Automate Drawing Review & Material Takeoff for Fabricators
Three agents handle shop drawing reviews, material takeoffs, and welder certification tracking — reducing errors by 80% and saving 35 hours weekly.
AI Readiness Score
Structured data in sheets, standardized drawing formats
Already using Claude, semi-technical team with manufacturing focus
Budget range supports comprehensive agent deployment
Clear repetitive processes in drawing review and material takeoffs with defined quality standards
3-6 month timeline reasonable for phased implementation
Good API coverage but AutoCAD integration complexity moderate
How This System Works
Architecture
Three-agent system focused on fabrication workflow optimization: drawing review automation, material takeoff accuracy, and compliance tracking. Integrates existing AutoCAD and Google Sheets workflow with enhanced Claude analysis capabilities.
Data Flow
Drawings flow from AutoCAD through automated review and material extraction, with results stored in Google Sheets. Certification data maintained in sheets with automated monitoring. All agents communicate status and alerts through Slack for seamless team coordination.
Implementation Phases
Setup APIs, databases, and initial data structures
Deploy takeoff automation for immediate waste reduction
Automate certification tracking and notifications
Deploy complex drawing review automation
