Operate & Maintain Tunnel

Surveyors document and monitor tunnels in real-time, detecting potential issues before they arise.



Learn how deformation monitoring can provide real-time information to ensure the safety and integrity of infrastructure.

Surveyors help ensure the safety of surrounding infrastructure and document tunnel conditions to create a digital model for analysis and improved decision-making.


Create digital twins of tunnels with mobile mapping

Surveyors play a crucial role in documenting tunnel assets with precision, ensuring safe and efficient operations, maintenance, and upgrades. Our advanced 3D Mobile Mapping solutions with SLAM (Simultaneous Localisation and Mapping) offer an autonomous and safer solution for creating digital twins of tunnels. With automated data processing, our technology autonomously identifies and extracts features, streamlining the mapping process.

Our mobile reality capture solutions simplify calculations of clearances, tunnel geometry, profiles, and other critical parameters, enabling automated maintenance and operation of the tunnel. Create a digital model of the tunnel and its associated assets, facilitating collaborative assessments, faster decision-making, and efficient maintenance and repair activities.

The complete solution for tunnel monitoring

In urban environments where space is limited, subterranean expansion through tunnelling projects offers a solution for accommodating growing infrastructure needs. To ensure continued operational efficiency and safety of tunnels, deformation monitoring is required.

Leica Geosystems tunnel monitoring solutions provide real-time insights into ground movements and tunnel distortions. By combining geodetic, geotechnical, and environmental sensors, our Total Monitoring approach offers a complete understanding during tunnel operations.

Keeping the public safe when commuting via tunnels

Safety during tunnel operation is crucial and it requires comprehensive coverage to ensure the entire tunnel environment is monitored effectively.

Leica Geosystems helps address security challenges with its smart 3D surveillance system, detecting physical changes in a space immediately and determining threats with accuracy and reliability. Furthermore, notifying the relevant personnel accordingly reduces false alarms and increases overall confidence in your security system using advanced AI software.

Reduce time and cost, and increase productivity


Maximise efficiency and minimise downtime

Mounted on a vehicle, the Leica Pegasus TRK solution with integrated IMU and SLAM technology captures a 3D laser scan point cloud and 360° imagery to create a digital twin of the tunnel. Safe operation is ensured by remotely measuring inaccessible/dangerous areas, and road or track interruptions are minimised by rapid data collection. Leica Geosystems mobile mapping systems empower you to capture data efficiently over long distances and are more complete compared to conventional surveying techniques.

Autonomous information extraction for asset inventory and clearance analysis

Cyclone MMS DELIVER takes as input the trajectory information, point clouds with all meta information, and imagery previously processed with Cyclone Pegasus OFFICE. An easy object recognition transforms the data into asset inventory and actionable information. For both road and rail tunnels, autonomous information extraction allows clearance analysis for 2D and 3D profiles. The extracted information is delivered from unattended batch processing routines into industry-standard formats that can seamlessly be shared among multiple offices and collaborators.

 

Contactless GPR data collection for tunnel inspection


Maximise safety with regular GPR tunnel inspection

Stream T is the most advanced solution of the successful measurement of tunnel lining thickness, mapping of reinforcing, detection of cavities, and location of wet areas. Boost productivity with higher acquisition speed, maximise operator safety with the remote-controlled mechanical arm, cover larger areas with antenna footprint up to 100 cm, and meet the inspection requirements with the Stream T modular structure.

Manage tunnel project risks with scalable monitoring solutions


Increase safety onsite and keep investments low with manual monitoring

Keeping people and assets safe is critical during tunnel life operation. Detect deformations after tunnel construction and take precautionary action with Leica Geosystems monitoring solutions. When risks are low and access is not limited, manual campaign monitoring is typically undertaken with existing equipment such as LS15 digital level or TS16 total station ensuring small investments.

Improve efficiency and minimise risks with semi-automated monitoring

When a higher risk is expected, or access is limited during tunnel operation, people, infrastructure, and assets can be kept safe with semi-automated monitoring. Measurements and analysis are conducted semi-automatically, minimising human error, optimising data capture and workflow without the need to have personnel performing manual measurement onsite using a highly accurate total station or MultiStation, with Leica TPS monitoring app, and Leica GeoMoS Now! Survey Edition. Results can be visualised and reported online to speed up the process to ensure any movements are quickly identified and actions are taken to keep all personnel safe.

 

Enhance safety with real-time monitoring

For complete peace of mind, deploy Leica Geosystems' real-time monitoring solutions. Automated monitoring is the right choice for tunnel projects with a high risk of movement and in locations where accessibility is dangerous. Points can be identified and automatically measured either by total station, MultiStation, digital level, GNSS, or geotechnical sensors, and checked for deformations. Real-time notifications are issued, and experts can immediately decide to evacuate areas at risk. Keep tunnel operation and surroundings safe with Leica Geosystems monitoring solutions that continuously inform stakeholders.

 

Real-time threat detection to improve tunnel safety operation

For safer tunnel operation the Leica BLK247 provides smart 3D surveillance system that immediately determines threats versus non-threats with accuracy and reliability. The system reduces false alarms and increases overall confidence in your security system.
