Total of 1,224 CFA piles of varying diameters, including 296 deep foundation piles and 938 are secant retention piles
420m of guide walls installed with the support of poly foam
87 piles designed to a drill depth of approximately 36m
Key Challenges
Loose and very soft layers of Crude Island Silt materially increased risk of concrete washout and soil intrusion between newly installed piles, making pile sequencing a critical consideration in the construction process
Located in the heart of Melbourne CBD, the site itself posed logistical difficulties. Every stage of construction, from service relocation to material deliveries, required careful planning and coordination. Access constraints and limited working space further compounded these challenges
