Our integrated solutions

Our teams lead the consortium appointed by BP to build the Grand Tortue/Ahmeyim gas terminal: offshore docking infrastructure protected by a breakwater dyke. The 1.2 km-long breakwater dyke comprises 21 concrete caissons each weighing 16,500 tonnes and manufactured by Eiffage in Dakar (Senegal). It will be installed at -33 m, 10 km off the coast. At the same time, the 2.5 million tonnes of quarry materials required for the underwater dyke foundations supporting the concrete caissons are being produced by Eiffage in Mauritania in a quarry opened specifically for the project.

The consortium comprising Eiffage’s companies (leader) and APRR is concession operator for the A79 motorway (Atlantic Centre-Europe Route) by ministerial decree published in the Journal Officiel on 15 March 2020. The 48-year concession contract covers the financing, design, development, extension, upgrading to motorway standards, operation, upkeep and maintenance of an 89-kilomentre stretch of the current trunk road (RN) 79 between Sazeret (Allier) and Digoin (Saône-et-Loire) which will become the A79.

The design works, extension to 2x2 lanes and upgrading to motorway standards are to be carried out by Eiffage Génie Civil’s teams. They will also mobilize Eiffage Route, Eiffage Métal and Eiffage Énergie Systèmes. Engineering consultancy services on the project will be provided by Egis.

The future High Speed 2 (HS2) high speed rail link built as part of a joint venture involving Eiffage, Kier, Ferrovial Construction and BAM Nuttall will serve the north of the United Kingdom.

The project involves building lots C2 and C3 pf the future high-speed line. This stretch includes 15 viaducts, 5 km of cut and cover, 22 km of road realignment, 67 crossing structures and 30 million cubic metres of earthworks. The contract totals 2,269 billion pounds sterling (around 2.6 billion euros) including the initial design and development phase already completed.

This design and build project involving Eiffage Génie Civil and Eiffage Énergie Systèmes is located on the Bandama River between Abidjan and Yamoussoukro. It includes building a riprap and concrete composite dam, flood spillway, plant to house the turbines, discharge channel, switchyard, line connecting the power station to the network, temporary facilities and access roads.

Eiffage is taking part in developing the Paris region’s future public transport network via the Grand Paris project.

- Line 15 South - Lot T2B (in consortium) includes a 7.2 km tunnel and 3 stations : Saint-Maur - Créteil, Champigny Centre and Bry-Villiers-Champigny.

- Line 16 - Lot 1 includes 19 km of tunnel and 5 stations (Saint-Denis Pleyel, Stade de France, La Courneuve Six-Routes, Le Bourget RER and Le Blanc-Mesnil), 21 ancillary structures, track-laying and catenaries.

- Line 14 South (in consortium) includes a 4 km tunnel and 3 stations (Chevilly Trois-Communes, MIN Porte de Thiais and Pont de Rungis).

- Eole extension –RER Line E includes a 6,1 km tunnel, a station under the Porte Maillot, Bezons flyover (a kilometre-long engineering structure) and rail works (tracks and catenaries).

Eiffage Génie Civil in consortium is handling civil engineering work on the Ivry-Paris XIII waste recovery centre. The facility’s global design-build-operation contract was awarded by the Syctom (syndicate in charge of waste treatment and recovery for 84 municipalities in the Paris region) to the P13 consortium led by Suez Environment subsidiary Sita, with whom Eiffage Génie Civil is co-contractor. The project aims to reduce the volume of waste incinerated on the site and improve energy efficiency compared to the current facility. It involves creating a new energy recovery unit with an annual 350,000 tonne capacity and digging an underground link between the plant and Marcel-Boyer Quay in Ivry-sur-Seine, in order to limit road transport in favour of river navigation.

Eiffage Génie Civil is taking part in modernizing Seine Aval water treatment plant (78). This 800-hectare facility treats 70% of Paris urban area’s waste water, totalling 1.5 million m3 per year.

