Geotechnical engineering software
Geotechnical engineering software for data you can defend.
G& carries every borehole, sample and laboratory result from the rig to a certified AGS 4.1 submission — logged to ISO 14688 / 14689 and BS 5930, tested to BS 1377 and ASTM methods, validated at every step and accepted by a named engineer.

What the software does
One controlled line from field capture to signed deliverable, with the standards encoded in the software rather than in the reviewer's memory.
C01
Borehole and trial pit logging
Field records captured against ISO 14688 / 14689 and BS 5930 description rules: strata, samples, groundwater, in-situ tests, with depth logic enforced as you type.
C02
Laboratory data management
Classification, strength and consolidation tests tracked through their lifecycle to BS 1377 and ASTM methods, each result bound to a resolvable sample reference.
C03
Automated validation
Four layers — data integrity, engineering logic, AGS 4.1 compliance and plausibility — run on entry. Contradictions are quarantined, never imported on trust.
C04
AGS 4.1 submission control
Groups, headings and units checked against the schema before export, so a submission is right the first time it reaches the client's data checker.
C05
Logs, tables and reporting
Production borehole logs, factual report tables and plots generated from approved records only, so drawings and data never diverge.
C06
Handwriting OCR intake
Scanned field and lab sheets transcribed into structured records — including SPT blow counts per increment — and validated in the same pass.
How G& differs from general geotechnical software
Built for submissions, not spreadsheets
Most geotechnical software stores data. G& governs it: every value carries its source, standard version and the engineer who accepted it.
Standards-aware by default
AGS 4.1, ISO 14688 / 14689, BS 5930, BS 1377, ASTM D1586 / D2487 and Eurocode 7 conventions are encoded in the validation rules, not left to reviewer memory.
Legacy archives welcome
Historic desktop archives, Excel workbooks and previously exported AGS files migrate under the same validation as live data, with provenance retained.
Priced to be adopted
Platform bands plus per-discipline seats, with free viewer access so reviewers and clients can read data without buying a licence.

Geotechnical software questions
+What is geotechnical engineering software?
Software that captures, validates, stores and reports subsurface investigation data — borehole and trial pit logs, in-situ tests, laboratory results and groundwater observations — and produces the deliverables a ground investigation is judged on, typically borehole logs, factual report tables and an AGS data submission.
+Which standards does G& support?
AGS 4.1 for data exchange, ISO 14688 and ISO 14689 plus BS 5930 for soil and rock description, BS 1377 and ASTM methods for laboratory testing, ASTM D1586 and BS EN ISO 22476-3 for SPT, ASTM D2487 for classification, and Eurocode 7 conventions for derived parameters.
+Can it replace our existing geotechnical logging software?
Yes. Legacy projects, templates and log layouts are migrated and rebuilt as output templates, and both systems can run in parallel while the archive is transferred, so no live works are interrupted.
+Does it handle laboratory data as well as field data?
Laboratory testing runs as its own governed lifecycle — scheduling, assignment, result entry, checking and approval — bound back to the sample it came from, so field and lab data stay reconciled.
+Who uses it on a project?
Site engineers and loggers capture field data, laboratory staff enter test results, a lead geotechnical engineer validates and accepts records, and consultants or owners review approved data and submissions through free viewer access.
+Is it cloud-based?
Yes. Data is held in one central project database accessible to the whole delivery chain, with role-based permissions and a full audit trail against every value.
