Scope of Work
The demolition work involved:

• Precast Panel Removal: Delsan-A.I.M. removed 464 reinforced concrete panels weighing between 4,500 and 13,500 lbs., located on the concave façades of the tower.
• Glazing Removal: The old curtain wall system was dismantled in preparation for the installation of a new one.

Execution of Work
Use of Tower Cranes
Two tower cranes were installed on either side of the tower to facilitate the removal and replacement of the curtain wall system. These cranes were employed for:

• Rigging and lowering precast panels from the concave façades.
• Transporting dismantled materials safely to ground level.

Custom Lifting Apparatus
To ensure the safe removal of panels, Delsan-A.I.M. deployed specialized, custom-designed lifting equipment that allowed panels to be rigged and removed from inside the tower.

Hoisting Device for Underside Panels
For 80 panels located on the underside of the tower and inaccessible by crane:

• A custom-engineered hoisting device was installed within the tower.
• Panels were lifted internally, transferred to an opening in the façade, and lowered to ground level via one of the tower cranes.

Project Success
Through the use of innovative equipment and meticulous planning, Delsan-A.I.M. completed the removal of precast panels and glazing safely and efficiently, ensuring the iconic tower was ready for its next phase of renovation while maintaining the highest safety standards.
