While conventional codes focus primarily on piled foundations, there is limited guidance on the soil investigation, design, construction control, and monitoring of raft or piled‑raft systems. This 2024 circular fills that void, providing a framework for adopting raft or piled‑raft foundations as cost‑effective solutions for high‑rise buildings and infrastructure, provided they are founded on competent ground.
: To protect adjacent structures, local practices recommend installing relief wells (typically 400–600 mm diameter) or temporary earth-retaining walls to contain movement within the site boundary. Here is the uncomfortable truth the GEOSS guidelines
Here is the uncomfortable truth the GEOSS guidelines highlight: The best pile driver on site is usually illiterate in engineering formulas, but he can read the soil. 2/96 (Pile Design and Construction)

While "GEOSS" is often used to refer to the digital submission system and standards in Hong Kong, the technical guidelines for pile foundations are derived from key publications such as and GEO Publication No. 2/96 (Pile Design and Construction) . Here is the uncomfortable truth the GEOSS guidelines
GEOSS integrates these local "hacks" with satellite interferometry (InSAR) and ground-based sensors. The result? A hybrid approach that respects the past while predicting the future.
: Typical allowable pile top settlements under load tests are: under 1.5 times the working load. under 2.0 times the working load. Unit Resistance
