AI-Powered Ornamental Metal Takeoffs: Automating Division 05 Estimating

Division 05 miscellaneous metals and ornamental ironwork takeoffs are notoriously difficult to automate. Unlike standard doors, ornamental railing callouts, metal stairs, and custom ironwork symbols vary significantly across architectural plan sets.

A hybrid AI pipeline combines deep object detection models with 360° rotated OCR. The vision model detects custom railing vectors and stair details while the OCR parses linear footage callouts, material specs (stainless, bronze, powder-coated steel), and elevation details.

This approach enables Division 05 estimating teams to produce accurate Bill of Quantities (BoQ) spreadsheets in minutes rather than days.
