Famous Chicago Spire Cofferdam is Getting a Trim at 400 Lake Shore
The Chicago Spire cofferdam, idle since 2008 after the 150-story skyscraper’s construction came to a halt, is getting a bit of a hair cut. Thanks to 400 Lake Shore, the 72-story residential tower now being built on the site, the top “ring” of the cofferdam is being excavated and removed as part of the new tower’s foundation.
