Case Foundation has moved their equipment onto the 145 South Wells construction site.

We figured 145 South Wells would be the first project stepping up to fill the tower crane void in The Loop. Hard to believe, but it’s been more than a year since The Loop’s last tower crane, at 151 North Franklin, came down from the sky. The only other potential candidate to put one up is 110 North Wacker, but we won’t see a tower crane there for some time yet. But this 20-story office tower from Moceri + Roszak should get the job done very soon.

145 South Wells received a foundation permit from the City of Chicago back in November of last year. And then last week, it got a tower crane permit. Case Foundation let us know a few weeks ago that caisson work would get started here soon, and sure enough, they’ve moved foundation equipment onto the site.

The new tower is a design by Thomas Roszak Architecture, who also designed the tower-crane-worthy LINEA Apartments at 215 West Lake Street. Clark Construction will serve as general contractor.

If you’re wondering where Clark has been in the Chicago Tower Crane Survey, 145 South Wells marks their return to our list, with their most recent entry being at 8 East Huron in River North. (You may also see Adjustable Forms markings on this crane. They’re serving as the masonry contractor, and that usually means they are responsible for the tower crane.)
