VINCI Construction, through a joint venture led by Dodin Campenon Bernard, has completed tunnelling Line B, the second automated metro line in Rennes, for regional authority Rennes Metropole and transport authority Semtcar.
The joint venture includes GTM Ouest and Botte Fondations, both subsidiaries of VINCI Construction France, and Spie Batignolles TPCI, Spie Fondations and Legendre Genie Civil.
Line B will run between the south-west and north-east of the urban area and serve 15 stations by 2020.
After 38 months of operation, tunnel-boring machine Elaine arrived at its exit shaft.
At the end of this phase, Elaine completes 8.5km underground, passing nine stations and four ventilation shafts.
The tunnel-boring machine, which measures 82m long and has a diameter of 9m, has installed 29,806 arch liners.
The project is scheduled for completion during the summer of 2018.
Line B of the Rennes metro is designed to support the urban area’s growth. The Rennes network (STAR) had recorded 76.8 million trips in 2014 and with the creation of Line B, traffic is expected to reach 120 million trips in 2020.
VINCI companies are currently involved in several projects all over the world, including the metro systems in Cairo, Egypt; Doha, Qatar; and Lines 14 South and 15 South of the Grand Paris Express rapid transit programme.
In February 2018, a consortium led by VINCI Construction (Dodin Campenon Bernard, lead company; VINCI Construction France; VINCI Construction Grands Projets and Botte Fondations), along with Spie Batignolles (Spie Batignolles Genie Civil and Spie Batignolles Fondations), was awarded a major contract as part of the Grand Paris Express programme.
The RATP1 has selected the consortium to execute works package GC02 of the future Line 14 South between Olympiades (in the 13th arrondissement of Paris) and Orly Airport.
The €400m contract involves the use of an earth pressure balance tunnel-boring machine to excavate a 4.6km tunnel between Maison Blanche Paris XIII future station and the TBM starting shaft at Jean Prouve, as well as construction of the new Kremlin Bicetre Hopital station and five ventilation and emergency shafts.
