Complete these critical checks before approving the work or proceeding to the next construction stage.
✓10 Inspection Points
✓2 Verification Categories
✓Calculation Inputs & Formula+-
- Bar diameter confirmed from structural drawing — not assumed
- Unit weight calculated using D²/162 formula — not from memory or approximation
- Total bar length includes all hooks, laps, and anchorage extensions
- Number of bars of each diameter confirmed — not estimated
- Weight calculated for all structural members — no member omitted
- Wastage of 3–5% added to calculated weight before ordering
- Standard rod length of 12m used for rod count — confirmed with supplier
✓Procurement & Delivery Verification+-
- Weight verified at weigh bridge — delivery challan weight matches ordered quantity
- Delivered diameters checked using bar gauge — all diameters confirmed correct
- Mill test certificate received for all consignments — grade and test values verified

✓Procurement & Delivery Verification+-
- Weight verified at weigh bridge — delivery challan weight matches ordered quantity
- Delivered diameters checked using bar gauge — all diameters confirmed correct
- Mill test certificate received for all consignments — grade and test values verified
- Cost verified — rate per tonne as agreed, applied to delivered weight
- Delivered quantity checked against BBS requirement plus wastage
