The other issue with some of the engineering buildings, from what I understand, is that they are registered as "historically significant" buildings (or whatever the proper term is)... which means they can't undergo any major renovations. Or, at least, undertaking major renovations is difficult because we would be obligated to keep things historically accurate. The example I heard was that we can't even replace old single-pane windows with new double-pane ones - if a window needs to be replaced, it has to be identical to what's already there.
The other example I heard was that years ago, some alum offered to donate enough money to tear down Patterson (which needs a lot of work) and build a new, state-of-the-art engineering facility in its place but we couldn't agree to it because we aren't allowed to tear down (or fundamentally change) Patterson because of it's historical status.
