Caissons are as done as caissons get at 145 South Wells, and now it’s time to start getting foundation work started. Which is exactly what’s going on this very minute in The Loop at Wells and Adams. Soon, this former parking garage site will start going vertical with Moceri + Roszak’s 20-story office tower.

We’re eagerly anticipating The Loop’s next tower crane, as it’s been a while since we’ve seen one in the heart of downtown. Then Clark Construction can start sending this tower skyward.

Speaking of not having tower cranes in The Loop, it’s been some time since we’ve seen Clark Construction with one of their own in the air. But suddenly, they’re about to have a glut of them. 145 South Wells got a permit for one on May 11, 110 North Wacker will require one, and the two buildings just getting started at 1415 South Wabash will be in need as well. Congrats, Clark! You’re about to have 3 cranes in the skyline!

Here are a few more caisson photos from Case Foundation’s work at the end of May, and a couple showing work on once-again-barren lot, as digging commenceth.
