The €1.087bn contract for the Grand Paris Express covers the underground section from Saint-Denis-Pleyel to Drancy-Bobigny station.
The contract includes the excavation of a tunnel of approximately 5.5km, upgrading of 2.5km of existing tunnel, construction of four new stations – Stade de France, Mairie d’Aubervilliers, Fort d’Aubervilliers and Drancy-Bobigny, construction of four new service structures and upgrading of three existing service structures. The consortium will also build housing and offices above the Mairie d’Aubervilliers and Drancy-Bobigny stations.
The Iris consortium comprises Bouygues Travaux Publics, Bessac, Soletanche Bachy France, Egis, Colas Rail, Alstom, and architects Atelier d’Architecture Brenac & Gonzalez & Associés, Atelier Novembre, Atelier Schall Architectes Associés, and Enia Architectes.
Iris says it has paid particular attention to the architectural design and choice of materials for the project.
It is also committed to reducing the project’s greenhouse gas emissions so will prioritise the reuse of materials, the use of low-carbon fibre-reinforced concrete for the tunnel segments, and the use of electric vehicles and site machinery. A waste reduction initiative will be put in place on the construction sites.
The consortium also says it plans to contract at least 20% of its work to SMEs.
Line 15 East is scheduled to come into service in 2031.
