Geoss Guidelines On Local Practices For Pile Foundation Design And Construction Link

For detailed technical guidelines, professionals are encouraged to refer to the official GeoSS publications and BCA Eurocode guidelines.

6.2 Equipment selection and local constraints The inherent unpredictability of karst geology means that

Singapore’s western region sits on challenging limestone ground, where hidden cavities (karstic formations) can complicate piling works. Karst terrain presents unique risks: bored piles may encounter voids that reduce end bearing capacity, cause unexpected loss of concrete during casting, or lead to sudden collapse. The inherent unpredictability of karst geology means that even extensive site investigations may not detect every cavity. For detailed technical guidelines

The guidelines clarify the roles and responsibilities of project parties involved in bored piling works: or lead to sudden collapse.

The primary objectives are to provide guidance to all parties involved in kentledge setup, ensuring that the method is .

Key design considerations include:

Cutting open trenches or constructing temporary earth-retaining walls to isolate the project zone from sensitive adjacent utilities.
