Gamuda played a leading role in the joint venture which constructed Malaysia’s first Mass Rapid Transit (MRT) system in Kuala Lumpur.
One of Gamuda’s most significant contributions to the MRT, as the design and build contractor for the underground section, was tunnelling one fifth of the Kajang Line, which stretches 51km from the north-west of Kuala Lumpur, through the city centre to the south-east.
The Variable Density TBM raised the bar for innovation in engineering. During use, the TBM pushed slurry into cavities detected in the limestone rock ahead of the machine’s cutter. By varying the slurry density, this stabilised the tunnel face, minimised the risk of sinkholes appearing on the land surface, prevented tunnel collapse and helped protect the TBM from damage. This provided evidence that tunnelling in challenging ground conditions can be carried out safely.
Gamuda leveraged its engineers’ technical innovations to safely and successfully complete this landmark project. The success of the project also led to Gamuda delivering MRT Putrajaya Line, solidifying the company’s reputation as the premier rail and infrastructure partner in Malaysia.
