The Grand Paris Express - Société des Grands Projets

For the Société du Grand Paris, Vectuel designed one of Europe's most ambitious territorial digital twins centered on the Grand Paris Express. This CIM model covers more than 12,000 km² modeled in 3D, over 2 million buildings, the 68 future automated metro stations, as well as more than 140 km² of associated urban projects.

Beyond the 3D modeling, Vectuel developed an immersive platform combining a 3D web map, films, virtual reality, and real-time visualizations. This tool enables local authorities, developers, architects, and citizens to better understand urban transformations and the interactions between transport and territorial development.

Vectuel also ensured the integration and graphic consistency of the extensive BIM and urban data produced by the project's various stakeholders. This digital twin has become a major tool for communication, consultation, and decision-making on a European scale.
