Geoss Good Practice For Installation Of Jacked Foundation Piles In Singapore Link ((link)) 〈WORKING • SECRETS〉

It is recommended that the jacking machine be used at no more than 75% of its maximum capacity to ensure safety and equipment longevity.

GEOSS emphasizes real-time monitoring, trigger-level actions, and closed-loop feedback. For jacked piles, this means moving beyond “refusal load” to with continuous data capture. It is recommended that the jacking machine be

: Designers must specify penetration depths based on site investigation (SI) boreholes. However, in Singapore, most specify the jacking force and set criterion on the piling plan as the primary termination metric. Floating Boulders : Designers must specify penetration depths based on

: Piles are typically considered "set" if downward movement does not exceed 10 mm with a minimum holding time of 30 seconds . It is recommended to achieve two consistent sets to ensure stability. Jacking Force ( Pjcap P sub j It is recommended to achieve two consistent sets

: Jacking continues until "practical refusal" is reached. A common "set" criterion is a downward movement of not more than 10 mm held for at least 30 seconds Re-jacking Process
