The highs and lows of One Grant Park include below-grade core work, and preparations for building a tower crane. The tower crane base was planted Friday of last week, so the foundation has had time to set up properly. If I had to guess, I’d say they’ll put it together over the weekend. There’s plenty of room to work within the site, so street closures don’t seem likely.
Meanwhile, grab a stepladder and go watch the work at the east side of One Grant Park. Workers are deep down working on the elevator core. And they’re using fire!
