The 1901 Project Scores A Tower Crane Permit As Caissons Roll Along

The 2026-2027 Construction Season is underway at the United Center, with teammates McHugh Construction and McHugh Concrete getting their game on for the first phase of The 1901 Project. Just called up specifically for this series is Stalworth Underground, whose rigs are on site drilling and filling caissons for a three-story mixed-use commercial building that will contain parking, retail spaces, and a new loading area, all covered by an occupiable rooftop deck.

The construction team has won three-out-of-four big permits for Phase 1. The first came through on March 25th, allowing for caissons and associated below-grade work to begin. They scored another victory with a permit for shallow foundations on April 27th, then followed that up by winning the tower crane permit on May 7th, completing the sweep on the home stand. The full building permit remains on the bench, waiting in the data portal since January 21st. Curiously, the permits specify that this project is a high-rise, a lofty goal for a three-story structure.

Southwest of the arena, at the northeast corner of West Adams Street and South Damen Avenue, what used to be the K parking lot is also surrounded by construction fencing, with some prep work underway. This will be the site of a 6,000-seat music hall. There are two permits pending for it in the Chicago Data Portal: A caisson permit, pending since October of last year, and one for shallow foundations & superstructure, which hit the portal on February 3rd. No full permit is pending yet. The caisson permit states clearly that this is not considered a high-rise.

Work on The 1901 Project is expected to last until 2040.

  1. I am simply not a fan of this “rooftop park” trend. The city needs to stop allowing that to be considered green space.

      Why? It’s a great use of space and reduces stormwater runoff

      • Because they don’t do anything to activate the street level, most people won’t know there’s a park there. What’s the difference between an industrial warehouse with a park roof and a parking garage and a park roof? None, both have blank walls at the street level and do next to nothing to encourage a vibrant street experience, which is the most fundamental trait of good urbanism.

          Agree to disagree. I’m of the opinion that *everyone* will know there’s a park here, because of the scope of The 1901 Project, because it’s next to the United Center, and because it’s next to the new music hall. It is also my opinion that more people will visit here for the park than will visit here to park their cars.

            Based on current experience in the South Loop and the near-West Loop, agree with all of Daniel’s predictions.

    • I think I understand your complaint for this specific location, especially with the way it will look driving down Damen. I do think rooftop parks are the right answer for certain areas of the city.

      I stayed in Nordhavn on a trip to Copenhagen and thought Konditaget Luders was one of the best ideas ever, especially since they had a grocery store and recycling center on the first floor. This type of model would be perfect in Fulton Market where there is a need for parking, green space, and grocery.

      • These are different than this rooftop park atop a parking garage. If the bottom were activated use with a park on top, that’s much much better. That’s not what this is. It’s a dead garage to store cars.

        • This project is replacing tens of acres of decades-old parking lots with far-better land uses. A couple of low-rise parking garages are a small price to pay for that, before we even get to the question of whether the rooftop park will work.

          Talk about letting the perfect be the enemy of the good, sheesh.

    • Bro’s never been to Millennium Park and it shows.

      Largest rooftop park in the world upon its debut and you wanna ban them? lol

      This dude hates fun.

      • From the renderings, it doesn’t seem like these are equivalent rooftop garage parks at all. Millennium Park doesn’t have any blank dead walls. By all practical purposes you can’t tell it’s a garage unless you’re looking hard. This seems like it’ll mostly be dead walls at the sidewalk level, so the park might as well not exist on top. If the park comes down to the street level in several places, maybe it’ll be good enough, but it doesn’t appear so.

        • “dead walls at the sidewalk level, so the park might as well not exist on top” — this statement makes simply no real-life sense.

        • The elevation facing the street is all blank for the most part. Shops and food in the main alley. For the sacrifice of all the parking lots, two blank walls along the busiest of streets is not bad. The backside of Merchandise Mart is far more hostile.

          The other two are… alright. Clean as far as parking garages go and the park remains close to the ground only being a level and a half up.

          This is privately funded and not intended to have the wow factor of our city’s main parks. It’ll be as authentic as the new podium for Sears Tower and Navy Pier’s facelift. The sloping ramp to the park level (if not VE’d) will easily get people from the concert venue and bridging to the park. Both High Line and Transbay parks get visitors in the millions and they’re only accessible by going up. Based on the renderings, this looks highly successful for an entertainment venue’s public space. They quite literally could’ve kept the roof blank

          Sounds like your problem is with the parking garage, not the rooftop park. Green roofs are an excellent way to manage Chicago’s storm water problem, and a park roof is even better because it allows people to utilize the space.

          Parking is necessary at some level for people going to events at the UC. This development is such an upgrade from the current surface lots.

  2. Is it just that the crane is classified as “high rise” because of the size of the garage, & the complexity needed for craning equipment to the far side of the site for both the loading dock & the rooftop planting?

  3. I can’t say I understand the vision based on the renderings. So there will be retail shops inside the parking garage? Oh well, anything is better than the parking lot desert that is the current state of the United Center.

  4. Here comes more displacement of long term residents… I dont live in the area and it’s going to be so crowded.

    • So let’s just never invest in our neighborhoods?

    • Displacement of which long term residents?

      Virtually all of the 1901 Project land is currently parking lots, and west of its footprint (across Damen) are more decades-old parking lots. North of it (across Washington) is a public park and some public housing none of which will be changed. South of it (across Adams) is a community-college campus and then an ice-rink complex, ditto. East of the 1901 Project footprint is a bunch of market-rate housing less than 15 years old, then the Whitney Young High School campus and some blocks of re$tored historic greystones and a large public park.

      Displacement of which long term residents?
