| S.No. | Field / Checkpoint | Reference | Status |
|---|---|---|---|
| A. TEST SETUP | |||
| A1 | Test pit + dimensions + depth (typically at foundation level) Acceptance: Per spec | Per IS 1888 | OK NC NA |
| A2 | Loading plate — 300mm or 600mm square, 25mm thick steel Acceptance: Per code | IS 1888 Cl. 3 | OK NC NA |
| A3 | Loading mechanism — kentledge + jacks (capacity ≥ test load × 2) Acceptance: Calibrated | Per IS 1888 | OK NC NA |
| A4 | Dial gauges (4 nos.) + reference beam Acceptance: Calibrated | 0.01mm precision | OK NC NA |
| B. LOAD INCREMENTS | |||
| B1 | Initial seating load — 10-20% of expected ultimate Acceptance: Per spec | Per IS 1888 | OK NC NA |
| B2 | Load increments — typically 5 increments to design load + 50% Acceptance: Per test | IS 1888 | OK NC NA |
| B3 | Settlement readings — every 5-10 min until ≤ 0.02 mm/min Acceptance: Per code | IS 1888 Cl. 7 | OK NC NA |
| B4 | Load held until settlement stable Acceptance: Per device | Per IS 1888 | OK NC NA |
| C. RESULTS + INTERPRETATION | |||
| C1 | Load-settlement curve plotted Acceptance: Plotted | Per test | OK NC NA |
| C2 | Ultimate bearing capacity (load at which curve becomes asymptotic OR settlement = 10% of plate size) Acceptance: Per criteria | IS 1888 Cl. 8 | OK NC NA |
| C3 | Safe bearing capacity = Ultimate / FoS (typically 2.5-3) Acceptance: Per code | Per IS 6403 | OK NC NA |
