Exposed-steel bracing and a glass curtain wall create a striking exterior for the industrial structure. The “X” bracing on the factory’s exterior not only forms part of the lateral system, but also makes a dynamic visual statement. A steel canopy projects at roof level, covering entry and loading dock areas. The three-story lobby features 50-foot-tall vertical trusses to support the roof loads and the exterior glass curtain wall.
The factory building is 650-feet by 450-feet in plan with the manufacturing functions housed in a one-story area and office areas located in a three-story, front section. Thornton Tomasetti chose a 40-foot by 40-foot column grid to create an open floor for the factory, while maintaining structural efficiency. In the office area, columns were introduced at 20 feet on center to help minimize beam depths. Three expansion joints divide the structure, creating the need for an independent lateral system for each section.
With its stunning aesthetic, the factory played a major role in revitalizing the Goose Island industrial area.
