Mr. Chair, Ms. Sansoucy, we have looked at a number of hypotheses that were used to assess the value of one procurement model compared with another. In the case of the Champlain Bridge, a lot of the data was piecemeal. I'm thinking of the bridge's design, among other things. Hypotheses involving a level of design of 5% were used, when the standard is more around 10%. The department must have based its analysis on data that, inevitably, made the costs vary considerably.
Our conclusion is not that a public-private partnership necessarily costs less, but rather that studies should have been carried out before a decision was made.
