BG&E Buildings

BURSWOOD STADIUM Perth, WA The new Perth Stadium is on the Burswood Peninsula will accommodate 60,000 seats. BG&E was engaged to provide both civil and structural engineering services as part of the services team. The civil design has focused on addressing the existing land conditions of the 73 hectare precinct to reduce the ongoing maintenance of the pavements, roads, in ground services and key landscaped areas; the civil design also recognize the interfaces with the surrounding State Transport Infrastructure to ensure an integrated design approach to the civil and landscaping works. Given the poor ground conditions and associated settlements, all ground slabs are suspended on the piled foundations with all services integrated into the slab using thickenings and service trenches. The stadium superstructure is a steel frame which overall stability is provided by reinforced concrete walls which are configured to match the overall planning of the stadium and coincide with lift shafts, service core and plant rooms that extend through the height of the building. The suspended slabs from level 1 to level 5 have been designed as conventional reinforced concrete slabs cast on Bondek to eliminate the need for propping during construction. The seating plats are precast prestressed concrete elements spanning a double grid (approximately 12m). The seating elements are generally single elements to simplify the pre-casting process and limit the weight for lifting during installation. The structural roof is a three dimensional triangulated steel truss cantilever with a small backspan to minimise roof envelope. Fabric is to be installed to the underside of the trusses which will result in a triangulated open truss to the top. This roof structure was chosen to satisfy the Client’s requirement for a roof system that was prop-free and modulated. BG&E | PAGE 38 PUBL I C BU I LD I NGS
