Implenia is awarded the contract for the third section of the Grand Paris Express with AVENIR partners
Dietlikon, 28 January 2019 – Société du Grand Paris (SGP) has commissioned the joint venture AVENIR, consisting of Implenia (business management and technical mandate), DEMATHIEU BARD CONSTRUCTION (overall responsibility), Royal BAM Group and Pizzarotti (each with a 25 percent stake) to build Section 1 of the new metro line 17 North of the Grand Paris Express. The order volume amounts to approximately EUR 440 million (CHF 500 million).
Section 1 consists of tunnel which is about six kilometres in length, two new underground metro stations (Le Bourget Aéroport and Triangle de Gonesse), six annex structures (mainly ventilation shafts and security access shafts), the TBM interim starting shaft in Bonneuil-en-France and a 750-metre preliminary cut in Gonesse. The new line will be connected to the urban transport network and partially built new.
The tunnel will be dug out using a tunnel boring machine (TBM) and have a diameter of some 8.7 metres. The geological conditions are well-known based on various drillings. Implenia is proud to be able to make its experience and expertise available in the area of urban underground construction and dedicate its resources to implementing this complex project. Special foundations work will start in May 2019.

In all these projects Implenia is collaborating with French partners.
