AI earthwork takeoff for small excavation contractors

Two things changed at once. Vision models got good enough to read a grading plan — contour lines, spot elevations, boundary limits — off a flat PDF, which was the blocking technical problem for a decade. And the AI takeoff category that grew up around that capability aimed almost all of it at buildings, because architectural plans are more uniform and the general-contractor buyer is easier to reach. Autocomplete now surfaces 'earthwork takeoff ai' and 'best construction takeoff ai' as real queries, which means the searcher already believes this should exist. They just cannot find it: page one for 'earthwork takeoff software' is a Reddit thread, AGTEK, and a handful of outsourced-service pages. That gap closes the moment one of the funded building-takeoff companies decides sitework is worth a sprint — which is a matter of quarters, not years.

Market gap

The market splits cleanly and leaves one segment stranded. At the top, purpose-built earthwork software: SelectHub lists AGTEK from $20,000 a year, and InSite Elevation Pro publishes no price at all — the site offers a demo booking and a phone number. In the middle, general takeoff tools that measure flat plans but do not model surfaces: PlanSwift Professional at $2,000 a year, STACK Takeoff & Estimate at $249 per user per month. The new AI entrants sit alongside them and aim at buildings: Togal.AI Growth is $299 per user per month billed yearly, Kreo runs $35 to $175 per user per month, and Beam AI covers earthwork but sells a 24-to-72-hour QA-checked service behind a demo request, not self-serve software. Below all of it is the outsourced tier that reveals the real demand: Earthwork Takeoff Services charges from $300 for an on-demand takeoff with a two-to-five-day turnaround and from $2,000 a month for up to six small projects. A small excavation contractor bidding four jobs a month is paying that outsourcer more than $1,000, waiting days for each answer, and has no self-serve product priced for them anywhere on page one.

Week 1-4: the core loop, nothing else. PDF in, contour and spot-elevation extraction, triangulated existing and proposed surfaces, volume differencing out. Build a validation set of 20 closed jobs with known as-built quantities before writing any UI — accuracy is the entire product and you need a number you can publish. Week 5-8: the confirmation UI, because full automation is the wrong bet here: the contractor draws the limit of disturbance and confirms the datum, the model does everything after that. Add the one-page bid summary and the cut/fill color map. Week 9-10: Stripe at $79/mo, free first takeoff as the acquisition engine, and publish the accuracy study — 'we ran 20 closed jobs, here is how close we got' is the only marketing asset that matters to this buyer. Week 11+: r/estimators and r/Excavation, where the questions are already being asked weekly and no vendor is answering them well; then Facebook excavation-contractor groups and equipment-dealer partnerships. Month 4-6: undercut and phasing for Pro, then machine-control export, which is the feature that lets you charge $199 and start taking AGTEK's smaller accounts.
