You can, and for a first look it does well. We tested it on four public bid sets — a post-frame addition, a renovation addendum, a six-trade senior center and a wastewater project, 6 to 56 drawing sheets — giving a chat AI the same PDFs our system read, byte for byte, and running three of the four on the same AI model our system reads drawings with. It listed 46 to 121 items in 2 to 23 minutes, and most of its main counts and areas (slab concrete, light fixtures, diffusers, floor drains) landed within about 5%. It also caught two things our system got wrong, pier excavation and lintels over openings, and both are now in our checks.
What a contractor runs into when they do it themselves, each seen in that test:
- Wrong where it is surest. On one set it swapped the building’s axes: 11 trusses spanning 36′ instead of 9 spanning 47′-6″, marked high confidence.
- Counts by eye run over. About 25 corner guards where the plans show 14; about 22 hose reels for 17.
- A number where the drawings give none. 38,000 SF of partitions with the wall-type sheet not in the set.
- Big sets read in part. On an 84-page set it skipped 15 pages, the general notes and the first sheet of each trade among them.
- Whole groups left out. 38 interior windows were not in its list at all.
- Nothing to check back. The answer is text: no calculation table, no marked-up page, no sheet reference. The only way to check it is to measure again.
Scored only where an independent judge could settle it — the engineer’s bid quantities, tag counts read from the PDF text, and the drawings themselves — our system had 26 right, 6 wrong and 0 invented; the chat AI had 23 right, 9 wrong and 1 invented. Seventeen of those right answers were the same on both sides, so the gap is in the rest. Four lines where the two gave the same figure but no judge could settle it — wall cladding, one slab, the light fixtures and the diffusers — are left out of the score. The difference is less the reading than what comes with it: its wrong answers look like its right ones, while every line we deliver is traced to its sheet with its calculation and marked where it was measured, so you can tell them apart.
