The Geotechnical Society of Singapore (GeoSS) has established a Guideline on Jacked Piles to standardize the installation of jacked foundation piles, a method favored in Singapore for its vibration-free and low-noise characteristics.
Why Jacked Piles Form the Backbone of Singapore's Urban Construction
Jacked piles, also known as jack-in piles, are a type of installed by applying static hydraulic pressure rather than dynamic impact or vibration. Precast concrete piles or steel sections are advanced into the ground using powerful hydraulic jacks that push against a dead-weight reaction (kentledge) or previously installed piles. As building codes transition to the Eurocode framework,
As building codes transition to the Eurocode framework, engineers must follow specific installation controls, verification criteria, and quality management frameworks to minimize ground movement and secure predictable pile capacities. Technical Overview of Jack-In Piling

The GEOSS standard is notably stricter on ground movement and verticality, recognizing Singapore's density of underground infrastructure.
