Cité de l'air building
14 of the 17 floors of this 62-metre tall building are now clad in stainless steel. Viry has been awarded the contract to create the shading devices, structural steelwork and the metal roofing. The shading panels (4,500 m2) are grids made from triangular section wire. They are deployed at a variable angle along the curved 90-m long façade. Extreme precision was required for the fabrication of the resulting curved surface and particular care was needed in handling this noble material which is sensitive to deformations due to welding.
28 tonnes of stainless steel were used. Tower “F” will be situated at the heart of the future Defence Ministry – the famous “French Pentagon”.
