Construction TAKEOFF & ESTIMATING

AI-Powered Platform for Faster, More Profitable Bids

STACK is the cloud-based preconstruction platform where estimating teams complete faster takeoffs, build sharper estimates, and turn every project into measurable revenue, profit, and win-rate growth.

STACK Helps Drive Real Results

Revenue Growth

Faster, more accurate estimates mean more bids won and in the pipeline.

Project Profitability

Accurate estimates stop leaks that erode margin so you keep the profit.

Faster Takeoffs

More speed means more bids, and more bids mean more wins.

Thousands of contractors, suppliers and owners trust STACK to bid faster and win more work.

From first takeoff to final number.

Whether you're evaluating a new bid or working to keep your field crews on track, STACK solutions accelerate your workflows and drive efficiency throughout the construction project lifecycle.

Evaluate

Upload plans and specs. STACK AI reads every sheet, auto-names pages, and flags revisions the moment they land.

Takeoff

Measure linear, area, count, and volume in clicks — with AI auto-counting symbols and suggesting scope you might miss.

Estimate

Quantities flow straight into live estimates. AI pressure-tests pricing while your team works the same numbers in real time.

Build

Carry the same scope and budgets into the field — RFIs, daily reports, photos, and markup keep the build on track without rekeying a thing.

Robust and Accurate Takeoff Tools

Measure linear, area, count, and volume with pixel-perfect accuracy. Overlay drawing versions to catch every change.

Worksheet-Style Estimating

Flexible, spreadsheet-style estimating with items and assemblies. Rollup and group by takeoff, tag, or label — any dimension you need.

Collaborate from Anywhere

100% cloud-based. Unlimited viewer seats. Mark up plans, share estimates, and keep the whole team aligned — from any device and any location.

STACK AI

The AI platform built for preconstruction teams.

STACK pioneered digital takeoff for the cloud. Now we've put AI at the center of it. Not just a chatbot bolted on the side. STACK AI is trained on the way preconstruction actually works, so it amplifies your team's judgment instead of replacing it.

AI Plan Intelligence

Reads, indexes, and understands every sheet the moment it's uploaded.

AI Project Assistance

Ask STACK Assist questions about scope, specs, and quantities and get immediate, accurate answers.

AI Takeoffs

Auto-counts symbols and suggests measurements so quantities take minutes, not days.

AI Margin Insights

Flags risk, gaps, and pricing drift before the final bid goes out the door.
