2007 Winner
Southern Cross Station – Melbourne
Leighton Contractors Pty Limited – contract value $420 million.
Construction of Melbourne’s Southern Cross Station took place over, and around, a fully operational transport interchange, which every weekday serviced up to 60,000 commuters travelling on 940 suburban and inter-city trains, as well as connecting bus services.
The main feature of the new station is its spectacular wave-form roof, comprising a series of ‘moguls’ that reach up to 24 metres above platform level. The roof covers an area of 37,000 square metres, including 7,000 square metres of flexible skylights, and is enclosed on all sides by massive glass façades.
The roof utilises passive ventilation technology to extract exhaust fumes from the enclosed space, thereby reducing the station’s power consumption and contribution to carbon emissions.
The project team developed special techniques to prefabricate the roof structure, transport it to site and erect it during night-time track occupations, without causing major disruption to station users. They also created innovative solutions to maintain the structural stability of the partly completed roof and safely install the ceiling and cladding systems.
