What we do

Urban infrastructures & earthworks

We have amassed a great deal of experience in urban infrastructures and earthworks, since these are the foundations on which the success of the Group has been built. Our many major motorway and LGV High-Speed Rail Line construction projects have established us as one of the leading specialists in these fields.

Our international, subsidiary company and regional teams work on local and major projects on behalf of private- and public-sector customers.

PIPELINES & OTHER UNDERGROUND NETWORKS

We provide a comprehensive service for water supply and wastewater drainage networks. We are expert in all the techniques involved in the collection, piping and treatment of wastewater, the replacement and interconnection of water mains and the associated hydraulic works, drinking water treatment, and the installation and fit-out of dry networks, especially those for electricity supply.

CIVIL ENGINEERING

Transport infrastructures (road and rail engineered structures), industrial infrastructures (wastewater treatment plants, water reservoirs, hydropower plants, etc.) and functional infrastructures (museums, arts centres, etc.) together represent the main strands of our civil engineering core business.

Our expertise is also at work underground with tunnel construction and large-scale excavations, as well as in the repair and safety upgrading of road, rail and water systems engineered structures.

ROAD BUILDING & ROAD EQUIPMENT

We carry out every type of surfacing work required for the construction of roads, motorways, airports, urban road networks, etc. We also supply and install road equipment, offering alternatives such as concrete road surfaces and a comprehensive range of equipment, including restraint systems, acoustic screens, road markings and surface cleaning.

GEOTECHNICAL SOLUTIONS

Controlling soil-related risks is an area of expertise inseparable from the process of constructing engineered structures. We develop and provide the full range of geotechnical engineering and site safety techniques applicable to every type of public contracting and construction project. We are involved in a broad range of complex and highly technical operations in soil improvement, deep foundations, reinforcement, supports, marine and underwater river works, difficult access works, etc. Our exclusive patents and processes (AD/OC® nailed wall ELITE® products) give us the ability to implement innovative solutions to counter natural risks.

RAIL INFRASTRUCTURES

Our specialists are involved in the construction, upgrading and maintenance of rail track and catenaries. The work of this core business serves rail networks, high-speed rail line projects and urban networks, such as metro and tramway systems.

We also provide electrification and civil engineering works for signalling systems.

Other specialist services, such as topographic studies, rail industry software development, the rebuilding of mainline and shunting locomotives, and track safety, enable us to offer a comprehensive range of services.

PROJECT FUNDING

NGE CONCESSIONS is the core business responsible for developing and arranging the Group’s funded projects. It provides support for customer projects and is involved whenever the Group’s core sectors of expertise are approached to deliver local and major projects.

NGE CONCESSIONS makes equity investments in its projects, but also maintains a presence in operating companies, thereby facilitating the long-term alignment of interests between funding provider, designer, builder and operator/maintenance provider.
