I assume the rationale for phase two of the visitor welcome centre being the first thing on your agenda is that the work that's going on in Centre Block initially for the first couple of years is not the heavy structural work that will be needed later on. It's a matter of figuring out what's there, removing items that are there. You're trying to do multiple things at the same time. I assume that's the logic of it.
If the visitor welcome centre or parts thereof were started later, thereby allowing us to figure out what should and shouldn't go out there, is it possible that either the amount of time the visitor welcome centre hole is in the ground or the amount of ground that's being dug up at any given time could be reduced, or some combination? I mean some part of the footprint being not dug up for all or part of the period and perhaps the period during which all or part of this being dug up being shrunk.
I worded that in a way that's difficult to answer, but I'll leave that with you.
