Ground-related risk assessment
Tunnel failure investigation
Developing remedial and maintenance solutions
Delivery of specialist tunnelling works
Construction supervision and technical assurance
Specialist technical advisory services
Our experience covers both new underground construction and the inspection, assessment and maintenance of existing tunnel assets. We consider the interaction between the tunnel structure, surrounding ground, groundwater, joints, connections, services and operational loading.
This combination of design, construction and asset-assessment experience enables us to identify the structural significance of defects and develop practical engineering recommendations that reflect actual site and operational constraints.
Where required, Tunnel Engineering can support the implementation of the developed solution through construction planning, temporary works, specialist supply-chain coordination, site engineering and technical supervision.
