: Rigs should undergo a regular maintenance regime with daily, monthly, and yearly checklists to ensure they remain in safe working condition. Verification and Load Testing
The draft guideline for the installation of jacked piles includes several "good practices" to ensure quality and compliance with Eurocode 7 . Key Good Practices for Jacked Pile Installation : Rigs should undergo a regular maintenance regime
Jacked foundation piles offer several benefits, including: : For large pile groups, it recommends an
: Unlike driven piles, every jacked pile undergoes a form of load testing during the actual installation process. This includes drilling boreholes
: For large pile groups, it recommends an "inside-out" jacking sequence or a fixed direction (e.g., left to right) to manage soil displacement. 4. Safety & Compliance
Before commencing the installation of jacked foundation piles, it is essential to conduct thorough site investigations to determine the subsurface conditions, soil properties, and potential hazards. This includes drilling boreholes, conducting standard penetration tests (SPT), and collecting soil samples to determine the soil's geotechnical properties. The site investigation report should provide essential information on the soil's stratigraphy, groundwater levels, and potential liquefaction risks.
