Thank you for the question, Madam Chair. I'll give a high level on that and then pass it over to my colleague, Ms. Garrett, who is responsible for the Centre Block program.
As far as establishing the cost and schedule go, we have a quite mature system within the precinct. The designers, as well as the constructors, develop costs and schedules. We have our own in-house experts. Then we have independent risk, cost and schedule experts and what I like to call “triangulation”. When our internal expertise and what we have coming from the designers and constructors lines up with the independent expertise, we feel quite comfortable that we've brought that to ground. When one of those points is out of sync, we drive that to ground until we resolve it.
That has been a tried and true methodology that we've used in the past to be able to deliver these projects on schedule. I know that there are a number of detailed, very important strategies that are being employed in Centre Block program. I'll ask Ms. Garrett to add some detail.
