PROJECT DESCRIPTION

A mixed-use development comprising a 49-storey residential apartment block, a 40-storey commercial tower and a 5-star hotel. Special aspects included large blocks of cantilevered floors, large transfer structures and partial top-down construction of basements.

Judge's comment:

The resolution of variable form and load paths in this project demonstrates the ability of the structural engineer to take many different design challenges and resolve them into an apparently simple and buildable form. The two towers present large blocks of cantilevered floors at height. The resulting transfer of vertical load path impacted design and detailing for both the long term permanent structural behaviour as well as considerations for construction. Load balancing of the cantilevers at the cores as well as the connection detailing presented challenges for the engineers which were resolved through careful consideration and early involvement with the contractor.
