What an AI has to get right
- Rough carpentry by assembly. Blocking, sheathing and backing follow the wall and roof assemblies they belong to.
- Casework and millwork by count and length. Base and upper cabinets, countertops and shelving are usually on interior elevations.
- Trim by the linear foot. Base, casing and chair rail run around rooms and openings.
Where AI takeoffs go wrong
Carpentry lines are spread across wall sections, elevations and schedules. A tool that only reads floor plans under-counts casework and misses sheathing and blocking called out in assemblies.
How Field24 handles it
Field24 reads the assemblies and elevations along with the plans, measures each run from the drawing and ties every row to its mark on the sheet.
