Mr. Chair, it's a very good question. I think we've developed a very robust costing methodology over the past few years. Essentially, in costing as well as scheduling we try to triangulate everything, which means we have our own in-house experts. We also rely on other sections of Public Works, the centre of expertise, to provide us with expert advice, and then we bring on specific cost specialists or scheduling specialists. Then we also work with our prime consultants. We ensure that we have a number of points, and if they are all lining up, we feel very comfortable with the costs or the schedule. It keeps everybody sharp. It's a challenge function to ourselves. We replicate both our costing and our scheduling every month. So every single month we produce a new schedule and new cost estimates for all of our projects.
