Ms Tracey Conroy:

We have indications from the reviews that have already taken place that there were issues with the checks and balances in place. We have commissioned an independent external review of the cost escalation. That is ongoing and will be completed by March. The concern - and the Government's concern - is reflected in that commissioning. That is about identifying weaknesses which will be addressed in phase B. In the interim the build board has identified actions which it is taking in terms of ensuring it will protect the guaranteed maximum price. I will ask Mr. John Pollock to outline some of them.
