The following good practices should be followed during the installation of jacked foundation piles:
All pile foundations in Singapore must be designed with a to ensure structural resilience and public safety.
For any jacked pile in Singapore, the following records must be kept for inspection by BCA (Building & Construction Authority) and LTA:
4.2 Risk Register
This article outlines the key best practices for installing jacked piles based on GEOSS guidelines and local industry standards. 1. Pre-Installation Site Investigation and Preparation
Introduction
A comprehensive record of all installations, including daily reports, jacking logs, heave monitoring data, and test results, must be maintained. Supervisors must submit interim certificates at defined milestones (e.g., 50% and 100% of pile installation) to the Commissioner of Building Control. The following good practices should be followed during

The serves as the definitive engineering benchmark for urban deep foundation execution. Published by the Geotechnical Society of Singapore (GeoSS) in collaboration with local statutory boards like the Building and Construction Authority (BCA), this guideline standardises the design, installation, and quality assurance of jacked piles across the island.
In the dense, high-stakes urban environment of Singapore, foundation construction is a discipline defined by constraints: tight project schedules, proximity to existing Mass Rapid Transit (MRT) tunnels, strict noise pollution regulations, and the omnipresent soft marine clay of the Kallang Formation. For decades, driven piles (using hammers) were the default solution for transferring heavy structural loads to competent bearing strata. However, the environmental and technical demands of modern Singapore have accelerated a shift toward a quieter, more controlled method: . Published by the Geotechnical Society of Singapore (GeoSS)

In Singapore, jacked piles are particularly advantageous in with nearby structures and sensitive residents. The jacked piling system uses dead weights to exert hydraulic pressure to push piles into the ground, producing less noise and vibration compared to driven piles, making it suitable for projects in urban areas where residents are sensitive to noise and vibrations.
While jacked piling avoids the dynamic structural damage risks associated with impact hammers, it introduces specific geotechnical challenges that require strict risk management. Risk Factor Engineering Impact GeoSS Recommended Mitigation Strategy this guideline standardises the design
