Mr. Phelim Devine:

That is the first thing. There are 1,200 smoke detectors and there are tens of thousands of these in the hospital that have to move. The second issue is that fire exit signs, like the one at the door of the committee room, are located in the centre. As there are so many components in the hospital ceiling, such as sprinklers, smoke detectors, text displays for nurse calls so in a crash they can get them, Wi-Fi points, DAS points, and cameras, some of those are obscured. It is a very hard thing to get right in a drawing. When they are physically put in, you look down and see that the text display is in the way. Therefore, they have to move. To be exact, there are 400 of those that are either moving and there are new ones being introduced-----
