Confidentiality and efficiency for an RAF training school



The RAF was seeking to build a specialist facility to deliver training for the crews of the new Airbus A400M. Based at RAF Brize Norton, the training school would house two full flight simulators, teaching spaces, offices, a mission planning rooms, changing rooms and break-out areas.



Confidentiality is important on all projects, but particularly so for work in the defence sector where much of the information is classified. At Brize Norton, for example, some areas of the building featured tight restrictions such as the IT server rooms adjacent to the simulator halls.


The building’s ceiling voids posed additional challenges. The sealed nature of the building meant extensive ventilation ductwork in most corridor ceiling voids, around which the electrical containment had to fit. The several security levels for data required separate trunking for each, thus increasing the number of containment runs.


Furthermore, the client had targeted a DREEAM ‘Excellent’ rating, which added challenges on the lighting design.



Client confidentiality is a given on all our projects. We have built a proven reputation for trustworthiness in the defence sector and this supported our work in the classified environment at Brize Norton.


We provided detailed electrical design services including lighting, small power, data, fire alarm and security. We paid close attention to the lighting design – as this project was pre-LED, lighting efficiency was achieved mainly through daylight dimming and presence detection.


Our team identified indirect routes so that cables did not run through restricted areas. In some instances, this required sub mains cables twice as long as they would normally be in more regular environments. To ensure efficient trunking routes in the ceiling voids, we worked closely with the company responsible for the mechanical services and also provided a detailed cable model using Hevacomp.



The RAF is now benefiting from a facility able to deliver tailored training on its Airbus A400M fleet at Brize Norton. Not only does the new training school provide a high quality learning experience, it has also successfully achieved a DREEAM ‘Excellent’ rating.
