±0.3 yd³
accuracy vs ±1.5 eye-balling
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.
Olynx traces the outline on satellite and calculates yardage with configurable 5-8% waste per structure (slab, footing, wall, column, stairs). Rebar #3-#8 spacing schedule + tonnage + tie wire per ACI 318. Auto decision: direct chute / wheelbarrow / pump truck by distance. Subgrade haul-off with 1.20-1.45 swell factor.
- Per-structure take-off: slab, footing, wall, column, stairs
- 5-8% configurable waste + per-type thickness
- Rebar #3-#8 spacing schedule + tonnage + tie wire
- Auto decision: direct chute / wheelbarrow / pump truck by distance
- Subgrade haul-off with swell factor (1.20-1.45)
Mr. Patel driveway: trace outline (28×16 ft), 4" thickness, 7% waste = 11.2 yd³. #4 rebar @ 16" o.c. = 380 LF. Truck distance 65ft → pump truck recommended. Quote $5,840 in 6 min.
