I will return to the statements that were made by Aidan O’Connell to this committee earlier in the year. Just from the witnesses’ reply, they said they were thoroughly investigated and no issues were found. That is correct, is it not? I just want to get my head around this. There is obviously a considerable gap between his statements, direct experience and direct knowledge, which I assume were absolutely made in good faith, and the outcome of the NBCMSO investigation. I am just trying to get a sense of it. Why could there be such a gap between a competent, experienced engineer and his direct experience and view that defective materials from quarries have been going into homes recently and the NBCMSO’s processes in terms of not finding any issues?
