Without a written, approved, and briefed method statement, tower crane dismantling is illegal on most regulated sites. But beyond compliance, the document serves three real-world purposes: Assumption: dismantling a luffing or hammerhead tower crane

After the last component is on the ground: Note: Provide a detailed engineered lift plan with

| Condition | Action | |-----------|--------| | Wind speed > 20 mph (9 m/s) | Stop all lifts above 50ft height. | | Wind speed > 25 mph (11 m/s) | Complete stop – secure partial load. | | Rain / fog (visibility < 50m) | Stop work. | | Lightning within 10 miles | Stop work, evacuate crane area. | | Night work | Only permitted with full lighting (500 lux minimum). |

Even with a method statement, crews sometimes deviate. Watch for these errors:
