Bonacci Infrastructure delivered the construction engineering, methodology and temporary works designs for the wharf upgrade at the Garden Island Naval Base.
The upgrade included a contiguous pile wall along the entire wharf perimeter and involved the installation of approximately 700 piles over a distance of approximately 460 metres. The positional tolerances for piles on the perimeter wall were very tight to facilitate their connection to the precast concrete capping beam installed above.
Bonacci Infrastructure designed a piling gate solution for the Georgiou Brady Joint Venture (GBJV) that allowed large numbers of piles to be installed rapidly and reliably within specified tolerances. Each gate setup allowed twelve piles to be driven in one operation, with a leap-frogging support system maximising installation rates for subsequent setups.
Bonacci Infrastructure also performed pile stability analyses for a variety of geotechnical and loading scenarios and delivered a temporary bracing system that ensured the works could be installed safely and without damage from construction loading.
