I would say that, in virtually any building, whether an old building or a new building, there is always some variance between the set of drawings and the building as it's built. I think the risks here are less, in the sense that the building is approximately 100 years old, so there are not the variations in construction quality and technique that you would find in a building built over 300 or 400 years.
However, I think we are doing a very thorough investigation right now, which includes investigations of all sorts of aspects of the building because, particularly in this case, it was an innovative building structure at the time to employ a steel frame and some masonry as well. It's really that interface we're going to be investigating carefully, especially because to create the seismic upgrade will involve very carefully studying how those joints and connections are made.
