This is a traditional approach that we've used on Parliament Hill. It really is a construction management-based approach. We've brought on the design team and the construction management team at the same time.
The key thing here with the Centre Block, as well as the other buildings within the precinct, is that there's a tremendous amount of heavy lift at the front end that is not really dependent on the design, such as taking all the asbestos out of the building, which is a couple of years of work, and doing all the excavation work.
For example, once we locked down the size of the Parliament Welcome Centre, we were able to get going on that in taking all of the asbestos out of the building and getting that done. We try to do things in parallel, rather than in series, rather than waiting to get all of the design locked down and then beginning the construction.
