| S.No. | Field / Checkpoint | Reference | Status |
|---|---|---|---|
| A. RAFT POUR DETAILS | |||
| A1 | Raft / mat reference + dimensions (L × B × D) Acceptance: Massive pour planning needed | Per foundation drawing | OK NC NA |
| A2 | Total concrete volume (often 100-500 m³ for large rafts) Acceptance: Volume + sequence documented | Sequence + heat of hydration management | OK NC NA |
| A3 | Mass-concrete consideration if depth > 1m (low-heat cement?) Acceptance: Cooling measures if needed | IS 7861 for mass concrete | OK NC NA |
| B. POURING PLAN | |||
| B1 | Pour sequence — strips or staircase pattern Acceptance: Plan + chart prepared | Adjacent strips poured after first set | OK NC NA |
| B2 | Construction joint location (every 5-7m typical) Acceptance: Treated per IS 456 Cl. 13.4 | Per design | OK NC NA |
| B3 | Concrete supply rate — continuous trucks Acceptance: Schedule confirmed with batch plant | 1 truck per 15-20 mins typical | OK NC NA |
| C. TEMPERATURE + CURING | |||
| C1 | Concrete temperature on placement (< 32°C ideal) Acceptance: Measured each truck | IS 7861 for mass concrete | OK NC NA |
| C2 | Internal temperature monitoring (every 6 hrs) Acceptance: Thermal cracking prevention | ΔT centre-to-surface < 20°C | OK NC NA |
| C3 | Wet curing 14-21 days for mass pour Acceptance: Continuous moisture | IS 456 Cl. 13.5 + IS 7861 | OK NC NA |
