Mr. Hugh Creegan:

The preliminary business case for the project contains all that detail, where we have set out the estimated expenditure on a year-by-year basis. That now has to go to the Government for a decision to be made. The detail will, presumably, be available after that, but it is all contained in the business case.

As for managing the expenditure, there are tight controls and governance arrangements in place on the MetroLink project. There is a project board in place, which comprises the NTA and TII officials, and TII's own board monitors what that agency does. Similarly, the NTA's board monitors what the NTA does in that area. There is an expert advisory panel, which provides expert advice, including from a lot of international experts in the area of tunnelling, metros and various other disciplines. On top of that, there is oversight by the Department of Transport, which has a major-projects governance oversight group in place. Within the governance framework, a lot of tools are in place to ensure the expenditure on the project is properly monitored and tracked.
