• Byford Rail Extension Project


      ATCO is relocating sections of its high-pressure natural gas pipeline in and around Armadale and Byford to make way for METRONET’s Byford Rail Extension project. For more information on METRONET’s rail redevelopment project, visit metronet.wa.gov.au/projects/byford-extension


      ATCO’s main construction works will occur near to the rail line in both Armadale and Byford city centres. ATCO may also undertake minor works at other sites between Armadale and Byford.


      Based on our current construction schedule, ATCO’s construction works will begin in Armadale in August 2023 and continue through to October 2023.

      Construction is planned to commence in Byford from October/November 2023 through to 2024.

      More detail on the construction area and timeframes for each city centre is shown below.


    Summary: ATCO's major works are complete and most areas have been reinstated. ATCO will return for a period in December to commission the new pipeline to our active network.

    Aragon Court and Forrest Road: Asphalt road surfaces have been reinstated. Kerbing on Aragon Court is planned to be reinstated soon.

    Commissioning Works: ATCO will return in December to commission our pipeline and connect it to our active network. These works will occur near the rail corridor. Minimal impacts are expected to local roads or residents.

    Planned METRONET Works: Now that ATCO’s works are complete, METRONET can proceed with further plans for the Byford Rail Extension project. This could involve works by other utilities and traffic management in the area. For more information, visit METRONET’s Byford Rail Extension works page or reach out to the METRONET team here.

    Summary: ATCO's first stage of work on George Street is almost complete. George Street is planned to return to two-way traffic by Monday, 4 December.

    George Street: Two-way traffic is planned to be restored by Monday, 4 December 2023. Work sites that were excavated will be temporarily reinstated until they are able to be permanently reinstated (asphalted) in the new year.

    Corner Evans Way and Alexander Road: There may continue to be some minor disruptions to access at the corner of Evans Way and Alexander Road. There will be a short period in early December when ATCO will close a single lane on the corner as we conduct drilling beneath the rail corridor.

    December Works: ATCO's next stage of work requires us to drill under the rail line in two places at either end of George Street (near to Abernethy Road and also Evans Way) and there will be some traffic impacts from this work – the map below shows the affected areas.

    This work will occur around mid-December and be in place for a few days. During this work, George Street will be closed at Abernethy Road, and on Evans Way one lane will be closed.

    Byford Rail Extension Project


    • How is ATCO involved in the project?

      ATCO is relocating gas infrastructure in several locations in and around Armadale and Byford to support METRONET’s upcoming Byford Rail Extension (BRE) project. For more information on METRONET’s rail redevelopment project, visit metronet.wa.gov.au/projects/byford-extension

    • What areas are affected by ATCO works?

      Main construction works will occur in Armadale city centre, along Aragon Court and Forrest Road, and in Byford city centre along George St. ATCO may undertake minor works at other sites between Armadale and Byford from July 2023 onwards.

    • When are ATCO works expected to start?

      Based on our current construction schedule, ATCO’s construction works will begin in Armadale in August 2023 and may continue through to October 2023. Construction is planned to commence in Byford from October 2023 through to early 2024.

    • What will be the impact on me?

      If you live, work or attend venues near the construction areas, you may encounter traffic delays and some noise. More detail will be provided to those impacted as work becomes imminent.

    • Will there be impacts to traffic or business access?

      Yes – however this will be minor.

      Traffic management will be in place on all construction sites to ensure the safety of our crews and local traffic. Traffic delays and some noise are expected while works are underway. ATCO will endeavour to keep the community updated on any significant road closures or traffic management impacts. You may also contact us at any time to enquire about our current or planned works using the details located at the bottom of this page.

      Please follow all directions from ground crews and traffic management when navigating near or around a work site.

    • Will there be road closures?

      There may be some temporary lane closures, detours or road closures while work is taking place to ensure the safety of workers, residents and road users. In these cases, notice will be given beforehand and traffic management will be put in place. Please follow any detours that are in place.

    • Will the work be noisy?

      Construction noise during works is expected, but we will do everything we can to reduce the noise of the works during business hours: most likely between 7am and 7pm Monday to Friday.

      Noise management plans will comply with council guidelines.

    • How will the work be done?

      Our process involves using a combination of open trenches and trenchless technology to install gas mains.

      The trenchless method greatly reduces the time needed to complete works as well as reducing the impact to road users and businesses in the area. Traffic controllers will be onsite to ensure local traffic can move safely around the area.

    • Will there be interruptions to gas supply?

      No, there are no planned interruptions to gas supply as a result of these works.

    • Will there be an impact to my verge or property?

      Should you be an affected resident, you will be contacted directly about the impacts to your property.

      Building a pipeline involves digging open the ground to access pipes, valves and pits. This may impact roads, verges, driveways and footpaths.

      We are committed to returning areas affected by our work to as close to their original condition as reasonably feasible. We will work closely with local councils and affected property owners to try to meet restoration expectations wherever possible.
