It took <check’s sun dial> less than two weeks for Power Construction and Stalworth Underground to get caissons drilled at 920 North Wells. I’ve left dirty dishes in the sink for longer than that. Regularly. But there’s no time to be wasted on JDL Development’s latest endeavor, the North Union mega project, so it’s out with caisson equipment, and in with the earth movers. They’ve got a foundation to dig out, not just for the building, but also for the tower crane, and Manitowoc MD485 to be precise, which received a foundation permit of its own on Tuesday, May 17.
Since I once again fell asleep on the job, the following gallery includes photos of caisson work taken May 12, and post-caisson work taken May 19.
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.
