In early January 2026, we launched our new strategic plan: Trajectories 2030. This strategic plan sets out the path for a dynamic engineering organisation, committed to each project, placing transitions at the heart of our actions.

Our story is written collectively, through our projects, thanks to the women and men who make it happen.

To shed light on their work, we are launching a series of video profiles called Engineers & Citizens. These are the people who drive setec and are shaping the world of tomorrow. In this first episode, Emma-Jane Touhey and Arnaud Neuville, engineers at setec bâtiment, tell us more about the renovation of the Sainte-Geneviève Library in Paris, a project that resonates with our values: adapting a historic building to meet today’s climate challenges.
