Description

Start chainage

Enter the first chainage of the range of chainages for which volumes should be calculated.

Stop chainage

Enter the last chainage of the range of chainages for which volumes should be calculated.

Start volume

Enter the volume that should be added to the overall run to accommodate arbitary items such as borrow material, bellmouths, culverts, etc.

Topsoil to strip (m)

Enter the depth of topsoil that should be stripped from cross-sections before volumes are calculated.

Compaction < 100% < Bulking

Enter the bulking or compaction factor that should be applied to calculated cut volumes. Factors of over 100 imply bulking while factors under 100 imply compaction. A value of 100 will ignore any form of bulking or compaction.

Existing Ground Layer

Select the existing ground layer for volume calculations.
