Main contractor MMC Gamuda has appointed Maxwell Geosystems to provide instrumentation and monitoring systems for the underground sections of the Klang Valley MRT in Kuala Lumpur.
The first section to be built will be a 9.3km tunnel, constructed by tunnel boring machine (TBM), between Semantan and Maluri and will include seven station boxes, three emergency escape shafts and two intervention shafts.
According to Maxwell, the alignment will pass through some challenging ground conditions including karstic limestone with caves and cavities, which is overlain by soft soil. The route takes the MRT below some densely populated areas and a number of heritage structures and Maxwell is working with the main contractor to develop a robust approach to geotechnical and structural risk monitoring during the work.
Maxwell has said that it will integrate construction and TBM data with instrumentation data to create a shared real time “cause and effect” analysis system to allow the project teams to predict and control the ground and groundwater movements.
