As for the circular economy, VINCI Construction is stepping up recycling of construction materials (Granulat+). It also offers cost effective digital solutions, such as Waste Marketplace and R.Used, that can help to optimise the management of worksite waste and the reuse of materials and equipment, or La Ressourcerie du BTP, a platform that lists materials available for reuse that have been collected from deconstruction sites. Similarly, in its roadworks operations, VINCI Construction has been rolling out advanced techniques for insitu recycling of road surfaces during road repair work.
With regard to preserving natural environments, VINCI Construction brings together a wide range of expertise in ecological engineering, mainly under the Equo Vivo brand, and works closely with nature conservation organisations and institutions in order to protect biodiversity around its quarries and on its worksites.2022 marked the 10th year of VINCI Construction’s national partnership with PatriNat, which brings together France’s Natural History Museum, the National Centre for Scientific Research and the French Biodiversity Agency.
In France, as part of the Grand Paris Express, the largest urban mobility infrastructure programme in Europe: completion of the civil engineering works package on Line 15 South (8 km of tunnels and five stations) between Issy les Moulineaux and Villejuif, continuation of building work on the Noisy Champs station on the same line, civil engineering work on Line 14 South between Olympiades and Paris Orly airport (4.6 km of tunnels, Kremlin Bicêtre Hôpital station, five shafts) and work on the underground and overhead sections of Line 18 (11.8 km of tunnels, 13 ancillary structures, 6.7 km of viaducts and three stations along the overhead section). The business line has also launched works package 2 on the future Euralpin Lyon–Turin rail tunnel (23 km of twin tube tunnel in Savoie), following on from the current contract for the construction of four 500metredeep ventilation shafts.
In the United Kingdom: the consortium encompassing VINCI Construction and Balfour Beatty is working on the main civil engineering works packages of the High Speed 2 line (see Close-up, page 103).
In Denmark: the Fehmarnbelt Fixed Link, which will be the world’s longest immersed tunnel (18 km long, 89 prefabricated concrete sections, each 200 metres long) and connect the Danish and German coasts by road and rail.
In Egypt: extension of Line 3 (18 km of new track) of the Cairo metro, a project for which VINCI Construction has been providing both civil engineering and railway works for over four decades.
In the United States: extension and refurbishment of the I64 interstate highway between Hampton and Norfolk, Virginia, including construction of two tunnels, each 2.4 km long, between two artificial islands, and widening of 14.5 km of existing roads.
In Canada: the Confederation Line in Ottawa (27.5 km of light rail infrastructure, 20 engineering structures and 16 stations, plus widening of 12 km of motorway); the West Calgary Ring Road in Alberta (a 5 km section including four interchanges and seven overpasses); renovation of the Louis Hippolyte La Fontaine tunnel in Montreal. Additionally, work has begun on a major portion of the Ontario Line subway in Toronto (a 6 km twin tube tunnel, with seven new stations) as part of a contract won in November 2022 with joint venture partner Ferrovial.
In New Zealand: Auckland’s City Rail Link project, the country’s largest ever infrastructure project, involving a 3.5 km extension including 3.2 km of tunnels and three new stations.
In Colombia: the Bogotá–Girardot motorway, which VINCI Construction is widening in part and refurbishing in its entirety for VINCI Highways.
Activity was also sustained in water infrastructure, with major climate resilience and renewable energy production projects: in the United Kingdom, the Thames Tideway (East works package), a vast programme to extend the system that transfers and stores London’s wastewater and stormwater in an effort to prevent polluting the Thames; in Morocco, the Abdelmoumen 350 MW pumped storage hydroelectric plant; in Senegal, the Sambangalou dam on the Gambia river, which will generate energy, improve irrigation and supply drinking water to neighbouring regions; in Cambodia, the Bakheng water treatment plant, which will eventually supply drinking water to 1.5 million people in the northeast of the capital, Phnom Penh; in Canada, the new contract for the construction of a series of structures designed to protect people living in the wider Calgary region by diverting and temporarily storing water from the Elbow river during peak volume events.
