The contract includes the services of a noise specialist for the AP phase (according to the Tracé/Environnement manual, FHB T/U, ASTRA 21001) of the project Upn.Vennes-Chexbres+PUN Within the framework of the UPlaNS Vennes-Chexbres project, the section must be adapted with regard to road noise. To this end, two public consultation procedures with Noise AP were carried out in 2016 and 2018. In the course of processing objections to the plan approval, the Federal Administrative Court ordered an additional public consultation to adapt road noise protection between km 7.188 and km 15.100, taking the following points into account: • The construction of the R-BAU Vennes-Belmont constitutes a material change. • The speed could be reduced to 100 km/h at any time or only at night. The present invitation to tender concerns the adoption and updating of the models prepared within the framework of the 2016 and 2018 studies, as well as the preparation of a new AP to comply with noise protection regulations. Since this is an update of an existing file, the StL-86+ model is used and the traffic planning horizon remains 2040.
