It’s been nearly three weeks since I’ve given you an update on 400 Lake Shore North Tower construction progress, and for that, I apologize. The concrete core has gotten a little taller, and there isn’t a single shred of evidence remaining of the Chicago Spire Hole. What I’d call the “sub-basement floor” or whatever the proper term is for the lowest floor of the tower, is poured, and there’s rebar sticking up and lying down everywhere. And I don’t know what that embankment is all about at the north end of the site (parallel to Ogden Slip) but even that’s cool as heck.

Let’s get to the photos. This is progress as of 09/10/2024 by general contractors LR Contracting and BOWA Construction, and concrete contractor Goebel Forming:

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.
