TryBuildCalcLand Leveling Verification Checklist

Essential Checklist+−
Complete these critical checks before approving the work or proceeding to the next construction stage.
✓12 Inspection Points
✓4 Verification Categories
✓Survey and Levels+-
- A grid of spot levels was taken on site using a dumpy level or auto-level — not estimated by eye.
- The benchmark (reference datum) is a permanent, fixed point — not a temporary peg that may be disturbed.
- Spot levels at the plot boundary were taken to confirm the relationship to the road / drain level.
- The proposed finished level (formation level) accounts for drainage slope — minimum 1:100 slope to outfall.
✓Cut and Fill Volumes+-
- Cut volume and fill volume were calculated separately — the net earthwork direction (cut or fill dominant) determines haulage requirements.
- A shrinkage / compaction factor of 10–25% was applied to fill volumes — loose soil occupies more volume than compacted fill.
- A bulking factor of 20–30% was applied to cut volumes when estimating haulage — excavated soil occupies more volume than in-situ soil.
- The balance between cut and fill was checked — excess cut soil requires off-site disposal; fill deficit requires import of material.
✓Equipment and Cost+-
- Number of compaction passes and layer thickness were specified — maximum 200mm loose layers for plate compactor, 300mm for vibratory roller.
- Soil type (clay, silt, sand, rock) was confirmed — it affects compaction method, cost, and fill suitability.
✓Before Work Starts+-
- The finished formation level is above the highest flood level or road level to ensure drainage away from the plot.
- Existing underground services (water, sewer, electricity, telecom) were marked out before excavation begins.

✓Survey and Levels+-
- A grid of spot levels was taken on site using a dumpy level or auto-level — not estimated by eye.
- The benchmark (reference datum) is a permanent, fixed point — not a temporary peg that may be disturbed.
- Grid spacing is appropriate for the site size — 5m × 5m for small plots, 10m × 10m for larger sites.
- Spot levels at the plot boundary were taken to confirm the relationship to the road / drain level.
- The proposed finished level (formation level) accounts for drainage slope — minimum 1:100 slope to outfall.
- Existing trees, structures, and underground utilities were identified before setting the finished level.
✓Cut and Fill Volumes+-
- Cut volume and fill volume were calculated separately — the net earthwork direction (cut or fill dominant) determines haulage requirements.
- A shrinkage / compaction factor of 10–25% was applied to fill volumes — loose soil occupies more volume than compacted fill.
- A bulking factor of 20–30% was applied to cut volumes when estimating haulage — excavated soil occupies more volume than in-situ soil.
- The balance between cut and fill was checked — excess cut soil requires off-site disposal; fill deficit requires import of material.
- Soft or organic topsoil identified in cut zones was excluded from fill material — it is unsuitable as structural fill.
- Fill material source and specification were confirmed — random soil fill without CBR testing is not suitable under structural floors.
✓Equipment and Cost+-
- Equipment selection matches the volume — JCB or tractor for small plots, motor grader and compactor for large areas.
- Number of compaction passes and layer thickness were specified — maximum 200mm loose layers for plate compactor, 300mm for vibratory roller.
- Earthwork rate includes loading, transport, and off-site disposal — not just excavation alone.
- Monsoon and wet season constraints on earthwork were confirmed with the contractor.
- Soil type (clay, silt, sand, rock) was confirmed — it affects compaction method, cost, and fill suitability.
- Delivery charges for imported fill material were confirmed separately from the levelling cost.
✓Before Work Starts+-
- The finished formation level is above the highest flood level or road level to ensure drainage away from the plot.
- Existing underground services (water, sewer, electricity, telecom) were marked out before excavation begins.
- Topsoil stripping depth (150–300mm) was accounted for — stripped topsoil is stockpiled separately, not mixed with fill.
- A soil test or bore log was reviewed to identify black cotton soil, expansive clay, or other problematic strata.
