Ms Jenny Fisher:

There are different pots within the contingency figure, so it depends on whether it relates to labour, materials, additional ducting from Eir etc. There are a number of assumptions that were baked into the financial model at the bid phase. If we had not got those contingency pots, that price would effectively have been locked in as part of the fixed price. It was a clever mechanism from the Department's point of view to ensure that those costs would only be payable in the event that they actually arose. Where there are unders or overs, we go through that process with the Department and its advisers and there is an independent certifier who signs off on them. It is only to the extent that there was actual evidence of those costs being incurred that we would tap into those contingency pots.
