Your team inspects the tunnel every day. Your engineers need that data for support decisions, baseline reviews, and reporting. The current workflow was not built for the pace of production.
Tunnel scanned. Features mapped. Geological and geotechnical conditions documented for the next push.
Sketches photographed. Notes transcribed. Data re-entered intospreadsheets hours or days later, if it gets there at all.
Engineers and managers work from yesterday's data on today's conditions. Owners ask for records that take days to compile.
Standardize geotechnical data capture underground. Consistent inputs feed directly into support class decisions, design validation, and construction records.
Document divergence from baseline conditions in real-time underground, with structured data. Build the record as it happens, not weeks later in the office.
Capture discontinuities, joint orientations, and structural geology underground. Maintain a continuous geological record tied to chainage and advance.
Prepare for Required Excavation Support Sign-off with complete, current data linked tothe specific chainage and conditions under review.
Geological records that keep pace with daily advances.
Differing site conditions documented in real time, not reconstructed.
Client-ready reporting built from structured field data, not manual assembly.

"On a tunnel project, you don't get to go back. If the geological record doesn't keep pace withconstruction, you're documenting from memory — and that's not a record, it's an estimate."
Reduced decision-making time for ground support design

Connects face data to your surface workflows, mapping to chainage, reporting to owners, andtransfer to engineering tools. Export structured data directly into your modelling platform.

Data captured in Lithos flows directly to Strata Grounded platform, where teams can review conditions, generate reports, and align on decisions.
Capture the encountered conditions in 3D underground with Lithos, georeference them against the planned alignment, and build a persistent record in Strata that documents what was found and when. Export this data to compare against the GBR.
Yes. The capture workflow adapts to the construction method, face mapping for SEM/NATM advances, segment and ground support and/or ring documentation for TBM projects. Strata holds the same chainage-based record across both.
Yes. Data can be exported as georeferenced textured mesh files and annotated polylines which are compatible with BIM-software models.
