Mr. Kevin James:

It is a two-pronged approach. Again, it is public sector-private sector and the rules that cover quantity surveyors are that we work, go through a tender process, agree the programme with the contractor and the first stage will be the enabling works for the site. If there is a basement to be dug or concrete foundations, the concrete will go in quite early in the process. This comes down to whether it is poured concrete or block work. If contractors bring materials to site prematurely, there is a mechanism and agreement with the client as to whether we pay them in advance or not, or pay them for material stored on-site. There is a debate around - and the CIF can vouch for this - when the main contractor goes to the subcontractor and the manufacturer. It is whether the characteristics of the site allow you to bring the stuff on-site early or not and you agree a price with the contractor at the outset. If the contractor does not agree a price at the outset and decides after six months or a year on-site to negotiate a price, he may win or lose. He may have to pay more in an inflationary environment, as opposed to paying less. There is complexity to that. It is discretionary between different contractors and organisations. I do not know if Mr. Mahon wants to add to that.
