Civils.ai
AI quantity takeoffs from construction PDFs — measured, QA-reviewed and cited back to the source drawing.
If your estimating bottleneck is measuring quantities off construction PDFs and proving where each figure came from, this is aimed squarely at you — human QA on every measurement plus marked-up source documents is the part general-purpose AI can't match. Do the arithmetic on takeoff allowances before you buy: at one takeoff per sheet up to 1:365, the 10 on Starter run out fast on a multi-sheet package. And if your drawings are hand-drawn or pre-1975, the accuracy guarantee doesn't hold.

Skip Civils.ai if you need quantities to round-trip into CAD or BIM, or if your drawing set is largely hand-drawn or pre-1975 — the vendor states accuracy isn't guaranteed there, and the tool stops at PDFs.
A takeoff is one trade on one drawing sheet at up to 1:250 scale, so measuring the same trade across three sheets burns three takeoffs instead of one.
At $90/mo billed monthly (Starter, single user, 10 takeoffs) and $270/mo billed monthly (Professional, single user, 30 takeoffs), Civils.ai sits above generic AI assistants and free takeoff calculators, and below full estimating suites and enterprise AEC platforms that bundle CAD/BIM. It is cheapest for solo estimators and small groundworks teams whose work fits in 10–30 takeoffs a month; multi-user teams need Enterprise custom pricing with volume and annual contract terms.
In short
Civils.ai — AI quantity takeoffs from construction PDFs — measured, QA-reviewed and cited back to the source drawing. Best for Estimators measuring areas, lengths and counts from modern construction PDFs who need source-cited quantities, Groundworks and geotechnical teams converting PDF borehole logs into structured AGS 4.1 data, Pre-construction teams running QA and compliance checks across drawings, specs and contracts. Plans from $90/mo.

7 mentions across 2 sources (YouTube, Product Hunt), 10 more we could not attribute · researched Oct 8, 2026.
Weighted by the 17 posts each of 2 sources contributed.
- +Plain-English takeoff prompts — estimators confirm this speeds the first pass significantly
- +Human QA review on every measurement matches what experienced QSs say they need
- +Handles scanned, historic and multi-sheet PDFs, not just clean vector drawings
- +Annotated drawings with cited sources let you trace every quantity back
- +Excel export fits straight into existing estimating spreadsheets without friction
- −Almost zero independent reviews — Reddit, HN and Trustpilot all came back empty
- −Product Hunt launch drew only 8 upvotes, suggesting weak organic community pull
- −No CAD or BIM integration forces parallel PDF workflows for Revit and Civil 3D teams
- −Pre-1975 and hand-drawn drawings fall below the advertised 97%+ accuracy line
- −Prompting skill required — juniors in the comments couldn't even follow the demo
- • Project-plan and Enterprise pricing tiers are not publicly listed — quotes required
- • Human QA on every measurement is bundled into price, which tends to raise per-seat cost vs pure-software tools
- • One-time $190 Community tier is separate from project plans, so individuals still need a plan to run real takeoffs

About Civils.ai
Civils.ai is an AI quantity takeoff and drawing-check platform for construction estimating teams. You drop in PDF drawings — scanned, handwritten, historic or multi-sheet all accepted — pick an AI Agent and type the scope in plain English ("measure all paving and landscaping material areas shown in legend"). It returns annotated, marked-up drawings plus Excel and PDF exports, with the source documents cited so you can open and verify any number yourself. The second half of the product is checking. Civils.ai runs an automated review across drawings and documents and sorts findings into Critical, High risk, Medium risk and Low risk issues. It cross-checks sheets against one another — civil versus landscape, architectural versus structural — and lets you fine-tune checks and save repeats as templates. Groundworks, landscaping, utilities, concrete and geotechnical scopes are covered, and a borehole digitiser turns PDF geotechnical reports into structured AGS 4.1 data with Excel and DXF output. Every AI-extracted measurement passes through human-in-the-loop QA, which is where the vendor's 97%+ accuracy claim for modern PDFs comes from. Civils.ai claims up to 90% less manual effort and cites 200+ firms across eight countries and $3bn+ of supported projects. Processing is asynchronous: close the tab, get an email when extraction finishes, results targeted inside 24 hours. Takeoffs are consumed per sheet and weighted by scale — one up to 1:365, rising to five per sheet above 1:720. Pricing runs Starter at $90/month (single user, 10 takeoffs), Professional at $270/month (30 takeoffs, priority support, revision requests) and Enterprise custom for multi-user and volume work, plus a one-off $190 Community tier. It is priced for working estimating teams. Against general-purpose AI, the difference is measuring a drawing and citing it rather than reading its text.
Behind the Verdict
Where Civils.ai earns its keep is the audit trail. Every quantity lands on a marked-up drawing with the source sheet cited, so a reviewer can trace a number back in seconds instead of re-measuring it. We'd reach for it when a QS or estimator is spending days scaling and counting by hand, and when someone downstream needs to sign off on the result. The buyer question is allowance, not capability. Takeoffs are charged per drawing sheet and scaled: one up to 1:365, two to 1:505, three to 1:720 and five above that. A dense site plan package will chew through Starter's 10 in a morning. Run your own sheet counts and scales through that table before choosing a tier — Professional's 30 is where most active estimating teams will actually sit, and it adds revision requests from comments. Pick it when the work is groundworks, landscaping, utilities, concrete or geotechnical and the inputs are PDFs. The borehole digitiser is the sharpest narrow use case in the product: PDF geotech reports in, AGS 4.1, Excel and DXF out, and Costain and Meinardt both cite the subsurface transcription in the vendor's own testimonials. That's a job almost nobody enjoys doing manually. Pass if your workflow depends on CAD or BIM round-tripping — this is a PDF-in, quantities-out tool. Pass too if you expect in-app collaboration on Starter or Professional; both are single-user. Enterprise is where API, MCP, SSO, SAML and custom volume sit. The closest alternative is doing it manually in Bluebeam or a takeoff package, or feeding drawings to a general model and hoping. Neither gives you the QA pass or the citation. Watch the 24-hour turnaround on complex extractions — it's asynchronous by design, not a live session.

