I’ll go to the deputy for some specifics on that, but by way of example, on this particular contract we knew we were doing a teardown on a building and we knew we needed to know what the risks were in that building by way of contaminants such as asbestos and whatnot. The contractor we hired to do the assessment so that we would have the information that we needed to go out for proposal for tender on that project, missed a number of items which, unfortunately, resulted in a couple of the change orders. This isn’t something that happens to us on a regular basis. We usually get pretty solid information that helps us build our requests or tenders. In this case, some specifics were missing, but for the exact detail I’ll go to the deputy minister.
