Australian Marine Complex Vessel Transfer Path— $61m CIVIL, DIGITAL ENGINEERING, ELECTRICAL, GEOTECHNICAL, HEAVY LIFTING AND PAVEMENTS
Located in Western Australia, 23km south of Perth, the 400ha Australian Marine Complex provides services for the repair, maintenance and construction of naval and commercial vessels, as well as infrastructure for the fabrication and assembly of offshore oil and gas modules. The Vessel Transfer Path Upgrade project allowed for the transport of larger vessels between the Common User Facility floating dock and the Civmec Shipbuilding Facility all within the Australian Marine Complex.
HEAVY INDUSTRIAL PAVEMENT DESIGN
The road design required a width of 19m and clearances of 25m, with a consistent longitudinal gradient of under 2% to ensure safe passage for the self-propelled modular transporters. To accommodate the 15t wheel loads, 1400kPa tyre pressures, and speeds of 1km/h, the pavement had to meet heavy industrial pavement standards, with a design life of 20 years. Geotechnical investigations revealed the need for high-quality crushed igneous rock in the top 100mm of the base course to create a tightly bound surface for sealing. WGA optimised the pavement design to minimise the initial cost while reusing as much existing pavement material as possible, utilising an adaptive design based on results of in-situ testing during construction.
