Tunnels & underground structures

We provide expert advice, analysis, independent checks and design review on the geotechnical performance of tunnels and underground structures — across all phases, from design through instrumentation, monitoring and long-term asset management, including both immersed-tube and bored tunnels.

Core capabilities include:

• Soil-structure interaction and ground-movement assessment
• Life-cycle asset management — translating continuous monitoring data into evidence-based maintenance and intervention strategy
• Ageing, durability and remaining-life evaluation

Our technical leadership is grounded in active European research programmes, keeping our practice at the forefront of subsurface and underground infrastructure engineering.
