| ACTIVITIES. Inspection & Test Planning Matrix | |||
| COL_01 | S.No Acceptance: Sequential, no gaps or duplicates | Sequential numbering of activities in ITP | |
| COL_02 | Activity / Work Stage Acceptance: Specific activity name, e.g., 'Concrete Pouring — Foundation Slab', 'Steel Erection — Beam Installation', 'Plumbing Installation — Roughing' | Clear identification of construction activity | |
| COL_03 | IS Code Reference Acceptance: e.g., 'IS 456:2000 Clause 6.3', 'IS 875:1987 Part 3', 'IS 3786:1983', Code and clause number both specified | Link activity to applicable IS standard / code / clause | |
| COL_04 | Inspection / Test Description Acceptance: e.g., 'Visual inspection of surface finish (flatness)', 'Dimensional check — thickness tolerance ±5mm', 'Concrete compression test @ 28 days', 'Hydrostatic pressure test @ 1.5 × working pressure' | Specific inspection or test to be performed | |
| COL_05 | Acceptance Criteria Acceptance: e.g., 'Surface level ≤ 3mm variation in 3m straightedge', 'Compressive strength ≥ 30 MPa (3 cube average)', 'Slump 100±25mm', 'No visible cracks', 'Joint width = 20±2mm' | Quantified pass/fail criteria for each inspection/test | |
| COL_06 | Inspection Level (H/W/R) Acceptance: H (Hold Point) = Work must STOP, awaits signature. W (Witness Point) = Consultant/Client invited, work CAN proceed. R (Review) = Document review only, no site witness needed | Classification of inspection point approval requirement | |
| COL_07 | Frequency / Quantity Acceptance: e.g., '100% visual', 'Every 50m³ concrete', 'Daily', 'Per 10 units produced', '3 cubes per batch' | How often or how many inspections per activity | |
| COL_08 | Responsibility (Contractor / Consultant / Client) Acceptance: Contractor = Contractor's own QC team. Consultant = Independent consultant's QC engineer. Client = Client representative. Can be combined, e.g., 'Contractor & Consultant' | Who performs the inspection / test | |
| COL_09 | Reference Document Acceptance: e.g., 'IS 1199:1959 (Concrete compression test)', 'IS 1123:1959 (Slump test)', 'Method Statement MS-04-Concrete', 'Test Report TR-025', Document reference number and title | Link to applicable test method, procedure, or standard document | |
| COL_10 | Remarks / Special Instructions Acceptance: e.g., 'Test lab accredited to IS 1200', 'Witness by Client Engr. Shri X', 'Repeat if NC found', 'Weather conditions: Temp 15-30°C' | Any additional notes or conditions for this inspection | |
| LEGEND. ITP Approval Level Legend | |||
| LEGEND_H | H = HOLD POINT Acceptance: Work STOPS. Inspection/test completed and documented. Must be signed off by authorized party (Consultant/Client QC engineer). Non-Conformance stops work immediately. Corrective action required. Work can ONLY proceed after hold point is released (signed off). | Mandatory approval before work proceeds | |
| LEGEND_W | W = WITNESS POINT Acceptance: Consultant / Client invited to witness inspection/test. Contractor's QC conducts test. Work CAN proceed if results are OK, even if witness is not present. Witness is optional but logged. Non-Conformance becomes Hold Point. | Invited observation point (work can proceed if inspection OK) | |
| LEGEND_R | R = REVIEW POINT Acceptance: Inspection/test completed and documented. No site witness required. Consultant/Client reviews document (test report, inspection record). Review can happen later. Work proceeds as per schedule. Used for routine inspections and lab test reports. | Document review only, no site presence required | |
