Mr. John Conlon:

It is usual that the officials working on the project do an order of magnitude costing, which was done in this case, and work from there. As I said on a number of occasions, the order of magnitude costing was done with regard to the particular circumstances of conservation and with a design-led approach. It would be usual for officials on any project to do an order of magnitude costing to get some assessment of the cost and move forward from there.
