At Eiffage Génie Civil we have proven expertise in constructing and laying high-pressure pipelines for gas and hydrocarbon transport. Whether the work involved is a new project or maintenance on structures in operation, our customers can count on a high standard of achievement from Eiffage Génie Civil’s French and international teams.
Transporting fluids in high-pressure pipelines.
Eiffage Génie Civil installs pipelines to transport natural gas, hydrocarbons (raw and refined products and biofuels) and high-pressure fluids (compressed air, ethylene, nitrogen, oxygen, helium and hydrogen). Our teams specialize in complex earth projects, contributing their expertise to small, medium and large-scale sites, from the smallest diameter up to 36 inch-diameters (DN900). They are able to offer high-speed laying techniques over long distances, and also work on structures in operation :
- pipeline network development and diversion
- inerting and removal
- special points, interconnection
- pipeline fault monitoring
- covering repairs
- work on concentrated structures (compression stations)
- work in confined spaces (pipe repairs and/or replacement in utility tunnels).
Integrated engineering : expertise at all stages of your project
Our teams take charge of all phases of the works, guaranteeing overall project control. Our specialists follow an integrated detail engineering schedule, from the opening of the tracks to the final site restoration work, in conventional trench layouts and at special points : cladding, shoring, welding, non-destructive testing, coating, trenches, pipe-laying in trenches, connections, backfill and site restoration, hydraulic tests and block-valve stations.

Certification : a guarantee
Eiffage Génie Civil is certified OHSAS 18001, ISO 9001 and 14001, as part of our commitment to the ongoing improvement of our HSE performance and safety initiatives.
Eco-responsible practices and materials
Sustainable development and the environment are central to the choices and actions which drive our company.
Eiffage Génie Civil favours in-situ materials recycling techniques, waste treatment and site restoration, so as to limit the environmental impact of our operations.
We control the preliminary studies, hydrostatic testing and regulatory monitoring operations before the structure is commissioned. Our cutting-edge and specific materials are compliant with the most recent safety and environmental standards.
We make a point of restoring the sites we work on to their original state, in compliance with environmental standards on each of our operations.
The Pipelines teams in the Jura
Eiffage Génie Civil was chosen by French Jura pipelines company SFPLJ (Société Française de Pipeline du Jura) to replace 11.4 km of pipelines – 4 stretches of DN400 pipeline – in Valdahon (25) in the direction of Switzerland.
Risk management at all stages of the works
Compliance with safety requirements is central to our DNA, driving our teams at all times. In both the study and works phases, they integrate into the works management all the factors guaranteeing safety for project stakeholders, and the integrity of existing facilities. By acting upstream of the project and on early warning signals, our staff work to eliminate risks beyond mere compliance with the standards in force.
