Specialized Solution
Construction Drawing Analysis
Custom AI engineering to extract quantities, symbols, schedules, and structural specifications from complex construction drawings.
Key Extraction Targets
Electrical Symbols
Plumbing Fixtures
Structural Elements
Division 05 Metalwork
MEP Schedules
General Notes
The Problem
Construction drawings are dense, technical, and non-standardized.
Estimators spend up to 60% of their time manually counting symbols and reading schedules. Legacy OCR fails on noisy construction line drawings and rotated text callouts.
System Workflow
How the AI System Works
01
Layer & Symbol Segmentation
Isolate CAD layers, legend symbols, and annotations using spatial feature detectors.
02
Schedule & Text Parsing
Extract tabular schedules (doors, windows, room finishes) and map line items to plan symbols.
03
ERP & Takeoff Integration
Output structured line-item counts directly into estimating software or custom ERP APIs.
