I am confident that, because we started early, we have done a lot of these surveys already. Quite a lot of the schools were involved at the beginning, so I am confident of that. I am also confident that the NHS has conducted surveys of its main buildings, and I think the courts have also done surveys. However, we have now increased the number of surveying companies from three to eight to make sure that we can get through all the cases, including any that Members are concerned about, as soon as possible.
