Keep the quantity basis clear
Bank means material in the ground. Loose means excavated material after swell. Compacted means placed material after a separate shrink or expansion factor. Tons and cubic yards are linked using the material density for the same volume basis.
Loose = bank × (1 + swell / 100). Compacted equivalent = bank × (1 − shrink / 100). Net weight = loose volume × loose density.
These are planning quantities, not protective-system designs. Verify material factors, dimensions and legal truck limits with project data. Example presets are not tested site values.
