The Société des Grands Projets has awarded the first design-build contract for the Grand Paris Express to the IntenCités15 consortium, led by VINCI Construction Grands Projets. It concerns the southern section of line 15 West, which will connect Pont de Sèvres station to La Défense.
The largest infrastructure and urban development project currently underway in Europe, the Grand Paris Express will double the length of the metro network with 200 km of new lines, including the creation of 4 new lines around Paris (lines 15, 16, 17 and 18), 90% of which will run underground, the extension of 2 lines (lines 11 and 14), 68 new stations and the development of new districts around these future urban-transport hubs. 3 million passengers will use these new lines every day.
The deployment and funding for this major urban-development project is being steered by the Société des grands projets (SGP), a public establishment created by the French government.
Since 2017, the Major Projects Division has leveraged its expertise to contribute to the construction of 14 stations, 38.6 km of tunnels, and 6.7 km of viaducts on lines 18, 15 South, 15 West South, and 14 South.
The Ontario Line will be a 15.6-kilometre subway line that will make it faster and easier to travel within Toronto and beyond. The line will bring 15 new stations to the city and will run from Exhibition Place, through the heart of downtown, all the way up to the Eglinton Crosstown LRT (Line 5) in Flemingdon Park. Construction is now underway. VINCI Construction Grands Projets and Ferrovial Construction have joined together to form the Ontario Transit Group to deliver the Ontario Line Southern Civils, Stations and Tunnel contract.
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.
