Potawatomi Expansion

In August 2008, Potawatomi Bingo Casino completed an expansion, tripling the size of the casino, adding a six-story parking garage, and creating a bridge connecting the structure to a nearby bridge. The three-phased project added 530,000 square feet.

GRAEF provided structural and mechanical, electrical, and plumbing engineering for the connector bridge and parking garage, and site/civil engineering for the entire project.

The first phase was a major transportation effort–constructing a connecting bridge to the James Groppi Unity Bridge and creating a new entryway to the property. The construction of a precast 1,800-car parking deck connecting to an existing parking structure was the second phase. A new road wraps around the back of the casino with a bus reception area and hospitality center. The final phase, construction of the casino expansion ran concurrent with the other phases and includes a valet-serviced underground parking lot.
