Material takeoffs from piping isometrics

The takeoff doesn't have to take all week.

PipeTakeoff reads the bill of materials on every isometric, builds the MTO and prices it from your own catalog and past quotes. Your estimators check lines instead of typing them, so the same team can bid more work.

  • 1,000 free extractions with an account, no card
  • Nothing reaches your MTO until an estimator commits it

01 · How it works

Upload the isos. Review the lines. Export.

  1. 01

    Upload isos

    Drop the whole bid package as one PDF. Every page is sorted for you: isos, BOM continuation sheets, P&IDs, plans, spec sheets. Confirm the split and the isos go to extraction.

  2. The review screen in dark mode: the iso on the left, the lines read from its BOM table on the right.
    02

    We read the BOM table

    Whatever columns your BOM prints, in whatever layout: qty, size, schedule, material, description and spec, plus material codes and valve tags. Each line gets a confidence score.

  3. A flagged line selected on the review screen, with its callout boxed on the drawing.
    03

    Review, commit, export

    A grid that works like Excel. Commit the lines to your MTO once you've checked them, then export it, priced from your catalog and past quotes, to xlsx or csv.

The whole run on the real screen: one package PDF in, split into drawings, reviewed, committed and exported to xlsx. 2 min.

02 · The review screen

Click a line. See where it came from.

Your estimators check lines instead of typing them. Every flagged row says why it was flagged. Open the sample, fix the flagged lines and commit it, right in your browser.

Try the interactive demo
Review is a required step

Every extraction goes to an estimator first. Nothing reaches your MTO until they commit it.

Flagged rows say why

Low confidence, a description cut short, conflicting specs: the reason is printed on the row.

Every decision is on the record

Every edit, commit and re-extract is written to a hash-chained audit log, so a changed entry shows.

03 · After the takeoff

The committed MTO keeps working through revisions, quotes and pricing.

Rev B arrives Friday at 4. Immediately see what changed.

Each new revision is compared line by line against the last one you committed. Lines already on an RFQ are flagged, so you know before material is ordered.

Start with the four changes

Filter the grid to what changed: removed, added, quantity and attribute changes against the last committed revision.

Know when a change hits an RFQ

See if any of the changes in the latest revision impact RFQs that have already been sent out or bids that have already been received.

See the change on the drawing

Switch the drawing between Rev A and Rev B, with the changes highlighted on the drawing.

You stay in control

Nothing reaches the MTO until an estimator commits the revision, and the commit is written to the audit log.

From the founder

Why I built PipeTakeoff.

I spent years doing material takeoffs (MTOs) by hand. The work was the same every time: open a PDF, count fittings, type rows into Excel, double-check schedules, and pass the MTO to a buyer. The drawings kept changing, and the takeoff and RFQs would inevitably fall behind.

PipeTakeoff.com is the tool I wish I had. Upload the iso, and it reads the BOM table printed on the drawing into an MTO for you to review, then exports to the format your buyer expects.

You stay in the loop. The AI never commits on its own: you check every line against the drawing and you make the calls. The typing goes away.

What does the free tier cover?

Your first project, up to 1,000 extractions in total, and up to 5 RFQs with 5 vendors each. No credit card and no time limit. Re-extracting a drawing counts as another extraction.

How does the paid plan bill?

$399 a month includes 1,000 drawings. Each drawing above that in the same month adds $0.50. A drawing is billed once, the first time it is extracted, so revisions, re-extractions and quote review never add to it. The allowance resets on the 1st of each month (UTC).

Is there a limit on drawings?

No. Above 1,000 drawings in a month, each drawing adds $0.50. Users and projects are unlimited.

How accurate is it?

It reads what the BOM table says, and it marks the lines it is unsure of. Every change to the extraction is tested against drawings graded by hand, and a change that reads worse doesn't ship. Either way, an estimator checks every line before it goes into the MTO.

Will it read our drawing style?

Yes, with nothing to set up. It reads the BOM table however your drawings lay it out, including material or item codes and valve tag numbers when the table has those columns. Tags that appear only as callouts on the drawing, outside the BOM table, aren't read yet.

What does switching cost?

Nothing to migrate. Upload the drawings on your desk; export xlsx and send RFQs exactly as you do now. How to evaluate AI pipe takeoff software

Do you train on our drawings?

No. We never train or fine-tune on customer drawings, and our model provider's commercial terms prohibit it.

Where is my data?

Stored in the US: PDFs in Cloudflare R2, structured data in Neon Postgres (US-East). Row-level isolation is enforced at the database.

Don't take our word for it. Try it on one of your drawings.
