The consortium set to undertake the work includes the Vinci Construction subsidiaries Carrières du Bassin Rhônalpin and Terélian, as well as Eurovia Alpes, SATM, Granulats Vicat, Spie Batignolles Valérian, Spie Batignolles Malet, and GIE GMM 73.

The scope of work includes the industrial processing of approximately 23 million tonnes of excavation materials.

Vinci said a circular approach to the work will be taken, with a focus on the reuse of over 50% of the spoil directly on the site. The project also aims to implement sustainable practices in the handling of excavation materials.

78,000 hours of work ahead

The project includes the establishment of three permanent storage sites, three materials processing stations, eight logistics platforms, 15km of conveyor belts, and a comprehensive train loading facility.

The contract is expected to generate 78,000 hours of work and training for individuals on integration paths throughout the 120-month duration of the works.

Vinci Construction is currently also engaged in digging 23km of twin-tube tunnel on the TELT project, between Saint-Martin-de-la-Porte and Modane.

It is also playing a preparatory role in the construction of the Avrieux shafts near the future safety base at Modane and contributing to the La Maddalena niches on the Italian side of the Alps.
