99Percent Invisible had a good episode about the near collapse of the Citicorp building because of a design change made by the contractor that was really interesting.

The convention center in Pittsburgh has some massive trusses anchoring parts of the structure. They had a similar failure because a contractor swapped some less expensive nuts/bolts in place of what the architect spec'd.
