Mr. David Moloney:

Thank you, Chairman. The issues around the national children's hospital, as we are all aware, are very significant. There have been many issues around it. One of the issues is around how well defined the project was to begin with and, subsequent to changes in the definition of the project, one of the things that we have done, under the public spending code, is we have tried to bring much more clarity to those initial gates of decisions leading up to the tender process. I think that that is one of the major learnings from the national children's hospital and all that went on there.

As the chief procurement officer said earlier, there are circumstances where a two-stage procurement process may be advisable and, in particular, those circumstances might be where it is simply not possible to know how one wants to finally secure what one wants to secure without engaging in a first-stage process.
