About
Drawer AI is a specialized AI platform built for electrical subcontractors to dramatically accelerate preconstruction workflows. By leveraging computer vision and proprietary AI, Drawer AI reads PDF construction drawings and automatically counts lighting fixtures, power devices, and other electrical components — tasks that traditionally take hours of manual work. Its Automated Branch Routing engine tests thousands of routing options to determine the most efficient conduit paths, complete with automated wire sizing and voltage drop calculations. The Automated Stitching feature seamlessly merges multiple plan sheets into a unified floor layout, ensuring accuracy and consistency across complex projects. Drawer AI also includes a BIM Wizard that converts PDF drawings into Revit-ready models, bridging the gap between 2D plans and modern BIM workflows. The web-based platform supports Fire Alarm, Telecom, and Security systems in addition to standard electrical work. With a simple drag-and-drop interface, teams can go from raw PDFs to detailed, accurate takeoffs in minutes rather than hours. Drawer AI is purpose-built for electrical contractors looking to win more bids, reduce estimating labor, and improve project accuracy — making it an essential tool for modern electrical preconstruction teams.
Key Features
- AI-Powered Fixture & Device Takeoff: Automatically counts lighting fixtures, power devices, and electrical components from PDF drawings with automated tag linking for features, panels, and circuits.
- Automated Branch Routing: AI engine tests thousands of routing paths to determine maximum efficiency, including automated wire sizing with voltage drop calculations — delivering detailed routing in minutes.
- Automated Plan Stitching: Seamlessly merges multiple split plan sheets into a single, unified floor layout to ensure accuracy and consistency across large or complex projects.
- BIM Wizard (PDF to Revit): Converts 2D PDF construction drawings into Revit-compatible BIM models, bridging the gap between traditional plans and modern Building Information Modeling workflows.
- Multi-System Support: Handles electrical, Fire Alarm, Telecom, and Security system takeoffs from the same web-based platform.
Use Cases
- Electrical estimators using Drawer AI to automate fixture and device counting from PDF bid documents, reducing takeoff time from hours to minutes.
- Electrical subcontractors generating detailed conduit routing plans with voltage drop calculations to improve bid accuracy and project planning.
- Preconstruction teams merging multi-sheet PDF drawings into a unified floor plan layout before starting takeoff or routing work.
- BIM coordinators converting 2D PDF electrical drawings into Revit models to meet owner or GC requirements for BIM deliverables.
- Electrical contractors handling Fire Alarm, Telecom, and Security system takeoffs alongside standard electrical work within a single unified platform.
Pros
- Massive Time Savings: Reduces takeoff time by up to 70%, converting hours of manual counting and routing into minutes of automated processing.
- Trusted by Industry Leaders: Used by 140+ leading electrical subcontractors across the USA, demonstrating proven reliability and real-world adoption at scale.
- End-to-End Preconstruction Workflow: Covers the full preconstruction workflow from PDF upload through takeoff, routing, stitching, and BIM generation in one platform.
- No-Code, Web-Based Interface: Simple drag-and-drop PDF upload requires no technical expertise, making advanced AI accessible to estimators without a software background.
Cons
- Niche Industry Focus: Purpose-built for electrical subcontractors only — not applicable to general construction, plumbing, HVAC, or other trades.
- Paid-Only Access: No publicly advertised free tier; electrical contractors must purchase a subscription to access the platform.
- PDF-Dependent Workflow: Requires drawings to be in PDF format; unusual or non-standard plan layouts may affect AI recognition accuracy.
