Like a 4th-line forward in the Stanley Cup Playoffs, Case Foundation goes to work in the corners at Essex On The Park.

Two weeks ago, Case Foundation started moving equipment onto the lot at 808 South Michigan Avenue, next to the Essex Inn. And now, they’re deep into full-blown caisson work for the new Essex On The Park apartment tower from Oxford Capital Group. Soon, the 56-story, 476-unit project by Hartshorne Plunkard Architecture will have footing to stand on, allowing Power Construction to get about the task of sending it vertical.
