AI Reduces Geotechnical Document Analysis from 3 Weeks to 3 Hours

A US-based geotechnical company implemented an AI document-processing system to automate analysis of multi-page PDFs containing borehole logs, tables, diagrams and soil-layer drawings. The solution used LLMs and VLMs to identify document structure, separate borehole logs, extract soil-layer data, store structured results in a database and generate client-formatted Excel spreadsheets. A proof of concept tested the models on real client data against expert-prepared evaluation sets. Document analysis time fell from about three weeks to around three hours, while quality was reported as comparable to human experts.
