Turnkey Site QA/QC Inspection Protocol

Critical field checkpoints before casting, during concreting, and post-curing

✓
Pre-Pouring Shuttering & Reinforcement Check
Verify formwork line, level, and plumb. Inspect PVC/mortar cover blocks (never marble/stone pieces). Verify electrical conduits and plumbing sleeves are tied prior to casting.
✓
Transit Slump Cone Test (IS 1199)
Permissible slump: 75 mm to 100 mm for manually poured concrete; 100 mm to 125 mm for pumpable RMC mix. Strictly prohibit drivers or labor from adding site water.
✓
Compressive Concrete Cube Testing (IS 516)
Minimum 6 cubes (150×150×150mm) cast per 15 m³ batch. 3 cubes crushed at 7 days (≥67% strength), 3 cubes tested at 28 days (≥100% design strength) in NABL lab.
✓
72-Hour Sunk Slab Water Ponding Test
Fill 2 inches of water in all bathroom sunken portions, kitchen utility, and terrace slabs. Inspect underside for dampness or seepage before tiling or plumbing concealment.
✓
Crack-Arresting Wire Mesh on Masonry Joints
Fix 150mm wide GI chicken wire mesh or fibreglass mesh across all RCC column/beam to brickwork joints prior to internal and external plastering.
