Mr. David O'Brien:

Simply, the authorisation was that the national children's hospital board did not have to use the standard public works contract. It was then up to the board to develop its own strategy. We advised and discussed. As the Secretary General outlined, there was extensive discussion on the matter. On the basis of the circumstances of the project, there was agreement, in principle, among the committee. It was not me making the decisions, there was much expertise around the table. That then is the basis of the derogation. We were satisfied a lump sum approach was not suitable in the circumstances.
