Takeoff for
Industrial
Piping & Steel
Accurate material and labor takeoff from isometric drawings in minutes, not days or weeks.
“Manual takeoff is grueling and time consuming. Purplefish gives our estimators a way to respond faster and bid more work without sacrificing control or accuracy.”
Manual takeoff is killing your estimating team.
Endless
data entry.
“We get a stack of 500 ISOs and we sit there for weeks typing every fitting into Excel. Drawing after drawing.”
Costly
errors.
“If you fat-finger one line item, your whole bid is wrong. Wrong price, wrong material order. And we’re doing this across a thousand drawings.”
Missed
revenue.
“We couldn’t get to at least 10 to 15 bids last year. Didn’t have enough estimator hours. Every one was a project we could have won.”
Wasted
talent.
“A good estimator is worth their weight in gold, and I’ve got them spending most of their time on data entry. That’s not what I hired them for.”
No
solution.
“We’ve looked at every takeoff tool out there. Nothing reads an ISO and actually pulls the material. So we do it all by hand, same as we did 16 years ago.”
Takeoffs More Accurate Than Humans (99.9%), That Keep Your Estimators In Control.
01
Upload & Extract BOMs and Weld Counts
Upload a packet of ISOs. Purplefish analyzes them using multiple custom models and extracts the takeoff in minutes.
02
Bid smarter, not just faster
Purplefish doesn't just extract. It highlights discrepancies, and items worth a closer look, so your estimators spend their judgment where it counts.
03
No black box
Every material line and weld count links back to the exact spot on the drawing. Your estimators can validate any number in one click, then export to Excel.
What if you got material out for pricing same day, every time?
