Mr. Robert Watt:

We have discussed this issue in detail. We have set out the position. The contracts committee had discussions with the national children's hospital board which came with a proposal and sought a derogation from the requirement for a lump sum contract. It sought the derogation, as Mr. David O'Brien mentioned, because of the complexity of the project. In setting out a detailed design for it and bringing it to the market to have a lump sum contract, there would have been not only very significant costs incurred in developing the design but also a time delay.
