Abstract:
The One Chicago project, about 1 mile (1.6 km) north of Chicago’s downtown loop, is being developed using the top-down construction method. The project will include a 78-story tower, a 50-story tower, and a podium covering almost an entire block, with four levels of parking extending 65 ft (20 m) below street level and nine stories of mixed-use commercial and residential space aboveground.
