Checking out a caisson from above at GEMS World Academy Upper School.

The Upper School at GEMS World Academy Chicago has begun caisson work at 355 East Wacker Drive. Case Foundation is on site digging long, slender holes in the ground and then filling them right back in with rebar and concrete.

Originally issued a foundation permit way back in March of 2015, the GEMS Upper School got a new caisson permit on September 20. Designed by bKL Architecture, as was the first GEMS school, Power Construction will take build the school atop the Case’s caissons.