Real-world workflow fit
Concrete scenarios for the personas Civils.ai actually fits — and what changes day-one when you adopt it.
You receive a multi-sheet paving and drainage drawing pack as PDF. You drag the sheets into Civils.ai, select Extract CAD data, choose an AI Agent and type "measure all paving and landscaping material areas shown in legend", then hit Run.
Outcome: The agent returns an annotated drawing with marked-up measurements. Civils.ai's QA team reviews the measurements before you download them to Excel, so your priced takeoff carries a 97%+ accuracy claim on modern PDFs with cited sources.
You have a stack of PDF geotechnical reports from an old site investigation. You upload them and run the borehole digitiser to convert the logs into structured AGS 4.1 data, then export to Excel and DXF for the earthworks model.
Outcome: The logs become machine-readable data instead of manual entry, which is the workflow Meinhardt described as "a great time saver" for transcribing borehole data "no matter how old" the reports.
Before submission you type your QA checklist into Civils.ai and let it run the checks across the drawings, Division 1 specifications and the contract, saving the check as a reusable template for the next bid.
Outcome: Discrepancies and code-compliance issues are flagged across the document set in minutes rather than by manual cross-reading, and the same template reruns on the next project without retyping the checklist.

- Run contract compliance checks against specifications and codes
- Cross-check schedules of rates against variation orders
- Measure earthwork volumes for landscaping and utility projects
- Digitise historical scanned drawings for legacy project analysis
- Review Division 1 specs as an estimator to catch missed scope before submission
- Speed up Whole Life Carbon Assessment material takeoffs
Models Under the Hood
as of 2026-10-15
Limitations
- Takeoffs are counted per drawing sheet based on the sheet's scale: up to 1:365 is 1 takeoff, 1:366 to 1:505 is 2, 1:506 to 1:720 is 3, and above 1:720 is 5.
- Starter offers 10 takeoffs/month and Professional 30 takeoffs/month, both single-user, so multi-sheet packages consume allowance quickly. "Unlimited AI searches & checks" is under fair use (one person, one account), and multi-step agent workflows beyond standard searches may be priced separately on a custom basis.
- API/MCP integrations plus SSO/SAML are available on the Enterprise tier only.

Where the pricing makes sense
The company stage and team size where Civils.ai's pricing actually pencils out — and where peers do it cheaper.
At $90/mo billed monthly (Starter, single user, 10 takeoffs) and $270/mo billed monthly (Professional, single user, 30 takeoffs), Civils.ai sits above generic AI assistants and free takeoff calculators, and below full estimating suites and enterprise AEC platforms that bundle CAD/BIM. It is cheapest for solo estimators and small groundworks teams whose work fits in 10–30 takeoffs a month; multi-user teams need Enterprise custom pricing with volume and annual contract terms.
Setup time & first value
How long it actually takes to get something useful out of Civils.ai — broken out by persona, not the marketing-page minute.
For a single estimator on Starter, expect to be running a first takeoff within an hour: create an account, upload a PDF drawing, select Extract CAD data, pick an AI Agent and type the scope. Professional adds revision requests and priority support but the same core flow. Enterprise adds SSO/SAML, API and MCP integrations, and a custom DPA, so allow procurement and security review time before
Switching to or from Civils.ai
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual PDF takeoff and scale-and-count: upload the same drawing PDFs, type the scope you'd otherwise measure by hand, and export to Excel in the same format your estimate already uses
- →From spreadsheet-based estimating: keep your existing Excel workbook and paste Civils.ai's exported quantities into it, so your pricing logic stays intact
- →From a general-purpose AI assistant: move document Q&A and check runs into Civils.ai, which marks up and cites original documents rather than returning text-only answers
- →From manual borehole log transcription: run the geotechnical PDFs through the borehole digitiser to produce AGS 4.1 rather than keying log data by hand
- →From in-house QA checklists: retype each recurring check once as a reusable template, then rerun it across future drawing and spec sets
- ↗To a spreadsheet-only workflow: export all quantities to Excel and annotated PDF before cancelling, since Starter and Professional are month-to-month and you keep access until the end of your billing period
- ↗To a CAD or BIM-native estimating suite: re-key measured quantities into the model-based tool, as Civils.ai does not round-trip to CAD or BIM
- ↗To a general-purpose AI assistant: carry over your Excel exports and annotated PDFs as the source of record, since a text model won't reproduce the drawn measurements
- ↗To an enterprise estimating platform: use Enterprise-tier API and MCP access to pipe Civils.ai outputs into the wider system rather than exporting files manually
