Two major contracts awarded for future Grand Paris Express worth £586m

Two contracts worth a total of €668m (£586m) have been awarded this week for construction work on the future Grand Paris Express transport network.

A team of Bouygues Travaux Publics with Soletanche Bachy France, Soletanche Bachy Tunnels, Bessac and Sade has been chosen for a €513m contract involving 4km of tunnels and the Pont-de-Sèvres and Issy RER stations.

A joint venture of Vinci Construction and Spie Batignolles has won a €156m civil engineering contract for Noisy-Champs station. The project also includes other carriage sidings and a road bridge over regional express tracks. The station work involves construction of the frame, glazed facades and various pedestrian walkways including stairs and footbridges. Work will get under way in the late summer. The building’s distinctive architecture by Jean-Marie Duthilleul includes a helical dome. The dome and the walkways will require 1,650t of steel. To help protect the environment, a stormwater basin will be built at the site. All recovered water will be recycled to supply the concrete and mud plants for the site.
