GEOS Good Practice for Installation of Jacked Foundation Piles in Singapore
- Accurate pile positioning: Ensure that the piles are installed at the correct position, angle, and alignment to prevent eccentric loading and pile damage.
- Soil disturbance minimization: Minimize soil disturbance during installation to prevent soil loosening, settlement, and lateral displacement.
- Pile driving control: Monitor pile driving parameters, such as driving energy, penetration rate, and hammer performance, to ensure that the piles are installed to the required depth and capacity.
- Pile integrity testing: Perform pile integrity tests, such as sonic echo or pulse echo tests, to verify the pile's integrity and detect any defects or anomalies.
- Quality control: Implement a quality control system to ensure that all installation activities meet the required standards and specifications.
- Site investigation: A thorough site investigation is essential to determine the soil conditions and identify potential issues.
- Pile design: The pile design should take into account the soil conditions, pile material, and load requirements.
- Installation procedures: The installation process should follow a systematic approach, including pile seating, jacking, and grouting.
Ground Movement Monitoring: Because jacked piles are displacement piles, monitoring heave and ground movement is mandatory to prevent damage to adjacent structures. GEOS Good Practice for Installation of Jacked Foundation
Jacked piles are preferred in Singapore's urban environment due to specific performance characteristics: Accurate pile positioning : Ensure that the piles
The Geotechnical Society of Singapore (GeoSS) provides guidelines for jacked foundation pile installation, emphasizing stringent controls on verticality, equipment calibration, and sequence to manage ground movement. Installation requires a re-jack process to reach specific settlement "set" criteria, typically 10mm or less, to ensure structural integrity. For the full guide, visit GeoSS.
