TryBuildCalcSand Estimation & Procurement Verification Checklist
🕒 Last updated: June 28, 2026
Essential Checklist+−
Complete these critical checks before approving the work or proceeding to the next construction stage.
✓13 Inspection Points
✓3 Verification Categories
✓Volume Estimation & Formula+-
- Sand application confirmed — concrete, masonry mortar, plaster, or bedding
- Sand volume calculated using mix ratio applied to dry volume
- Bulking factor applied if sand is measured by volume in damp condition
- Correct bulk density used for volume-to-weight conversion — 1450–1650 kg/m³ for river sand
- Wastage of 5–10% added to calculated sand volume before ordering
✓Sand Quality & Testing+-
- Sand zone confirmed per IS 383 — Zone II or III for concrete, Zone I or II for plaster
- Silt content tested and confirmed below 8% — field jar test performed
- Sand free from organic matter — colour test or smell test performed
- Sand clean and free from clay lumps, mica flakes, and shell fragments
- Confirm sand is river or quarry sand — not sea sand
- Sand moisture content estimated — adjust water content in mix if sand is wet
✓Delivery & Storage+-
- Sand quantity verified at delivery — weigh bridge slip or measured volume checked
- Sand stockpiled on hard, clean surface — not directly on contaminated ground

✓Volume Estimation & Formula+-
- Sand application confirmed — concrete, masonry mortar, plaster, or bedding
- Sand volume calculated using mix ratio applied to dry volume
- Bulking factor applied if sand is measured by volume in damp condition
- Correct bulk density used for volume-to-weight conversion — 1450–1650 kg/m³ for river sand
- Wastage of 5–10% added to calculated sand volume before ordering
- Sand quantities calculated separately for each application — concrete and mortar not combined
- Final sand volume expressed in m³ — converted to loads or tonnes for supplier
✓Sand Quality & Testing+-
- Sand zone confirmed per IS 383 — Zone II or III for concrete, Zone I or II for plaster
- Silt content tested and confirmed below 8% — field jar test performed
- Sand free from organic matter — colour test or smell test performed
- Sand clean and free from clay lumps, mica flakes, and shell fragments
- Confirm sand is river or quarry sand — not sea sand
- Sand moisture content estimated — adjust water content in mix if sand is wet
- Sand grading confirmed by sieve analysis if structural concrete is specified
- Visual inspection of delivered sand — colour and particle characteristics consistent
✓Delivery & Storage+-
- Sand quantity verified at delivery — weigh bridge slip or measured volume checked
- Sand stockpiled on hard, clean surface — not directly on contaminated ground
- Sand stockpile covered in monsoon — prevents excessive wetting and silt contamination
- Different sand grades stockpiled separately — concrete sand not mixed with plaster sand
- Sand taken from stockpile starting from the base — not always from the top
