We're not quite there yet for the Centre Block. The key strategy is to make sure we have really robust costing and scheduling so that we can report to Canadians and hold ourselves to account on that.
The key thing there will be emptying the West Block and really starting to do.... We know a lot about the building, but we need to do a detailed investigation of the building's conditions, which will include opening up floors, walls, and ceilings to really get at the full scope. That will, of course, then drive a precise scheduling cost.
