Discover a more connected tunnelling workflow

Across every stage of a tunnel’s lifecycle, managing the subsurface risk is a notoriously complex business. Guiding your project to success depends on the constant availability of accurate, timely insights, from understanding the geological context to analysing the geotechnical performance of your tunnel.

With a comprehensive range of deeply connected products, Seequent powers a workflow with more clarity and control, enabling you to create a unique subsurface digital twin of your tunnel and underground assets. Bring geotechnical data, ground interpretation, physical modelling, and geotechnical design together. And give your stakeholders, at every level, the insights they need to make informed decisions.

Reduce your risk

Understand your ground risk now, then mitigate it with further investigations or optioneering before tunnelling even begins.

Improve collaboration

Give everyone access to timely insights and geotechnical documentation as new data comes to hand.

Future-proof projects

Create a subsurface digital twin now to support efficient, informed operations for years to come.

Geotechnical Data Management

Successful tunneling depends on your ability to predict ground behaviour and it all starts with the Geotechnical Data Report. But it doesn’t stop there.  Keep pace with geotechnical information through detailed tunnel design and construction.


Get more value from your geotechnical data, faster, with a secure, enterprise solution for geotechnical information management that facilitates access to factual data for analysis and modelling.

Geological Modelling

A 3D geological engineering approach bridging conceptual and observational modelling is best practice
for tunnelling projects to reduce risk and uncertainty earlier in the process, leading to better overall project outcomes.

Leapfrog Works

Fast, dynamic 3D geological modelling for combining disparate subsurface datasets with intuitive interpretation even for complex geology encountered in tunnelling.
