Mass Rapid Transit Corporation

Project

The Klang Valley Mass Rapid Transit (KVMRT) Sungai Buloh-Serdang-Putrajaya (SSP) Line is the second mass rapid transit line being developed for the Greater Kuala Lumpur-Klang Valley region of Malaysia. The railway project spans 52.2 kilometers, 13.5 kilometers of which is underground, and includes 35 stations. Upon completion, the transit line will serve approximately 2 million people. MRT Corporation (MRT Corp) – the owner and developer of the SSP Line – mandated use of BIM to improve design collaboration, construction feasibility, and accuracy of as-built information.

Solution

MRT Corp leveraged a BIM Level 2 workflow to execute its BIM strategy designed to bridge the gap between asset information collected during construction, and that stored in its computerized maintenance management system (CMMS) database, which will be used to operate and maintain the railway upon completion. As a result, all asset data was effectively managed throughout the project lifecycle. Bentley’s connected data environment (CDE) uses ProjectWise and AssetWise, and leverages Microsoft’s Azure cloud services, to enable multi-discipline design collaboration from any location, plus the management of asset information to ensure optimal asset performance during operations and maintenance. To verify critical project milestones, the team used 3D photogrammetry, importing point clouds into the 3D construction models to reference existing conditions. 

Outcome

MRT Corp’s BIM standards and strategy, including digital workflows, improved design collaboration and coordination, construction feasibility, and accuracy of as-built information for the underground work for the SSP line. As one of the first transit system owners to implement cloud-based collaboration, MRT Corp aims to complete the SSP Line on-time and within budget. In addition to reducing the number of design interface issues from 4,000 to 1,000, Bentley technology has cut rework, improved multi-discipline design collaboration, and is delivering a 35 percent increase in productivity due to its ability to seamlessly share accurate information in real time.

OUTCOME / FACTS

• MRT Corp’s BIM strategy, including digital workflows enabled by Bentley technology has improved design collaboration productivity by 35 percent.
• Bentley’s CDE leverages Microsoft’s Azure cloud services to enable multi-discipline design, improve construction feasibility, and deliver accurate as-built information.
• Critical project milestones verified using 3D photogrammetry of existing conditions within 3D construction models.

QUOTE

“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.”
