Vawn started as a handful of detections. This summer it became a complete take-off you can drive from the first sheet to the last: fire alarm counted automatically, take-off mode on every sheet, the whole electrical system in one view, Constructability review, multifamily unit types, and an API.
The quarter Vawn stopped being a symbol counter: switchgear as a real takeoff with its own export, panel and feeder schedules you can browse, gear read off the one-line, BOM exports by trade, and branch circuits you can trace from the panel.
Explanations for the 85% spike in electrical equipment prices felt shallow, so we traced the money from Chilean copper mines to manufacturer margins. Here is the data-backed reality of what is actually driving costs and contract risks.
After processing real electrical blueprint sets from hospitals, schools, correctional facilities, and international projects, we learned that no two drawing sets look the same, and why that matters for automated takeoff.
Why subcontractors are becoming engineering firms: declining design quality forces multiple estimates per project, BIM upgrades from Level 300 to 400, and manual verification. Shadow work that kills productivity.
Analysis of U.S. construction data reveals 54% of residential firms have under 5 employees, 7-11% annual firm churn, and declining efficiency as companies scale, exposing fragmentation challenges in the trades.
