The GEOSS good practice bridges the gap between international standards (BS EN 14199, Eurocode 7) and Singapore’s legislative reality (Building Control Act, LTA’s Civil Design Criteria).
Designs must comply with Eurocode 7 (EC7) and the National Annex, which superseded SS CP4 in April 2015.

A pile is generally considered "set" if the downward movement does not exceed 5mm to 10mm while holding the force for at least 30 seconds .
As Singapore continues to develop its underground and vertical infrastructure, jacked piles will remain a cornerstone of silent piling technology. By following these guidelines, the industry ensures that our foundations are not only quiet but unshakably safe. As Singapore continues to develop its underground and
4.3 Permits and Coordination
Additionally, all jacked piling works must be supervised by a registered under BCA’s IES/ACES scheme, with a copy of the GEOSS checklist submitted to QPS (Qualified Person Supervision) daily. The hydraulic jacking machine must be sized appropriately
The hydraulic jacking machine must be sized appropriately for the design load. A key good practice is the regular calibration of hydraulic gauges. Since the pile capacity is often inferred from the jacking pressure, inaccurate gauges can lead to catastrophic foundation failure. Furthermore, the machine must be perfectly leveled. Even a slight tilt during setup can lead to eccentric loading, causing the pile to deviate from its vertical alignment or crack under pressure. Execution and Monitoring
