Mr. Tom Costello:

It is a complex project. For instance, there are 5,000 km of cable, of all different sizes, and we have rates for each type of cable but the actual quantum of it was not fully defined in the documentation. It is now fully defined and, when we learned of the large increase, we sought an outside review to consider if we had over-designed the building. The feedback at the end of that exercise was that the building is fit for purpose for a modern, fully digital hospital. The quantities that have come out of that two-stage process are applied to the rates we got at tender in 2016 and that gives us the final cost. Does that deal with that question? In fairness, it is complex and difficult to understand because of the quantum but that is the nature of it. We set out on the journey of doing a two-stage tender, which meant that at the beginning, the rates, by their nature, were approximate.
