Description

Built in 1972, this stadium was demolished and rebuilt within the scope of a global urban redevelopment project. It was officially inaugurated in January 2014. The spectacular sand dunes in the Rio Grande Do Norte region - one of Brazil's 27 states - inspired the design and construction of this new undulating sports infrastructure. Its architectural shell made up of 20 petal-shaped modules allows perfect thermal and acoustic insulation, while offering better ventilation and facilitating the natural light contribution. The stadium has a capacity of 42.600 spectators. Due to the resizable structure 10.600 seats will be removed after the World Cup.
Architects Ben Vickery and François Clément have banked on the installation versatility through implementation of a custom, flexible, lightweight structure. More than a stadium hosting an international competition, the Arena das Dunas is a real endowment for the Rio Grande Do Norte region. The multi-functional nature of the stadium ensures its hosting of many socio-cultural, sports, leisure or business events.

Tensioned ceilings made of Précontraint 1002 T2 composite material installed under 20 asymmetrical petals forming the stadium roof: A veritable engineering challenge since none of the 20 modules is of the same size or has the same curvature. In addition to its thermal and acoustic insulation performance, the visual comfort offered to the spectators, the design "in movement", hugging the steelwork outlines, the structural strength and dimensional stability of the Serge Ferrari composite membrane makes all the difference here!
