Based in Port Macquarie, Birdon confirmed its split hopper barge “PELICAN” and backhoe dredge “BHD SYDNEY” have now arrived at Garden Island, and are ready to commence dredging works.
The company said it is "proud to be part of improving Australia’s Defence Force capabilities" in a release, and said that the dredging works will increase the depth of the berth pocket for naval vessels at Garden Island as part of an upgraded wharf infrastructure project.
It will include the supply, maintenance and operation of all equipment for the removal and disposal of a significant volume of dredged material from Sydney Harbour, using equipment tailored for operation in the local conditions, Birdon confirmed.
The work represents element three of stage two of the Garden Island Redevelopment Project, with Lendlease winning the $286 million contract to the second stage.
The elements of the project are as follows:
- Project Element 1: Demolition of wharf structures;
- Project Element 2: Construction of wharf structures;
- Project Element 3: Seabed dredging;
- Project Element 4: Wharf furniture;
- Project Element 5: Portal crane; and
