Geotechnical Society of Singapore (GeoSS)
The provides essential guidelines for the installation of jacked foundation piles, a method widely favored in urban construction due to its low noise and vibration levels . These "Good Practice" standards ensure structural integrity and geotechnical stability in Singapore's diverse soil conditions, such as the Old Alluvium or soft marine clays. Core Installation Principles
- Handling: Piles (typically reinforced concrete or steel H-sections) must be handled carefully to avoid cracking (for concrete) or bending.
- Splicing (Jointing): The guide outlines good practice for welding splices. Welds must be full-strength and usually inspected using Non-Destructive Testing (NDT), such as Ultrasonic Testing (UT) or radiography, to ensure structural integrity.
