TRANSCRIPT

One thing that's interesting to us is we have to take out a few posts in situation - all the inactive bents in situ - so we have to devise a way to lift a bent up two inches, altogether at one time, so that, let's say, so that one sill can be removed and a new one put in. Now Gord's (Macdonald) done a lot of research into that because it's not an easy question to answer; a lot of structural engineers have looked at it and kind of scratched their heads and wondered how we're going to do it. We have relied heavily on historical documents and Gord has gone to and read these CN reports on how they did it. We will most likely use a very old technique to do it because, quite frankly, it's the best technique anybody's ever come up with. Now, that being said, we'll probably put our own little twist on it, with new materials and new technologies, but in the end, it's probably going to be an awful lot of jacks, slowly lifting it up one or two inches.

Kathryn: I think that was a problem that discussed when I brought a fellow named Gerry Flowers to the site...

Dave: Yeah, I recall.

Kathryn: And I think Gord has asked him about that specific problem.

Dave: And I believe Gerry had an answer for him in fact and although we haven't been able to put into practice and we don't know how it's going to work yet, the philosophy is based around the idea of what Gerry and some of the other workers on the bridge had, yeah, absolutely. Sometimes the simplest ideas are the best. But that being said, we haven't got to that phase yet, so it will be interesting to see how we adapt the old techniques to the new situation.
