Grand Paris Express is a massive project of about €30 billion that will greatly expand the public transport network of the French capital and its suburbs.

The project is part of the construction of the future Line 16 of the Paris Metro (Grand Paris Express), including the construction of ten stations and a line between Noisy-Champs and Saint-Denis Pleyel via Aulnay-sous-Bois to serve an area of 800 thousand residents. It will have a capacity of 200 thousand passengers a day.

​The future Line 16 of Grand Paris Express will serve a number of communes in the northern and eastern part of metropolitan Paris. The contract awarded by the Group, known as Lot 2, will involve the excavation of 11.1 kilometres of tunnel and the construction of four stations at Aulnay, Sevran-Beaudottes, Sevran-Livry and Clichy Montfermeil, along with 11 related works.

Webuild will assign 20% of the value of the contract to local subcontractors and employ disadvantaged workers for 5% of the total number of hours estimated to be needed to complete its section of the metro line.
