Metronet Byford Rail Extension, Perth, WA

With changing population demographics and a growing residential presence in the southeastern suburbs of Perth, the state government recognised that the existing Armadale Line required an extension to serve the evolving needs of the community and provide increased access to the CBD for students, workers and commuters.

The Armadale Line will be extended approximately 8 km south to a new ground-level station in Byford, supporting one of the fastest growing areas in Australia.

Armadale Station will be rebuilt as an elevated station with 3 nearby busy level crossings removed and replaced with elevated rail. Other level crossings between Armadale and Byford will also be removed with alternative treatments to improve traffic flow and ease road congestion.

The project team is focused on providing exceptional quality rail systems design, compliance and operational readiness with minimal downtime and disruption to existing suburban rail services.

To achieve this, NDY is undertaking detailed planning, coordination, and scheduling between engineering disciplines and with our client. The systems engineering and assurance methodologies adopted further support design standards and safety compliance.

Our design maximises the use of prefabricated and standardised components for increased site safety and construction efficiency with minimal material waste and disruption. Pre-installation factory testing on materials and components will minimise potential defects over the life of the project, with a local factory providing local servicing and maintenance as needed in future years.

NDY is using advanced building information modelling (BIM) techniques on an integrated BIM 360 platform to deliver the design. This includes design comments resolution and verification, coordination, construction cost assessment and programming. This combination of software supports improved quality and accuracy of documentation. It also enables collaborative design review, speeds up clash detection and resolution of issues and provides excellent 3D visuals for a detailed understanding of the built environment.
