Our business
With 13 Multi-expertise regions to provide a local presence close to public-sector and private-sector clients, NGE coordinates 7 core business sectors of construction and public-sector expertise with a single department in ways that benefit customers and projects.
A Concessions core business offers complementary expertise in project funding, makes equity investments and develops the Group’s concession assets. It also includes a team dedicated to property development.
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.
In subsidiary companies and regional bases throughout France, our teams work on local and large-scale projects on behalf of private- and public-sector customers.
Our subsidiaries Urban infrastructures & earthworks
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, transfer and treatment of wastewater, the replacement and interconnection of water abstraction pipelines and associated hydraulic structures, drinking water treatment, and the installation and fit-out of dry networks, especially those for electricity supply.
As part of delivering the French Superfast Broadband Plan, we created a subsidiary company called NGE INFRANET to focus exclusively on the rollout of optical fibre connections to provide high-speed Internet access to those areas previously not connected.

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 using traditional construction methods and tunnel boring machines, on large-scale excavations, and in the repair and safety upgrading of road, rail and water systems engineered structures.
This work is carried out by our subsidiary NGE Génie Civil, which has a presence in all our multi-expertise regions and within the Major Projects department.

Road building & road equipment
We carry out every type of surfacing work required for the construction of roads, motorways, airports, urban road networks, etc. Our subsidiary company AGILIS also gives us an involvement in the supply and installation of road equipment by offering alternatives such as concrete road surfaces and a comprehensive range of equipment, including restraint systems, acoustic screens, road markings and surface cleaning.
Our binder plants and fixed and mobile asphalt production plants make us self-sufficient throughout France. We are also able to rely on our own quarries, which again we operate completely independently.

Geotechnical solutions
Controlling soil-related risks is an area of expertise inseparable from the process of constructing engineered structures. Our subsidiaries offer the full range of geotechnical engineering and site safety techniques applicable to every type of public contracting and construction project.
They are involved in various complex and highly technical operations in soil improvement, deep foundations, reinforcement, supports, marine and underwater river works, difficult access works, etc. Thanks to exclusive patents and processes (AD/OC® nailed wall ELITE® products), they implement innovative solutions against 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.
Electrification and civil engineering signalling works are carried out by TSO Caténaires.
Other specialist services, such as topographic studies, rail industry software development, the rebuilding of mainline and shunting locomotives, and rail safety, enable us to offer a comprehensive range of services.
