How to Use This Calculator
  1. Enter Unit Length, Unit Width, and Depth (North).
  2. Set Depth (South), Depth (East), and Depth (West).
  3. Adjust Slope/Irregular Correction as needed.
  4. Review Volume (m³) and Estimated Person-Days.
  5. Use Average Depth (m) and Depth Variation (m) to inform your decision.

What each input means

Unit Length
North-south dimension of the excavation unit.
Unit Width
East-west dimension.
Depth (North)
Layer depth at the north profile.
Depth (South)
Layer depth at the south profile.
Depth (East)
Layer depth at the east profile.
Depth (West)
Layer depth at the west profile.
Slope/Irregular Correction
Additional volume for irregular surfaces and slopes.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Unit Length = 2, Unit Width = 2, Depth (North) = 0.15, Depth (South) = 0.12 = 7 input(s) provided
  2. Calculate Volume
    Volume
    0.578 = 0.578
  3. Calculate Estimated Person-Days
    Estimated Person-Days
    1.2 = 1.2
  4. Calculate Average Depth
    Average Depth
    0.138 = 0.138
  5. Calculate Depth Variation
    Depth Variation
    0.08 = 0.08
