The roof of the impressive business and entertainment complex adjacent to the International Airport is a highly complex ‘wave’ structure.
Tony Gee was asked to investigate alternate construction methods for roof erection, focusing on time, cost, erection tolerances and interfaces with the other parts of construction. This led on to the design of the detailed erection method, associated temporary works and modifications to the permanent works design.
This included the design of overhead erection gantries which were used to lift roof sub-assemblies to the required level and transport them to their final location, site truss connections and steel reinforced column connections.
The roof comprises primary structural steel trusses supported on a grid of columns with secondary trusses and frames in between.
