This project is part of rehabilitating the Arena of the Agora Evry, an auditorium dating from the 1970s. This was a technically complex project for the time and required the know-how of the Baudin-Chateauneuf teams.
The first challenge of this project was to remodel the existing building as the new structure is attached mainly to it. Theoretical modeling was done based on manual plans made in 1970 by Baudin-Chateauneuf. The elements were then modified/shifted by a few centimeters with the help of a cloud of points from a 3D scan of the existing structure. This data offered us a model which closely matched reality.
During the project, permanent exchanges in IFC format were made with the civil engineering and facade designer, who made the conical glass facade, which simplified the installation of the holes of our structure created to attach glass frames.
The "study" aspect was disturbed by some confinements, but model-sharing tools ensured the continuity of work during this difficult period.
The next challenge was the manufacturing of some complex parts, such as the unstuck box beams of the monumental staircase, which was successful thanks to the Tekla part development tools for manufacturing.
A final challenge was assembling such a structure, especially with the glass-clad conical facade on which the adjustment sheet metal is small. We exported the Tekla model in DWG-3D format, allowing the TTV operator to adjust the façade using a layout station.
