Mr. Richard Butler:

I will address the question about buildings taller than 10 m. Part A of the building regulations requires disproportional collapse designs in the event of explosions in purpose group load risk residential buildings of up to four storeys. Purpose group 2(a) comprises buildings of above four storeys. These can be onerous calculations. Another issue is the competence of the designers and builders involved in these multistorey timber frame buildings.

We do not have that many people in Ireland who have designed skyscrapers and would be competent to actually undertake even a concrete one, and we are going to that high-rise. They have to be mindful of their limitations on the design and state that they are competent to do all of this work. In addition, they have to be trained and have the knowledge of the construction materials. That is in all aspects of building regulations from A to M.
