Data transfer and preparation
You provide the project, investigation and terrain data needed for the work. We check the data for completeness and technical usability, then organise the relevant information for digital modelling.
Digital 2D and 3D ground modelling
GEONOVA creates digital 2D and 3D ground models based on direct and indirect investigation data. Our service includes the structured preparation of your investigation data, followed by modelling and visualisation of the ground layers, including inclusions, lenses and bands. Save time on ground modelling and focus on your geotechnical assessment; we handle the digital implementation.

Geotechnical calculations
We are extending our services to include geotechnical calculations based on digital ground models. Stratigraphy and soil parameters are evaluated for the task at hand, from simplified calculation models to the investigation of different spatial realisations.
Prices for geotechnical calculations on request.

From project data to a digital ground model
GEONOVA prepares, models and visualises your geotechnical project data. The work follows five clearly defined steps.
Input
Project data · investigation data · terrain data and elevation references
Modelling and visualisation
Using the data provided, we create the agreed 2D and/or 3D ground model. We visualise the model and make it available to you in a web-based project view.
Section creation
We create the agreed geological 2D sections from the digital ground model. Their alignment follows the project requirements or the instructions agreed with you.
Review and adjustment
You review the model and the sections. One additional revision or adjustment round is included in our standard services. We then incorporate your requested changes into the model and its associated deliverables.
Deliverables through the web portal
After the work is complete, we make the agreed project data available through the GEONOVA web portal.

Between observations, there is more than one solution
An interactive exploration shows how observations become a model – and what remains uncertain between them. Compare methods, follow a survey and explore linked 3D views.

From ground model to calculation
Three ways to use spatial ground information
A 3D ground model improves understanding of subsurface conditions. It can also form the basis of geotechnical calculations. The appropriate approach depends on the engineering task, the structure and the available data.
Derive clusters of calculation models
Areas, or “clusters”, are defined in plan. For each area, a separate conservative calculation model is derived for each geotechnical task. Its layer boundaries and parameter values cover the adverse ground conditions in that area that govern the task. Where ground conditions are very uniform, a single calculation model for the entire construction project may be sufficient for the particular task.
Calculate locally, interpolate the results
The geotechnical task is calculated at locations using the stratigraphy known there from the ground investigations and the associated parameters. The results are then interpolated between calculation locations. This reveals the spatial distribution of a result; the suitability of that interpolation and areas with abrupt changes require separate assessment.
Calculate directly within the 3D model
The spatial models themselves provide the calculation geometry, and each realisation is meshed individually. Different possible realisations of layer boundaries, lenses and spatial parameter distributions reveal their effect on the results. The spread describes the variants investigated and can be used to interpret the expected results.
Task-specific envelopes are derived for conservative models, for example for pile locations that require separate assessment. They must be distinguished from individual possible layer profiles. Their selection depends on the verification concerned.
Principle illustrated: settlement of a silo base slab
This example uses the ground data of the DGGT example. Here, an elastic silo base slab without piles is analysed. One hundred possible ground realisations illustrate how spatially varying layer boundaries, silt lenses and soil stiffness affect settlement and inclination.
Between investigation points, layer boundaries undulate randomly and moderately about their interpolated positions, with one to three periods. The specified levels at the investigation points remain unchanged.
This example is intended solely to illustrate the principle.
