If you thought that the Australian cities of Sydney and Melbourne were congested, spare a thought for the commuters of Kuala Lumpur. Ranked by the Asian Development Bank as the second most congested city in Asia, after Manilia, the region of Greater Kuala Lumpur is home to 7.25 million people, and is in the process of opening a three-line rapid mass transit system.
The first line, the Sungai Buloh-Kajang Line, opened in 2017 and the project team at MRT Corp wanted to take what they found in the process of constructing this line and apply it to the next two lines.
First is the Sungai Buloh-Serdang-Putrajaya Line, which is forecast to begin operating in July 2021.
One angle of improvement was time and cost certainty. Similar to other projects around the world, construction management was a key area, as the team identified the use of building information management (BIM) workflows as a way to improve this aspect of the project.
MRT Corp chose to adopt digital twins using Bentley solutions. This software enabled the project team to create and visualise its digital assets. From there, information on the status of elements of the construction process can be found, and the team can perform analysis and leverage insights through the system.
The BIM system from Bentley adopted by MRT Corp was able to leverage the projects Asset Information Management (AIM) system. This integrated documents, asset tags, equipment, maintenance class and frewquency, manufacturer’s name, and contact details, with the asset visualisation program.
This system will not only be of use during the construction phase of the project, but by having a Master Asset Register (MAR), operations and maintenance teams can easily access information on assets and equipment throughout the operational life of the railway.
“Going digital with Bentley, including our use of a digital twins approach, is helping MRT Corp to implement the business processes and systems it needs to spearhead the digital future of construction in Malaysia,” said Aswadi Yusof, BIM champion with MRT Corp.
During the construction phase of the project as asset data is introduced to the digital twin, assets can be visualised and located within the 3D model. This enables the project team to understand how this asset and equipment fits with other elements of the project. Bentley estimates that this will reduce the whole life cost of the railway.
