Geoss Good Practice For Installation Of Jacked Foundation Piles In Singapore Fix | HOT |

Jacked piling has over 20 years of history in Singapore, evolving from small-scale underpinning to supporting high-rise structures. It is favored for being vibration-free, air pollution-free, and generating low noise levels, making it ideal for urban infill sites. Modern jacking machines in the local market now reach capacities of up to . 2. Machine Capacity and Operational Limits

The proximity of jacked piling to existing infrastructure requires comprehensive risk management protocols.

than the approved plan, the designer must submit an amendment plan and may require additional load tests to verify capacity. Protective Measures for Adjacent Structures Jacked piling has over 20 years of history

Jacked piles are displacement piles —they squeeze soil sideways, which can uplift previously installed piles (especially in marine clay).

Singapore’s dense urban environment, coupled with its variable subsurface conditions (soft marine clay, old alluvium, and granite formations), demands precise, low-disturbance foundation solutions. Jacked piling—hydraulically pushing prefabricated concrete or steel piles into the ground—has become a preferred method for residential, commercial, and infrastructure projects due to its low noise, minimal vibration, and controlled load application. Protective Measures for Adjacent Structures Jacked piles are

The installation process must comply with and specific local good practices.

When connecting prefabricated pile segments, welding must be executed by certified welders. and granite formations)

: A "set" is achieved when the downward movement of the pile does not exceed under the full jacking force, held for at least 30 seconds Verification

Pile testing must be conducted under the direct supervision of a designated person .