France’s National Centre for Space Study (CNES) has chosen Eclair6, the consortium led by Eiffage Génie Civil, to carry out infrastructure work for the Ariane 6 launch site ELA4 in the Space Centre in French Guiana. The lot comprises all the ELA4 structures, including the launch pad and its two flues, mobile gantry (6,000 tonnes and 90 metres high) and the Vehicle Assembly Building. These works involve the deployment of 60,000 m³ of concrete, 7,000 tonnes of steel reinforcement, 400,000 m³ of earthworks and 7,500 tonnes of metal framework.

This HSL known as “BPL” was constructed as part of a 25-year public-private partnership contract signed on 28 July 2011 between RFF and Eiffage’s dedicated subsidiary Eiffage Rail Express (ERE). This project to extend the existing HSL between Paris and Connerré (20 km east of Le Mans) mainly involved building 182 km of new line to significantly improve access to western France, bringing Rennes to under an hour and a half from Paris. Most of the layout, including earthworks, sanitation, engineering structures and rail track, was constructed by Eiffage’s teams, all trades combined.

The Avenir motorway is the first PPP in Sub-Saharan Africa, the first link of the Dakar-Diamniadio motorway and the first toll motorway in West Africa. Via this partnership, the Senegalese government entrusted Eiffage with the financing, design, construction, operation and maintenance of a first stretch between Dakar and Diamniadio. Eiffage Génie Civil took part in building this 25.5 km infrastructure enabling a significant reduction in travel time from 2 hours to 30 minutes.

This 30-year contract was completed by a 25-year contract to extend the motorway to Blaise Diagne International Airport, covering financing, design, construction and operation. With this 14 km stretch commissioned in October 2016, the Avenir motorway now links the centre of Dakar to the new airport and Saly-Mbour tourist area.

Decathlon Arena Stadium Pierre-Mauroy in Villeneuve-d’Ascq, originally known as the Grand Stade Lille Métropole (GSLM), is a unique urban engineering structure. The building has a capacity of 50,000 in stadium mode, and can be transformed into a 25,000-seat showcase venue in just 24 hours, by means of an exclusive, ground-breaking system whereby the northern half  of the pitch is designed to lift up and slide over the southern half. The mobile roof can open and shut in only 30 minutes. A giant screen on the stadium's outside envelope facing the esplanade enables live transmission of matches and competitions.

This project consists of the design-build of the E18 motorway section that will connect the cities of Langangen and Rugtvedt. The contract also includes a total of 900 meters for the Blafjell tunnels to be excavated and equipped, as well as a total of 3.3 kilometers for the Kjørholt and Bamble tunnels, which have already been excavated but remain to be equipped.  

Delivery of this emblematic contract, which aims to achieve Ceequal "Excellent" level certification, is scheduled for the summer of 2025.

The 44.4 km Perpignan-Figueras high-speed line (HSL) crosses the French-Spanish border between France and Spain via the 8.3-kilometre Perthus tunnel under the Pyrenees. This ground-breaking new line can accommodate both high-speed trains (TGV) travelling at 350 km/h and freight convoys at 120 km/h – a “mix” that is a first for this type of infrastructure.

This 155 km infrastructure linking Viseu and Chaves involved over 6 years’ work. During this time, 26 million cubic metres of earth were excavated and 130 engineering structures built, including Corgo and Vila Pouca de Aguiar viaducts (of which the second is the longest on the line).

Located on Colombia's Atlantic coast, the Puerto Antioquia project is considered by the Colombian government as a priority project of national interest. It is strategically positioned on a major international container transport axis, close to Medellin, one of the country's main economic zones.
 
The contract covers the design and construction of a complete port infrastructure including an offshore platform - for the simultaneous berthing of 5 container ships - linked, by a 3.5 kilometer offshore viaduct and a 320 meter bridge, to a 35 hectare land terminal fully equipped with its operating buildings and warehouses.
