From the Autodesk blog:
“As part of the partnership, Autodesk will create a digital 3D model of the existing Eiffel Tower grand site and will support the selected teams with the development and visualisation of their designs.
The 3D model will enable the City of Paris and the project management teams to design, visualize, simulate and collaborate more effectively throughout the competitive process. It will also allow the jury and the City of Paris to visualize, evaluate and understand the projects submitted by the candidate teams in 3D, and to analyse them more easily throughout the entire workflow from design to construction.
Thus, the use of BIM (Building Information Modeling) has been made mandatory for the teams who would like to compete.
With this visionary approach, the City of Paris is embracing advanced technology to not only improve the redesign and construction of the surrounding areas, but also for deploying technology to encourage greater public participation.”
