In november 2021, the client asked us the manufacture of 12 platforms used in the works of several piles in the construction process of line 18 of the Grand Paris Express, a project that will link Orly airport to Versailles-Chantiers. With a total of 10 stops, it will cover a distance of 35 kilometres, between underground and above-ground sections. It is precisely here that we find an overhead section consisting of a 6.7 km viaduct.

With a final weight of approximately 75 tonnes, the structures were manufactured according to the client's specific criteria, one of which was for the materials to be S355. It is important to note that the lead times were very tight with only 3 months to complete the manufacturing.
