The cornerstone of railway projects
We optimise the management of excavated earth, adapt to geological constraints and respect the natural environment: each earthworks operation paves the way for the overall success of the project.

Technical excellence for complex projects
The robust and durable structures we design – viaducts, cut-and-cover sections, tunnels, etc. – ensure the continuity of the route. Each structure showcases our technical expertise and our commitment to safe and sustainable mobility.

Nature in its rightful place
Every project is designed to minimise environmental impact and restore nature along railway lines. This commitment includes reusing excavated materials, creating ecological corridors and re-landscaping.

High-speed technologies
We use BIM (Building Information Modelling), real-time monitoring and industrialised construction methods to improve quality, lead times and safety. Innovation is at the heart of every stage of our railway projects.

Safe and resilient infrastructure for future generations
Growing demand for low-carbon mobility is speeding up the transformation of rail networks. As a leading player in this transition, we are using our expertise to design and build high-performance, safe and environmentally friendly lines.
Our teams are involved throughout the entire project lifecycle, from large-scale earthworks to civil engineering for stations, tunnels and engineering structures. Our most iconic projects include:
- the HS2 high-speed line (United Kingdom)
- the Nîmes-Montpellier bypass (France)
- the Rhine-Rhône high-speed line (France)
- the Gautrain rapid transit line (South Africa)"
Smooth, connected mobility
Situated above or below ground, railway stations are turning into true intermodal hubs. Through a combination of precision engineering, safety and passenger comfort, we ensure that journeys are smooth and connected.
Our projects
Gautrain Rapid Rail System
Design, construction and operation of an 80-km rapid rail line, delivered in time for the 2010 FIFA World Cup and recognised for its environmental performance.
High Speed 2 (HS2)
Between London and Birmingham, as part of the Align consortium, we built 21.6 km of infrastructure, including a 16 km twin-tube tunnel and a 3.4 km viaduct.
Nîmes-Montpellier rail bypass
Construction of 80 km of new track, including 60 km of high-speed track and 183 bridges. A public-private partnership.
Rhine-Rhône high-speed rail
A key infrastructure project, the Rhine–Rhône high-speed rail line connects regions and improves their accessibility thanks to 140 km of new track, 29.1 km of which were built by Bouygues Travaux Publics.
