The CitiCorp Building, New York

Author: Joshua B. Kardon, S.E. 
University of California, Berkeley

This case is an excerpt from "The Structural Engineer's Standard of Care."


To accommodate a smaller building on the site, the high-rise CitiCorp tower was designed and constructed with its main columns at the middle of each side, rather than at the corners. The New York City Code, and high-rise structural engineering practices, required the building frame to be analyzed and designed to resist winds acting perpendicular to each face. Well after the building was completed and occupied, the design engineer reviewed the frame for adequacy against "cross-corner" winds. He found that based on that loading assumption, the building had a small but unacceptable probability of collapse. Work to strengthen the building was carried out. It was widely agreed that the structural engineer's performance was not beneath the standard of care. That is, the structural engineer exercised an acceptable degree of care and diligence, and therefore, the error was not professional negligence.

This situation illustrates the importance of a rapid response to the discovery of error, and the fact that even non-negligent errors can be dangerous and very expensive.
