Technical Information
The elevated alignment has 24 stations (3 others have already been built as part of MRT Kajang Line) while 8 stations are underground (1 station has already been built as part of MRT Kajang Line). The total stations for Putrajaya Line is 36 operational stations.
Elevated Guideway
The elevated alignment of the Putrajaya Line will be built on guideways supported by pillars.
The height of the guideways depends on various factors such as the terrain on which it is built and whether it has to span over roads.
Tunnels
The underground alignment of the Putrajaya Line will be built within tunnels. The tunnels will be built using tunnel boring machines and also the cut-and-cover method. The depth of the tunnels depends on factors such as whether it has to avoid any underground structures and geology.

Building Information Modelling
The MRT Putrajaya Line has mandated the use of Building Information Modelling (BIM) workflow throughout the design, construction and operational stages of the project to fully utilise the potential for significant cost savings. MRT Corp has become the first infrastructure developer in Asia to achieve accreditation for its adoption of BIM Level 2.
BIM Level 2 involves the use of 3D models and information that are shared to all project stakeholders through a common database called the Common Data Environment (CDE), as opposed to BIM Level 0 and BIM Level 1 which do not provide a collaborative platform.
The BIM Level 2 workflow optimizes control and accuracy of project data, and improve design collaboration, construction feasibility, and accuracy of as-built information from the concept phase, to design, to construction and finally operation phase of a project.
Awards
The MRT Putrajaya Line has been recognised as the industry leader for advance digital technology implementation in BIM and Geographic Information System (GIS) in this region and as a testament to the use of technology to enhance productivity, efficiency and quality for project delivery.
