8.9.1 The Contract must include a mechanism for assessing when availability has been restored. This can be done by technology, for example in the case of unavailability due to high or low temperature, by reference to a building management system measuring temperature. Alternatively, the monitoring personnel on the Authority's project management team may simply submit a pro-forma confirmation to the Help Desk. There should be an agreed procedure for both parties to be notified, particularly so that the Authority can where necessary confirm such availability.
