Drawer AI
What it is
Drawer AI is takeoff and estimating software built specifically for electrical contractors. Working from PDF drawings, it detects power devices and lighting fixtures, reads panel schedules, routes branch circuits with automated wire sizing and voltage-drop calculations, and stitches multi-page drawings into one layout, then exports an Excel report and a marked-up PDF for review. The company also offers AI-generated Revit models and a concierge takeoff service.

Use cases with Drawer AI (2)
Use AI as the first pass on electrical takeoffs
Intermountain Electric
Intermountain Electric's estimators run drawings through AI for first-pass lighting, power and receptacle counts, branch routing, panel and lighting schedules, and drawing stitching, then review and correct it before anything goes into the estimating system. The case study says one high-volume takeoff that used to take several 15-hour days was done in a few hours, and that the AI gets branch measurements about 95% of the way before human QA.
Bid more work without hiring another estimator
WTC Electric
Family-owned WTC Electric in Charlotte, NC faced rising bid volume, driven partly by data-center demand, and couldn't find another estimator. It moved takeoffs to AI device detection and automated branch routing, with the vendor's human concierge team handling peaks and poor-quality drawing sets. Drawer AI reports a 70% reduction in takeoff time on large projects and device detection accuracy above 95%.
