Level this plot to 1.264 m by planning for 124.775 m³ (4,406.39 cft) cut and 133.093 m³ (4,700.15 cft) fill.

Borrow Fill Needed: 8.318 m³ (293.76 cft)

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

Site leveling from grid spot levels

This page uses grid mode with 9 survey spot levels across a 45 m x 30 m site (1,350 m², 150 m² per cell) — with no target level entered, the calculator balances around the average of all 9 levels (1.264 m), giving 118.83 m³ of raw cut and the same raw fill.

After a 5% cut shrinkage allowance and 12% fill compaction, that's 124.78 m³ of adjusted cut and 133.09 m³ of adjusted fill — needing about 17 truck trips at 8 m³ per load and 2 working days at 120 m³/day output.

  • Site: 45 m x 30 m, 9 spot levels.
  • Target: average of levels (1.264 m).
  • Total handling: ~257.9 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 1,350 plot needs a target level of 1.264 m, with 124.775 adjusted cut and 133.093 adjusted fill, requiring 17 trips over 2 days at an estimated cost of 83,807. Because fill is greater than cut, this job needs to borrow in an extra 8.318 m³ of fill material.

FAQ

The calculator uses the average of all entered spot levels — for this page's 9 levels (1.10 through 1.62 m), that average works out to 1.264 m, which becomes the balancing target that every point is compared against to decide cut or fill.
118.83 m³ of raw cut and 118.83 m³ of raw fill (they happen to be very close for this specific level set), becoming 124.78 m³ adjusted cut (5% shrinkage) and 133.09 m³ adjusted fill (12% compaction).
