Jean Bouin stadium: preliminary consultancy
Rudy Ricciotti was awarded an architecture prize in 2007, and imagined a compact, asymmetric and undulating project surrounded by a finely perforated BFUP (Ultra High Performance Fibre Reinforced Concrete) mesh. It culminates at 31 metres where there are no buildings facing it, and it blends into the urban fabric losing more than half its height along Rue Nungesser et Coli. The building itself lies on the property boundary. It is in direct contact with public areas with no intermediate fences or barriers, while the dense design of the complex leaves space for a large square surrounded by trees adjacent to the Avenue du Général Sarrail.
The double curved surface of the façades and the roof was broken down into several thousand triangles about 8.30 meters long with base dimensions of 2.40 metres. Each of these prefabricated Ultra High Performance Fibre Reinforced Concrete (BFUP) triangles that are only 35 mm thick on the roof, is designed to be supported on a metal structure composed of 74 monumental spans. The number of perforations in these triangles varies depending on the location. They allow air to pass through on the façade and are closed with glass on the roof to protect spectators from the weather, while forming a sound barrier for the neighbours.
