Mass Rapid Transit Corporation (MRT Corp), developer of Malaysia’s largest transit project, successfully opened its Sungai Buloh-Kajang (SBK) Line in the Greater Klang Valley Region of Kuala Lumpur in 2017. Keen to leverage the wealth of experience that MRT Corp benefited on that project, the group focused its efforts on enhancing time and cost certainty via the adoption of multi-discipline BIM workflows on the Sungai Buloh-Serdang-Putrajaya (SSP) Line, its second of three lines. Moreover, having identified a number of challenges in construction management and handover of digital as-built data to operations, MRT Corp determined to advance its BIM workflows via the adoption of digital twins using Bentley solutions. By going digital, MRT Corp can create and visualize its digital assets, as well as take a look at their status, perform analyses, and leverage insight gained to predict and optimize the organization’s performance.
MRT Corp’s Asset Information Management (AIM) system keeps a list of documents, asset tags, and equipment, along with the maintenance class and frequency, manufacturer’s name, and contact details. To control its data, MRT Corp created a custom classification system – the KVMRT Classification System – using Asset Wise in its cloud-based connected data environment (CDE). By setting up a Master Asset Register (MAR), the system can be used to capture all the pertinent data associated to assets and equipment, which will be used via the operations and maintenance groups during the operational life of the railway. The best of data is radically increased via its validation against MRT Corp’s standards to identify inaccurate, incomplete, or duplicate information and prevent it from entering the system. The project crew uses the system to drill down via the asset hierarchy and find an asset in the register when the asset name or number is not known. The system makes it easier for teams to interact with asset information and get responses to the queries about a system or subsystem.
Asset data contributed to the digital twin during design, procurement, and commissioning remains available at each and every phase of the lifecycle, thereby easing discovery and access to information. Maintaining comprehensive data on the assets during project delivery minimizes the amount of human interaction needed throughout asset handover to operations.
Adopting this method using Bentley applications is enabling MRT Corp to acquire compliance with the United Kingdom government’s Level 2 BIM maturity, a standard mandated for this project. Using iModels, the team at MRT Corp can visualize and find an asset in the 3D model and attain a higher perception of linked or associated assets and equipment. Moreover, increased insight gained via this method is enabling the crew to enhance decisions that will eventually make contributions to a reduction in the whole life cost of the railway.
“Going digital with Bentley, which includes our use of a digital twins approach, is helping MRT Corp to implement the business processes and systems it wants to spearhead the digital future of construction in Malaysia,” stated Aswadi Yusof, BIM Champion with MRT Corp.
