Geoss Guidelines On Local Practices For Pile Foundation Design And Construction |best|

GEOSS (Geotechnical Society of Singapore)

The guidelines on local practices for pile foundation design and construction provide a standardized framework for the Singapore construction industry, particularly transitioning from British Standards to Eurocodes. These guidelines emphasize local soil conditions, structural safety, and rigorous testing. 1. Core Design Principles

Ground Movement Control

: 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. GEOSS (Geotechnical Society of Singapore) The guidelines on

Risk Assessment

: Evaluating flood plains and liquefaction zones using historical GEOSS data sets. Design Methodologies Buildings Ordinance: The statutory requirement

"Sunset Clause"

Some academics argue that relying on local practices preserves unsafe traditions (e.g., under-reinforced piles in seismic zones). GEOSS’s rebuttal: The guidelines include a —any local practice that has caused >5 failures in the GEOSS database is automatically flagged as "Obsolescent" and requires 2x safety factor.

7. Common Non-Conformances and Mitigation

• Buildings Ordinance: The statutory requirement.
• Code of Practice for Foundations (PNAP 66): The legal code outlining design requirements.
• Geoguides: Best practice manuals for investigation, design, and construction.
• Geospecs: Technical specifications for ground investigation and piling works.
