Geoss Good Practice For Installation Of Jacked Foundation Piles In Singapore Hot!

Specialist builders must perform Sonic Logging or PDA/PIT tests to detect hidden underground defects.

As Singapore continues to develop its underground and vertical infrastructure, jacked piles will remain a cornerstone of silent piling technology. By following these guidelines, the industry ensures that our foundations are not only quiet but unshakably safe. Specialist builders must perform Sonic Logging or PDA/PIT

| Test | Requirement | |------|-------------| | | 1% of piles, up to 1.5× working load (max 2.0× for proof test) | | PDA / high-strain dynamic test | 5% of piles (correlated with jacking records) | | Sonic logging (for large diameter >400 mm) | If specified by design | | Heave monitoring | 2–3 benchmarks near pile group | | Test | Requirement | |------|-------------| | |

Mandate continuous digital tracking of the alignment and stop jacking immediately if abrupt spikes in force occur alongside sudden tilting. 📊 Quality Assurance and Testing Framework Specialist builders must perform Sonic Logging or PDA/PIT

) applied to the pile must be carefully balanced. It must be high enough to overcome soil resistance but low enough to avoid crushing the concrete pile head.
