Geoss Good Practice For Installation Of Jacked Foundation Piles In Singapore -

End.

GeoSS recommends achieving two consistent sets before termination. It is particularly suited for sites adjacent to

Jacked piling (hydraulic jacking) is a preferred displacement piling method in Singapore for its low noise, zero vibration, and minimal spoil. It is particularly suited for sites adjacent to MRT tunnels, hospitals, and existing buildings. The Geotechnical Engineering Office, Singapore (GEOSS) promotes this practice to standardize installation quality and mitigate risks associated with the Kallang Formation, Old Alluvium, and Bukit Timah Granite. As Singapore builds deeper into its geology –

For further reference, consult BCA’s “GEOSS Technical Reference for Deep Foundations” (TR 60) and SS EN 1997-1:2010 (Eurocode 7) with Singapore National Annex. That is GEOSS.

As Singapore builds deeper into its geology – with projects like the Cross Island Line and Greater Southern Waterfront – the GEOSS guidelines for jacked piling will evolve. But the core principles remain: respect the clay, calibrate the jack, and log every millimeter. That is the good practice. That is GEOSS.
