PROJECT DESCRIPTION

With a height of 528m, this 108-storey tower is possibly the world’s tallest building constructed in a high seismic zone. A gently rising and curving profile gives the building a contemporary and elegant expression, accommodates more prime-floor spaces at the top levels and provides structural stability at the base.  

 

 

 

 

Judge's comment:

The judges were impressed with the multi-faceted structural design for an extremely tall and slender building in a high seismic zone.  

Using parametric design, hundreds of potential solutions were explored. The tower employs a multiple lateral load resisting system with a central concrete core and a perimeter mega-frame. The external mega-frame is built from concrete-filled steel box sections. Belt trusses at mechanical/refuge floors provide further stability. 

An intelligent construction approach was developed using an integrated platform – a steel frame structure set on the top of the concrete core that was jacked up as work progressed. This multi-level construction platform saved time and cost of conventional cranes and provided a work-place in the sky. 

With its challenging form (widening towards the top), challenging location (high seismic conditions) and extreme height (528m), this tall tower presented multiple challenges to its structural engineers. They developed a design that combines well-known systems in an intelligent way, including an innovate means of construction.
