CASE STUDY: Subterra GeoIQ

AI-Powered Geotechnical Bore Report Intelligence Platform

Executive Summary

Subterra GeoIQ is an advanced AI platform that redefines how geotechnical engineers analyze, compare, and visualize subsurface data. Built specifically for the geotechnical industry, GeoIQ converts static boring logs and supplemental files into fully interactive, searchable, geospatial datasets with 3D visualization and predictive capabilities.

GeoIQ eliminates manual data transcription, increases engineering accuracy, and gives project teams immediate access to insights that traditionally require hours of tedious report review.

PROJECT BACKGROUND

Geotechnical investigations rely on bore logs, SPT blow counts, Atterberg limits, water table readings, and laboratory test results—almost always delivered as static PDFs. Engineers must manually review each page, transcribe data into spreadsheets, and compare bores across multiple locations.

This creates several problems:

• Time-consuming data extraction

• Human error during transcription

• Difficulty comparing bores between reports

• Fragmented datasets spread across PDFs, Excel sheets, CPT files, and lab documents

• No way to generate predictive subsurface models without drilling

Subterra GeoIQ solves all of this in one unified system.

SOLUTION OVERVIEW

What Subterra GeoIQ Is

GeoIQ is an AI-driven bore report intelligence system that ingests PDFs and supplemental files, extracts structured soil data, enables natural-language querying, and visualizes subsurface conditions in 2D, 3D, and cross-section formats.

The platform supports both engineering workflows and project management needs with a fast, intuitive, and geospatially aware interface.

CORE CAPABILITIES

1. Automated PDF Processing

GeoIQ automatically extracts geotechnical data from PDF boring logs, including:

• Borehole identifiers and coordinates

• Soil layers with depth ranges and USCS classifications

• SPT N-values and blow counts

• Water table elevations

• Physical properties such as moisture content, density, and Atterberg limits

• Grain size distributions

• Full support for multi-bore, multi-page reports

This removes the need for manual transcription and drastically accelerates data preparation for engineering analysis.

2. AI-Powered Question & Answer (RAG)

Engineers can interact with subsurface data using natural language:

• “What is the N-value at 15 ft in B-3?”

• “Which bores encountered clay below the water table?”

• “Compare the soil layers between B-1 and B-5.”

GeoIQ searches across all PDFs and supplemental files (Excel, CPT, CSV, additional reports), returning answers with page-level citations so the engineer can instantly verify the source.

This makes complex geotechnical queries effortless and fully traceable.

3. AI Bore Prediction

GeoIQ introduces predictive subsurface modeling:

• Drop a pin anywhere on the map

• Platform analyzes nearby bore data

• Generates predicted soil layers with depth ranges, USCS classifications, confidence scores, and reasoning

This is invaluable for planning drilling programs, anticipating site challenges, and estimating soil behavior before mobilization.

4. Interactive Mapping

GeoIQ consolidates all bore locations into an interactive, multi-layered map:

• Global map view of all projects

• Project-level workspaces

• Lasso selection for multi-bore operations

• Clustering for large datasets

• Satellite, street, and hybrid basemaps

• Hover previews and click-to-select details

• Color schemes for soil types, depth, water table elevation, and more

This transforms static boring logs into fully geospatial intelligence.

5. 3D Visualization

Engineers can finally see the subsurface:

• 2D bore markers and summaries

• Full 3D bore columns

• Fence diagrams and cross-sections

• Subsurface 3D soil models interpolated between bores

• Water table surfaces

• Color-coded soil layers based on USCS classifications

• Adjustable vertical exaggeration

This creates clarity in situations where 2D tables fall short.

6. Hierarchical Navigation

GeoIQ provides a powerful file-navigation system:

• Projects → Reports → Bores

• Global search across the entire hierarchy

• Fast virtualized rendering for large organizations

• Keyboard shortcuts for power users

• Cross-project bore selection for comparison

This delivers enterprise-scale organization with intuitive usability.

7. Multi-File Support

In addition to PDF boring logs, GeoIQ supports:

• CPT data

• Excel calculations (.xls/.xlsx)

• Laboratory reports

• Supplemental documentation and engineering addendums

• Multiple PDFs under a single project

All files are indexed together and made available for unified AI querying.

Excel data can automatically merge with PDF extractions to enhance bore records with additional lab test information.

8. Bore Comparison

Engineers can compare up to five bores at once:

• Aligned depth profiles

• Soil layers and classifications

• SPT and N-value differences

• Cross-project comparison capability

• Exportable comparison views for reports

This is extremely useful during foundation recommendations, QA checks, and report writing.
