Garden Island Naval Base Wharf Upgrade

Bonacci Infrastructure delivered the construction engineering, methodology and temporary works designs for the wharf upgrade at the Garden Island Naval Base.

Client: Georgiou Brady Joint Venture
Location: Sydney, New South Wales, Australia

Part of the wharf upgrade at the Garden Island Naval Base included the construction of a contiguous piled wall running along the entire wharf perimeter. The perimeter distance was approximately 460m and involved the installation of approximately 700 piles. The tolerance for the position of the piles on the perimeter wall was very tight to facilitate their connection with the precast concrete capping beam installed above.

Bonacci Infrastructure provided a piling gate solution for the Georgiou Brady Joint Venture that ensured the positional tolerance could be met reliably and piles installed rapidly. Each gate setup allowed for the installation of 12 piles. A leapfrogging support system for the gate was also designed to further ensure that piling production rates could be maximized.

 

Other services provided were piling stability analyses for a variety of geotechnical and load scenarios, and a temporary bracing system to ensure that the works could be installed safely and without damage due to loads that may be applied during construction.
