The $1.86 billion Forrestfield-Airport Link is jointly funded by the Australian and Western Australian governments and will deliver a new rail service to the eastern suburbs of Perth – with three new stations at Redcliffe, Airport Central and Forrestfield.
The rail link forms part of the METRONET vision to create liveable communities connected by world class public transport. The line will spur off the existing Midland Line near Bayswater Station and run to Forrestfield through twin-bored tunnels. The project’s new rail services will fully integrate with the Transperth bus and train network, allowing a 20-minute rail journey into the Perth CBD from Forrestfield Station, as well as improved bus connectivity for the eastern suburbs, foothills and surrounding community. Redcliffe and Forrestfield stations will have rail-bus interchanges and up to 3000 new car parking bays.
In April 2016 the Public Transport Authority awarded the design, construct and maintenance contract to Salini Impregilo – NRW Joint Venture.
Forrestfield-Airport Link is fully funded and construction is already underway. Once operational the rail link will:
- Increase public transport options for the eastern suburbs and foothills area.
- Create additional capacity on the Midland Line to meet the growing passenger need.
- Support domestic and international tourism with improved access between the city and Perth Airport.
- Drive residential and commercial development around the new stations at Redcliffe, Airport Central and Forrestfield.
- Relieve pressure on Perth’s roads.
By 2021 the line is expected to generate 20,000 passenger trips on the network every day – increasing to 29,000 daily by 2031.
Sustainability has been identified as one of the State Government’s key attributes of the Forrestfield-Airport Link project. By extending the public transport network, the Project will make a positive contribution towards sustainable development in reducing vehicle use by commuters as well as improving the liveability, connectivity and amenity for current and future residents in the eastern suburbs.
Sustainable outcomes of note to date include:
- The majority of the alignment will be underground in twin bored tunnels leading to better environmental outcomesincluding less drawdown on the water table, fewer vegetation disturbances and reduced noise and vibration during construction and operation of the rail line.
- Station solar panels will result in a reduction of approximately 400,000 kWh per year, which is the same amount of electricity used by 56 Perth households per year.
- Concrete mixes are specifically tailored for the project’s needs, which has maximised the amount of recycled materials to be used. In some instances, up to 65% of Portland cement has been replaced with waste from other industries.
- Design features many new technologies and innovative aspects to ensure the safety of both passengers and staff throughout operation. This includes the use of a Fixed Earthing Device. The device allows the network to be isolated remotely and quickly, thereby removing the need for staff to undertake this onsite in a potentially hazardous situation.
- Ground freezing will be undertaken to install cross passages, reducing jet grouting requirements, thereby minimising materials. Ground freezing also allows for less intrusion above ground, both through not needing to work on the surface, and more control on the potential changes to the ground levels at the surface. Additionally, this technique only results in a temporary freeze to groundwater, rather than a permanent amount of concrete injected into the groundwater table.
- Offsets established for the project include 8.6ha of TEC and 49 individuals of Conospermum undulatum, on land that will be handed over into protection, and funding to continue protecting an existing population of an additional 1500 C. undulatum. This is considered an enhancement of ecological value as the project will impact 1.6ha of TEC SCP 20a and 25 individuals of C. undulatum.
- Sustainable water sourcing for construction is occurring across the project to avoid the use of potable water. Consideration is given to the set-up costs, as well as the additional haulage (emissions and financial), and the groundwater quality available at each site location. This has resulted in the main operations site yard at Forrestfield only using potable water for domestic purposes. All other operational water is sourced from the ground, and where the quality is not adequate, the water is processed in an RO Plant on site to enable its use in the grouting plant and the tunnel boring machines.
