The 1001 South State residential development is located in Chicago’s Wabash arts corridor, within the South Loop neighborhood. The 510,000-square-foot, LEED Gold certified tower includes 38 levels of apartments with floor-to-ceiling windows, set on a four-level podium with a sixth-level amenity floor. The podium includes 248 parking spaces in an open garage.
The foundation system consists of belled caissons, extending approximately 65 feet below grade. To support the 5-level parking structure, we used one-way, post-tensioned slabs, supported on 60-foot long, post-tensioned beams at 20 feet on center. For the residential tower above the parking garage, irregular column spacing and slab edges made a post-tensioned slab system cost-prohibitive. Instead, we used a 9-inch, conventionally reinforced slab system. The tower is also rotated approximately 35 degrees from the parking garage, resulting in an irregular column grid. Through close coordination with the team, we were able to make the building column locations consistent throughout the structure.
