Level this plot to 0.625 m by planning for 123.75 m³ (4,370.19 cft) cut and 142.313 m³ (5,025.72 cft) fill.

Borrow Fill Needed: 18.562 m³ (655.53 cft)

Fill volume is greater than cut after allowances. Plan to import approved borrow fill from an outside source.

Soil fill quantity calculation

This page focuses on fill soil for a 25 m x 18 m area (450 m²) with a 0.55 m level difference — the raw fill requirement is 123.75 m³, rising to about 142.31 m³ after a higher 15% compaction allowance (reflecting looser borrow soil that settles more once placed).

At a 6 m³ truck capacity and 75 m³/day site output, that's about 24 truck trips over 2 working days, costing roughly 93,122 at the sample rate of 350 per m³ applied to the combined 266.06 m³ handling total.

  • Area: 25 m x 18 m.
  • Fill compaction: 15%.
  • Fill needed: ~142.3 m³.

How the land leveling calculation works

Land leveling compares existing ground levels with a target level, then converts the level difference into cut volume, fill volume, handling quantity, and practical site estimates.

Step 1 - Calculate plot area

Plot Area = Length x Width

The calculator first converts plot dimensions to meters and calculates total area. This area is used for the simple high-low estimate and is also divided across spot levels in grid mode.

Step 2 - Choose the target level

Simple Mode Target = (Highest Level + Lowest Level) / 2
Grid Mode Target = Average Spot Level or User Target Level

In simple mode, the target level is the midpoint between the highest and lowest points. In grid mode, the calculator uses the entered target level, or if left blank, it balances cut and fill around the average of all grid spot levels.

Step 3 - Calculate cut and fill volume

Simple Mode:
Height Difference = Highest Level - Lowest Level
Cut Volume = Plot Area x (Height Difference / 2)
Fill Volume = Plot Area x (Height Difference / 2)

Grid Mode:
Cell Area = Plot Area / Number of Spot Levels
Point Volume = |Spot Level - Target Level| x Cell Area

In simple mode, the calculator assumes the plot balances around the midpoint, so the same average depth is used for both cut and fill. In grid mode, each spot level is compared with the target level to decide whether that point requires cut, fill, or no adjustment.

Step 4 - Apply soil allowances

Adjusted Cut = Cut Volume x (1 + Cut Soil Allowance / 100)
Adjusted Fill = Fill Volume x (1 + Fill Compaction / 100)

Cut allowance can represent bulking, shrinkage, or practical handling loss. Fill compaction allowance increases loose fill quantity so the required compacted fill can be achieved on site.

Step 5 - Calculate handling, trips, days, and cost

Total Handling = Adjusted Cut + Adjusted Fill
Trip / Day Quantity = Maximum of Adjusted Cut or Adjusted Fill
Trips = Trip / Day Quantity / Vehicle / Trolley Capacity
Days = Trip / Day Quantity / Earthwork Output per Day
Cost = Total Handling x Cost per m³

The calculator adds adjusted cut and fill to estimate total soil handling. For trips and daily productivity, it uses the larger of adjusted cut or adjusted fill so transport planning does not double count the same soil movement.

Therefore, this 450 plot needs a target level of 0.625 m, with 123.75 adjusted cut and 142.313 adjusted fill, requiring 24 trips over 2 days at an estimated cost of 93,122. Because fill is greater than cut, this job needs to borrow in an extra 18.562 m³ of fill material.

FAQ

About 142.31 m³. Raw fill is 450 m² x 0.275 m (half the 0.55 m level difference) = 123.75 m³, which becomes 123.75 x 1.15 = 142.31 m³ after the 15% compaction allowance.
15% reflects a looser or more variable borrow soil that needs a bigger allowance to reach the target compacted level — the allowance is fully editable, so use a lower figure for a denser, well-graded fill material or a higher one for loose, poorly-graded soil.
