The tower crane is real. And it is spectacular.

The stump has been planted, the foundation poured and cured, and all the parts are assembled in mid-air. The tower crane at Centrum Hubbard and 412 North Wells is ready to go.

That single tower crane will erect both the 9-story office building (412 North Wells) and the 23-story, 193-unit residential tower (Centrum Hubbard) in the lot at Wells and Hubbard. Both buildings were designed by next-door neighbor Hirsch Associates. And with it now in place, it’s time for digging some foundations. Not by the tower crane though. The excavation equipment will handle that task.
