Concrete takeoff software that ends in cubic yards, not linear feet.
LF × width × depth ÷ 27 = CY for footings,
SF × thickness ÷ 27 = CY for slabs, with 8–10% waste presets built in — then your unit prices
turn it into a bid-ready .xlsx.
A real example, end to end
From an 800 sq ft ADU foundation plan (a public LA County standard drawing), measured and quoted in TakeoffQuote:
| Item | Measured | Assembly | Quantity | @ Unit price | Amount |
|---|---|---|---|---|---|
| Slab on grade, 4″ | 922 SF | SF × 4/12 ÷ 27, +8% waste | 12.3 CY | $310/CY | $3,811.88 |
| Strip footing, 1′×1′6″ | 140 LF | LF × 1.0 × 1.5 ÷ 27, +10% waste | 8.57 CY | $285/CY | $2,443.21 |
| Hold-down anchors | 4 EA | count | 4 EA | $95/EA | $380.00 |
| 03 — CONCRETE total | $6,635.09 | ||||
Unit prices are examples — the price book is yours, stored on your device. Every quote ships with a Basis tab showing the formula behind each line.
What the workflow looks like
| 1 · Trace the foundation plan | Areas for slabs, linears for footings, counts for anchors and piers — scales read automatically from the title block. Free, unlimited. |
| 2 · Bind assemblies | Tell each condition what it is: footing width and depth, slab thickness. Waste presets (10% footings, 8% slabs) applied — editable per bid. |
| 3 · Export the quote | Grouped under 03 — CONCRETE with your unit prices, subtotals, and terms. The .xlsx is what you email with the bid. Measured time for steps 2–3: about 3 minutes, vs 16–29 minutes doing the same in Excel. |
Concrete takeoff FAQ
How do you calculate concrete volume from a takeoff?
Footings: LF × width (ft) × depth (ft) ÷ 27 = CY. Slabs: SF × thickness (ft) ÷ 27 = CY. Add 8–10% waste for over-excavation and spillage, then price per CY. TakeoffQuote does this automatically when you bind a footing or slab assembly.
What waste factor should I use for concrete?
Common practice is 10% on strip footings (trench irregularity) and 8% on slabs on grade (subgrade variation). TakeoffQuote ships those as editable presets — your call per project.
Does it handle piers, walls, and grade beams?
Today's assemblies cover strip footings, slabs on grade, and counted items (anchors, piers as EA). More concrete assemblies are queued next — tell us which you need first.
Can I check a dimension against the plan?
Yes — the engine verifies against printed dimension strings (a measured 18'-0" grid span reads 18'1" at click precision), and every sheet's scale can be re-calibrated from two known points.
