Free geotechnical engineering tools

CalcForge's geotechnical tools follow a typical foundation design workflow, all checked against Eurocode 7. Start with the Bearing Capacity calculator to size a shallow foundation, or the Pile Length Estimator for driven, bored or secant piles using skin friction and base resistance. The Foundation Settlement calculator checks ground movement under a footing once bearing capacity is confirmed, and the Pad Footing tool combines the structural and geotechnical checks for a concrete pad in one design. For retaining structures, the Retaining Wall calculator designs a concrete gravity wall, the Braced Excavation tool checks a cofferdam supported by sheet piles or secant piled walls, and Anchored Excavation adds ground anchors to that same retaining problem. The Slope Stability calculator finds the critical slip surface and factor of safety for a soil or rock slope. All eight tools are free, open source, and export a PDF calculation report.

Yes. Every tool linked from this page runs a free calculation with no sign-up required. Creating a free account additionally lets you save a design and, on most calculators, export a PDF report — a small number of deeper analysis features are reserved for a paid tier, noted on that calculator's own page.

You don't need to be a developer to publish one. Our Python for Civil Engineering certification (enrol here) walks you through building and publishing four tools like the ones on this page, using the same open-source engineering libraries CalcForge itself is built on.
