Today, we witnessed the official launch of a groundbreaking 3D model created by Autodesk for the restoration of the Eiffel Tower’s grand site—an impressive 2.4 square kilometers of Parisian urban space. This digital model will serve as a powerful tool for the Paris Council to engage with citizens and visitors throughout the design and construction phases. It offers an immersive virtual experience, allowing people to explore the Eiffel Tower and its surroundings in stunning 3D, opening up new ways to interact with one of the world's most iconic landmarks.
Autodesk is the exclusive technology partner working with the City of Paris on this ambitious and unique project. Using Building Information Modeling (BIM), they’ve developed the largest urban BIM model ever created, encompassing everything from buildings and roads to pedestrian zones, green spaces, and urban furniture. This comprehensive digital representation is set to transform how cities plan and manage large-scale urban environments.
The scale of this project posed a major challenge for the Autodesk team. To accurately capture the entire area, they used LiDAR scanning to generate 194 point cloud tiles, aerial photography with precision down to 2-5 cm, and produced 342 GB of point cloud data—equivalent to 10.3 billion points. These datasets are now being used in Autodesk InfraWorks and 3ds Max to create detailed and realistic models of the site.
At a recent event at Paris City Hall, Deputy Mayor Jean-Louis Missika and Deputy Mayor Jean-François Martins announced the four teams selected to reimagine the Eiffel Tower grand site. The finalists include Gustafson Porter + Bowman and BIM Services, AL_A and Quatorze-ig, Agence ter and Arcadis, and KOZ Architectes. Over the next year, Autodesk will support these teams by providing them with a simplified version of the 3D model to help visualize their designs. This will aid in evaluating visibility, spatial relationships, and overall feasibility of each proposal.
The final designs will be unveiled in spring 2019, with the winning project set to begin construction in 2021. The renovation, which includes the Trocadéro Gardens and Champ de Mars, is expected to be completed in time for the 2024 Summer Olympics and ahead of other major events like the 2023 Rugby World Cup.
This transformation isn’t just about aesthetics—it’s a strategic move to address key urban challenges such as energy use, sustainability, mobility, logistics, and climate resilience. With rising concerns about flooding and climate change, the city is taking proactive steps to ensure long-term safety and efficiency.
As a global leader in BIM and digital construction tools, Autodesk hopes this project will inspire other cities and countries to embrace digital technologies. The Eiffel Tower initiative showcases how BIM can streamline processes, reduce waste, and improve collaboration across teams. Nicolas Mangon, Senior Vice President of AEC Strategy at Autodesk, emphasized that “this project is a powerful example of how digital tools can drive innovation and reshape the future of the AEC industry.â€
With thousands of hours of data collection, 10.3 billion points, 8,200 trees, 1,000 buildings, and over 25 statues modeled, this project stands as a testament to the power of digital engineering.
