1201 West Lake caisson work is underway, as seen from the Green Line.

We’re still in the West Loop, and we’re still watching the goings-on along Lake Street.

Caissons are in the works for Twelve01West, the new seven-story office building at 1201 West Lake Street from McCaffery Interests. (You know them from The Lincoln Common project.) Revcon is on site as we speak, drilling holes into the earth just two blocks from another gig of theirs over at 180 North Ada. This time, they’re working with W.E. O’Neil, the general contractor on 1201 West Lake. This is familiar territory for W.E. O’Neil; their Chicago office is just a couple blocks away on Washington Blvd.

Designed by Antunovich Associates, Twelve01West got a foundation permit back in October, and a tower crane permit in January. The building will include 135,000 square feet of office space, and 11,000 square feet of ground-floor retail space, plus parking for 45 vehicles. McCaffery plans an early 2019 opening.
