ACAA 2018 Winner: Optus Stadium and Stadium Park
In the construction of Optus Stadium and the surrounding Stadium Park, Multiplex has delivered a truly world-class venue for Western Australia.
Located on the Burswood Peninsula, the 60,000 seat multi-purpose Stadium can host a variety of sports and entertainment events including Australian Football League, cricket, soccer, rugby and concerts.
The surrounding Stadium Park provides year-round access for visitors of all ages, with facilities including nature playgrounds in the Chevron Parkland, the BHP Boardwalk and Amphitheatre, picnic and barbeque areas, public art, recreational facilities and bars and restaurants.
Multiplex was responsible for the design and construction of the Stadium and Stadium Park as part of the Westadium Consortium, appointed by the Western Australian State Government in 2014 using a Design-Build-Finance-Maintain (DBFM) procurement model to deliver the project.
The consortium comprises John Laing (the equity investor and asset manager), Multiplex (the lead design and construction contractor), BGIS (the facilities manager leading the maintenance and services delivery), and Brookfield Financial (the financial adviser).
With a ‘fans first’ philosophy guiding the Stadium design, Multiplex managed and coordinated the design consultant team to interpret the project brief and develop a compliant and coordinated design solution with buildability input.
The result is an innovative design which delivers an unrivalled stadium experience for Western Australia.
The Stadium itself is a six-level steel and concrete structure with a colosseum seating bowl designed to bring fans closer to the action. A lightweight fabric roof covers 85% of seats and creates a suspended ‘halo’ effect owing to an innovative roof truss design.
The structure is clad with a striking anodised aluminium façade reflecting WA’s unique geology.
Stadium facilities include over 50 food and beverage options and 17 premium product areas – the largest variety of any stadium in Australia.
With a vision of a ‘Stadium within a park’, Multiplex’s scope of work also consisted of hard and soft landscaping over an area of 41 hectares.
Ground conditions for the project were particularly challenging due to previous land uses of the Burswood Peninsula, with a number of innovative ground improvement and ground gas mitigation techniques used to successfully rehabilitate the area.
Other challenges included the development of a delayed design and procurement program to incorporate the operator’s requirements and ensure the latest technology was available at the Stadium opening. This includes the world’s largest LED integrated sports lighting system and two 340m2 mega screens – now the biggest sport screens in the southern hemisphere.
In total, Multiplex engaged more than 150 subcontractors, consultants and suppliers to deliver the full range of trades and services, with the project’s daily workforce reaching over 1,350 at peak.
Over 8,000 people were inducted over the life of the project and 4.2 million man-hours achieved with no significant injuries.
Construction started in December 2014 and the project was completed three weeks ahead of schedule in November 2017.
With a key target being to open the Stadium in time for the 2018 AFL season, Multiplex’s early delivery of the project allowed Optus Stadium and Stadium Park to open ahead of schedule on 21 January 2018.
