AI for Glazing & Facade Takeoff: Elevation Areas by Cladding/Glazing Type

Automate glazing and façade takeoffs with AI. Civils.ai reads PDF elevation drawings, measures areas by cladding and glazing type, and delivers accurate marked-up PDFs and quantity reports for faster, more reliable estimating.

Why Facade Estimators Use AI Assistance

Save precious time

Reduce hours spent scanning elevations, façade schedules, and details so you can focus on pricing and strategy.

Keep numbers traceable

Draft outputs point back to the exact elevation sheets and schedules, 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 takeoff when the groundwork is prepared for you.

Quick demo
Getting started in minutes

Upload elevation PDFs (and any façade schedules) and run a simple prompt. A draft takeoff is prepared and you are notified when processing is completed.

Tip: Use clear prompts like “Prepare a glazing & facade takeoff by cladding and glazing type; split by elevation and floor zone; include spandrel vs vision where shown.”

How It Works

  1. Upload your PDFs — Add elevation sheets, façade details, and schedules you want considered.
  2. Write your prompt — Tell Civils.ai what you need (for example: “Prepare elevation areas by cladding/glazing type; split by elevation; include spandrel vs vision if identified.”).
  3. Click “Run” — The platform begins preparing a draft takeoff based on your uploaded drawings and schedules.
  4. QA review & adjust — Your QA team reviews the draft, fixes any issues, and confirms assumptions before release.
  5. Share with confidence — Release the reviewed drawing set and quantities to your stakeholders with clear references back to the source PDFs.
1 Upload elevation PDFs and choose Extract CAD data workflow
Upload PDFs

Drag & drop your elevation sheets and schedules, then select Extract CAD data. Works with scanned, historic, and multi-sheet drawings.

2 Describe elevation areas to extract and run
Type out your prompt

Type what you need in natural language (e.g. “measure façade elevation areas by cladding & glazing type; separate vision vs spandrel; split by elevation.”) Hit Run and the AI performs the takeoff and our QA team reviews the results.

3 Review façade results, references and export to Excel

What the Draft Takeoff Can Cover

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

Typical items

  • Elevation areas by cladding type (e.g., metal panel, stone, render)
  • Glazing areas split into vision vs spandrel (where identified)
  • Breakdowns by elevation and by floor zone/grid if shown

Clarity about heights

All height information is taken from the elevation/section drawings and specifications you provide. The system does not infer floor-to-floor heights beyond what is shown.

What to Expect (and What Not To)

Overview

What you can expect

  • A prepared draft takeoff to help your bid
  • Clear references back to the elevations and schedules
  • Faster internal reviews and fewer back-and-forths

Limitations to note

  • Not a 100% automated takeoff—human review is essential
  • Heights are taken strictly from your drawings/specs; no height inference
  • Free-form/double-curved 3D surfaces are not supported (2D elevation area basis)

  • Cladding
  • Glazing
  • Formwork
  • Split by type

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—elevations, façade schedules, and details. Everything stays traceable to the source pages for easy review.

What about complex shapes?

We don't handle free-form/double-curved façades. For standard elevations and categories shown in the documents, the tool prepares a draft your team can finalize.

Prepare Stronger Glazing & Facade Bids with Civils.ai

Upload your elevation drawings and schedules, write a quick prompt, click run—then let your QA team review and release a clear, traceable takeoff.

Civils.ai is an assistive tool for bid preparation. Final quantities and assumptions should be reviewed and approved by qualified professionals.
