Four architecture firms will use Autodesk’s 3D model to reimagine the area surrounding the Eiffel Tower.
also revealed the four teams that have been selected to compete to reimagine the area: • Gustafson Porter + Bowman and BIM Services; • AL_A and Quatorze-ig; • Agence ter and Arcadis; and • KOZ Architectes. During the next year, Autodesk will work with the teams to visualize their designs for the Eiffel Tower grand site, giving them access to a simplified version of the 3D model to use during the different stages of the competition process. The model will help illustrate visibility of project design components from various lines-of-sight and viewpoints, helping the teams to create individual proposals for the future urban space. Additionally, the model will be used by a jury panel during the final judging of the four proposals to better understand them. The four designs will be unveiled in spring 2019, and construction of the winning project will start in 2021. Renovation of the Eiffel Tower area, covering the Trocadéro Gardens and the Champ de Mars, will be finalized just in time for the 2024 Summer Olympics, and ahead of other major events including the 2025 Universal Exhibition and the 2026 Rugby World Cup. While the makeover will make the area more pleasant for visitors, the project isn’t just a cosmetic effort. The Parisian metropolis needs to address growing challenges relating to energy, greening, supply net- works, mobility, logistics, waste management, and security of the area. Not only that, but with Paris renowned for flooding and climate scien- tists expecting this to increase, the city is taking necessary pre-emptive measures to prevent future damage. Worldwide impact While this project may be taking place in Paris, Autodesk hopes its im-
A 3D model created by Autodesk will be used during restoration of the Eiffel Tower grand site — all 2.4 square kilometers of it. The model will be used by the Paris Council to engage with the public during the design and construction process, allowing Parisians and tourists to ex- perience the Eiffel Tower like they never have before — in virtual 3D. Autodesk is the sole technology provider collaborating with the City of Paris on this project and used Building Information Modeling (BIM) to create the largest urban model of its kind worldwide, complete with buildings, roads and infrastructures, pedestrian zones and crossing, urban furniture, and green areas. The sheer scale of the project has been an exciting challenge for the Autodesk team tasked with creating the data-set of the 3D model. Mapping the details of the 2.4-square-kilometer site required LiDAR scanning to generate 194 point cloud tiles, aerial photography that is precise to the nearest 2 to 5 cm depending on areas, and creation of 342 GB worth of point cloud data (10.3 billion points), all of which can be used to create models in both Autodesk InfraWorks and 3ds Max. Competing to reimagine the Eiffel Tower grand site At an event held in Paris’ City Hall, Jean-Louis Missika, deputy mayor of the City of Paris, in charge of urban planning, architecture, Grand Paris projects, economic development, and attractiveness; and Jean-François Martins, deputy mayor of Paris, in charge of all questions relating to sport, tourism, Olympic and Paralympic Games, Eiffel Tower restoration Four teams are using a detailed 3D model to reimagine a section of Paris in preparation for the 2024 Summer Olympics.
