The method statement lists all tools and machinery required for the task. This ensures that everything on-site is inspected and fit for purpose:
Specific site address and crane position (e.g., TC1, TC2).
Verify the mobile crane standing area is compacted and capable of bearing the outrigger loads. 5. Step-by-Step Dismantling Procedure Phase A: Preparation tower crane dismantling method statement
The crew climbs the crane, secured by double lanyards to independent anchorage points. The sequence:
| Activity | Hazard | Control Measure | | :--- | :--- | :--- | | Working at height | Fall >10m | Double lanyard harness, static line, scaffold platform if needed. | | Lifting operations | Crane collapse | Lift plan, certified rigging, no side loading. | | Counterweight removal | Crushing | Stay out of line of fire, use tag lines, never walk under suspended load. | | Weather | Swing/sudden gust | Stop work if wind exceeds manufacturer limit (usually 20 mph). | | Electrics | Arc flash/short | Lock-out-tag-out (LOTO) before cutting any cables. | The method statement lists all tools and machinery
The following quality control measures must be implemented during the dismantling process:
Verify the ground bearing capacity for the mobile crane (assist crane). Ensure no new underground utilities or structures have been installed since the crane was erected. Exclusion Zones: | | Lifting operations | Crane collapse |
Note: Provide a detailed engineered lift plan with load calculations for each lift, crane charts and rigging arrangement for every critical lift — attach as appendices.
