Geoss Guidelines On Local Practices For Pile Foundation Design And Construction -
The Geotechnical Society of Singapore (GeoSS) provides established guidelines for pile foundation design and construction, aligning local practices with Eurocode 7 (SS EN 1997-1). These standards cover performance-based design for bored piles, load testing with kentledge blocks, and specific procedures for jacked piles to ensure structural stability.

Holi:
The festival of colours, celebrating spring and camaraderie. Match pile type to locally available rigs, hammers,
- Match pile type to locally available rigs, hammers, and concrete supply; prioritize equipment proven with local soil types.
- For driven piles, choose hammer type (diesel, hydraulic) and formulate driving criteria (blow counts, set per blow, allowable refusal). Use pile driving analyzer (PDA) or dynamic monitoring if available; otherwise adopt conservative driving criteria and perform static load tests on representative piles.
- For bored piles, decide on casing, slurry, or secant pile approach based on groundwater and unstable strata. Employ rebar cages designed for handling and correct embedment.

- Review geological maps, aerial photographs, and historical land use (to identify obstructions or old foundations).
- Check for underground utilities and caves (especially in karst marble terrain).
Design Philosophies and Eurocode Integration
Modern practices under GEOSS increasingly align with Eurocode 7 . This involves using limit state design approaches and recommended factors of safety tailored to local soil parameters. For instance, in Singapore, allowable concrete compressive stress for bored piles is often limited to 7.5 MPa to ensure durability and safety. — End of paper —
