The Pengerang power line project was a MYR 200 million transmission infrastructure initiative designed to support power distribution across a 50-kilometer corridor in Johor, Malaysia. A key component of the project involved constructing a river-crossing transmission structure spanning two waterways, which introduced significant environmental and engineering constraints.
The project required the implementation of a hybrid structural solution combining lattice towers and steel monopoles. This approach had not previously been implemented in Malaysia, increasing the complexity of the design and requiring precise structural analysis and validation.
In addition, the design of the 275-kilovolt transmission monopole—reaching a height of 79.11 meters and recorded as the tallest of its kind in Malaysia—required careful consideration of structural integrity, environmental impact, and constructability. The team also needed to accommodate client-driven design changes while maintaining project timelines and cost efficiency.
Rohas-Euco Industries Berhad utilized Bentley’s structural modeling and analysis applications, including MStower and STAAD.Pro, to develop and validate the design of the steel monopole.
These tools enabled the team to perform detailed structural analysis and efficiently evaluate design modifications requested by the client. The integrated modeling environment provided the flexibility to simulate different design scenarios and ensure that the monopole met all engineering and safety requirements.
By leveraging Bentley’s applications, the team was able to streamline the design process, improve accuracy, and enhance responsiveness to design changes, ensuring that the final solution was both structurally sound and optimized for construction.
The implementation of advanced modeling and analysis tools significantly improved project efficiency and delivery performance.
Bentley’s integrated solution reduced design time by 50 percent, enabling faster turnaround of design iterations and improving overall workflow efficiency. This reduction in design time contributed to a 10 percent decrease in subcontractor costs, resulting in total savings of MYR 1.2 million.
The project was successfully completed on schedule without any issues, demonstrating the effectiveness of digital engineering solutions in delivering complex infrastructure projects. Additionally, the successful implementation of the hybrid monopole design established a new benchmark for transmission infrastructure in Malaysia.
