Mr. Aidan O'Connor:

No; the supplier will have ways of substantiating the statement being made. For example, where a person is on site and sees something, perhaps in someone else's work or a pre-assembled item, he or she will need to have documentation to back it up. A series of documents will be required. One does not want people to provide a bundle of material. Instead, we want to have a clear certificate indicating who signed off on the work, his or her competence, the work in which he or she was involved and the areas he or she supervised and for which he or she takes responsibility. The assigned certifier and builder take responsibility at the completion stage when they both sign a common certificate. There is, therefore, no excuse in terms of who is responsible.

Who was responsible for the poor electrical installation at Priory Hall?

We know there were people who then said it was okay. They were irresponsible but we then try to find out who was responsible for it. There must be a level of responsibility in any procedure, and this is where we are requiring it. In referring to self-certification Deputy Kenny seems to imply that is an easier form, but it is not; it will be meticulous. The code of practice in that will spell that out. A checklist of the inspection regimes required will be prepared in advance of construction starting. Some of them will be periodic and others will be at milestone stages - that is, at certain stages of construction.
