Use this construction calculation for preliminary quantity, geometry, material, load, or coverage planning when dimensions and units have been measured consistently.

Required fill volume (m³)

Required number input.

Available cut volume (m³)

Required number input.

Subtract measured cut volume from measured fill volume; positive results mean imported fill is needed. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Net fill (+) or surplus cut (-) (m³)

The resulting net fill (+) or surplus cut (-) returned as a number.

• Earthwork volumes depend on survey surfaces, soil variability, swell and shrink factors, compaction target, groundwater, side slopes, haul conditions, and temporary works. Geotechnical and site-safety requirements remain separate.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify dimensions on site, use current product data and local code requirements, include an explicit waste or safety allowance where appropriate, and obtain qualified structural, electrical, plumbing, or geotechnical review when required.

• Block Core Fill Grout

  Calculate grout needed for fully filled block cores from block count and net fillable void per block.

• Concrete Order With Waste

  Calculate concrete order volume by adding a specified waste percentage to net placed volume; this is a purchasing allowance, not shrinkage prediction.

• Compaction Factor Adjusted Volume

  Convert loose soil volume to compacted volume using a measured compacted-to-loose volume ratio.
