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

Geotechnical Good Practice for the Installation of Jacked Foundation Piles in Singapore

Singapore’s urban landscape is characterised by high-density development, stringent vibration controls, and complex geological conditions, including the widespread presence of soft marine clay (Kallang Formation) and variable residual soils (Bukit Timah Granite and Old Alluvium). In this environment, jacked (or driven) piles—typically precast concrete or steel sections—are a preferred deep foundation solution. However, their successful installation demands adherence to rigorous geotechnical good practices, as codified under the Building and Construction Authority’s (BCA) Geotechnical Engineering Office’s technical references (commonly referred to as GEOSS – Geotechnical Engineering Observation and Site Supervision standards). This essay outlines the key good practices for the installation of jacked foundation piles in Singapore, covering pre-installation planning, installation control, monitoring, and quality assurance.
