The project comprises the design, construction and maintenance for 10 years of the Forrestfield-Airport Link, which will connect the eastern suburbs of Perth with the existing suburban rail network as well as the airport. By 2021 the line is expected to generate 20,000 passenger trips on the network every day It will also reduce road traffic and travelling times.
Salini Impregilo and its joint-venture partner NRW Pty Ltd (80% of the joint-venture is held by Salini Impregilo) will build three stations, twin-bored tunnels, three emergency egress shafts and parking spaces.
Each tunnel is 8 kilometres long (internal diameter 6.17 m and excavation diameter of 7 m), for which two TBMs (Tunnel Boring Machine) have been specifically designed.
The project is registered and will be seeking, as a minimum, an Excellent rating under the Infrastructure Sustainability (IS) rating scheme, which is administered by the Infrastructure Council of Australia (ISCA). The scheme provides a framework for the implementation and evaluation of sustainability initiatives and potential environmental, social and economic impacts of infrastructure projects and assets.
