The stability of the jacking machine must be verified, especially on soft ground. Specialist builders must maintain high-capacity rigs; for example, G3 category specialists require rigs with a minimum 400-ton counterweight .
Effective measures, such as warning signs and restricted access, must be implemented to keep personnel away from the test area while loading is in progress. The stability of the jacking machine must be
The Geotechnical Society of Singapore ( GeoSS ) has established specific guidelines for the installation of jacked foundation piles to ensure structural safety and serviceability within Singapore’s unique geological landscape. Jacked piles are favored in urban areas due to their , negligible vibration , and minimal soil disposal . 1. Pre-Installation and Ground Considerations The Geotechnical Society of Singapore ( GeoSS )
After installation, tests like Sonic Logging , PDA/PIT , or Full Coring are used to assess the structural integrity of the piles. 5. Performance-Based Design tests like Sonic Logging
Successful installation begins with a thorough understanding of the site’s soil profile to prevent damage to adjacent structures.
GeoSS recommends achieving two consistent sets before termination.
