Geotechnical assessments workflow

Assess the rock mass, classify ground conditions, and build a model or record over time. From underground capture on Lithos to structured geotechnical data in Strata, the workflow underground that geotechnical engineers can use while keeping up with the pace of production.

The manual gap today

Geotechnical assessments are captured underground

Geotechnical assessments are captured underground, but the records are stuck in excel sheets or notebooks. Different engineers apply and interpret conventions differently. Photographs get buried in cell phones or individual folders. When the senior geotech tries to answer "how has this drift changed over the last quarter?" or "does this ground support design match our ground control management plan", the decision relies on a conversation rather than the data.

The Workflow Stages

The connected workflow

Five stages. Two products. One connected workflow from face to decision.

STAGE 1 - PLAN - LITHOS

Define the structure

Define the structure of the rock mass assessment. headings, which framework (Q, RMR, GSI), captured and which intervals. Configure Lithos to match the assessment's requirements.

Stage 2 - Capture - Lithos

Run the assessment underground

Run the assessment underground. Location-based 3D scans in less than five minutes. Rock mass classification applied in context. Photographs linked to their spatial location.

Stage 3 - Map - Strata

The underground dataset syncs to Strata

The underground dataset syncs to Strata, where it's georeferenced, mapped, and organized. Structural features, discontinuities, and condition observations annotated directly on the mesh. Spatial relationships preserved. The assessment is queryable the same day it's captured.

STAGE 4 - DECIDE - STRATA

Decide

View data against previous assessments or within the same scene as other geotechnical data. Trends in rock mass rating, discontinuity condition, and ground behavior become visible. Support and rehabilitation decisions made against current, comparable data.

STAGE 5 - SHARE - STRATA

Export findings in open formats

Export findings in open formats for structural modeling (Leapfrog, Vulcan), stability analysis (Rocscience, Itasca), share with project stakeholders, feed into support-design reviews and RES meetings.

The Platform

How Lithos and Strata run the workflow

Lithos · data capture

Lithos for underground data capture

Use Lithos to capture geotechnical data underground with spatial context and standardized rock mass classification schemes. What's recorded in the field is what enters the record or model.

Strata · plan

Where plan meets reality

View datasets, geotechnical assessments, and perform structural mapping. The assessment record builds overtime to strengthen structural models, kinematic analysis, and finite element analysis.

What you get

Structured geotechnical assessment records

Structured geotechnical assessment records with rock mass classification values, discontinuity data, and condition observations. Comparable datasets across the project lifecycle. Exportable in open formats (DXF, CSV) for downstream analysis. A persistent assessment record that survives personnel change and project handover.

Frequently asked questions.

Data captured in Lithos flows directly into the Grounded platform, where teams can review conditions, generate reports, and align on decisions.
