Tunnels
Underground works are some of the most technically challenging projects. Our team brings expertise in geotechnical assessment, groundwater management, and risk reduction to make tunneling safer and more efficient.
Common Challenges in Tunnels
CHALLENGES
Urban tunnelling projects face some of the most complex geotechnical and environmental risks—groundwater inflows, settlement impacts on sensitive structures, and the strict safety demands of confined underground works.
1.
Uncontrolled inflows can stall excavation and increase risk to workers and adjacent assets. We deliver hydrogeological modelling, dewatering strategies, and waterproofing solutions to manage groundwater safely.

2.
Settlement Impacts on Nearby Structures
Urban tunnelling can affect sensitive buildings, utilities, and transport corridors above. We assess settlement risk, model potential ground movements, and design mitigation to protect critical infrastructure.
3.
Ventilation, Safety, and Access Constraints
Confined underground works demand strict safety controls. We design ventilation, access, and monitoring plans that safeguard crews and meet regulatory requirements.
4.
Managing Risk in Urban Tunnelling
Complex ground, stakeholder scrutiny, and tight corridors amplify risk. We integrate geotechnical and environmental assessments with robust monitoring and responsive support to keep projects compliant and on program.
Comprehensive site investigations, 3D modelling, and groundwater assessments that define conditions for safe and efficient tunnel design.
