Creation of a concrete canopy covering the transversal platform of Austerlitz station in Paris. The canopy is connected with the historical hall and the slab above Avenue de France.
The structure is a thin concrete shell (18 cm thick), for a maximum span of 15 m.
The shell is made with prefabricated parts connected by concrete poured on site. This allows to use a high resistance concrete (60 MPa), with higher density.
