Structural Integrity.

The columns of the Citicorp center can't be built on corners because of the St. Peter's Church was in the way of the place that one of the corners needed to be built. If they built the building without that corner, the design of the entire building would be flawed. However, they decided to built the church anyways, just around the church. The biggest flaws that the Citicorp building had was that the columns were very unstable, the exoskeleton was way too light, and the quarterly winds that would attack the corners. The quarterly winds could literally blow the building away and this could happen with in the first 16 years of it being built. This is scary to think about because so many people could be injured if this were the case. The person who found this flaw out was named by an undergraduate student studying the building. He shared this information with the main architect of the project Joe Morgenstern.
