Automatic delineation of engineering-geological units per GOST 20522
From AGS4 data the tool proposes a breakdown into engineering-geological units: it checks the depth trend, coefficient of variation, and t-test differences, keeps a decision log, and produces an explanatory note in DOCX.

Standards
GOST 20522-2012, the section on delineating engineering-geological units.
Input
An AGS4 file with properties versus depth.
Output
EGU breakdown, decision log, DOCX note.
What it does
- Units derived from the samples with a full decision log
- AGS4 upload, schedules to XLSX and the note to DOCX
- Calculations are stored on the server and reopen next time, company letterhead with signatures

Is it automatic or advisory?
The tool proposes a breakdown and justifies it; the final decision stays with the engineer.
On what criteria are samples merged?
Absence of a depth trend, an acceptable coefficient of variation, and t-test comparison of means.
