Column forms are starting to protrude from the ground at 1326 South Michigan.
The full-build permit, issued July 24, 2017.
On Monday of this week, 1326 South Michigan received its full-build permit from the city of Chicago. That means crews from Walsh Construction can keep right on working at a frantic pace and start sending this one vertical. To the tune of 46 stories, to be exact. And within those 46 stories? 500 apartments, developed in tandem by Murphy Development Group with CIM Group, and designed by SCB.
Twitter user @ChrisAHorney, who works as MDG and last month clued us in to the tower crane being erected on this site, tells us today we can expect a name change for 1326 South Michigan in the coming weeks. And we always look forward to that kind of news.
As for that permit, The Big Green W didn’t seem to take much time celebrating its arrival; 1326 South Michigan is frantic with activity today, as you’ll see in the time-lapse video and photos below.

That tweet from Twitter used @skenrou Saturday morning confirmed the shiny yellow luffer (not fighter) was up and ready to do Walsh Construction’s heavy lifting. 1326 still looks like a barren lot, albeit with a tower crane now poking up through the north edge of the site. But that will all change quickly, as the 47-story tower can now begin to go vertical.
Shout-out to Twitter user @ChrisAHorney from Murphy Development Group, who let us know the tower crane stub spotted at 1326 South Michigan on Thursday, was planted on Friday. He also let us know full assembly will begin on Monday.
We’ve all seen Walsh Construction’s work around town, so it was pretty obvious they know a horizontal stub wasn’t gonna do them much good when building a skyscraper, but it’s nice to have photo confirmation anyway.
Walsh will put that tower crane to work erecting the SCB-designed 46-story, 500-unit tower that Murphy Development Group is bringing to the South Loop in partnership with CIM Group.

Yeah, it’s loud. If you’re anywhere near the South Loop, you probably realize that already.
Stalworth Underground continues driving the 360 H-Piles into the ground that will support the weight of 1326 South Michigan. This one can’t have caissons; the soil just isn’t meant for that type of foundation. Those H-piles will do the work instead. 46-story residential towers are heavy, apparently.

If you’re out searching for caisson work, don’t waste your time at 1326 South Michigan. The 46-story, 500-unit tower from Murphy Development Group and CIM Group won’t have them. Instead, the SCB-designed tower will sit atop H-piles, which Stalworth Underground is on site attending to now. According to Stalworth, the South Loop soil simply isn’t made for caisson work, so H-piles will be driven about 90 feet down into the bedrock.
How many H-piles does it take to support a 47-story building? 360, again according to the folks at Stalworth. Each pile is capable of supporting 350 tons, so that’s 252 million pounds of concrete and steel and glass and sofas and appliances that can be supported. Oh, and 190 cars. That’s a decent amount of weight there, too.
Stalworth started driving piles at 1326 South Michigan last week.
There’s enough topography on site now to make for a decent par-three golf course, what with the undulating mounds of soil, piles of rock and debris, and deep bunkers. There’s also a giant concrete block right smack dab in the middle of the lot that could present quite the hazard should you slice your tee shot.
