From measurements to materials
Measured volume = length × width × depth × quantity. Adjusted volume = measured volume × user-entered factor.
Put the numbers in context
A 5 m × 1 m × 1 m trench is 5 m³ measured volume before any bulking, shrinkage or handling factor.
This illustrates the method; your inputs determine your result.Assumptions to check
- Each repeated zone has the same dimensions.
- The volume factor is supplied for the applicable soil and operation.
Limits of this calculation
- Side slopes, shoring, groundwater, disposal distance and soil classification are not determined by the calculator.
Common questions
What belongs in the volume factor?
Use a value provided for the project’s soil and operation. Leave 1.0 when no adjustment is being applied.
Will this tell me a safe excavation slope?
No. Excavation safety and shoring require site-specific professional decisions.
