Waste factor miscalculations
A flat 10% on every pour over-orders simple slabs and under-orders anything with sub-grade variation. ConCal applies waste per shape, per pour condition.
Waste set per shape — not per habitDraw the slab on screen. ConCal returns cubic yards, rebar with Class B laps, waste factor, and a bid-ready cost sheet — before the coffee goes cold.
Every contractor has bid a job from a bounding box and a hunch — and eaten the short-load fee when the math came up a yard light. Drag the handle.
Jobs aren't rectangles. Slabs, bump-outs, radius work, stem walls, column grids — drawn in their own projection, quantified to the yard.
Three line items quietly eat margin on hand-figured bids. ConCal closes each one at draw time — not at the plant.

Waste set per shape — not per habitClass B lap lengths change with bar size, and napkin math rounds them off. ConCal adds laps to every run automatically and totals true LF.
Class B laps added per bar sizeEyeballing an L-shape as a rectangle pours concrete into ground that isn't yours. Drawn polygons compute the exact CY of what you'll actually form.

Slabs, L-shapes, bump-outs, curves. Snap vertices, get exact square footage.
Continuous footings by LF, stem walls by height, columns by count — one takeoff.
Mix PSI, pump time, short-load fees, labor — totaled into a number you can sign.
Works offline in the truck, dark mode for 5 AM pours, autosaves every change.
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. Dark mode for the 5 AM pours.
Yes — on purpose. ConCal never guesses regional averages. The 2-minute setup takes your real supplier quotes and labor rates, so every bid is your number, not somebody's national estimate. Change a price once and every future bid uses it.
Slabs with bump-outs and curves, L-shapes, thickened edges, continuous footings by the foot, stem walls, and columns — with rebar (Class B laps included), wire mesh, base rock, and saw cuts computed from the drawn geometry. If you can sketch it, it prices it.
It's $44/mo if you stay. No card to start, nothing charged until you subscribe, and your projects, price book and proposals stay saved in your account either way.
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.
Draw it once. The yards, the rebar, the dollars — done before the plant picks up.
