Tunnel Glion Copyright a demander OFROU TBD


In response to the increased mobility, rapid urban densification, natural obstacles, noise pollution and environmental impacts generated by motorised traffic, roads are using more and longer tunnel sections than before. Furthermore, the coexistence on country and city roads of different modes of transportation – cars, bicycles, trams, trains – means that special attention must be paid to safety.

Additionally, the high increase in traffic is encouraging public officials to modernise existing infrastructure, particularly their electromechanical equipment, so as to meet growing demand and fulfil new requirements, especially those relating to safety. Major maintenance, repair and construction work on tunnels is ongoing, while others are already planned for the years to come. These works have and will continue to have a non-negligible impact on road traffic and also involve a large financial and human investment. In order to optimise this investment, a prior risk and needs assessment, particularly in terms of safety and equipment, as well as appropriate design of the equipment used and concerted planning of the work, are essential.

Our experienced specialists, whether alone or accompanied by partners who broaden the range of services we offer, are in a position to perform this prior assessment and consequently define the needs in terms of electromechanical equipment, ventilation and safety. Next we cover all phases of the project, from design to commissioning tests, first for safety and tunnel ventilation equipment– our historic activity – but also for the other electromechanical equipment as well as for level crossings.
