The National Geospatial-Intelligence Agency’s new western campus is an impressive landmark in the St. Louis Place neighborhood at Jefferson and Cass Avenues. Replacing a century-old building, the development includes a Secure Analysis Facility, two parking garages, a visitor control center, a remote vehicle inspection facility and a central utility plant.

USACE’s Kansas City District led delivery with the McCarthy Building-HITT Contracting design-build team, integrating project planning, design and construction. As the civil trade partner, Castle performed the enabling sitework, making way for vertical construction.

The $26 million civil scope connected the campus, installing water and irrigation mains, sanitary and storm sewers, and campus conduit, while executing structural excavation, soil stabilization, and comprehensive SWPPP controls to maintain compliance on the secure, multi-phase federal site. In all:

• Roughly 600,000 cy of mass grading shaped building pads, circulation routes and utility corridors.
• Six runoff holding areas and bioretention features now capture, treat and return stormwater for landscape irrigation and mechanical cooling.

Construction finished in 2024, with full operations expected in 2026. The campus advances NGA’s mission with environmental, cost, and policy advantages; expands partnerships with universities and technology focused organizations; and improves recruiting through proximity to data facilities and the region’s workforce.
