The Fréjus railway tunnel, opened in 1871, rises to an altitude of 1,300 metres and has a gradient of up to 3%. This means that the trains running through it have to be equipped with three locomotives, resulting in a 40% increase in energy costs.
The new tunnel, currently under construction, will transform the existing mountain line into a line with a lowland profile, making rail transport more competitive, with energy savings and higher speeds.
The contract concerns the civil engineering aspects for a section of the future line 15 south of the Grand Paris Express connecting Fort d’Issy-Vanves-Clamart to Villejuif Louis Aragon and includes the creation of 8 km of tunnels as well as the construction of 8 shafts and 5 new stations.
Dug using traditional tunnelling techniques, this project required significant human and logistical resources due to the complexity of the construction site’s terrain. In February 2017, the construction project for this T3C section was awarded to the CAP group headed by VINCI Construction.
This project aims to build a 190,000 m³ liquefied natural gas (LNG) reservoir in the United Kingdom.
Located on the Isle of Grain – England’s east coast, 60 km from London – this project is part of the program to expand the capacity of Europe’s largest LNG terminal. This “full integrity” tank has an internal tank made of 9% nickel steel and an external enclosure made of prestressed concrete poured in place using slip forms.
The project involves the design/construction of a drinking water supply system with a capacity of 15,000 m3 per day and includes the construction of a drinking water treatment plant and the installation of a 6.5km cast-iron distribution pipeline with a diameter of 700 mm.
The project consists of the construction of a 65 km long third lane on the existing motorway, and the construction of three bi-directional tunnels with a total length of 2 km, in order to upgrade and widen the infrastructure on which more than 15 million vehicles travel each year.
The contract also includes the operation of the 141 km of this motorway between Bogotá and Girardot, in the Cundinamarca and Tolima regions.
This design-build contract covers the construction of a drinking water treatment plant and transfer pipelines. The supply system will ultimately provide drinking water to more than 1.5 million people living in the north-east of Phnom Penh.
The construction of this dam, 91 meters high and with a capacity of 128 MW, will allow the production of renewable energy, the development of irrigation of agricultural land as well as the supply of drinking water to surrounding communities. The works will start in the first half of 2021 and will last 48 months. At peak activity, the site will employ 1,000 people recruited and trained locally.
Step 1 of a Design and build contract of a new passenger terminal with a surface area of approximately 40,000 m2 offering 8 new boarding bridges and airport services such as luggage sorting.
La Société du Grand Paris ha adjudicado al consorcio liderado por VINCI Construction Grands Projets el contrato de realización del tramo aéreo de la línea 18 del Grand Paris Express, de 7,4 km de longitud, que unirá Massy-Palaiseau con la futura estación CEA Saint-Aubin. La puesta en servicio está prevista para el 2026.
For the completion of the Lyon-Turin line, the work package awarded by the public client Tunnel Euralpin Lyon Turin (TELT) covers preparatory work on the future safety site at Modane, which is located at the centre of the base tunnel linking the international railway stations of Saint-Jean-de-Maurienne (France) and Susa (Italy) over a distance of 57 km.
Package 5A includes the construction of 4 ventilation shafts, each 500 metres long, at the foot of which 7 large caverns and 3 kms of galleries will be built, in the municipality of Avrieux; it represents a key stage in the project. Starting at the end of 2020 using an innovative technique known as raise-boring, the project took3 years and involved up to 450 people.
