BTW, don't know if I've mentioned it yet, but the FAA cleared the tower crane for the 230-foot addition to the back of One Campus Martius last month. The permit doesn't expire until March of 2020.

Perhaps the staging in the pit is for that? I'm not sure how these things work. I do know Bedrock announced they'd be seeking a foundation permit for the actual Hudson project next month, though.
