The Grand Paris Express - Société des Grands Projets

For the Société du Grand Paris, Vectuel has designed one of Europe's most ambitious regional digital twins around the Grand Paris Express. This CIM model covers over 12,000 km² modeled in 3D, nearly one million buildings, the 68 future automatic metro stations, as well as over 140 km² of associated urban projects.

Beyond the 3D modeling, Vectuel developed an immersive platform combining 3D web maps, films, virtual reality, and real-time visualizations. This tool allows 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 graphical consistency of the numerous BIM and urban-level 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.
