Mr. Phelim Devine:

Yes. We worked very closely with our design team and brought in international expertise. Through that, we identified that it was an issue with the health technical memorandum, HTM. The current HTM will not work if you use a particular set of grills. We came up with a solution and BAM carried out demonstration and testing on site to help us prove that our solution was correct. That proved very successful and we then just issued the change order to change the 11 theatres from a square grill to a circular grill, which required only minimal works that were done in a matter of weeks and which cost circa €200,000 rather than €25 million.
