Our business

With 13 Multi-expertise regions to provide a local presence close to public-sector and private-sector customers, 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.

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.
