26 Days Ahead—Pandemic and All
The preconstruction process was fast-tracked to allow for the project to start construction while still finishing the final design. By fast-tracking the civil and structural design packages, it allowed us to receive substantial completion 26 days ahead of schedule, even during the COVID-19 pandemic.
VDC in Action
Between the project controls department, on-site field staff, and our trade partner coordination, the project benefitted from Virtual Design & Construction (VDC). By using VDC and BIM on this project, the below floor slab elements such as footings, piping, conduit, and underground ductwork were coordinated.

Additional Features
The new design-build facility replaced two buildings that the National Guard had outgrown, originally built during the Korean War. The front of the main building contains support features such as a fitness room, lockers, multi-functional classrooms, and a café area, while the rear consists of a carpentry shop, a machine shop, a canvas repair shop, communication shops, a calibration shop, an arms vault, and repair shop, an injector repair shop, and a radiator repair shop.
