We would also expect that there would be an appropriate process of review, removed from the day-to-day function of contract administration. Our audit has been limited to establishing whether the contracts were established and let in a way that maximises their potential for delivering value for money. But, as these are in effect open contracts that will extend over several decades, the outcomes are difficult to predict. Many changes could occur and unforeseen circumstances arise. The project will need to be carefully managed to ensure that benefits are realised, and that costs do not escalate beyond expectations.
