Mr. John Wickham:

I referred earlier to the involvement of the harmonised standards system. Within the scope of the framework of the construction products regulation, we have ensured that Ireland, as opposed to Northern Ireland, will apply third-party oversight to materials where problems may occur. That means each economic operator receives an independent audit from a notified body such as the NSAI, among others. There are upwards of ten notified bodies operating in Ireland. That gives reassurance around the factory production control with regard to the production of the aggregate and is intended to ensure that the means by which it is produced leads to a credible declaration and performance. Ireland is unique in how it has responded with a level of oversight behind the factory gates. That gives more credibility to the marketplace, reinforced with measures by the National Building Control Authority. The focus on this risk of construction products and market surveillance in this area are important.
