Engineering structures and tunnels
Engineering structures and tunnels are essential links in the infrastructure network, and they represent a major challenge for the community.
Their design and maintenance represent a safety and economic development priority, aimed at maximising their lifecycle, as well as having a significant environmental impact.
Setec teams offer clients multidisciplinary expertise in a wide range of projects, including engineering structures and underground works.
Specialist skills and know-how are developed to meet the specific requirements of the projects assigned to them. Through innovation, the development of advanced calculation models and the use of the most appropriate technologies, they can optimise the use of materials and, consequently, the carbon footprint and cost of structures.
Setec provides complete design services and manages the construction, renovation and modernisation of major engineering structures and numerous road, rail and other tunnels. Technical excellence and the commitment of our teams mean that setec is involved in a wide range of emblematic projects, both in France and abroad – from the Channel Tunnel to the Grand Paris Express, not forgetting the Millau Viaduct and the Normandy Bridge, the third bridge over the Bosphorus, the Mohamed VI bridge in Rabat, the cable-stayed bridge in Brazzaville, the 4th bridge in Abidjan and the Euralpin tunnel between Lyon and Turin, where the project includes the reuse of excavated materials to produce concrete aggregates for the tunnel.
We work alongside specialists in all disciplines (geotechnics, hydraulics, structures, materials, environment, safety, traffic management equipment, etc.) involved in the design and construction of these structures.
Setec has also gained recognised expertise in the field of existing structures, providing diagnostics, design and works supervision for the repair and reinforcement of civil engineering structures of all types.
Setec is the first engineering company to have performed complete tunnel inspections as defined in the new Fascicule 40 of the Technical Instruction, combining skills in civil engineering, (electricity/barriers/detectors, geotechnics/geology and equipment/fans/accelerators).
Tancrède de FOLLEVILLE Project Director setec TPIIn recent years, the development of soft mobility and the creation of bicycle paths across the country have given a real boost to the market for pedestrian bridges, in both urban and rural areas. The repair and rehabilitation of existing engineering structures also remains a major challenge in terms of safety and heritage preservation, following the disasters that have occurred in recent years (Genoa bridge, Mirepoix bridge, etc.), while international markets can offer excellent opportunities for the construction of major new structures, particularly in emerging countries.
