ways to measure: your dimensions or a plan
Concrete take-off with ACI 318
Eye-balling a driveway: 11 yd³. Reality after proper measure: 12.4. Order 11, run short at 10 a.m. with crew + concrete truck already pouring. Call ready-mix for urgent 1.5 yd³ = $340 + $180 short-load fee. Margin lost.
Enter the dimensions (or upload a plan) and Olynx calculates yardage per structure (slab, footing, wall, column, stairs) with a waste allowance you set (5% by default). Rebar #3-#8 spacing schedule + tonnage + tie wire per ACI 318. You pick the placement method: direct chute, wheelbarrow, line pump or boom pump. Subgrade haul-off with 1.20-1.45 swell factor.
- Per-structure take-off: slab, footing, wall, column, stairs
- Waste you set (5% by default) + per-type thickness
- Rebar #3-#8 spacing schedule + tonnage + tie wire
- Placement you choose: direct chute, wheelbarrow, line or boom pump
- Subgrade haul-off with swell factor (1.20-1.45)
Mr. Patel driveway: enter 53×16 ft, 4" thickness, 7% waste = 11.2 yd³. #4 rebar @ 16" o.c. = 1,361 LF. Quote $5,840 in 6 min.
