The problem

Slow takeoffs are costing you

Contractors buy from whoever returns accurate numbers first. Every hour your team spends manually reading plans is an hour your competitor is quoting.

Manual takeoffs mean:

Estimator hours burned on every project

Throughput capped by headcount — growth requires more cost

Staff pulled from high-value work to read plans

Inconsistent accuracy across locations

The solution

Handoff-H1 — the first AI model purpose-built for autonomous construction takeoffs

General-purpose AI fails on complex connected systems like estimates and takeoffs. It reads the words; it doesn't know what they mean on a job site. Handoff-H1 does.

Built on computer vision trained on hundreds of thousands of blueprint pages, a curated construction knowledge base, and a consistency layer that reconciles the full set — H1 completes a full-scope takeoff in 90 minutes that automatically connects to your estimate.

How it works via API

01

Upload any plan format

blueprints, photos, PDFs, handwritten notes, spreadsheets. H1 reads it directly.

02

Get a structured takeoff

quantities identified by surface, pitch, and material type. Ready for review.

03

Map to your catalog + ERP

every line item priced to your SKUs and pushed to your quoting system.

Why H1 beats general AI

More accurate and faster than any other AI or estimator

H1 outperforms every general AI model — including GPT5.5, Claude, and Gemini — by more than 30 points. It even edges experienced human estimators.

The gap between H1 and the next best AI model is larger than the spread among all eight combined.
Even a human estimator with access to takeoff tools fell short by 4% and takes 1 week (vs. H1 at 2 hours).
