Design & Capture for Tunnels

Provide accurate and reliable survey control networks for positioning confidence and capture the reality within, around, and above tunnels to visualise and analyse complete information.



Try Leica Infinity with your tunnelling data.

Tunnelling demands surveyors to have the best techniques and deliver the highest accuracy. You can rely on our solutions to satisfy those requirements with easy to use, powerful solutions.

Start tunnel construction with confidence

An accurate survey control network is paramount for assuring on-target machine guidance and highest accuracy “breakthroughs” in tunnel construction.

Leica Geosystems takes pride in offering the most accurate and robust equipment suited to the harsh environment often associated with tunnelling, complemented by state-of-the-art software. Our solutions integrate data from various sensors, providing the highest levels of accuracy for measurement and network computation.

Efficient and complete data collection

Surveyors play an important role in the design phase for tunnels by providing condition surveys, assessments, and topographic and utility mapping. Our solutions enable surveyors to measure and analyse terrain, existing structures, and the surface features, aligning them with the geological and geotechnical underground data for the tunnel design.

With our best-in-class total stations, reality capture surveying solutions, and advanced software, surveyors can collect data rapidly, comprehensively, and safely. Choose our tunnelling solution when you need a robust workflow that provides complete data.

Preparing tunnel design for the field

Leica Geosystems solutions provide advanced surveying software that facilitates seamless collaboration and efficiency in design analysis, data preparation, and office-to-field data exchange. Our software allows simple tunnel design creation with easy import and editing of designs from industry-leading formats, enabling tunnel data preparation and analysis. Before being sent to the field, the design can undergo thorough review and quality checks, ensuring correctness.

Our solutions maximise data collaboration and enable a seamless workflow between the office and field software. The software offers enhanced productivity and efficiency through effortless IFC model conversion to tunnel cross-sections and profiles, reducing errors and simplifying the process. The prepared design data can be directly shared with stakeholders in the field, ensuring flexibility and smoother communication.

Establish high-quality survey control


The most accurate total stations, reliable GNSS, and field software

Leica Geosystems provides a complete portfolio of total stations with the most reliable angular measurement and GNSS solutions to ensure that tunnel projects start with the most accurate control. Leica Captivate software delivers rigorous results in the field to ensure confidence before leaving the site.

Industry-leading accuracy with Leica Geosystems digital levels

Leica Geosystems’ digital levels provide best-in-class accuracy. Maximise efficiency and minimise user fatigue with image-assisted aiming and autofocus. Onboard applications ensure results can be verified onsite to avoid costly revisits.

Rigorous network adjustment

Once data collection is completed for the site control network, final coordinates are delivered after a network adjustment. Both Leica Infinity and MicroSurvey STAR*NET are designed to integrate measurements from all sensors to provide a rigorous network adjustment. Adjusted coordinates can be shared with field teams via GeoCloud Drive, powered by HxDR  or directly uploaded for onsite use.

Capture accurate and complete digital twins


Point-by-point survey to map the site conditions

Capturing detailed site conditions is essential to create accurate designs before progressing with construction activities. Maximise efficiency with the Leica TS16 and the Leica AP20 AutoPole or capture images with visual positioning with Leica GS18 I and create a point cloud in Leica Infinity. With Leica Captivate field software, you can capture all point and line features in the field to ensure minimal post-processing in the office and create deliverables ready for design activities to begin.

Laser scanning and mobile mapping for safety and efficiency

For higher efficiency and speed, the Leica RTC360 3D laser scanner has a measuring range of up to 130 metres and a scanning rate of up to two million points per second. Point clouds from laser scanning provide a detailed digital twin that allows tunnel design to begin with confidence. When long-range scanning is required at a safe distance, the Leica ScanStation P-Series delivers high-quality 3D data, collects up to 1 million points per second, and ranges up to 1 km. The Leica Pegasus TRK offers a highly efficient mobile mapping solution for creating digital twins. Surface cracks can be easily identified with a unique imaging solution.

Superior productivity in underground utility survey

Safety is paramount in construction, and knowing everything about the site before beginning construction is essential to ensure safety. Easily detect and map underground utilities with the Leica DSX utility detection solution. The Leica DSX maximises productivity with cutting-edge software that automates data analysis and creates a 3D utility map in the field. For greater depths use the Stream DP, a revolutionary, multichannel Ground Penetrating Radar (GPR). An array solution for real-time mapping of underground utilities, the Stream DP offers state-of-the-art features for underground surveys. For large areas, Stream UP maps underground utility assets at high speed in urban environments faster and safer than any other GPR system.

Design, visualize, and collaborate effectively


Collect, process, visualise, and review

Leica Infinity is a central hub that merges and processes data from various sensors. Using the dedicated tunnel module, import designs from industry leading formats and create and edit tunnel data. The design can be reviewed and quality checked before being prepared and sent directly to Leica Captivate with GeoCloud Drive, powered by HxDR .

Unlock deeper insights for your tunnel projects

HxGN Content Program is the world’s largest database of consistent, high-resolution aerial imagery, elevation data, 3D models, and analytics across the United States and Europe. The unprecedented quality is an ideal base for machine learning and AI applications to extract features and classify objects. The airborne imagery is available in 15 cm resolution in urban areas and 30 cm in wide areas. Professional-grade cloud-free imagery can be streamed or downloaded to facilitate your initial design, planning, and assessment of project feasibility.


Customer success stories


Gotthard Tunnel - Leica Geosystems Heavy Construction Solutions

Gotthard Base Tunnel, world’s longest and deepest rail tunnel, benefits from Leica Geosystems

Surveying consortium VI-GBT drilled a 57 kilometre long tunnel from both sides and met in the middle with a deviation of only 8 centimetres or 3.1 inches, whereas 25 centimetres or 9.8 inches would have been tolerated. Surveyors captured this engineering marvel by repeating surveying and measuring tasks every 400 meters, ensuring the tunnel was precisely on course.
