Formula & Mathematical Methodology: Soil Swell & Shrinkage Formula

LooseCuYd (LCY) = BankCuYd × (1 + Swell%)
CompactedCuYd (CCY) = BankCuYd × (1 − Shrinkage%)
LooseCuYd (LCY) = BankCuYd × (1 + Swell%); CompactedCuYd (CCY) = BankCuYd × (1 − Shrinkage%)
  • bankVolumeCuYd: Bank Volume Cu Yd (BCY)
  • soilSwellFactorPct: Soil Swell Factor Pct (%)
  • compactionShrinkagePct: Compaction Shrinkage Pct (%)
  • dumpTruckCapacityCuYd: Dump Truck Capacity Cu Yd (LCY/truck)

Rounding: Physical package counts round up where appropriate; continuous measurements round to 2 decimal places.

Worked Example: Practical Benchmark: Soil Swell & Shrinkage

Convert Bank Cubic Yards (BCY) into swelled truck haul-off volume (LCY) and CCY.

  1. Enter your project dimensions, machining speeds, or recipe weights.
  2. Compute the governing equation: LooseCuYd (LCY) = BankCuYd × (1 + Swell%); CompactedCuYd (CCY) = BankCuYd × (1 − Shrinkage%).
  3. Review the primary result, supporting dimensions, and 3 SVG visualizations.
Result: Computes Soil Swell & Shrinkage via LooseCuYd (LCY) = BankCuYd × (1 + Swell%); CompactedCuYd (CCY) = BankCuYd × (1 − Shrinkage%).

Earthwork Excavation Bank, Loose Swell & Compacted Cubic Yards Calculator: inputs, method, and how to read the result

Convert Bank Cubic Yards (BCY) into swelled truck haul-off volume (LCY) and CCY.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Bank Volume Cu Yd: In-situ undisturbed excavation volume in Bank Cubic Yards (BCY).
  • Soil Swell Factor Pct: Excavation bulking / swell percentage (15% sand, 25% common earth, 35% clay).
  • Compaction Shrinkage Pct: Compaction shrinkage percentage relative to bank volume (%).
  • Dump Truck Capacity Cu Yd: Haul truck bed loose capacity in cubic yards.

What the calculation includes

With the default values shown, Excavated Loose Volume (LCY) is 150 LCY. The calculation follows Soil Swell & Shrinkage Formula; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Bank Volume Cu Yd from 120 BCY to 132 BCY changes Excavated Loose Volume (LCY) from 150 LCY to 165 LCY. This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses standard North American & metric trade dimensions, Machinery’s Handbook formulas, and culinary weight ratios.
  • Verify local municipal building codes, tool manufacturer limits, and food-safety time/temperature tables before execution.

Scope: Trade, Shop & Culinary Science Reference Standard Check the assumptions and limitations against your situation before relying on the estimate.
