Map of the Grand Paris Express network

French construction company Eiffage has won a �2.54 billion deal to design and build a section of the line 15 East of the multi-billion-Euro Grand Paris Express project.

Eiffage’s subsidiary Eiffage Génie Civil will work in consortium with eight architectural firms to design and build the section of line between Bobigny-Pablo Picasso and Champigny Centre stations in the east of the French capital.

The contract includes the excavation of 17km of tunnel, the construction of 15 related rail structures and two entrance structures, laying railway tracks, path facilities as well as high and low-voltage systems and electromechanical equipment (heating, ventilation, air conditioning, smoke extraction and fire safety) in the stations, tunnel and related rail structures.

The consortium includes Architecturestudio, Ar.thème Associés, fbcc, BIG-Silvio D’ASCIA Architecture consortium, LA/BA, VIGUIER, and Wilmotte & Associés.

Together, they will also be responsible for constructing six new stations: Bobigny - Pablo Picasso, Pont de Bondy, Bondy, Rosny Bois-Perrier, Val de Fontenay and Nogent - Le Perreux.

The consortium will also lead development works of the part of Champigny Centre station dedicated to line 15 East, as well as the construction of an operations centre in Rosny-sous-Bois and two property development projects in Bondy and Le Perreux.

Construction will involve the use of low-carbon concrete and the installation of fibre-reinforced concrete segments to reduce carbon emissions.

The landscaping of 15 hectares of green space has also been proposed over the entire project.

Work will start after a 15-month design phase with a view to handover in 2031 for its commissioning.

Eiffage has so far won 35 contracts for the construction of Grand Paris Express.
