Meinhardt has provided various engineering services for multiple MRT projects across three major lines - Downtown, Circle, Thomson & Tuas West Extension. This includes Lead Consultancy, Qualified Person (QP), Accredited Checker, Earth Retaining or Stabilising Structures (ERSS) Design, Traffic Diversion services and etc.
THE BIGGEST CHALLENGE
our engineers faced was to build the the underground station below and in between existing piles of the viaducts supporting the train tracks. This required careful design of the retaining structures and lots of measuring and testing along the way to ensure the the integrity of the existing underground structures were not compromised.

Analytical models were set up to analyse and predict structural settlement and forces induced under various stages of construction. Using 2-D Plaxis FEM analysis and 3-D StaadPro FEM analysis, we were able to accurately predict the amount of ground movement expected during the entire construction process and adjust accordingly for safe execution.
We used a real-time monitoring system that utilised an electro-level beam sensor to check any movement of the viaduct support structures in all directions. We also used settlement markers, tilt meters, rail gauges to monitor every single movement of the construction site and viaduct arising from excavation and construction works.
