New metro Lines 2 and 3 in Athens criss-cross the city from north to south and east to west. This turnkey design-build project included two tunnels, 9.2 and 8.4 kilometres long, respectively, and no fewer than 21 stations. This infrastructure, which is used by 600,000 passengers on a daily basis, has reduced car traffic in the city centre and cut the pollution that is harming the Greek capital’s historic centre by 8%. Today, the Athens metro is among the most modern in all of Europe.
Santiago Airport occupies a strategic position in South America (the continent sixth-largest airport) and especially in Chile where it is a hub for international connections.
In conjunction with our partners, we build five new terminals, which will cover a total surface area of 250,000 m², designed to double the airport’s current capacity from 15 to 30 million passengers.
The contract also calls for upgrades to part of the existing 30,000-m² terminal, two four-level car parks with a surface area of 93,000 m² and 800,000 m² of surface car-parks and airports roads.
The new coastal road project is designed to provide a safer road connection between Reunion Island’s two main urban centres (Saint-Denis, the largest city, and La Possession).
This new road infrastructure is 12.5 kilometres long, and its construction was divided into several work packages. One of the two main work packages was the full-service construction of a viaduct between Saint-Denis and La Grande Chaloupe.
The contract awarded to the VINCI Construction Grands Projets consortium called for the design and construction of this 5.4-kilometre viaduct, to be built in the sea along the coastline.
The Yamal peninsual is located 400 kilometres north of the Arctic Circle in western Siberia in the Gulf of Ob. It is in this region, which is iced over nine months a year, that the Yamal LNG project is being carried out. Our mandate is to design, supply equipment, materials, and provisions, and build and equip four double-walled cryogenic tanks, each with a capacity of 160,000 cubic metres, to store liquefied natural gas (LNG).
An innovative approach allowed us to reduce in half the number of foundation piles needed for this atypical ground, namely, permafrost. In less than a year and a half, the contract was signed, the team was mobilised, foundations were designed and built, and the civil engineering for the tank chambers was completed.
How can the Chernobyl site be cleaned up in complete safety? Our team of engineers devised a prototype arch to confine, sort, store, and stockpile radioactive waste materials – while ensuring maximum protection for workers on site. The arch-shaped confinement structure designed to enable the dismantling of the old sarcophagus and the remains of the damaged reactor consists of a metal frame weighing 36,000 tonnes (fully equipped), measuring 105 metres in height and 150 metres in length, with a span of 257 metres. The structure is large enough to cover the Stade de France or the Statue of Liberty or the ground around the Eiffel Tower. The arch is as tall as a 30-storey building.
VINCI Construction Grands Projets was mandated to build this cable-stayed, dual 2-lane, concrete roadway bridge that will be 1,050 metres long, with a main span of 530 metres, pylons 212.5 metres high, and a vertical clearance of 75 metres. The structure is located 3 kilometres north of the Gatun locks near the city of Colón. The bridge is designed to allow the passage of the huge Post-Panamax container ships as part of the Canal’s post-expansion operations. It will also allow vehicles to cross the Panama Canal on the Atlantic side regardless of whether the locks are in operation or not.
On May 30, 2016 in Copenhagen, the consortium made up of VINCI Construction Grands Projets, Soletanche Bachy International, BAM Infra / Int., CFE, Wayss & Freytag, MaxBo?gl, and PerAarsleffA/S signed design-build contracts with the government of Denmark to develop the world’s longest immersed road and rail tunnel, which will link Denmark and Germany. The project consists of three work packages: the immersed tunnel; the production plant for the tunnel’s prefabricated segments; and access ramps and bridges.
This colossal, 17.6-km structure will provide separate lanes for road and rail traffic. It will be the longest structure of its kind in the world.
The project’s objective is to connect the State of Kentucky to Indiana by road, which requires the construction (in this case, as part of a design-build mandate) of a 762-metre cable-stayed bridge over the Ohio River, development (again, design-build) of a 512-metre twin-tube tunnel to access the bridge from the Kentucky side, construction of 19 engineering structures, and upgrades to the roadway network and related infrastructure in order to make this route – a 12-km dual 2-lane highway – as modern and safe as possible. The Ohio River Bridges project is the first public-private partnership (PPP) contract signed by VINCI in the United States.
VINCI Construction Grands Projets was mandated to design and build an immersed tunnel (1 x 2 lanes and 2 x 3 lanes, 715 m long) and renovate and rebuild an existing immersed tunnel.
In addition to the construction of an immersed tunnel (2nd Coentunnel) and renovation of the 1st Coentunnel, the project calls for: 2 new engineering structures, 12 structured to be widened, 13 structures to renovate, 14 kilometres of roadway to build, and noise-attenuation and anti-pollution barriers to install.
This project is part of an initiative to double the number of lanes on motorway A10 (northwest section of the ring road) and the access onto motorway A8 northwest of Amsterdam.
As part of the GATE (Gas Access To Europe) project conducted in consortium with Italian and Spanish firms Techint and Sener, VINCI Construction Grands Projets and Entrepose Contracting designed and built three liquefied natural gas (LNG) storage tanks, each with a capacity of 180,000 cubic metres. These structures are part of a building program for a regasification terminal with a capacity of 8,000 million cubic metres a year. The project, which was carried out in an Oil & Gas environment that called on the Group’s full experience and expertise, confirms the outstanding synergies that exist within VINCI’s diverse business lines and skilled trades.
