The hydraulic pressure gauge provides an immediate record of the installation force at every depth. 2. Pre-Installation Requirements and Site Investigation
The pile's verticality must be checked throughout the process.
For jacked piles specifically, the jacking machine itself can be treated as “mobile kentledge” for static load testing, allowing proof-testing to a load level equal to the maximum applied jacking force. The hydraulic pressure gauge provides an immediate record

GEOSS Good Practice for Installation of Jacked Foundation Piles in Singapore Introduction For jacked piles specifically, the jacking machine itself
The Geotechnical Society of Singapore (GeoSS) has established guidelines for the , focusing on ensuring structural integrity and minimizing ground disturbance in Singapore's diverse geological conditions. Key Good Practices for Installation
Because every single pile is pushed to a multiple of its design load during installation, the jacking rig acts as an individual proof-tester, reducing structural performance uncertainty. To help tailor this guide further, let me know: Key Good Practices for Installation Because every single
Ground Penetrating Radar (GPR) and trial pits must locate adjacent services.
: If a pile penetrates through a consolidating soft clay layer (such as the Upper Marine Clay of the Kallang Formation ), the long-term downdrag force will act as negative skin friction. This reversal of force direction must be explicitly factored into the magnitude of the jacking load ( Pjcap P sub j ) during installation. Comprehensive Site Investigation (SI)
For precast concrete or spun piles, mechanical joints or full-penetration butt welding of steel end plates are used.
