Earthwork

Cut/fill volumes with swell, shrinkage, and truck-load estimates.

Volume method

Calculation method

Length (ft)Width (ft)Depth (ft)

Swell (%)Common: sand 12%, clay 25%, rock 50%Shrinkage (%)Common embankment 10–20%Truck capacity (cy)End-dump ~14 cy, belly ~20 cy

Bank volume148.15cy

Bank volume4,000cf

Loose (after swell)185.19cy

Compacted (after shrink)125.93cy

Truck loads (loose)13.2loads

Bank volume is the in-place, undisturbed volume.
Loose volume is what you haul. Compacted volume is what fits in the embankment after compaction.
Average end-area method: V = L × (A₁ + A₂) / 2.
