Civils.ai Review 2026: QA-Reviewed AI Takeoffs Built for Civil Work

Updated November 3, 2026 – Tested Intelligence

Quick verdict: Civils.ai is a web service that measures civil drawings for you: you type the scope in plain English, the AI measures the PDF, and a person quality-checks the result before it comes back as an annotated PDF and a clean Excel file. That human QA step, plus its geotechnical roots in borehole-log extraction, is what sets it apart from self-service takeoff tools. The catch is the meter: your monthly takeoff allowance is counted per drawing sheet, by scale.

What it is

Civils.ai, founded in 2022, started in geotechnical preconstruction. Trade magazine IRONPROS covered it extracting borehole logs and site investigation data from PDFs into a private map, with exports to Excel and AGS files and simple 3D and 2D section views so engineers can understand ground conditions without retyping thousands of pages.

The product has since widened into quantity takeoffs for groundworks, earthworks, landscaping, utilities and concrete work, plus AI search and checks across specs, contracts and bid documents. Civils.ai says its takeoffs support more than $3bn of projects (vendor figure) and that every takeoff is reviewed by a human before delivery.

Key features

Plain-English takeoff requests: type a scope such as “measure all asphalt paving” and get that measurement, not a generic auto-detection dump
Human QA on every takeoff: results arrive as an annotated PDF plus a clean Excel export, checked before delivery
Civil data extraction: borehole logs from geotechnical reports, reinforcement schedules, subsurface utilities and concrete volumes; earthworks cut-and-fill volumes are listed by the vendor as coming soon
AI search and Q&A across contracts, specs and bid documents, with citations that open the source
Unlimited AI searches and checks on paid plans, under a fair-use, single-user rule
Your documents are never used to train models, per the pricing page

Pricing

Starter is $90 per month for a single user: 10 takeoffs a month, unlimited AI searches and checks, 2 GB of storage and email support. Professional is $270 per month, also single user: 30 takeoffs a month, 50 GB of storage, revisions requested from comments, a system that learns your standards, and priority support. Enterprise is custom-priced, with a custom takeoff allowance, API and MCP integrations, SSO/SAML and a custom data-processing agreement. Starter and Professional are month-to-month and cancel-anytime, with no setup fees.

What the pricing page doesn’t make obvious: a “takeoff” is counted per drawing sheet, based only on the sheet’s scale. A sheet at up to 1:365 counts as 1 takeoff; 1:366 to 1:505 counts as 2; 1:506 to 1:720 counts as 3; and anything above 1:720 counts as 5. So a Starter month’s 10 takeoffs can be gone in two large-scale sheets. The second catch: both self-serve plans are single-user. A second estimator means Enterprise, and multi-step agent workflows beyond standard searches may be priced separately under the fair-use note.

Who it’s for

Civil estimators and consultants who price groundworks, earthworks, utilities and concrete, and geotechnical teams buried in PDF borehole logs and old site investigation reports.

Who should skip it

Building contractors who want unlimited takeoffs they run and check themselves: Togal.AI, reviewed here earlier, charges $299 per user per month billed yearly for unlimited self-service takeoffs with no review step. Skip Civils.ai too if you need several estimators sharing one low-cost plan, or if most of your work is above-ground building takeoff rather than civil scope.

Pros

Every takeoff is human-checked before it lands in your bid
Built for civil scope other takeoff tools skip: boreholes, utilities, rebar, volumes
Published, cancel-anytime pricing with no setup fees
Document search answers cite and open the exact source
Annotated PDF plus Excel is a deliverable you can hand to a client or checker

Cons

Scale-based counting can burn a month’s allowance in a few large sheets
Self-serve plans are single-user only; teams are pushed to custom Enterprise
The QA step is a service, not instant self-service software
Earthworks cut-and-fill volumes are not live yet, per the vendor’s own comparison page
Small company (founded 2022) next to Autodesk- and Trimble-scale rivals

FAQ

How does Civils.ai count a takeoff?

Per drawing sheet, by scale only: up to 1:365 is 1 takeoff, rising to 5 takeoffs for a sheet above 1:720. The company says it notifies you at your allowance, with top-ups or an upgrade as the options.

Is the 97% accuracy claim independent?

No. “Reviewed by humans, 97%+ accuracy on takeoffs” is Civils.ai’s own pricing-page claim. For balance, IRONPROS quoted the COO in 2023 putting extraction accuracy around 80% at that time, weakest on blurred pre-1980 scanned logs. Treat old scans with extra care either way.

Can my team share one Starter account?

No. Unlimited searches are fair use for one person on one account, on both Starter and Professional. Multi-user access is an Enterprise feature.

Bottom line

Civils.ai is the takeoff tool for civil work where a checked number matters more than an instant one, and its borehole and subsurface extraction has no real equivalent in the general takeoff tools we have reviewed. Budget by sheets, not projects, and it is fairly priced. If you measure buildings at volume and trust your own checking, a flat-rate self-service tool fits better.
