MCEC & South Wharf Redeveloment

Multiplex and Probuild (then Contexx) contracted Delta Group to complete civil construction works for $1b development of the Melbourne Convention Centre and South Wharf retail and hospitality precinct.

 
The scope of works included:

• Bulk/detailed excavation works allowing for the construction of reinforced concrete foundations.
• Concrete infrastructure – slab preparation and construction, retention systems and lift core rafts.
• Construction of crane bases.
• Emissions, noise and vibration controls.
• Transport logistics, including traffic management and supervision.
• Site infrastructure – basement stormwater drainage systems.
• Site dewatering.

Situated on the banks of the Yarra River, this project involved an extensive remediation programme to capture and dispose of contaminated soil, as well as to manage geotechnical challenges posed by Coode Island silt. In total, we excavated more than 350,000 cubic metres of spoil across both project sites.

As a key member of the Multiplex led project team, our civil works programme was a critical element in achieving a 6 Green Star environmental rating – a world first – for the Melbourne Convention Centre. Other key achievements included:

• Excavation of 350,000 cubic metres of Coode Island Silt and contaminated spoil.
• Construction of 3,000 sqm of shotcrete batters.
• 1,200 piles, including trimming, as well as more than 600 pile caps and 13 lift rats.
• 35,000 sqm of slab preparation.
• Construction of a 550 lineal metre flood wall and 3,000m of basement stormwater drainage.
• Full site (and soil) remediation.
