Revcon has caisson work well underway at 3Eleven.

Sit back while I tell you everything I know about the goings-on in the 300 block of West Illinois Street in River North.

At 311 West Illinois Street, the John Buck Company is putting up 3Eleven, a 25-story apartment tower, in what used to be the parking lot of Assumption Catholic Church. The FitzGerald Associates Architects-designed building will boast 245 “luxury” rentals, 3,000 square feet of retail, and 109 parking spaces, some of which will be set aside for the exclusive use of the church. Power Construction is on the build, and Revcon Construction is revving up the caissons as we speak.

Separately, on the other side of the church, a one-story addition is being added to the priory building. That is a project designed by McBride Kelley Baurer Architects, with Norcon, Inc. of Chicago handling the general contractor duties. I’d show you photos of that work, but there isn’t much to see. The action is all at the east end of the block.
