So there's no real structural reason for an underground foundation in Chicago? I'm just asking because the Study Hotel and Rubenstein Forum are side by side, as you know. They spent months digging out the foundation for the Rubenstein, but the Study Hotel is just as tall, or so it appears, and yet they built it at ground level.
Maybe this changes for a tall skyscraper but I guess at lower level you can get away with a ground level foundation.
I ask this as a layman. I'm not in the contraction business and don't really know the engineering considerations.
