Mr. Tom Costello:

With regard to risk, as I mentioned, there are two major failures that have been identified in major, complex projects. One is when there is no collaboration between the different parties involved and it is all done on a contract basis. For example, the contractor may bid for a job potentially at below cost.

When one considers the turnover and profits of the top ten UK contractors, five were loss-making last year, in a boom time. It is an aggressive business. As Mr. Pollock said, it is a big attractive contract and many of the contractors are well skilled. They believe that if one enters into a contract with an inherited design, there are loopholes-----
