Civils.ai
AI quantity takeoffs and checks for contractors, reducing manual effort by up to 90%.
Civils.ai is the most construction-specific takeoff AI we've tested — it reads drawings, measures, and cites sources with human QA oversight. For firms where accuracy is non-negotiable, the premium is justified. But avoid it if you need CAD/BIM integration or work mainly with pre-1975 drawings.

Skip Civils.ai if you need CAD/BIM integration, work primarily with pre-1975 hand-drawn PDFs, or require same-day takeoff turnaround without the 24-hour QA review.
The 5-takeoff-per-sheet cap can force you into higher tiers or custom pricing on complex multi-trade drawings.
Civils.ai's pricing fits mid-sized contractors and consultants who need reliable takeoffs without hiring more staff. At $90/mo for 10 takeoffs, it's competitive with manual estimating costs. Cheaper options like Bluebeam Revu offer CAD-like tools but lack AI automation; more expensive enterprise estimating suites cost thousands per seat.
In short
Civils.ai — AI quantity takeoffs and checks for contractors, reducing manual effort by up to 90%. Best for Contractors needing accurate quantity takeoffs from modern PDF drawings, Groundworks estimators extracting subsurface data from borehole logs, Pre-construction teams running checks across specs and codes. Free to start; paid plans from $90/mo.

About Civils.ai
Civils.ai is a construction-specific AI platform that automates quantity takeoffs and checks for estimators, pre-construction teams, and civil consultants. It measures areas, lengths, volumes, and counts directly from PDF drawings using plain-English prompts, eliminating hours of manual takeoff work. Unlike general LLMs, it's built for AEC: it reads and annotates drawings, extracts complex tabular data, and cites sources, with every output QA-reviewed by an in-house team for 97%+ accuracy on modern PDFs. You get marked-up results you can trust and export to Excel or PDF. Beyond takeoffs, the platform extracts subsurface data from geotechnical reports, digitizing boreholes into AGS 4.1, Excel, and DXF, and supports earthworks and landscaping estimates. It also runs custom checks across drawings, specs, and codes of practice, saving frequent checks as reusable templates, and offers unlimited AI searches and checks under a fair-use policy. It handles scanned, historic, and multi-sheet PDFs, though pre-1975 drawings carry a lower accuracy risk. Trusted by 200+ firms across 8 countries, including MAINER, COSTAIN, MEINHARDT, and PENTA OCEAN, Civils.ai has supported $3bn+ in projects. Pricing starts at $90/month for Starter (10 takeoffs/month) and $270/month for Professional (30 takeoffs/month, priority support), with Enterprise custom-priced for multi-user needs including API and MCP integrations. For construction teams needing accurate, auditable takeoffs without the guesswork of generic chat models, Civils.ai is the purpose-built alternative worth the premium.
Behind the Verdict
Civils.ai stands out because it's built for construction, not adapted to it. The core takeoff workflow — upload PDFs, type plain-English prompts, get measured and annotated results — is straightforward and saves significant time. The human QA step is a real differentiator: you get a 97%+ accuracy claim backed by in-house review, which matters when you're pricing a project. Strengths: The platform handles scanned and historic PDFs, which many tools can't. The groundworks and borehole digitization feature is unique — it turns geotechnical reports into structured AGS 4.1 data, saving hours of manual data entry. The discrepancy check capability is also strong, letting you run custom QA checklists across documents. Pricing is transparent with a free tier, so you can test before committing. Weaknesses: The takeoff cap (1 takeoff = 1 sheet × 1 trade) can be confusing, and the 5-takeoff-per-sheet cap might limit complex projects. Lower tiers limit you to 1 user, so teams need Pro or Enterprise. The 24-hour QA turnaround means no same-day results, and there's no CAD/BIM integration — if you work primarily in Revit or AutoCAD, you'll be disappointed. Where it fits: Mid-sized to large contractors and consultants who need reliable, auditable takeoffs from PDFs and want to reduce manual effort significantly. It's great for groundworks and geotechnical work. Where it doesn't: Small teams with simple takeoff needs (free tools may suffice), firms requiring CAD/BIM integration, or those needing real-time site monitoring. If you need same-day turnarounds, the QA delay could be a bottleneck. Compared to general-purpose AI chatbots, Civils.ai's construction-specific features are worth the premium. But for teams on tight budgets, the free tier and lower tiers offer a way in.

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 50-page PDF drawing set for a groundworks project. You upload the PDFs to Civils.ai, type 'measure all paving and landscaping areas', and the AI measures and annotates the drawings within hours.
Outcome: You get accurate quantities with marked-up PDFs and Excel exports, ready for your cost estimate, saving days of manual work.
You have a stack of scanned borehole logs from a site investigation. You upload them to Civils.ai and use the borehole digitiser to extract the data into AGS 4.1 format.
Outcome: You get structured, machine-readable subsurface data in minutes, improving your analysis and client deliverables.
You need to verify that the latest drawings comply with client specs and building codes. You upload the documents to Civils.ai, type your QA checklist, and run discrepancy checks.
Outcome: The AI flags potential issues and code violations, with cited sources, so you can resolve them before construction.

Models Under the Hood
as of 2026-08-30
Limitations
- Takeoffs are counted per drawing sheet per trade, with a cap of 5 takeoffs per sheet for multi-trade projects—this can be restrictive for complex drawings.
- Integrations are limited to Excel/PDF exports on lower tiers; API and MCP are Enterprise-only.
- Lower-tier plans include few users (1 for Starter), so team-wide deployment may require an Enterprise plan with custom pricing.
- The 24-hour QA turnaround means you can't get same-day takeoffs.
- CAD/BIM integration is not supported.
- Also, 'unlimited' AI searches are subject to a fair use policy (one person, one account) and multi-step agent workflows may be priced separately.
