We have a number of different mechanisms to exercise control and accountability. One is obviously the competitive nature of the marketplace in general, and we monitor very closely the number of bids we get in. We do our own estimates of the cost of the work before we put it out on the street, and we compare the tender prices against what the estimates were. If there is a variation--either over or under--we have a review of the basis for those variations.
In many cases, we have a fairness commissioner who is a part of the procurement process and independently does a report to us and to the board about the quality of the procurement we actually went through. We have internal auditors as well as external auditors who come in and give us a review on an ongoing basis. We also have the provincial Auditor General, who comes in and sees us on a periodic basis.
