Civils.ai is a web-based AI tool for civil and construction teams. It measures areas, lengths and counts from PDF drawings for quantity takeoff, with Excel and annotated PDF outputs, and runs automated checks across drawing sets that flag issues by risk level. Estimators and engineers must check every quantity and flag.

## What is Civils.ai?

Civils.ai is a web-based AI tool for civil engineering and construction, made by a company based in Singapore. It measures quantities from PDF drawings, runs automated checks across drawing sets, and digitises geotechnical records. Enterprise plans add API access and single sign-on.

## How do engineers and estimators use Civils.ai?

- **Takeoff** of areas, lengths and counts for BOQs and estimates
- **Drawing reviews** before issue or tender, with issues flagged by risk
- **Consistent checks** using saved templates

## What should you check before using it?

1. **Accuracy.** Compare AI quantities with known final quantities on completed projects.
2. **Revisions.** Make sure takeoffs use the current drawing revision.
3. **Costs and data.** Check usage charges and data terms for your plan.

See [AI for BOQ and quantity takeoff](/insights/ai-for-boq-quantity-takeoff) for a pilot method.

## Frequently asked questions

### Can Civils.ai do takeoff from scanned drawings?

It measures from PDF drawings. Results are best from clear, vector PDFs; check scanned drawings carefully, and always compare with the current revision.

### Does Civils.ai train on my drawings?

Its terms state that Enterprise customer data isn't used for AI training, and its pricing page says data is never used to train models. Confirm the terms for your plan.

### Is there a free version?

Civils.ai offers free engineering calculators without login. The AI takeoff and checking tools are on monthly paid plans.
