• 2002 – 2003 : Eiffage Construction Métallique restored the North and West canopies and the awning on the museum’s western forecourt. The steel structures were sent to the Maizières plant (Moselle) where they were renovated according to the regulations in force with new parts shaped and riveted in situ. They were then reassembled on the building, whose western forecourt had already been reinforced by the company.
• 2019 – 2020 : The OPPIC (Opérateur du patrimoine et des projets immobiliers de la culture) chose Eiffage Métal to carry out conservatory renovation on the museum’s eastern tympanum.

Comprising 18,000 glass scales, Les Halles Canopy is a huge plant-shaped envelope, 14,5 m high for a span of 96 m and covering nearly 2.5 hectares.

Eiffage Métal took part in this mammoth project dreamed up by architects Patrick Berger and Jacques Anziutt and built for the City of Paris, with support from engineering consultants Ingérop and Arcora.

The Socri Rénovation Group chose Eiffage Métal to carry out the Framework and Roofing work (Charpente Couverture) on the Polygone shopping centre renovation project in Montpellier. The works amounted to a total of 7 million euros.

 We built a 3,300 m² glass roof made of ETFE (Ethylene tetrafluoroethylene) cushions. This ground-breaking construction method was tested by assembling the blocks away from the steel frame. 5 blocks with total weight of over 225 tonnes were thus launched at night above the shopping centre. Eiffage Métal also built the 1,100 m² of façades surrounding the new glass roof.

At the end of December 2019, Eiffage Métal delivered Le Monde press group’s new headquarters in the 13^th arrondissement of Paris (Zac Paris Rive-Gauche).
​This eight-storey 23,000 m² bridge-building was imagined by integrated design practice Snøhetta. Its steel structure was built in Eiffage Métal’s Lauterbourg plant. The project stands on a concrete slab signed Eiffage Génie Civil, covering the Austerlitz station railway tracks. 

The Galeries Lafayette group has entrusted Eiffage Métal with the “Grand Gestes” lot of the upgrading project for its future store at 52 Champs-Elysées, Paris - formerly the Virgin Megastore. The project involves bold, in-depth building renovation, and Eiffage Métal has built a monumental staircase, entrance tunnel and cantilevered showcases above the central atrium - all made of glass. This architecturally ambitious project requiring high finish and quality standards was designed by Danish architects BIG, Bjarke Ingels Group.

The Centre for National Monuments (Centre des monuments nationaux) has entrusted Eiffage Métal with restoration work on the Hôtel de la Marine in Paris. Our teams took charge of the Glass Roofs and Façades work, including :

• The main 280 m² canopy with metal frame structure and prestressed cables, and  the microperforated stainless steel coverings
• The bronze joinery work and large-scale glazing   
• The second glass canopy with beam clamps and glass stiffeners.

Eiffage Métal produced the metal frame and glass roof for the Saint-Gobain tower cap in Parisian business district La Défense – an operation amounting to nearly 7 M€. Saint-Gobain Tower is a real estate shopping and office complex in a high-rise building comprising 38 storeys above the Esplanade de La Défense and 5 storeys below. Work on the tower cap involved installing a framework and glazed panels 165 m above the ground, and thus posed a very specific technical challenge. The works began in July 2018. The finished project was delivered in Spring 2019.

Eiffage Métal (in consortium) carried out the work on the Luma Foundation Tower in Arles, designed by architect Frank Gehry.

The Luma Foundation façades comprise three main structures :

• a 5,000 m² metal façade supporting 11,000 stainless steel cladding blocks,
• 50 glass boxes protruding from this façade in order to let light into the building
• a glass atrium 56 m in diameter and 18 m high, providing a naturally-ventilated reception area at the foot of the tower.

All the preliminary studies were carried out in 3D. In view of the structure’s geometric complexity, we were dependent on 3D modelling, which enabled us to connect the 2D plans and calculations with the production drawings for the different parts of the structure.

Eiffage Métal took part in renovating the former Paris Docks, the first reinforced concrete building to be listed as a historic monument. Its façades have been upgraded, opening up new cantilevered corridors on the Seine side. The concrete framework was covered with a screen-printed glass sheath known as plug-over, on a tubular steel structure, with a grassed roofscape comprising wood decking and a plant complex. The plug-over is deployed via an arborescent generating method, reflecting the movements of water and the natural environment. This tubular structure in the heart of the capital is a remarkable contemporary benchmark, in terms of its bold architecture and technical prowess.

The Grand Palais, flagship project in Paris' Universal Exhibition of 1900, was upgraded in 2002 with high-precision works of mammoth proportions, revealing the building's bold and modern structure.
Eiffage Metal's teams renovated the metal framework, nave and glass roofs.
Once the building's foundations had been reinforced, the framework components and dome were able to undergo complete restoration. The huge 15,000 m² glass roof was replaced by more resilient laminated glass. In 2004, the structure was awarded a rating in the French Steel Construction Syndicate 's "Upgrading the Finest Steel Structures" category.

