The following factors were taken into account in determining the size of Regional Control Centres.
Each Regional Control Centre is part of a resilient network. It has been designed to deal with both its own workload, whilst also providing extra capacity to take on the work of other Regional Control Centres should they, for whatever reason, become overloaded or unavailable. Each building will contain a large control room, operations room, emergency planning room, and space to accommodate other staff or agencies as required for large scale incidents.
Each facility is designed to be self-supporting for seven days, and has been designed to incorporate uninterruptible power supplies (UPS), generators and fuel storage, with the ability to replenish fuel supplies from outside the secure area. Each also has significant water and effluent storage capacity.
Regional Control Centres will provide space for training new personnel, meeting rooms and provide adequate staff facilities, such as, canteen and locker rooms. Each building will also contain space for building services machinery and the main IT equipment room.
The Regional Control Centres have also been designed so there is capacity in the network to accommodate future growth in demand for call handling.
