meeting room, break room, fabrication and repair shop, and a 30,000-square-foot warehouse. The structure’s insulated concrete forms, light-gauge steel trusses with standing seam roofing, and reinforced concrete slab on grade construction, along with blast-resistant framing, glazing, and doors, provide required security while creating a visually appealing appearance. Concrete curbs, segmental retaining wall, bollards, and access-control arms create and maintain a secure perimeter around the building.

Designed to achieve LEED Silver certification, the center includes daylighting and daylighting controls, enhanced thermal envelope performance, geothermal HVAC systems, 230kW of roof-mounted photovoltaic solar system, and recycled materials throughout. Site work included 10 acres of improvements, including pervious paving, stormwater detention, and anti-terrorism and force protection compliant landscaping that further advance sustainability goals.
