Best AI for concrete and masonry takeoff

What an AI has to get right

• Volumes, not just areas. A slab is square feet on the plan but cubic yards on the order; the thickness lives in a section or a general note.
• Everything under the slab. Footings, grade beams, piers, sand or gravel beds and vapor barrier are drawn on the foundation plan and in details, not on the floor plan.
• Reinforcing and accessories. Bars, mesh and ties follow the element they sit in.
• Masonry by the wall. Block and brick are counted from wall length and height, less openings.

Where AI takeoffs go wrong

General assistants tend to take the slab off the floor plan and stop there. Footings and piers drawn only on structural sheets go missing, thicknesses get assumed instead of read, and masonry walls are measured without subtracting doors and windows.

How Field24 handles it

Field24 measures from the drawing's own geometry (exact lengths from the PDF's vector layer, a detector for scanned sheets) and marks every row on the sheet it came from, so you can check a footing run or a slab area in seconds. Pricing follows from the same rows.
