5. Step-by-Step Visual SOP

Take photo of vehicle and material before unloading. [PHOTO: Vehicle + material]
Check for stones, roots, plastic, waste or contamination. [PHOTO: Wrong example]
Check whether soil is too wet by hand test.
Do not mix wet soil with dry soil.
Unload only in the marked red soil zone. [PHOTO: Correct zone]
If material is wet/contaminated, keep separate and inform management.
Record supplier, quantity, date and status.

6. Do / Don't

✅ Do	❌ Don't
Take photo before unloading	Unload in the m-sand area
Keep wet and dry soil separate	Mix old and new material without approval
Use the marked red soil zone	Use wet soil without approval
Inform if quality is doubtful	Accept contaminated material silently

7. Checklist

[ ] Supplier identified
[ ] Quantity noted
[ ] Photo taken
[ ] Moisture checked

8. Records To Update

🔵 Raw material receipt register

9. Escalation Rule

Inform Ram/Srinivasan if: soil is wet, soil has stones/waste, quantity is doubtful, or supplier quality is poor.

10. Common Mistakes

Unloading before photographing the load.
Mixing a wet load into the existing dry heap.
Recording quantity by guess instead of checking.
