• 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.
