Foundation Footing Quality Check Procedure
Standard operating procedure for footing construction ensuring structural integrity, durability, and serviceability through proper inspection and testing methods in accordance with Indian Standards (IS Codes).
Structure Type: RCC Footing
Quality Priority: High
Validity: All Projects
To establish a comprehensive quality control procedure for Foundation Footing Construction, ensuring structural integrity, load-bearing capacity, and durability through proper inspection and testing methods in accordance with Indian Standards (IS Codes).
- Verify soil bearing capacity matches structural design assumptions
- Check ground water table level and dewatering requirements if any
- Ensure site is cleared of vegetation, organic materials, and debris
- Verify soil compaction if done and test results are available
- Check drainage provisions around foundation area
IS 1904:2019
IS 1498:1970
- Verify center lines, grid lines and reference benchmarks
- Check footing dimensions and locations as per approved drawings
- Ensure proper marking of excavation boundaries
- Verify levels and reduced levels (RL) of foundation base
- Check diagonal measurements to ensure rectangularity
IS 1904:2019
IS 962:1989
- Verify excavation depth matches foundation design requirements
- Ensure proper slope/shoring to prevent cave-ins as per IS 3764
- Check excavation base is level, firm, and free from loose soil
- Verify dewatering arrangements if groundwater is encountered
- Ensure safety provisions for workers in deep excavations
IS 3764:1992
IS 1904:2019
- Verify PCC mix ratio (typically 1:4:8 or 1:3:6) as per design
- Check thickness of PCC (minimum 75-100mm)
- Ensure PCC extends beyond footing dimensions (50-75mm on all sides)
- Verify level and compaction of PCC surface
- Check curing of PCC layer for minimum 24-48 hours
IS 456:2000
- Verify formwork dimensions match structural drawings
- Ensure formwork is rigid, properly supported, and leak-proof
- Check proper application of form release agent/oil
- Verify cleanliness of formwork (free from debris, dust, water)
- Ensure proper alignment and verticality of formwork sides
- Check stepped/sloped footing formwork if applicable
IS 14687:1999
IS 456:2000
- Verify bar size, spacing, and positioning as per structural drawings
- Check for proper placement of bottom and top reinforcement mats
- Ensure adequate concrete cover using appropriate spacers/chairs (minimum 50mm at bottom)
- Verify proper lap length for bar splices (if any)
- Check dowel bars for columns are properly positioned and secured
- Ensure reinforcement is free from mud, oil, paint, loose rust
- Verify development length of column dowel bars into footing
IS 456:2000
IS 2502:1963
IS 1786:2008
- Verify concrete grade (typically M20 or M25) as per design
- Check for admixtures if required (waterproofing, workability)
- Conduct slump test (recommended slump 75-100mm)
- Ensure proper pouring sequence and method (avoid segregation)
- Check for proper compaction using vibrators
- Verify concrete cube samples are taken for testing
- Check final level of concrete matches required top of footing level
IS 10262:2019
IS 456:2000
IS 1199:1959
- Verify waterproofing material specifications if needed
- Check application of waterproofing agents in the concrete mix
- Ensure external waterproofing membrane is properly applied
- Verify all construction joints are properly treated
- Check for proper termination of waterproofing at ground level
