The Workflow Advantage

Data Enters Once. Goes Everywhere.

In traditional projects, investigation data passes through multiple teams and gets re-entered multiple times — creating errors, delays and inconsistencies.

At Trilogy, field data captured digitally flows directly into our 3D modelling environment. Drone surveys feed into volumetric models. Borehole data feeds into PLAXIS. Environmental sampling feeds into contamination extent models.

By the time the field program is complete, the model is ready. Investigation and design run in parallel — not in sequence. This accelerates project decision-making and reduces project uncertainty by giving project teams a single, current model to work from.

Step 1 — Digital Field Capture

All data captured digitally on site. No transcription, no paper, no re-entry. Data flows immediately into the modelling environment.

Step 2 — Real-Time Model Building

3D models updated as data arrives. Ground conditions interpreted in real time — investigation strategy adapts immediately.

Step 3 — Design-Ready Output

On completion of the field program, models are ready for PLAXIS, Slope/W, GIS and structural design. No separate modelling phase required.

3D Modelling in Practice

Real Project Outputs

From service-integrated backfill models to large-area geological models and digital twins — Trilogy's 3D modelling capability spans environmental, geotechnical and civil disciplines, all built from real field data.
