Madrid Barajas Airport's new terminal was awarded the 11th Royal Institute of British Architects Stirling Prize on Saturday. The £450M terminal was designed by the Richard Rogers Partnership with Estudio Lamella.
Structural engineering was carried out by an Anthony Hunt Associates, TPS and OTEP/HCA joint venture.
Spanish firm UTE was the main contractor and Arup aided as façade engineer.
Barajas is now the largest airport in the world by area, with a total floor area of 1.12Mm 2, a third greater than Heathrow's Terminal 5. It opened in February, doubling the airport's capacity to 35M passengers per year. The unique undulating seagullshaped roof sections are supported by 14mm thick hollow pipes, which are 800mm by 480mm at the base and 480mm by 200mm at the head. Each 72m long seagull wing is 500mm by 30mm in section.
