It’s time to catch up on construction progress at the North Tower at 400 Lake Shore. The build team of LR Contracting, BOWA Construction, and Goebel Forming continues to make headway on the Streeterville residential tower, with concrete and rebar still dominating the site.
The City of Chicago issued a full building permit on August 6 to allow the 400 Lake Shore North Tower to continue construction through full height. The 72-story residential skyscraper from Related Midwest can now maintain progress unabated in Streeterville, as the concrete core continues its rise above the old Chicago Spire Cofferdam, and the replacement ramp from Lake Shore Drive takes form. There is also an incredible amount of excavation still ongoing at the site.
The famous Chicago Spire cofferdam continues its fade into oblivion, as the concrete core for the North Tower at 400 Lake Shore has cleared the top of the former hole in the ground. The core got some help, of course, in the form of a severe haircut for the concrete-and-steel cofferdam, which is being cut away piece by piece. The iron ring that appears in the photos below will be removed, leaving only the lowest portions buried deep in the ground.
One month after receiving a permit from the City of Chicago to complete construction, 220 North Ada progress has reached the underside of the fourth level. And on July 8, a permit for Phase 2 was issued for the project’s tower crane. That means once the concrete core has grown a little higher, concrete contractor Adjustable Concrete and GC Clayco will tie the crane into the core and insert a few crane sections into the “tower” segment for sufficient height.
Further details and renderings have been revealed for the first phase of the O’Hare terminal expansion. The renderings and plans are for the first satellite concourse to be located just west of the existing C concourse that is connected to Terminal 1. The project is being led by the Chicago Department of Aviation (CDA) along with SOM, Ross Barney Architects, Arup, and JGMA working on its design.
