Project Centurion

Located in one of the largest data center markets in the United States, the two-story Project Centurion encompasses 359,000 SF, including offices and 150,000 SF of raised-floor data halls. Together with a separate equipment yard, which includes a steel platform to support elevated generators and prefabricated electrical modules, the data center can deliver over 40 MW of IT power. The office component includes vertical circulation and loading docks.

A tight site, along with the existence utilities and major duct bank from a previous structure on the site, posed challenges to the design of the structure and required coordination for panel layout and material staging.

DeSimone’s engineers devised a steel-framed floor and roof, with a partial mezzanine around the perimeter of each floor level, as well as load bearing, tilt-up concrete wall panels for the exterior walls. The building rests on shallow, soil-supported spread foundations.

DeSimone’s tilt-up engineering experts played a significant role developing a design approach that involved assembling 90 tilt-up concrete panels—averaging 65 feet in height—cast-on-site with an intricate formliner to create a decorative reveal pattern and then placed by crane along most of the exterior walls.

Rooftop equipment is supported on rooftop dunnage enclosed by a steel screen wall.
