The Cabin at the top of the mast forms the operational hub comprising the visual command upper deck, sub-equipment room, access gallery and rest and recreation facilities for on-duty NATS staff and plant.  The mast accommodates all the vertical circulation elements including stairs and two lifts (one internal and one external) as well as providing a service artery for mechanical and electrical distribution between the ground level and the Cabin.  The Base Building comprises a 3-storey building at the apron level which accommodates the primary plant, technical services equipment and NATS administration and support space.

The key challenge

The key design challenges for DSSR were the design of the environmental systems for the heavily glazed Cabin and the provision of M&E services meeting minimum NATS reliability and failure criteria. Extensive thermal and CFD modelling was undertaken to determine the optimum glass type, and air distribution and lighting concepts for both winter and summer extreme conditions.

Design of all mechanical, electrical, public health and fire protection services, with input from contractors and suppliers through BAA framework agreements.
