The Cape Bridgewater Wind Farm is an innovative renewable energy project located on the scenic headland of Cape Bridgewater in Western Victoria. It consists of 29 strategically positioned wind turbines, each with towers reaching a height of 67 metres and equipped with blades measuring 33 metres in length. Each turbine tower is securely anchored to a substantial pad footing, approximately 14 metres in diameter and positioned roughly 3 metres below ground level.
Geologically, the site predominantly features dune sands originating from regional limestone deposits. During preliminary investigations conducted by URS, it was determined that ten out of the twenty-nine turbine sites required specialised ground improvement solutions to ensure foundation stability.
Dynamic Compaction (DC) was selected as the most effective and practical method for ground improvement at these locations. Menard Oceania was subsequently contracted by the local foundation works provider to design and execute the Dynamic Compaction program. This process involved compacting the ground to depths ranging from 3 metres up to 10 metres below the proposed foundation levels.
Utilising a robust 17-tonne pounder, Menard successfully completed the ground improvement works, customising the Dynamic Compaction specifications to meet the varied depth requirements across different turbine sites. This tailored approach ensured optimal stability and structural integrity for the wind turbines, supporting their long-term operational efficiency and safety.
