In practice
A broader trade-category map
- Electrical: room and opening context, measured routes and manually reviewed scope—without automatic cable or accessory takeoff claims.
- Carpentry and joinery: measured openings, room notes and customer-facing work sections.
- Decorating, tiling and flooring: reviewed room measurements and areas where geometry supports them, with the firm controlling waste and price.
- Roofing, general building and renovation: imported plans, multi-room evidence, quote versions and accepted-package handover.
