Vinci Construction wins contract on Line 15 South of the future Grand Paris Express transport network

The joint venture made up of Vinci Construction, a global player in concessions and construction, associated with Spie batignolles, a large French construction and services group, has won a major Grand Paris Express contract. Société du Grand Paris selected the bid submitted by this joint venture to build the T3C section of Line 15 South between the Fort d'Issy-Vanves-Clamart and Villejuif Louis Aragon stations. The €926 million pre-tax price covers construction of a tunnel with a length of more than 8 kilometres by means of two 10 metre diameter earth pressure balanced tunnel boring machines. It also includes construction of five new stations (Châtillon Montrouge, Bagneux, Arcueil-Cachan, Villejuif Institut Gustave Roussy and Villejuif Louis Aragon) and eight shafts. The project will take 70 months to complete."

A large project in an urban environment
The T3C section is an outsized project calling for substantial logistics. It will involve two 10 metres diameter earth pressure balanced tunnel boring machines operating simultaneously, removal of 3.2 million tonnes of spoil and placing of more than 470,000 m3 of concrete.
The Villejuif Gustave-Roussy station, whose architecture and dimensions (65 metres diameter, 42 metres depth) epitomize the section, will connect Line 15 South and Line 14 South."

Innovative, ambitious social measures
At peak activity, the project will include nearly 900 people. Extensive steps will be taken to train and induct the long-term unemployed. Support for this work integration programme will be provided by the ViE structure (Vinci insertion Emploi), which Vinci set up in 2011 to help Group subsidiaries carry out such measures. Lastly, an endowment fund, "Chantiers et Territoires Solidaires", has been created to support public interest projects in the vicinity of the worksites. Spie batignolles is strongly committed to the integration of members of underprivileged communities, notably through the Fondation Spie Batignolles."
