Port Adelaide Grain Berth Wharf, SA
Duration: November 2004 to January 2006
Value: $17 million
Contract type: Lump Sum
Summary: Built Environs delivered the Port Adelaide Grain Berth project in the Adelaide suburb of Outer Harbour.
The 226-metre-by-37.5-metre wharf easily accommodates extremely large (100,000 tonne-plus) Cape-size bulk carriers and includes a 320-metre-long, 1.2-metre-thick rock revetment, pavement, an amenities building and wharf services.A 500-tonne onshore crane and floating barge rig eliminated the need for a second, barge-mounted crane and saved considerable money and time.
To minimise the amount of over-water work, beams were formed from large prefabricated steel shutters, spanned between piles and supported by columns cast into pile plugs, while the slab formwork was stripped above the deck and floated beneath the wharf between pours.
Reinforcing for beams was tied on shore and craned into position as a prefabricated cage, saving time with concrete pouring and improving safety by significantly reducing the time spent tying reinforcing above water.
Well-managed relationships and clear communication contributed to the successful delivery of a complex and challenging project.
The Built Environs engineering capability that delivered this project is now provided by the South Australian engineering office of parent company McConnell Dowell, offering clients access to both the expertise of the former Built Environs engineering teams and the international experience of McConnell Dowell.
