A rendering of 110 North Wacker, which received its foundation permit from the City of Chicago Monday, from Goettsch Partners.

A foundation permit was issued Monday for 110 North Wacker, the 54-story office tower that will replace the now-demolished (and much-photographed-in-the-process) Morton Salt Building. Case Foundation will be out on site in the very near future, handling the foundations alongside general contractor Clark Construction.

All yous up there in the surrounding high-rises, get those demolition cameras down, put up your construction cams, and be ready to send in your bird’s-eye views!
