Your partner for tunnel construction and operation
Sixense offers monitoring, scanning, noise and vibration consultancy, geophysics, and structural engineering services for your tunnels and the surrounding environment.
Discover our solutions and achievements on tunnel projects in urban and non-urban environments for transport purposes: pedestrian, metro, rail, road, canal, etc.
The Sixense team is at your disposal with extensive experience in dug, covered, and bored tunnels with masonry, concrete, and steel structures.
Sixense solutions for tunnels
We bring our expertise to all phases of a tunnel’s life cycle: studies, design, construction, operation, and maintenance.
Our services apply to tunnels under construction and in operation with pathologies or affected by adjacent construction:
Monitoring
Design, supply, install, operate, and maintain small and large monitoring programs during underground construction and for tunnels in operation.
Monitoring concerns both soil-structure behavior and environmental issues (noise, vibration, dust, etc.).
Our range of techniques is extensive, from sensors sealed in the ground to measurements made from satellites.
Digitalization & modeling
Mapping and 3D modeling to bring dimensional information and precise knowledge of construction sites and live structures.
Audit inspection
Methods for tunnel inspection, aiming to improve visit efficiency and rating representation. Sixense masters digitalized inspection from acquisition to analysis.
Geophysics & soil characterization
Sixense offers all ground-based geophysical investigation methods to detect disorders, voids, anomalies, faults, or obstacles in the ground.
Environmental and acoustic consultancy
Our engineers assess the level of nuisance during construction (tunnel boring, blasting operations) and operations (traffic, etc.) and advise on mitigation measures.
Tests on concrete structures & laboratory tests
Assess the structure’s condition, especially the lining.
Data is collected using Non-Destructive or Semi-Destructive methods.
Samples collected on-site are sent to Sixense’s laboratory, to analyze the mechanical, physical, or chemical properties of the materials, as well as their pathologies.
Engineering of existing structures
Our engineers analyze pathologies, develop rehabilitation, or repair studies and help owners and operators to optimize the maintenance plan.
Climate resilience
Our Resallience team will support you in adapting to climate change.
Digital simulation model
Sixense has developed complex and accurate algorithms to simulate the significant stresses applied to tunnel structures, such as fires, explosions, earthquakes, or impacts.
