Manage complex ground conditions using piling solutions from Bridgecon to support efficient and reliable civil construction projects in Melbourne.
Civil construction projects require robust ground support systems that maintain performance across varied geological conditions. Engineered piling solutions deliver reliable load-bearing capacity by aligning the installation method with the site’s soil profile and structural loading requirements.
Analysing CFA and Bored Piles
CFA piling is highly favoured in Australian civil construction for its speed and relatively low noise and vibration. This technique forms a strong pile right in the ground by simultaneously drilling and injecting concrete through the auger. This continuous process makes CFA piling well-suited for soft or wet ground, providing reliable deep foundation support.
Bored piles, also known as drilled shafts, are essential for projects requiring high load capacity, such as large bridges or tall structures. Installation involves digging a shaft, often supported by casing or slurry, before placing steel reinforcement. This technique provides adaptable piling solutions, offering superior flexibility for large diameters in complex ground conditions.
Understanding Driven Pile Characteristics
Driven piles are pre-made structural elements, such as steel or concrete, that are installed by forcing them into the ground with a powerful hammer. This method creates dense soil for strong support and is reliable for sites where maintaining the existing ground structure is important.
Driven pile characteristics:
• Speedy Installation: Piles are ready for immediate load testing after driving, accelerating the construction timeline significantly.
• High Bearing Capacity: The soil surrounding the pile is compacted during installation, increasing friction and load-carrying capacity.
• Quality Control: Each pile’s structural integrity is established before installation, ensuring a consistent, high-quality product.
• Cost Effectiveness: For projects with numerous piles in consistent ground conditions, this technique often proves to be the most economically viable option.
• Minimal Spoil: Since soil is displaced rather than excavated, the volume of waste material needing disposal is significantly reduced.
Matching Piling Solutions to Ground Conditions
The fundamental difference between these methods lies in their installation style. Geotechnical reports provide the necessary data to determine which piling solutions offer the best performance and risk profile for a specific foundation design.
Engineering applications of CFA, bored and driven pile types:
• CFA Piles: Quiet installation and controlled drilling make CFA suitable for vibration-restricted sites and soft or water-affected ground.
• Bored Piles: Large diameters and deeper founding levels enable bored piles to support major structures in complex or layered geological conditions.
• Driven Piles: Immediate load capacity and fast production rates make driven piles effective in marine works and uniform granular soils.
The geotechnical assessment ensures compliance with local standards and best practice construction methodologies, including requirements found in AS 2159 – Piling Design and Installation.
