A multitude of companies are producing BIM models for the EOLE project, with approximately 190 people who are directly involved in producing models of diversified disciplines, such as tracks, signalling and catenary. So, this number is increasing as the model is becoming more elaborate. Thirty-three per cent of the clashes are being detected using BIM, but this number is not quite accurate because, at first, our model was not at a sufficiently advanced stage to let us detect the clashes using it, and this number takes into consideration clash detection since the beginning of the project. The global model is composed of 300 models, 13,000 objects and 31 sub-projects. The part of the project that is being managed using Building Information Modelling (BIM) is 10km long.
