Port Botany Container Terminal Expansion
Project Overview
The Port Botany Container Terminal Expansion was a major project in Sydney, Australia, involving the reclamation of 63Ha using 8 million m³ of dredged sand. The project included the construction of a new container terminal, additional berth length, and public facilities.
Landpac's Solution
Landpac’s High Energy Impact Compaction (HEIC) was deployed to enhance the soil’s bearing characteristics in the top 2.0m of the soil profile, where previous Vibro compaction methods had shown limitations.
Challenges
The expansion faced geotechnical challenges due to the soil conditions of the reclaimed area, comprising fine to medium-grained marine sands with varying organic and clay content. Achieving the required soil compaction and stability was crucial for the infrastructure’s durability, including high counterfort walls and terminal areas.
Application of HEIC
Soil Compaction: HEIC was used to compact the dredged sands to meet the specified density and cone resistance requirements.
Infrastructure Support: The compaction ensured stable foundations for the new terminal, berths, and public facilities.
Benefits
Improved Soil Stability: The HEIC technique effectively increased the soil’s bearing capacity, essential for supporting heavy structures and operational loads.
Consistent Compaction Results: Monitoring and verification through Landpac’s systems confirmed uniform compaction and adherence to specifications.
Monitoring & Verification
Regular monitoring with Landpac’s soil response and continuous induced settlement systems, along with Density and CPT testing, verified the effectiveness of HEIC.
Landpac’s innovative HEIC approach was instrumental in ensuring the Port Botany expansion met its engineering and operational goals, showcasing the effectiveness of HEIC in large-scale maritime infrastructure projects.
