Hi @JeanGUAL
There is a GitHub repo GitHub - jwouellette/TPF-5_372-Unit_Test_Suite: Test instruction and IFC file repository for the BIM for Bridges and Structures Transportation Pooled Fund project which is planned to contain such files. The repo README.md and Wiki will give you more information. If you have any further questions, please feel free to contact me offline.
Right now, we don’t have any IFC files form vendors, mainly because they don’t have a final version of the AbRV base MVD which their exports are supposed to be based on. Once that is finished, I hope that files will start popping up in haste.
