Société des grands projets has awarded Webuild, in a joint venture with its French partner NGE (representative), a €1.38 billion contract (overall amount, of which 45.5% to Webuild) to construct Lot 2 of the Western section of Line 15 of the Grand Paris Express, the new metro of the Île de France region, representing the most important and innovative sustainable mobility project in Europe at the moment.
The new contract foresees designing and building four underground stations, approximately 7km of tunnels to excavate using TBMs and six functional structures included between the Pont de Sèvres and Saint-Denis Pleyel stations. Works will be carried out by Webuild in joint venture with NGE, Equans France and TSO.
The project's construction will be guided by eco-design principles and those for reducing the environmental impact of works during the construction phase and when they are used. Construction concrete with lower carbon content will be used, and more generally, materials with a low environmental impact will be chosen over others (i.e., bio-based, recycled, local and regional). Energy consumption control will be ensured with the energy recovery of the plants and technical equipment, and lighting and ventilation will also be optimised.
Line 15, which at 75km will be France's longest metro line, is a strategic project for Webuild, which has been present in France since the ‘90s. The line will circle Paris like a huge ring, with 36 stations that will cross 45 municipalities and four departments of the Île-de-France. Once complete 95% of the new lines will connect to the existing transport network, including Transilien services, RER, metros, tramways, and buses.

The Grand Paris Express aims to be a sustainable mobility option that will improve the life quality of the entire Paris area, also integrating the suburbs with the city centre. Overall, it foresees constructing approximately 200km of lines and 68 stations. The entire network will be built almost 90% underground and when finished it will transport more than three million people every day.
