TerraBrains is the operating system for geotechnical engineering. Capture boring logs offline on any tablet, run 213 code-checked analyses and 47 lab workflows, build a true 3D ground model with AI geological interpretation, and let AI draft your report — every claim cited. Sign deliverables that lock to a tamper-evident SHA-256 audit chain.
We are not replacing your CAD. We are replacing the spreadsheets, the email threads, and the “final-FINAL.pdf” chaos between them.
Borehole logs, SPT, samples — entered on a tablet that survives loss of signal, water, and gloves. Attach photos, voice notes, and scan sample barcodes. An offline outbox replays every record in order the moment you come back online.
Atterberg, sieves, triaxial, consolidation, and 43 more — each test queues into a real workflow with results that auto-classify and link straight back to the source sample.
AI drafts an engineer-grade report — every claim cited to a borehole, lab result, or standard clause. Section diff, request-changes review loop, finalisation gate, then sign-and-stamp locks it to the immutable audit chain.
Where field-ops tools stop at a clean PDF, TerraBrains computes the engineering — 213 code-checked analyses, a true 3D ground model, and an AI that interprets it — all from the same boreholes, all citing their source.
Bearing capacity, settlement, piles (bored · driven · lateral · group), liquefaction, soil & rock slope stability, seepage, retaining & excavation systems, ground improvement, the full flexible + rigid pavement suite, tunnels and in-situ CPT / DMT / pressuremeter — to IS, Eurocode 7, NF P94-261, BS, AASHTO and ASTM. Not lookup tables: rigorous engines whose every result cites its governing clause, is covered by the golden test suite (149 suites benchmark against published worked examples, and counting), and has been adversarially stress-tested for the inputs that break lesser tools.
No other geotech tool does this. Beyond the number, every design analysis returns a verdict — adequate, marginal, inadequate or over-conservative — the governing criterion (the exact IS / IRC / EC7 limit), and the concrete next step: widen the base, thicken the slab, raise the factor of safety, found below the frost line. It reads on web, mobile and the AI assistant, so juniors learn the why and seniors move faster.
Four premium suites you attach to any plan: the Pavement Suite — a complete, time-stepping Pavement-ME predictor (rutting, fatigue, thermal cracking, IRI, reliability) plus Burmister, IRC, AASHTO, the MEPDG/JPCP distress models and FAARFIELD airfield design; the Advanced FE Suite of in-house finite-element solvers (a genuine 3-D elasto-plastic continuum footing bearing BVP — square/circular/rectangular, 20-node hex, viscoplastic Mohr-Coulomb, with an interactive 3-D settlement-bowl viewer — plus the 2-D footing BVP, transient unsaturated Richards/van-Genuchten seepage, confined + unconfined seepage, strength-reduction slope, concrete slab, bearing); the Deep Foundations Suite — axial t-z/q-w, lateral pile-group p-multipliers, the 6×6 cap stiffness matrix and RC/steel pile sections that replace the separate p-y / group / axial seats firms license; and the Deep Excavation Suite — embedded-wall soil-structure interaction with staged construction, replacing dedicated subgrade-reaction wall packages. The kind of tools firms license separately for thousands a seat. Add or cancel any time.
Implicit RBF surfaces with structural-dip awareness, leave-one-out cross-validation, voxel volumetrics and smooth meshes — built straight from your borehole logs. Rotate the solid, read per-unit volumes, and see exactly where the model is well- or poorly-constrained.
It correlates units across boreholes, flags inconsistencies (outlier contacts, possible pinch-outs), weighs the model's cross-validation error, and drafts a report-ready geological narrative. Advisory by design — you accept, edit, or reject every line, and nothing is auto-signed.
Import legacy logs — including AI-assisted ingestion of scanned and PDF bore logs — and export validated AGS 4 and DIGGS 2.6 for common FE packages and your peers. Open standards in, open standards out: your data is never locked in.
Not a list of buzzwords — every item carries its governing standard and a worked example you can open. Click through the catalogue to see exactly what each one computes.
Legacy per-seat tools often cost $3,000–$5,000/seat/yr. We're positioned at the AI-native, audit-grade end of that range — and we're honest about it.
