Caissons are going into the ground where this lame old parking deck once stood, at 145 South Wells.

The Loop’s next tower crane is right around the corner, as foundation work has begun at 145 South Wells. Case Foundation, whose rigs we spotted on site a week or so ago, have started drilling caissons to support the 20-story office building from Moceri + Roszak.

145 South Wells replaces a modest four-story parking garage in The Loop, and will replace it with a measly 24 parking spots. That’s a pretty good trade-off.
