Termination is typically based on achieving a specified "set" (a minimum penetration per number of jacking strokes) or a predetermined jacking force, as defined by the design. The piling supervisor must certify that the final criteria are met and that the pile is sound.
Heave monitoring of driven or jacked piles during installation is mandatory. This ensures that soil displacement does not cause adjacent piles to rise, which could lead to loss of capacity.
The proximity of jacked piling to existing infrastructure requires comprehensive risk management protocols. Termination is typically based on achieving a specified
The QP must maintain the following essential site and test records and keep them on site at all times:
Comprises highly weathered, interbedded sedimentary rocks. Sudden transitions from soft soil to hard rock layers can cause premature pile refusal or structural damage to the pile toe. Pre-Installation Engineering Requirements This ensures that soil displacement does not cause
In the dense, built-up environment of Singapore—where high-rise residential blocks stand metres away from MRT tunnels and heritage shophouses—construction noise is not merely a nuisance; it is a regulated liability. Over the last two decades, the Building and Construction Authority (BCA) and the National Environment Agency (NEA) have progressively tightened limits on impact piling. This regulatory push, combined with the city-state’s aggressive push for sustainable construction, has accelerated the adoption of (hydraulic jacking) over traditional diesel or air hammers.
The installation process must comply with and specific local good practices. Sudden transitions from soft soil to hard rock
Conducted on a select percentage of piles to confirm the settlement behavior under maintained structural loads.
