Yes, caissons are done, but not foundation work, on the RIU Plaza Hotel site at 150 East Ontario in Streeterville. W.E. O’Neil and crew are driving piles into the soil to help support the weight of the 28-story, Lucien Lagrange-designed hotel.

Hey, you know what we should be seeing soon here? Yep. Tower crane permit.

The lot that sat empty at 150 East Ontario for what seemed like an eternity is finally seeing action. Big action.

The RIU Plaza Hotel construction has begun in Streeterville. The City of Chicago issued a permit for caissons and foundation on July 19 for a 28-story, 390-room hotel. W.E. O’Neil is the general contractor. Lucien Lagrange Studio is the design architect. And that’s a big yellow Keller North America rig drilling caissons.

We stopped by in late July to have a first look at site prep, then headed back over this week to see the caisson action. And action we got. Very happy to see work started on this site.
