The BAE Filton 7 acre building was re-roofed, while RAF and USAF combat aircraft were being maintained at shop floor level.
NSS erected mobile access rigs off the spanning tracking at a 20m level to allow the roof work to proceed.
The system used trackways and material distribution trollies on the outside of the building, and a complete waterproof membrane of netting and sheeting.
In the words of BAE, 'not so much as a cigarette packet fell to ground level'.
