Complex-technology project involving extensive 3D design work
The pre-design work done by VS-A set the basis for the structural design. In the execution phase, design office Charpente Concept adapted these principles to produce assembly details and construction drawings.
Gontran Dufour, associate director and joint managing partner of VS-A design office explains: "We discussed structural efficiency and produced analyses with our modelling and calculation systems to identify the most appropriate solution. In particular we worked extensively on the layout and all the design process was done in 3D, which was necessary due to the complex shape of the building. "
Antoine Roux from Charpente Concept explains: "This project is really exceptional, not just because of its size but also because of its shape. With its members’ curves, its dimensions and wide opening in the roof for the track and field area, very few pieces could be identical.”
He continues: "We had to size and design the whole building in 3D. It took 3,000 hours of design work to produce the 4,000 construction drawings. They can now be reused at different scales."
Cedric Roux, Manager of the Poulingue Design Office, concludes: "The 3D modelling process enabled us to export information of the elements to be used for manufacturing process. "
