"We can now generate detailed material takeoffs in a fraction of the time it previously took. We progress Whole Life Carbon Assessments more efficiently without compromising accuracy."

Dom W., Associate Director · June 2026

"Their AI's ability to digitize vast amounts of subsurface data has significantly improved our efficiency — leading to better quality of submissions and impressed our clients."

Omid K., Principal Engineer · May 2026

"This has massively sped up our preliminary estimates. The accuracy is impressive. My only wish is a faster turnaround; waiting up to 24 hours for the reviewed takeoffs can be a bottleneck on fast-moving bids."

James P., Estimator · April 2026

"The ability to transcribe data from borehole logs and reports, no matter how old, has been a great time saver. We've also been pleased with the collaborative approach to enhancing features."

Who It's For

Why Construction & Civil Engineering Excellence choose this tool

🎯
Built for
Best for automating time-consuming quantity takeoffs from PDF drawings and cross-referencing technical specifications for pre-construction teams.
In-Depth Overview
Civils.ai delivers a direct solution to one of the most time-consuming tasks in pre-construction: quantity takeoffs. Instead of relying on generic AI, it uses specialized agents trained specifically to read and measure construction drawings, achieving a claimed 97% accuracy on modern PDFs. This is a significant advantage, as general models struggle with the complexity of drawings, tabular data, and industry-specific notations. The platform's core promise is to increase your team's capacity without increasing headcount. It backs this with proof points like reducing manual effort by up to 90% and supporting over $3 billion in projects for more than 200 firms. A key differentiator is its human-in-the-loop quality assurance. Every AI-generated takeoff is reviewed by a human QA team before you receive it, providing a layer of confidence that fully automated systems lack. This allows estimators to trust the output for bids and project planning. It also handles complex subsurface data from geotechnical reports, a specialized capability that saves engineers significant manual transcription time.

Key Use Cases

🏗️
Slash Takeoff Time by 90%
Estimator

Run checks across your entire document set—drawings, specs, contracts, and codes. Create reusable templates for frequent checks to ensure consistency.
528+ hours saved annually (per case study)
✓ Pros
Purpose-built for construction, unlike general-purpose AI.
Achieves over 97% accuracy on modern PDFs, verified by a QA team.
Reduces manual takeoff and checking effort by up to 90%.
Handles complex documents like geotech reports and scanned drawings.
Transparent, takeoff-based pricing with no setup fees or lock-in.
· Cons
QA-reviewed results take up to 24 hours, which is not instantaneous.
Starter and Professional plans have monthly takeoff limits.
Accuracy is not guaranteed for hand-drawn or very old (pre-1975) PDFs.
Advanced multi-step AI agent workflows may incur extra custom costs.
⚡ Editorial Verdict

Civils.ai is a powerful, specialized tool that delivers highly accurate, human-verified takeoffs—a critical feature general AI can't match. Its focus on groundworks and subsurface data is a key differentiator for civil projects. The main trade-off is speed; while it saves hours of manual work, the human-in-the-loop review means results are returned within 24 hours, not instantly.

Questions & Answers

Frequently asked questions

What types of takeoff does Civils.ai support? +
Civils.ai supports a growing range of takeoffs, including measuring areas, lengths, volumes, and counts for trades like groundworks, landscaping, utilities, and concrete, all from PDF drawings.
How is data security and ownership handled? +
You retain full ownership of all data you upload. It is used only to process your requests and is never used to train third-party models. Data is encrypted in transit and at rest, and you can delete your data at any time.
Where does Civils.ai store my project data? +
Your data is stored securely on servers located in the United States, managed by a vetted, enterprise-grade cloud infrastructure provider. All documents are anonymized and isolated to your specific account.
How accurate are the AI takeoffs? +
Civils.ai achieves over 97% accuracy for takeoffs from modern PDF drawings. This is ensured through a human-in-the-loop process where a QA team reviews all AI-extracted data. Accuracy on older, hand-drawn PDFs (pre-1975) is not guaranteed to be as high.
How are takeoffs counted in the pricing plans? +
One takeoff is defined as a single trade measured on a single drawing sheet (e.g., landscaping areas on one sheet). Measuring two trades on the same sheet counts as two takeoffs. Charges are capped at a maximum of 5 takeoffs per drawing sheet.
How long does it take to get results? +
Due to the human quality assurance process, the platform aims to return verified results within 24 hours. You will be notified by email once the process is complete.
