Mr. Hubert Loftus:

We had the same structural engineering teams working on all the buildings to ensure consistency of approach. They had experience from the opening-up works in Tyrrelstown and work in St. Luke's national school and Ardgillan community college. That experience and knowledge of where precisely to open up a building was applied to the other opening-up works. It is a risk-based approach. Ultimately there will be more investigations to determine the required long-term solutions.
