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.

Enjoying the photos? Metra and CTA rides (and Amtrak trains to Milwaukee), Zipcars, Divvy Bikes, camera lenses, domain fees, snacks & energy drinks, and comfortable walking shoes add up. You can help offset expenses by making a greatly-appreciated donation to Building Up Chicago.
