Creating a sustainable future.

We work side by side with clients on every step of their journey. Across every aspect of transport, infrastructure and the built environment. All around the globe. 

Together we’re building a smarter, greener world and creating a sustainable future for communities everywhere. 

Our history and ownership.

Founded and headquartered in France, our roots go back to the pre-war period. 

The group has evolved over the past 90 years to encompass transport, infrastructure engineering and building engineering. Now 62% of our work is outside France, with a close-knit and fast-growing network of offices across every continent. 

Three key players are shareholders in our Group: Tikehau Capital (40%) via its T2 Energy Transition fund, Caisse des Dépôts (34%) and its partner managers and employees (26%) through Egis Partenaires and a Corporate Mutual Fund share.

Global perspective. Locally connected.

Creating a sustainable future means understanding both the big picture and the local complexities. 

This is why we have nurtured a tight-knit network that spans the entire planet. Wherever we’re based, we’re part of the ecosystem. We co-create with our clients. We partner with start-ups, governments and research organisations. 

Our people live in the same communities where they work. They understand the local issues and love to use their knowledge to make a lasting difference.
