Mr. Damien Owens:

I might ask my colleague who is online, Mr. O'Connell, to come in on that one but I can confirm that, as Mr. Forde said, the Institution of Engineers Ireland has been asked by the NSAI to consult its members and to obtain their feedback vis-à-vistheir experience of observations on any damage to foundations. That work is under way.

It is important to note that the standard relates to concrete blocks. It is well defined. Concrete blocks are not usually found in foundations. The foundations are not looked at and there are reasons for that. I will hand over to my colleague Mr. O'Connell to deal with the query on the outer leaf.
