Deep bored-pile foundation system on a constrained urban site beside a live MRT line.
The challenge
Piling within metres of a live MRT line, with strict vibration and settlement limits and no room for error.
Our approach
Low-vibration bored-pile methods with continuous instrumentation and real-time settlement monitoring tied to agreed trigger levels.
The outcome
Foundations completed within all movement limits — no impact to rail operations.
