Aile Est (East Wing) of Genève Aéroport is a new terminal replacing the previous 1970s building. The building is 520m long, 19m wide and 10m high. It comprises repeating 20m-long structural steel modules, supported every 20m on inclined steel columns that lift the whole structure 6m above the airfield roadway, allowing vehicles to pass underneath. Each departure gate is 80m long and consists of four structural modules. The steel structure is overtly expressed as an integral part of the design, giving the building a clean, unencumbered, contemporary aesthetic. Maze Fire personnel worked closely with RSH+P in conjunction with Atelier Jacques Bugna SA to develop a comprehensive structural fire engineering study (drawing together analysis techniques such as radiative heat transfer, smoke temperatures, smoke movement, structural member size and fire limit state loading). The analysis was carried out to optimise the fire protection requirements for the steel structure and to carry this through successfully to completion it was necessary at all stages to engage closely with the local Regulatory Authorities and Fire Engineer to align the precepts of the analysis both to best practice and Swiss codes and ensure that the proposals were consistent with the holistic fire strategy design.
