I would say we haven't had surprises, but there was a disappointment. We were hopeful that the shafts within the building would be sufficient to carry, for example, our mechanical and electrical.... They're much smaller than we were anticipating, which is causing us to drive to new solutions. We're still in the process of articulating designated substances in the building.
The most interesting discussion will be in terms of the structural work and assessments that we're doing right now. It's related to one of the upcoming decisions, namely, on how we will seismically reinforce the building. There are some opportunities around base isolation that would allow us to save a lot of the heritage hierarchy in the building and the structure that's above the basement in the building.
There have been no surprises from the perspective that we've got a very old building that requires a very significant modernization. Having said that, all of that allows you to do much more detailed planning for the design and costing of the program, which we're working on at present.
