A general contractor uses AI drawing comparison to catch design changes before they get priced

Construction Dive reported on 5 August 2026 that Novo Construction, a Menlo Park general contractor, is using BuildCheck's Diffs product to flag inconsistencies between drawing versions automatically — work previously done by overlaying hundreds of pages by hand in tools such as Bluebeam. The practical use is early pricing: when a wall, window or door moves between revisions, the tool surfaces the scope change in time to reach the contractor's number. Chief information officer Colin Stoner described the working posture as 'trust but verify' — staff review each flag and dismiss the ones that do not apply. No time or cost saving was quantified in the piece.

What it means A narrow, checkable task — diff two document sets and show a human what moved — is where AI is currently earning its place in a trade that prices mistakes in six figures. Note the operator quantified nothing.
