Perth Airport (Forrestfield – Airport Rail ink)
Status:Construction underway
Value: $1.86 billion
Timeframe:Due to complete second half of 2021
Client:WA Public Transport Authority
Primary Contractor:Salini ImpregiloNRW Joint Venture
Steel supplier:InfraBuild Construction Solutions

Project Scope: 

The Forrestfield – Airport Rail Link will deliver a new rail service to the eastern suburbs of Perth, incorporating twin-bored tunnels and three new stations at Redcliffe, Airport Central and Forrestfield. The new link will connect Perth's growing eastern suburbs with the suburban rail network and it will play an important role in reducing congestion on some of Perth's busiest roads.

Western Australia's Public Transport Authority awarded the design, construct and maintenance contract to Salini Impregilo – NRW Joint Venture in April 2016.

The Salini Impregilo – NRW JV awarded InfraBuild Construction Solutions the contract to supply steel reinforcement over two major components of the project:

  1. 7200 tonnes of prefabricated diaphragm wall cages (completed May 2018)
  2. 7600 tonnes of conventional processed reo (supply ongoing)

 The materials have assisted in the construction of:

  • two tunnel dive and station box structures at Forrestfield and Bayswater
  • two station box structures at Airport Central and Redcliffe
  • three emergency egress shafts at Abernathy Road, Airport West and Weight Crescent

Over 160,000 units of Dextra Griptec mechanical splices have also been supplied by InfraBuild Construction Solutions.


"The next few years will mark the renaissance of rail in WA, with multiple projects getting under construction, creating a pipeline of work and local jobs."
Rita Saffioti, WA Transport Minister
