Phase 1: Pre-Planning & Site Survey

Gather essential project information and conduct site assessment

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)

Formula:
  1. Cross-sectional Area = π × [(OD/2)² - (ID/2)²]
  2. Volume = Area × Length
  3. Mass per item = Volume × Density
  4. Total Load = Quantity × Mass per item

📐 Centre of Gravity (COG) Determination (M10)

✓ For uniform cylindrical load: COG is at geometric center (midpoint of length).

📏 Lift Parameters

⚠️ Critical: Maximum radius is measured from crane slew centre to load COG. Verify with site measurements.

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

⚠️ Abort Criteria: > 25mm settlement observed during 360° slew test = STOP operations immediately.

✅ Capacity Verification

📋 Important: Always verify against manufacturer's load chart. Boom length, jib, and counterweight affect capacity.

Phase 4: Lifting Plan Diagram

Create scale drawing with crane position and hazards

📐 Diagram Dimensions

🎨 Interactive Diagram Builder

Create a professional site diagram using the drawing tools below. Click a tool, then click on the canvas to place objects. Use the Select tool to move objects around.

💡 Tip: Use the drawing tools to create a professional site diagram showing crane position, load locations, exclusion zones, buildings, and overhead hazards. Export as PNG to include in your final plan.

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

EXTREME (20-25):
Likelihood 5 × Severity 5
STOP - Cannot proceed
HIGH (15-19):
Requires senior approval
Enhanced controls needed
MEDIUM (8-14):
Standard controls apply
Monitor during lift
LOW (1-7):
Normal precautions
Proceed with care

Phase 6: Sequence of Operations

Define step-by-step method statement (M27)
