KVMRT Kajang Line Rail Asset Condition Survey, Kuala Lumpur

Keeping Kuala Lumpur commuters on the move

Operational resilience of any public transport system is critical to fulfilling its role in supporting economic activity, taking traffic off the roads, providing a reliable service for its customers and supporting communities.  

We were asked to perform Malaysia’s first major Rail Asset Condition Survey on the Kajang Line, part of the Klang Valley Mass Rapid Transit (KVMRT) system in Kuala Lumpur.  

The KVMRT is one of the most important and largest transport infrastructure projects Malaysia has ever embarked on. It is a part of the government’s vision to create a transportation backbone for the greater Kuala Lumpur and Klang Valley region. The seamless running of the Kajang Line, the first to be completed of the three MRT lines, is critical to its success.  

Appointed by the Mass Rapid Transit Corporation Sdn Bhd (MRT Corp), the developer and asset owner, we assessed the condition and deterioration of the assets on this 51km line. By using ‘Marq’ – an Arup-designed digital tool – we have been able to provide them with the insight necessary to better plan their maintenance regimes for the future.  

We also created a strategic asset management framework for MRT Corp. This provides them with a tool to more proactively plan an approach to any future rail linkages, including the upcoming Putrajaya Line. This joined-up, ‘holistic’ approach to asset management allows better planning, and with better planning comes better cost-effectiveness and the ability to deliver a safe, fast and reliable rail network for customers.

1st major Rail Asset Condition Survey in Malaysia

51kmline, 31 stations

Bolstering public infrastructure resilience with digital

Arup’s web-based mobile collection tool ‘Marq’ was used. This enabled us to easily capture asset photography and other observations. 

We collated findings from almost 20 sub-systems across the Kajang Line. Our survey team of 50 people worked on site daily for a month, with coordination carried out through multiple workshops and brainstorming sessions. We also tapped into Arup’s global expertise. 


We adopted a risk-based sampling approach for this survey, with factors including health and safety, environmental impacts and service levels considered. 

We reported our findings, conclusions and recommendations from the survey, including a complete database of the survey findings, forecasted remaining asset life, and identified any assets where remedial action was needed.  

This tool was integral to the success of this project, keeping commuters between Kuala Lumpur and outlying areas on the move.

The excellent findings of Arup’s survey and asset management framework recommendations support our goal of providing reliable and safe rail services to Klang Valley commuters. ” Ir. Major Rtd Mohamed Shuhaidi Omar Head, Assets & Facilities Management, MRT Corporation
