MMC-Gamuda KVMRT (T) Sdn Bhd is a joint venture company between two of Malaysia’s largest engineering construction groups, MMC Corporation Berhad and GAMUDA Berhad.


    Klang Valley Mass Rapid Transit (KVMRT) Project is a rail-based public transport network, envisaged to radically improve and transform Kuala Lumpur’s public transportation coverage and to propel the Greater Kuala Lumpur into one of the top most liveable cities in the world.

    The MRT project which was approved by the Malaysian Government in December 2010 and launched by Prime Minister Datuk Seri Najib Tun Razak on 8 July 2011, will help ease traffic congestion and increase the public transport modal share from 18 % in 2009 to 40 % in 2020.




    With part of the 51km Klang Valley Mass Rapid Transit (KVMRT) Sungai Buloh-Kajang Line (SBK Line) designed to traverse through heavily built and populated residential districts, business centres, commercial centres and key employment areas in the urban and suburb corridors of Klang Valley, MMC Gamuda KVMRT (T) Sdn Bhd, faced with land constraints, had little alternative but to take 9.5km of the alignment underground. The underground stretch begins near the intersection between Jalan Semantan and Jalan Duta, before winding through Muzium Negara, Pasar Seni, Merdeka, Bukit Bintang, Tun Razak Exchange (TRX), Cochrane, and ends at Maluri.



    An MRT system best serves its function by providing connectivity to the busiest population pockets, but these pockets are also extensively developed with narrow corridors and dense structures. An above-ground route especially in the heart of KL city for the MRT is simply unfeasible.

    The most challenging task in the underground tunnelling works for the Klang Valley Mass Rapid Transit (KVMRT) Sungai Buloh-Kajang Line (SBK Line) is the tough geological formations found underneath Kuala Lumpur city. The underground alignment for the KVMRT SBK Line will navigate past two distinctly different geological settings, with the extreme karstic limestone accounting for almost 50% of the underground alignment.

    Extreme karst is a geological formation consisting of weakly soluble bedrock such as limestone eroded by mildly acidic water over millions of years, leaving behind an elaborate labyrinth of unstable caverns, cliffs and pinnacles in the depth of Kuala Lumpur city.



    Our breakthrough engineering and high-technology approach has continuously positioned us as the leading force in Malaysia’s infrastructure planning and development, enabling us to set numerous benchmarks in the construction industry.

    Taking innovative engineering to the next level, we collaborated with the world’s largest tunnel boring machine manufacturer, Herrenknecht AG, to develop the world’s first Variable Density Tunnel Boring Machine (VD TBM).

    The development concept of the VD TBM was a direct result of our in-depth experience and understanding of extreme karst, gained during the construction of the Stormwater Management and Road Tunnel (SMART).



Underground Stations

Upon completion, the underground stations that will line the MRT Sungai Buloh – Kajang alignment will be world-class metro facilities that will not only be functional, but also aesthetic in design. The stations will employ green technology to boost energy efficiency and a number of features that will provide access to the disabled.

Each station will also serve as information centres for the MRT, and will provide information on the various lines, interchanges and transfer points. Interchange stations will clearly mark out the route for transfer passengers to enable commuters to change trains seamlessly.

Each station will also be given a unique identity to best reflect the relevant historical theme or activity of the location. The stations will also feature artwork by local artists as part of the “Art Express Programme”, where a panel of qualified people will select and commission appropriate artwork for each station.


Traffic & Enviroment

MMC GAMUDA KVMRT (T) SDN BHD is aware that the construction of the MRT may result in some unintended consequences such as traffic disruption, and environmental impacts, for instance noise pollution.

An extensive traffic and environment management programme has been put in place to ensure that construction will create a minimal amount of disruption.

A number of safeguards will be put in place near the construction site to ensure the safety of site workers and the general public, as well as to minimise inconvenience during construction. At some of these locations, traffic may be diverted or the road closed to ensure general safety in the area.
