Vinci consortium wins $1.69bn contract for Lyon–Turin railway line


A consortium led by Vinci Construction Grands Projets has secured a $1.69bn (€1.43bn) contract for excavating 46km of tunnels for the Lyon–Turin railway line.

The consortium also includes Dodin Campenon Bernard and Vinci Construction France, both subsidiaries of Vinci Construction and Webuild.

Webuild and French group Vinci each hold a 50% stake in the joint venture which secured the contract.

The scope of work under the contract involves construction of a 23km section of twin-tube tunnel between Saint-Martin-la-Porte and Modane, in Savoie, France.

Awarded by Tunnel Euralpin Lyon Turin (TELT), the contract covering works package 2, includes Work Sites 6 (La Praz) and 7 (Saint-Martin-de-la-Porte).

Work on the project also involves digging 25km of tunnel using three tunnel boring machines and 21km of tunnel using conventional methods. This will create 71 safety tunnels as well as several galleries.

Vinci stated that the project will last for more than five years and is expected create approximately 1,650 jobs.

The complete TELT project will extend for 65km between Susa in Piedmont, Italy and Saint-Jean-de-Maurienne in Savoy, France.

Of the total 65km length, about 57.5km of the tunnel will be underground, and around 10km have already been excavated.

The latest contract is part of construction of a 57.5km tunnel which will connect Saint-Jean-de-Maurienne in France and Susa in Italy.

This is the second contract for the project that has been awarded to Webuild. The company and its JV partners secured a contract for Lot 5A last year.

The contract involved preparatory works for a safety site at Modane as well as four ventilation shafts for the future base tunnel.

VINCI said that the Lyon–Turin railway line is part of a programme to expand trade in Europe upgrade passenger travel.

By 2030, this line will replace one million heavy vehicles on Alpine roads and is expected to contribute to the reduction of three million tonnes of carbon emissions per year.
