Phase 1: Pre-Planning & Site Survey
Gather essential project information and conduct site assessment
Project Information
Ground Conditions (M5)
Site Survey Checklist
Ground Conditions
Proximity Hazards
Access/Egress
Phase 2: Load Calculations
Calculate load weights, COG, and lifting accessories
🧮 Load Weight Calculator (M9)
Calculate weight of cylindrical steel objects (tubes, pipes, bars)
- Cross-sectional Area = π × [(OD/2)² - (ID/2)²]
- Volume = Area × Length
- Mass per item = Volume × Density
- Total Load = Quantity × Mass per item
📐 Centre of Gravity (COG) Determination (M10)
📏 Lift Parameters
🔗 Lifting Accessories
Phase 3: Crane Selection & Ground Bearing
Select appropriate crane and verify ground bearing pressure
🏗️ Crane Details
⚖️ Ground Bearing Pressure Calculator
Verify ground can support crane + load without settlement
✅ Capacity Verification
Phase 4: Lifting Plan Diagram
Create scale drawing with crane position and hazards

Phase 5: Risk Assessment
Identify hazards and define control measures (M24-M26)
⚠️ Hazard Identification & Risk Matrix
| Hazard | L × S | Risk | Control Measures | Action |
|---|---|---|---|---|
| 25 | EXTREME | |||
| 16 | HIGH | |||
| 12 | MEDIUM |
📊 Risk Matrix Guide
Likelihood 5 × Severity 5
STOP - Cannot proceed
Requires senior approval
