Slow Manual Takeoffs
Construction estimators waste days on slow, error-prone manual takeoffs and struggle to turn drawings into accurate bids.
In their words
does anyone else hate having to do take offs in Bluebeam?
Create something that can take 2 pages of interior wall sections, 3 pages of specs on tile with different grout and tile sizes, different wall heights and tile locations and spit out true quantities
if I'm doing 2 hours of drawing and take-off work, I need paid for that
I feel like we’re letting money go by not submitting just because I can’t figure this out.
There are programs for multifamily. We tried one for a few months that was solid but it was $2,500/mo so we didn’t continue
Most of the software I've tried is great for takeoffs on walls and areas, but counts are slow and tedious.
Fable is able to understand blueprints WAY better than any previous Claude model. I can actually use it to check an estimator's work with reasonable accuracy.
I've been taking off plans very old school like with the paper plans before me, highlighters and a yellow note pad.
Problem : Reinforcement Takeoff ... What you have already tried : Using ratios from Concrete Volume
Half the time I just need someone to clean up my mess in Excel and make it look professional before sending to client.
Ive had two accounts quit because im so disorganized with my paperwork
the biggest problem is variety of different drawings, small details etc.
Construction estimators
Where they talk
- r/estimators
- r/Construction
- r/Contractor
- r/CounterTops
- r/ConstructionManagers
- r/electricians
- r/vibecoding
- r/ConstructTech
Tools they use today
- Excel
- Bluebeam
- Planswift
- Claude
- zzTakeoff
- On-Screen Takeoff
- OST
- Stack
Why those fall short
- Drawings lack standards, legends and dimensions; RFI answers are incoherent or slow.
- AI cannot distinguish wall types, misses columns and footnotes, output unusable
- not fully switched; nothing digitized for measuring or takeoffs
- fails to accurately read vertical text and column size changes
- cost and manual modeling hard to justify; still must assign elevations manually
