Mr. Phelim Devine:

The guidance document, which is a health technical memorandum published by the NHS in the UK, is what Ireland and the UK generally follow in terms of theatre design. It gives the option of either square or circular grills. I talked previously about us and CHI having an expert involved. Our design team engaged with that expert who said that in his view we should go with square grills, which we did. However, the guidance document says that those grills should ideally be located in a certain part of the room and they were not. When the final co-ordination of the theatre was done, they got moved out slightly. Then it was flagged as an issue.
