The strong hydraulics and climbing brackets allow the ACS Core 400 system to climb the core. The single stroke cylinder enables fast climbing.

The two-tower complex is now under construction in the River North neighborhood of downtown Chicago. Replacing a surface parking lot, together the buildings will stretch almost an entire city block and contain residential housing, retail establishments such as Whole Foods, a gym, and a restaurant.

The 2.2 million square foot mixed-use development will comprise of a 971 feet tall tower with an estimated 74 floors, referred to as Tower A, and a 574 feet high tower with approximately 49 floors, Tower C. When completed, Tower A with 276 rental units and 77 condominiums will be the city’s sixth-tallest structure. The towers, connected by a central podium, will both have lookout points with views of the skyline and will be distinguishable from other buildings due to their unique tapering shape and glass curtain wall.

Due to the free selection and adaptability of VARIO, it is being used to form the vertical shear walls, along with DOMINO, TRIO, and DUO panels. ACS Core 400 system is used for the construction of the core in both high-rises, to ensure quick and safe climbing. Additional safety of workers and the public below is ensured with PERI’s perimeter protection screens LPS (Light Protection Screen). The wire mesh screens allow natural light into the building while reducing wind loads.

Project Information

Tom Kruszewski

Superintendent

The project had an aggressive schedule requiring all 4 phases of the project to be constructed simultaneously, which required several unique formwork solutions. The construction sequence required a complicated core formwork solution that started in a forty-foot-deep earth retention system, various crane-lifted walls, and a complete perimeter of windscreens on both towers. McHugh Construction selected PERI Formwork Systems to supply and engineer the formwork that was instrumental in completing the project efficiently and ahead of schedule.
