Improving Travel Time between Cities by 50%

The West Coast KTM Bhd. line provides rail services in Kuala Lumpur and the surrounding Klang Valley suburban area. Over time, the single-track line has been steadily replaced with a double-track, overhead electrification system. The 197-kilometer section of the West Coast line that travels between Gemas to Johor-Bahru is the last section to be upgraded. Valued at MYR 9.4 billion, the project will decrease travel time between Gemas and Johor-Bahru from 7 hours to 3.5 hours. Pestech Technology Sdn. Bhd. awarded IOB Technology Sdn. Bhd. the consultancy contract for the eight traction-powered substations, which includes creating a 3D model. A manual approach to placing the overhead cantilever would require using CAD software to track the data for each mast placed, as well as the required revisions. Since that method would be too time consuming to meet the six-month schedule, they searched for an alternative solution.

Creating a 150-component Library for Different OCS Assemblies

IOB Technology needed to create a model containing information that would prevent clashes and coordinate the work of the other integrated disciplines working on the project. Their primary objective is to create a library of 150 components for the different OCS assemblies along the 197 kilometers of track and nine stations. They also needed to implement a BIM methodology for designing the traction-powered substations and the overhead catenary system to ensure they meet the main contractor’s objectives. To accomplish these priorities, IOB Technology looked for a solution that would enable them to perform the design and building information modeling tasks, as well as follow procedures and guidelines required by the main contractor. The software also had to be interoperable with the third-party software used by other contractors.

Improving Collaboration with Innovative Technology

IOB Technology turned to Bentley rail solutions to interface with the main contractor’s rail track and station information and used OpenUtilities Substation to integrate the power substation 3D models. To model the 150 components and OCS assemblies they used MicroStation and OpenBuildings Designer to reach a level-of-design 300 BIM standard. Once they modeled and assembled the components, they mounted the OCS systems to the scaffolding of nine stations along the track using different supporting masts. Additionally, they used OpenBuildings GenerativeComponents to place thousands of OCS assemblies along the track. Then they used the interoperability of Bentley solutions to convert the files to the required formats before submitting them to the contractor. To achieve their deliverables, IOB Technology team members worked simultaneously on a cloud-based server to ensure they had access to the latest information from all disciplines.

3D Visualization Reduces Resource Hours from 48 Weeks to 32 Weeks

Using the 3D visualization and space simulation capabilities in Bentley software enabled IOB Technology to explore spatial requirements and reduce design resource hours from 48 weeks to approximately 32 weeks. Additionally, automatically placing the overhead catenary structure along the 192-kilometer route using OpenRail saved eight weeks off the original 16-week schedule. Moreover, clash detection features in the coordinated 3D model reduced errors, potential rework, material waste, and risk leading to a 5% savings in construction costs. The overall benefits of implementing the innovative software applications saved more than MYR 100,000 in material waste and travel costs, and improved coordination among team members. The project is expected to be complete by November 2021.

Quote:
  • There were hundreds of OCS components, OCS assemblies, and substation equipment modeled in various Bentley applications, which were later placed onto the 197-kilometer railway track. The developed models were integrated with other contractors’ BIM software.
