This method statement must be signed off by all key stakeholders before work begins. Any deviation from this statement during the operation requires a formal revision and re-approval by the Lifting Engineer.

A successful dismantling operation requires a clearly defined command structure. The following key personnel must be appointed and present on-site:
Responsible for lifting and lowering the dismantled sections safely to the ground. Communication Protocol
Operates the assist crane used to lower the tower crane components. Assemble the required boom and fly jib combination;
Tower cranes are commonly used in construction sites to lift and move heavy loads. However, when a construction project is completed, the tower crane needs to be dismantled and removed from the site. Dismantling a tower crane is a complex process that requires careful planning, specialized equipment, and trained personnel. This method statement outlines the steps and procedures for safely dismantling a tower crane.
A comprehensive Job Safety Analysis (JSA) must be reviewed with the entire team. The Lifting Supervisor will explain the sequence of steps, individual roles, emergency protocols, and specific hazards like trapped fingers, falling objects, and high winds. 2. Exclusion Zones and Public Safety
Fully extend the outriggers onto heavy-duty timber or steel spreader mats to distribute the ground pressure.
Remains on-site throughout the entire operation to supervise the rigging crew and ensure the lift plan is strictly followed. This method statement must be signed off by
Establish a strict exclusion zone at ground level using physical barricades and warning signs.
Remove structural wall ties sequentially as the mast height drops. Never remove a tie section below the unbraced height limit specified by the manufacturer. Step 5.7: Base/Fixing Angle Disassembly
Certified technicians responsible for unbolting components, attaching slings, and securing loads.
This section provides a clear description of the crane being dismantled (make, model, serial number) and the site's layout. It notes the crane’s height, jib length, and proximity to neighboring buildings, power lines, and pedestrian walkways. 2. Responsibilities and Roles
