High & Low Levels

ℹ️The simple method balances to the midpoint between highest and lowest levels.

Level this plot to 1.25 m by planning for 150 m³ (5,297.2 cft) cut and 165 m³ (5,826.92 cft) fill.

Borrow Fill Needed: 15 m³ (529.72 cft)

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

Land leveling cut and fill estimate

This page is pre-filled for a 30 m x 20 m plot (600 m²) with a 0.5 m level difference (1.5 m high point, 1.0 m low point) — the simple high-low method splits that evenly, giving 150 m³ of cut and 150 m³ raw fill, or 165 m³ after 10% fill compaction allowance.

Total handling comes to 315 m³, needing about 33 truck trips at 5 m³ per load and 3 working days at 80 m³/day site output, for an estimated cost of 94,500 at the sample rate of 300 per m³.

  • Plot: 30 m x 20 m.
  • Level difference: 0.5 m.
  • Total handling: 315 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 600 plot needs a target level of 1.25 m, with 150 adjusted cut and 165 adjusted fill, requiring 33 trips over 3 days at an estimated cost of 94,500. Because fill is greater than cut, this job needs to borrow in an extra 15 m³ of fill material.

FAQ

150 m³ of cut and 150 m³ of raw fill. Area is 30 x 20 = 600 m²; the 0.5 m level difference (1.5 - 1.0) is split evenly, so each of cut and fill uses half that depth (0.25 m) across the full 600 m² area: 600 x 0.25 = 150 m³.
Because a 10% fill compaction allowance is applied to fill only, not cut — 150 m³ x 1.10 = 165 m³. This extra loose fill volume accounts for the fact that placed fill settles and needs more material to reach the target compacted level.
