If someone has more info on this I would like to know.

That's it? Are they going to be any subterranean components, parking, mechanical, subway connections, etc? 30 ft + 15 ft for caissons is nothing! Maybe the tower will go vertical in a short period of time. The Salesforce Tower here is digging around 60 ft (for 3 parking levels) and the caissons average 280 additional ft to reach bedrock.
