The concrete core of the 400 Lake Shore North Tower continues to rise, and all evidence of the cofferdam from the Chicago Spire dream has disappeared, at Lake Shore Drive and the Ogden Slip in Streeterville. The team of LR Contracting and BOWA Construction, along with concrete contractor Goebel Forming, are making great progress on bringing Related Midwest’s 72-story residential skyscraper to life.
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.
Chicago’s tower crane count to begin August 2024 took a slight dip from July, now that the machine that building Hyde Park Labs has been taken down. That leaves eight cranes in the air as summer continues. There is one pending permit, and it’s for Google’s Thompson Center renovation in The Loop.
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.
The tower crane erected in June at 1723 South Michigan Avenue raised Chicago’s crane count to nine to start July 2024. No cranes were taken down of the eight that were working the skyline in June.
