Metronet Ellenbrook Line Integrated Systems Test, Perth

The Metronet Ellenbrook Line represents a step forward for public transportation in Perth’s north-eastern suburbs. This project addresses the need for greater transport choice and is integral to the region’s growth over the next three decades, promising residents enhanced access to housing, jobs and community services.

Delivered by Laing O’Rourke and the Public Transport Authority, the project includes the design and construction of 21 kilometres of new rail, 5 new stations—Morley, Noranda, Ballajura (formerly Malaga), Whiteman Park and Ellenbrook—with future provision for a station at Bennett Springs East. Our engagement focused on the commissioning of critical systems across these stations, with an emphasis on integrating both technology and safety measures in line with project objectives.

Our team conducted comprehensive integrated system tests (IST) for all 5 stations, which included fire safety systems, electrical mains failure and various mechanical operations. By creating clear, user-friendly scripts for testing procedures, we ensured that all safety protocols could be easily understood and executed, meeting our client’s vision for public safety and functionality at commissioning stage, but also into the future as scripts are included in the stations’ operations and maintenance manuals.

Each station includes a sophisticated backup power system designed for reliability and safety. In the event of a local power failure, the stations seamlessly transition to a backup power source via automatic transfer switches that draw power from the rail lines through transformers. This ensures that essential services, such as emergency lighting and communication systems, remain operational. Additionally, provisions are in place for temporary generator connections to maintain operations until permanent solutions are restored, enhancing safety and service continuity.

Of the 5 stations, 2 are G-star Green Star-rated stations—Ballajura and Ellenbrook. For commissioning of these stations, we took an active role in the compliance process, ensuring they not only met conventional building standards but excelled in sustainability practices. This included rigorous documentation and collaboration with stakeholders to achieve Green Star certification.

Our commissioning activities addressed the critical aspects of safety and ease of access for users. Through systematic testing of public address systems and emergency protocols, we supported provision of reliable information for both staff and passengers during their transit experience.

The Metronet project was subject to tight deadlines, necessitating a rapid response in several instances. Despite the pressure, our team efficiently delivered multiple ISTs and adapted quickly to the need for expedited scripts, ensuring that all testing phases were completed on schedule to meet project deadlines.
Navigating the extensive documentation and harmonising input from several contractors posed a challenge. Our commitment to clarity and proactive communication enabled us to maintain momentum and foster collaboration among various project stakeholders, ensuring the flow of valuable information essential for decision-making.

Throughout the commissioning process, non-conformances were generally minor, a testament to the high-quality standards upheld by Laing O’Rourke and their professional subcontractors. Our structured logging and reporting mechanism enabled swift identification and resolution of any issues. Communications with contractors ensured prompt correction and most non-conformances were dealt with efficiently, allowing us to maintain project timelines without compromising on safety or functionality.

The Metronet Ellenbrook Line project highlights how thoughtful engineering and thorough commissioning can elevate community transport systems. By prioritising user experience—with a focus on safety, reliability and sustainability—it achieves our client’s goals while creating meaningful benefits for the communities it serves. This project supports better transport outcomes and contributes to a more connected future.
