AI for flooring Takeoff: Measure GFA/NFA & Finish Areas from PDF Plans

Streamline flooring takeoffs with AI. Civils.ai automatically measures Gross Floor Area (GFA), Net Floor Area (NFA), and finish areas from PDF plans — including scanned drawings — in metric or imperial. Get fast, accurate quantities, marked-up PDFs, and exportable reports for flooring estimates in minutes.

Why Flooring Estimators Use AI Assistance

Save precious time

Reduce hours spent tracing rooms and reconciling finish schedules so you can concentrate on pricing and strategy.

Keep numbers traceable

Draft outputs link back to the source drawings and notes, making reviews and clarifications easier with your team and clients.

Stay flexible

Addenda and changes happen. It’s simpler to update and re-issue a flooring takeoff when the groundwork is already prepared for you.

Quick demo
Getting started in minutes

Upload plan PDFs and write a simple prompt. A draft flooring takeoff (areas & finishes) is prepared and you’re notified when processing is completed.

Tip: Use clear prompts like “Prepare a flooring takeoff with GFA & NFA by level and zone; measure finish areas by room and type; exclude shafts/voids; include references.”

How It Works

  1. Upload your PDFs — Add architectural floor plans and any finish schedules or notes you want considered.
  2. Write your prompt — Tell Civils.ai what you need (for example: “Compute GFA/NFA by level; measure floor finish areas by type; split by zones.”).
  3. Click “Run” — The platform prepares a draft takeoff based on your uploaded drawings and schedules.
  4. QA review & adjust — Your team reviews the draft, confirms assumptions (e.g., area definitions), and fixes any issues before release.
  5. Share with confidence — Release reviewed drawings and quantities with clear references back to the source PDFs.

What the Draft Flooring Takeoff Can Cover

The goal is a clean starting point for pricing—prepared from your drawings and schedules—so your team spends more time refining and less time starting from scratch.

Typical items

  • GFA & NFA by level and/or zone
  • Room/space areas by floor finish type (e.g., tile, carpet, vinyl, timber)
  • Ceiling finish areas (optional) when schedules are provided
  • Site/plot hardscape & softscape areas (if included in plans)

Clarity about definitions

Area definitions (GFA/NFA) follow the notes in your drawings or the rules you specify. The system does not infer local standards; please provide inclusions/exclusions (e.g., shafts, balconies, parking, voids).

What to Expect (and What Not To)

Overview

What you can expect

  • A prepared draft flooring/area takeoff to help your bid
  • Clear references back to drawings and finish schedules
  • Faster internal reviews and fewer back-and-forths

Limitations to note

  • Not a 100% automated takeoff—human review is essential
  • GFA/NFA rules vary by client and jurisdiction—confirm inclusions/exclusions
  • Irregular atria/voids and mezzanines may require manual verification

FAQ

Is this suitable for busy bid periods?

Yes. It prepares a draft quickly so your team can review, adjust and price with confidence instead of starting from a blank page.

Can we trust the numbers?

Use the draft as a starting point. Your QA team checks and fixes anything that needs attention before releasing numbers to stakeholders.

Where do the quantities come from?

From the PDFs you upload—architectural plans and finish schedules. Everything stays traceable to the source pages for easy review.

What about complex shapes?

Irregular boundaries, large voids and multi-level atria are detected from plan outlines but may need manual verification. Confirm GFA/NFA rules with the client when in doubt.
