Regarding the steel structure and the fact that we don't have accurate drawings of this.... Normally, you have as-built drawings with any engineering or architectural project. Is it the case that these just weren't done, or is it the case that they were done up to the standards of the day, which were different from what they are today?
I assume we can make the assumption that with regard to the recently completed West Block, and any other work going forward, there would be very thorough as-built drawings. I'm sure that our initial plans for West Block were altered at some point, in one or more ways, in the course of construction.