This viaduct required 33,000 tonnes of steel. It has a steel box girder structure with an orthotropic deck and is 29 m wide and 1,700 m long, with a maximum span of 210 m. The apron rises to over 150 m above the valley, and was put into place by incremental launching, a process already tried and tested on Millau Viaduct

This 607 m long structure crosses the Saône valley up to 28 m high for its largest pile.

On the Tamarinds Road, Reunion Island, Eiffage Métal built this viaduct’s 288 m x 20 m steel deck across Grande Ravine, 170 m deep.

The bridge spans the River Maine over 136 m, and weighs 720 t. It is supported in the river by two piers built by Eiffage Génie Civil, and will enable the extension of Angers Tram Line B. The Arts et Métiers bridge was designed by architects Lavigne & Chéron.

Eiffage was chosen by French rail network operator RFF in 2011 to finance, design, build and maintain the Brittany - Pays de la Loire high speed line linking Le Mans and Rennes.
All the steel engineering structures along the 182 km of layout were built by Eiffage Métal’s teams.

Faidherbe Bridge in Senegal was built in 1897 to link Saint Louis Island to the African continent, and is now UNESCO World Heritage-listed. The bridge, renovated by Eiffage Métal and Eiffage Sénégal, is 511 m long and comprises 7 steel spans, including one which swings to allow ships to pass. 

Reinforcing the bridge's pillars and reproducing its steel framework identically were a real challenge.

Eiffage's ground-breaking financial and technical choices won us the Millau Viaduct concession in 2001, and enabled us to deliver this emblematic engineering structure in December 2004. The multi-span cable-stayed bridge was designed by British architect Sir Norman Foster and created by French engineer Michel Virlogeux.  It is 343 metres high and 2,460 metres long, comprising 7 concrete piers and a steel deck. 85,000 m3 of concrete and 36,000 tonnes of steel structure were needed to build the viaduct. It took 14 years of preparation and 3 years of construction (2001-2004) to produce the viaduct. All Eiffage's branches were involved,  as were 600 master craftsmen at the height of the project. The bridge was inaugurated on 14 December 2004 by French President Jacques Chirac. In 2006, Eiffage received the International Association for Bridge and Structural Engineering's Outstanding Structure Award. The IABSE praised the viaduct for being "an elegant, slender bridge ...constructed using an innovative launching procedure which advanced the state of practice in bridge construction".

Within the Athletes' Village, the 140 m long and 16 m wide footbridge over L'Île-Saint-Denis calls on the Group's many skills. Under the supervision of Eiffage Génie Civil teams, the consortium chosen by the Seine-Saint-Denis departmental council is made up of Eiffage Métal for the steel structure, Eiffage Fondations for the piles, bars and injections under each of the three supports, ETMF for the sheet piling, Ævia for the prestressing, AER for operations near the worksite, and Eiffage Énergie Systèmes for the lighting. 

Eiffage Métal and its subsidiaries SEH in Germany (leader) and Iemants in Belgium, in a consortium with HOCHTIEF and Max Bögl, have won the contract to build a bridge over the Rhine in Leverkusen, Germany. The future 2 x 3 lane bridge, located on the A1 freeway, will link Leverkusen to Trier. This project aims to double the capacity of the existing bridge, which has become undersized, and is part of the process of improving the quality of bridges in Germany.

The contract, awarded by Die Autobahn GmbH des Bundes (the company responsible for the German motorway network), covers the construction of a 1,068-meter-long structure consisting of a 689-meter-long cable-stayed steel section and a concrete section. The steel elements, totalling nearly 16,000 tonnes of steel, will be manufactured in the Group's European plants, including the Lauterbourg plant in Alsace, and will be delivered via the Rhine.

Commissioned by SNCF Réseau, the Bezons grade separation project is part of the extension of Eole, the Paris RER line E. It is the most emblematic structure for connecting Eole to the existing SNCF tracks. More than one kilometer long, it includes a 96 m long bowstring topped by an arch 23 m above the deck, an asphalt girder pier, a 350 m long low side girder bridge-rail, connecting structures and a 378 m long footbridge, supported by 10 metal brackets anchored by prestressing to the RAPL piles. All the parts were manufactured in our Lauterboug plant. A project in synergy with the Eiffage Génie Civil teams.

Located in Choisy-le-Roi in the Val-de-Marne department, this footbridge for pedestrians and cyclists is attached to the existing Choisy bridge, crossing the Seine and the RER C tracks. The 190 m long structure, weighing 350 t, has 3 supports in the Seine and was installed by crane, with river navigation and rail traffic interrupted. The project was carried out in synergy with Eiffage Génie Civil, ETMF.

With two piers in the sea instead of six, and dedicated routes for pedestrians and cyclists, Eiffage Métal is working with ARBE to help rebuild the Lékiny Bridge in a sustainable manner, which will provide even greater protection for an ecosystem with exceptional marine biodiversity.
The mixed structure with double metal caissons will cross one of the most beautiful lagoons in the world, the Ouvéa lagoon in New Caledonia, which was classified as a UNESCO World Heritage Site in 2008. Thank you to the Loyalty Islands Province / Gemoce for their confidence.
