Essential Checklist+−
Complete these critical checks before approving the work or proceeding to the next construction stage.
✓16 Inspection Points
✓3 Verification Categories
✓Calculation Inputs & Formula Verification+-
- Concrete volume calculated from actual site dimensions — not drawing dimensions
- Dry volume factor of 1.54 applied — result is approximately 54% larger than wet volume
- Cement fraction extracted using full denominator — total of all mix parts
- Cement volume converted to bags correctly — 1 bag (50 kg) = 0.0347 m³
- Wastage percentage added before finalising cement quantity
- Cement requirement calculated for full pour session — not just one element
- Concrete grade and nominal mix ratio confirmed from structural drawing for each element
- Water-cement ratio verified — does not exceed IS 456:2000 limits for exposure class
- Minimum cement content per IS 456:2000 met — 300 kg/m³ for M20 moderate exposure
✓Mix Water & Admixtures+-
- Mixing water is potable or tested and confirmed suitable — no sea water or sulphate-contaminated water
- Water quantity measured — not added by estimation or hose
- If admixture used — compatibility with cement type confirmed and dosage per data sheet
- No additional water added to concrete at placement point to improve workability
✓Site Batching & Quality Control+-
- Materials batched by weight — not by shovel count or uncontrolled gauge boxes
- Mixing time adequate — minimum 1.5 minutes in drum mixer after all materials added
- Cube test samples cast from every pour — minimum 3 cubes per 30 m³ or per element

- Cube test samples cast from every pour — minimum 3 cubes per 30 m³ or per element
- RMC delivery challan verified — grade, w/c ratio, batch time, and admixture confirmed
- Pour record maintained — cement bags used, water added, admixture dose, slump result
