Project Description

The Perth Arena is Perth`s new multipurpose indoor entertainment an sports venue. The Arena, with a seating capacity of 14,000 incorporates a retractable roof and is designed to attract world class entertainment and sporting events.

It was important to optimise the construction programme, minimise working at heights and save on heavy crane costs. VSL Australia, VSL Switzerland and TCAA joined forces to provide an engineering solution to lift the preassembled retractable roof truss from the ground to its final postion. The roof truss structure comprises two 130m-long "Megatrusses" spaced at 38m and brace togehter support the two halves of the retractable roof. Using the heavy lift method meant all cladding, the retractable roof mechanism and the plant room steelwork could all be installed and tested on the ground.

VSL were commissioned to design and supply a free standing tower system as there was no permanent structure in place for the roof lift.  The 42m high tower system was designed to withstand extreme cyclone conditions common to the region and also to support the roof structure for several months while an additional 800t of permanent columns, bracing and cladding was added.

At the main lift the 2,150t roof truss was lifted 22m within 3 hours as the 8 SLU-580 jacks were supplied by EHPS 2/65 pumps at 65 litres per minute.
