Unlike bored piling which generates wet soil slurry, jacked piling displaces soil laterally, keeping the job site dry and reducing waste disposal costs.
Do not attempt to achieve refusal by suddenly increasing hydraulic pressure. That cracks piles.
GEOSS defines termination not by a single number but by a three-part rule:
Implementing GEOSS good practices for jacked foundation piles ensures that Singapore’s infrastructure remains robust, safe, and community-friendly. By focusing on rigorous site investigation, precise verticality control, strict termination criteria, and thorough testing, engineers can confidently navigate the challenges of urban geotechnical construction.
Here is a breakdown of the key "Good Practice" requirements for the installation of jacked piles in Singapore:
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).
Vertical alignment must be checked continuously using two orthogonal plumbing instruments (theodolites or spirit levels).
The QP bears ultimate accountability for:
Executing jacked piling under the GeoSS framework involves precise coordination of heavy machinery and real-time electronic monitoring. Step 1: Rig Setup and Alignment
