Concrete estimating for owners who pour their own jobs
Draw the slab.
Get the bid.
Trace the pour on screen. Get the yards, the rebar and a bid you can send, then run the crew and get paid from the same drawing.
$44/mo. Every feature included. 14-day free trial.
01 · Draw
Trace it once.
Click the corners of the pour on a photo of the site or your plan. Drag any point to adjust. Curves, bump-outs and L-shapes are drawn as they are.
02 · Yards
The yards follow.
Area and thickness turn into cubic yards, rebar and waste as you draw. Overlaps are added for each bar size. Every number traces back to a rate you set.
03 · Bid
Send it.
Get it signed.
The cost sheet and proposal are already built from your own prices. Review it, send it, and follow up on the ones that go quiet.
04 · Build
Run the crew.
The job on the crew's phones, the clock, the day's log and the receipts. They see the work, never your prices.
05 · Paid
See what
it made.
Change orders, invoices and timesheets, with the bid next to what the job really took.
Why ConCal
Built by someone who had to order the concrete.
In 2023 I was pouring a slab with weird angles for a contractor, and my boss asked me to figure out how much concrete to order. I worked it out by hand. It took hours, and I still worried I had it wrong. Every calculator I could find did circles, squares and rectangles, so I built the one we actually needed.
What it takes off
Bid the pours you actually do.
If you can sketch it, it prices it. Every shape is drawn in its own projection and quantified to the yard.
Driveways
Curves, flares and bump-outs drawn as they are, not boxed into a rectangle.
Slabs on grade
Thickened edges, rebar, wire mesh and base rock from the drawn shape.
Footings
Continuous footings by the foot, with your own cross-section.
Garage aprons
Apron, approach and saw cuts on one sheet.
Walks and patios
Waste set per shape and pour condition, not a flat 10% on everything.
Stem walls and columns
Walls and column grids, each priced from what you drew.
Profit leaks
Stop the leaks before the pour.
Five things quietly eat margin on a hand-run job. ConCal closes the first three when you draw, and the last two before payday.
- 01Waste set per shape and pour condition
- 02Rebar overlap added for each bar size
- 03Exact yards from the drawn shape, not a guessed box
- 04Changes after signing become change orders
- 05Missed punches flagged before payroll
Straight answers
What owners ask first.
Does it work on my phone, in the truck?
Yes. ConCal runs in any phone, tablet or laptop browser, nothing to install. Your drawing autosaves on the device as you work, and cloud sync catches up when you're back on signal.
Do I have to enter my own prices?
Yes, on purpose. ConCal never guesses regional averages. Setup takes your real supplier quotes and labor rates, so every bid is your number. Change a price once and every future bid uses it.
Does my crew need their own plan?
No. One plan covers everyone, office and crew. Each person gets their own login, and foremen and workers see the job on their phone without seeing your account or your prices.
What happens after the 14-day trial?
It's $44/mo if you stay. Nothing is charged until the trial ends, and your projects, price book and proposals stay saved either way.
Is my pricing private?
Your price book and bids live in your account and go only where you send them: a proposal PDF or a share link you create. No marketplace, no selling your numbers, cancel whenever.
