Geotechnical Design Tool
Everything you need for foundation design, from ground investigation to final report.
Layer-by-layer input with interactive stratigraphy visualization, groundwater level, and parameter validation.
Elastic and consolidation settlement for granular and cohesive soils with time-rate curves.
Drained and undrained analysis with EC7 factors, shape/depth/inclination corrections.
Full support for DA1-C1, DA1-C2, and custom partial factor configurations.
Automatic detection of missing inputs, common pitfalls, and reviewer checklist generation.
Full traceability with inputs, equations, intermediate results, and disclaimers.
Built-in database of typical UK soil and rock parameters including London Clay, Glacial Till, Chalk, and more. Clearly labeled as illustrative values for preliminary assessment only.
| Parameter | Min | Typical | Max |
|---|---|---|---|
| γsat (kN/m³) | 19 | 21 | 22 |
| φ' (°) | 20 | 23 | 25 |
| cu (kPa) | 50 | 100 | 200 |
| Eu (MPa) | 20 | 50 | 100 |

This tool is intended to assist qualified geotechnical engineers in their design work. All calculations should be verified independently. The reference database contains illustrative values only and must not be used for detailed design without verification against site-specific investigation data. Users accept full responsibility for the appropriateness of parameters and methods used in their designs.
