Certainly, and I agree with the other witnesses that it really would be project specific, that there are things that would suit some projects more than others, and some that might be unique to a special project.
The area of sustainability is an interesting one in terms of toxic site cleanup. Sometimes that's one of the issues that we deal with, but it's also in terms of sustainable practice, and adaptive use of buildings on site rather than just knocking things down. Can we be sustainable in terms of reusing that material?
Those are the hard things, but there's also all the benefits in terms of employment and skills development as well.
