Lots of irons in the fire at the new McDonald’s HQ.

A foundation permit was issued by the city on November 7. Equipment from Michels Corporation (they did the caisson work on the newly-opened River Point Plaza) is tearing away at the soil in the block surrounded by Carpenter, Randolph, and Aberdeen Streets, and Washington Boulevard. Once that work is done, general contractor McHugh Construction will start going vertical with the Gensler-designed HQ.
