Mr. David Gunning:

It is a big design issue. It is a technical commissioning issue. It is our job to make sure that BAM and its subcontractors gets every one of those rooms ventilated appropriately. As Mr. Devine said, we are 40% of the way along the entire commissioning process. We should be 60% or 70% along at this stage, but we are not, so there are some delays in that particular area. In a similar way, it is not just the air. There is also water in a hospital. Everyone is familiar with legionnaires' disease and the problems with that. Water is a critical issue. Medical gases in these rooms all have to work and have to be absolutely perfect, and because it is a digital hospital all the digital systems have to work.
