Free quantity take-off for construction
Quantities from a drawing.
With the working shown.
Upload one drawing sheet and get a draft schedule. Tagged doors, windows and equipment are counted and marked on the drawing, so you can see where each one came from. Lengths and areas come back as candidates, each with the reason it still needs checking.
Take off a drawingSee an exampleFree. No account needed. Five take-offs a day.
In development. Counting tagged items is the most developed part; lengths and areas are for checking. Check every quantity, and look for anything missed, before you price or order. Where we are
| Item | Quantity | Status |
|---|---|---|
| Window (tagged W) | 9 nr | Passed checks |
| External door (tagged ED) | 2 nr | Passed checks |
| Roof access ladder (tagged RAL) | 1 nr | Check |
| TYPE 1 Facing brick | 151.20 m² | Candidate |
| TYPE 2 Plinth | 36.00 m | Candidate |
Free tool
Take off a drawing
One sheet at a time: a single-page PDF, or a PNG or JPEG. A PDF exported from CAD usually gives a better result, because the tool can also read the text it carries. A take-off usually takes several minutes.
Before you choose a drawing: we keep it for 90 days and people at PlanOps may look at it to improve the tool. Only upload a drawing you are allowed to share.
Each number points back at the drawing.
From sheet to schedule
A first pass,
made easy to check.
A take-off is only as useful as your confidence in it. So the tool shows where each quantity came from, says so when it is not sure, and leaves the decision to you.
- 01
Upload one sheet.
A layout, plan or elevation with a legend or tagged items. The sheet is read first for what it is for, so a services layout is taken off for its services and not for the walls drawn behind them.
- 02
See what was found, on the drawing.
Each item the tool identifies is marked where it was found. Counts come from the printed tags, checked against the symbol on a close-up. Lengths and areas are traced and measured from the scale the sheet prints.
- 03
Check it, mark it up, take it away.
Quantities that passed the tool’s own checks are kept apart from candidates, and what it noticed it could not assess is listed. Mark a line right or wrong and give your own figure: the file you download carries the tool’s quantity and yours side by side.
Where we are
Counting first.
Still learning to measure.
Quantity take-off is being built in the open. This is what it can and cannot do as of 13 November 2026.
Most developed
- Counting tagged itemsDoors, windows, equipment and devices that carry a printed tag are found from the tag, checked against the symbol on a close-up at full resolution, and counted once. Each one is marked on the drawing.
- Taking off what the drawing is forThe sheet is read first for its discipline and purpose. A security layout is taken off for security equipment, and the walls and doors drawn as background are left out.
- Scale and “Do not scale”Scale is taken from what the sheet prints: levels, scale bars and stated scales, checked against each other. A scale nothing on the sheet supports measures nothing, and a sheet marked “Do not scale” says so on every measured quantity.
- Showing the evidenceEvery line says how it was identified, where it is, how it was measured and what is still unresolved. A quantity that fails a check is kept and shown as a candidate, and never added to an accepted total.
For checking
- Lengths and areasThis is the weakest part. On our latest test runs no length or area passed its own checks, so none passes automatically. Treat every one as a starting point to measure against.
Not yet
- Items with no tagWe cannot yet show that all of them are found, so an untagged count may have omissions.
- Scanned and image-only drawingsMuch of the checking relies on the text a CAD-exported PDF carries. Without it, fewer checks run, so scanned drawings are likely to be less accurate.
The exchange
Free while we improve it together.
You get a draft take-off to check and download. With your agreement, we keep the drawing and the result for a limited period so our team can find where it went wrong and test improvements.
- What we keep
- We keep the drawing you upload, an image of it and the result for 90 days, then delete all three.
- Who sees it
- People at PlanOps may look at them to find where the take-off was wrong and to test fixes. They are not published, sold or shared outside PlanOps and the services that run it.
- Your control
- You can delete a take-off and its drawing at any time from its result page. Only upload a drawing you are allowed to share: the form asks you to confirm it.
- The daily limit
- To keep five a day fair, the site sets one cookie and makes a scrambled key from your connection and browser. Neither is used for anything else, and the keys are discarded the next day.
The bigger job
Your drawing is only
one part of the job.
In PlanOps, project drawings and their revisions sit alongside the questions and records your team needs to manage the work. Quantity take-off is being developed for PlanOps and is not in it yet.
On this page
- One sheet at a time, five take-offs a day
- A draft schedule you check yourself
- Kept for 90 days, then deleted
- A CSV file, with your own checks, to carry into your estimate
In PlanOps today
- Whole drawing sets, with their revisions
- What changed between two revisions, kept in a change register
- RFIs raised from what the drawings change or leave unclear
- The project’s documents, programme and quality records alongside
Planned for quantity take-off
- Quantities kept with the drawing they came from
- What a new revision does to the quantities
- Your corrections kept with the project, not only in a download
Beyond one sheet
Your drawings already
have a home in PlanOps.
Project drawings, their revisions and the questions they raise are managed in PlanOps today. Quantity take-off is being developed to join them.

A few useful details.
What is a quantity take-off?
A quantity take-off is the list of what a drawing shows and how much of it there is: how many doors, what length of duct, what area of wall. It is the starting point for pricing, ordering and planning the work. This tool produces a draft of one from a single drawing sheet and shows where each quantity came from.
How accurate is it?
We do not yet have an accuracy figure we would stand behind, and we would rather say so than quote one. It has been tested on a small set of drawings we know well. Counting items that carry a printed tag is the most developed part, and it still misses, duplicates and misreads items. Lengths and areas are not yet reliable and are shown only as candidates. Read the 'Where we are' page for the detail, and check every quantity before you use it.
What can I upload?
One sheet: a single-page PDF, or a PNG or JPEG image. A multi-page PDF is refused, so export the one sheet you want. A PDF exported from CAD usually works better. A scan is accepted, but fewer checks can run on it.
Why do you keep my drawing?
Because that is how the tool improves. We keep the drawing and its result for 90 days so that people at PlanOps can find where the take-off went wrong and test fixes against real sheets. They are not published or shared outside PlanOps and the services that run it. You can delete a take-off and its drawing at any time from the result page.
Why only five a day?
Each take-off is several minutes of computing that we pay for, and the tool is free. The limit keeps the cost of a free tool in development manageable and keeps it open for everyone. The allowance resets at midnight, UK time.
Does this replace a quantity surveyor or an estimator?
No. It does a first pass at the reading and counting, and shows its working to make the checking easier. Deciding what is in scope, which measurement rules apply, whether anything is missing and what the quantities mean for the price is still a person's job.
When will it be in PlanOps?
Once it has been tested on a wider set of drawings and meets the standard we set for relying on it inside a project. Leave your email address and we will tell you when it is.
