The first and last one might be subsistence damage - sinkholes that weren't dealt with shifting the foundation. A parking garage in Allentown collapsed like that a couple years ago.

That simply points out a lack of following good foundation design. A tall building must have pilings that go to bedrock, or at least a certain distance down that would eliminate risk from all but the largest of sinkholes.[/QUOTE]

Good point.
