Our business

With 13 Multi-expertise regions to provide a local presence close to public-sector and private-sector clients, NGE coordinates 8 core business sectors of construction and public-sector expertise with a single department in ways that benefit customers and projects.

Project financing is cross-disciplinary across all professions and is provided by NGE Concessions, which can invest equity in the projects undertaken by the Group.

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 development and various networks, and 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.

Water cycle

We provide comprehensive solutions in the water cycle sector (pipelines, installation of hydraulic and electromechanical equipment, connections, and related structures). Our teams operate across the entire intervention chain: design, construction, rehabilitation, and maintenance of networks as well as the execution of associated structures through civil engineering and underground works.

We also master trenchless rehabilitation techniques for sewage networks to reduce the impact of construction on public roads.

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.

NGE Engineering

NGE Engineering is NGE’s project engineering department, specializing in execution studies and methods (construction methods, operating procedures, choice of materials, etc.) for design-build projects such as viaducts and stations, which are booming in France and abroad.

Designing an infrastructure is a unique challenge: NGE Engineering objective is to secure design choices adapted to our construction methods at a very early stage. These design choices necessarily support the ecological transition of infrastructures.
