Geoss Good Practice For Installation Of Jacked Foundation Piles In Singapore Jun 2026

Jacked-in steel pipe piles and jack‑in steel H-piles are explicitly listed as acceptable pile types by HDB, alongside bored piles and micropiles (timber piles are not acceptable).

Limit the maximum jacking force to 40% of the pile’s characteristic concrete cube strength ( 0.4fcu0.4 f sub c u end-sub

Adhering to a standardized operational sequence minimizes structural failure risks and ensures the foundation performs as designed. Jacked-in steel pipe piles and jack‑in steel H-piles

During installation, the pile must be monitored for verticality and structural integrity. In Singapore, it is standard practice to maintain a vertical tolerance of 1:100. Piles are typically installed in segments and joined by welding or mechanical joints. For welded joints, non-destructive testing (NDT) is essential to ensure the connection can withstand the intense compressive forces of the jack.
