Rail works. Business activity in connection with the national rail network was spread over numerous maintenance and projects, which included a rail bypass at industrial sites in Donges (western France), putting in new catenaries between Tarbes and Montréjeau (southern France) and renovating the platforms in Gare de Lyon in Paris. Over the year, 252 km of track were fully replaced thanks to the use of two highoutput track renewal trains. Several urban projects were also carried out as part of the Grand Paris Express programme: work on the northern (1.5 km) and southern (14 km) extensions to Line 14 was completed, while work began on the future south western Line 15 (16.5 km) between Boulogne-Billancourt south-west of Paris and VitrysurSeine south of Paris, in synergy with VINCI Energies. Teams also provided modernisation maintenance for private rail networks in the ports of Marseille and Nantes-Saint-Nazaire and a number of major industrial sites.
Hydraulics. Operations related to the water cycle included a large number of maintenance, renovation and diversion projects on drinking water distribution and sewerage networks, as well as the delivery of plants and processes for drinking water production and purification and wastewater treatment, with some 10 projects under way or handed over around France.
Work was also carried out on district and other heating networks in Montpellier, Clichy-la-Garenne (Hauts-de-Seine), Lens (Pas-de-Calais), Pau (Pyrénées-Atlantiques) and several municipalities in the eastern part of France. Fibre-optic network projects also continued, one example being the laying of 3,000 km of fibre to connect 60,000 homes, businesses and government offices in the Meuse administrative department.
Earthworks, maritime and river works. Business activity was spread across a wide variety of infrastructure projects related to roads (northeastern Metz bypass, in Moselle), railways (underground section of Line 18 of the Grand Paris Express, fitout of shafts, highspeed removal of excavated material), flood protection (temporary storage basin on the Bassée site, southeast of Paris, for flood control along the Seine), coastline work (La Cotinière port in Saint-Pierre d’Oléron, Charente-Maritime; Marineff project in Cherbourg, Manche, aimed at protecting marine biodiversity) and nuclear sites (floodwall protecting the Blayais power plant).
Teams also carried out several ecological engineering operations, such as restoring the hydromorphology of the Drevenne river in Isère and the ecological connectivity of the Nonnenhardt ponds in the Bas-Rhin. They also performed specialised maritime and river works (dredging,rock excavation, sheetpile driving, etc.), for instance on a wind farm in the bay of SaintBrieuc (Côtes-d’Armor) and a dam modernisation project at Poses-Amfreville (Eure).
