Ready-Mix Concrete Order (Trucks, Waste, Short Load)
How much ready-mix to order, how many trucks that is, and whether a short-load fee applies.
Example
You enter
- Required in-place volume (yd³) 42
- Waste/over-order allowance (%) 8
- Truck capacity (yd³, default 10) 10
- Plant minimum before short-load fee (yd³) 10
You get
- Ordered yd3 45.36
- Trucks 5
- Last load yd3 5.36
Details, formula, and sources
Ordered = in-place volume x (1 + waste%), trucks = ceil(ordered/capacity), short-load fee below the plant minimum. 42 yd^3 at 8% waste, 10 yd^3 trucks -> 45.4 yd^3, 5 trucks, 5.4 yd^3 last load, no fee; a small 6 yd^3 pour trips the sub-10 yd^3 short-load fee. Ordering a little long beats a second delivery. The supplier's terms govern.
ordered = volume x (1 + waste%); trucks = ceil(ordered / load); last_load = ordered - (trucks-1) x load; short_load if ordered < min.
Ready-mix concrete ordering (volume, waste allowance, truckloads, short-load minimum), standard concrete-supply practice, by name.
The waste-allowance, truckload, and short-load-minimum arithmetic is public; the truck size, plant minimum, and fee schedule come from the supplier.
Estimate. AHJ and licensed professional govern.
