With the placement of all 12 locally-fabricated steel modules complete, the 51m-wide station roof frame now stands proud and tall. Installation of roof sheeting, which will enable internal fit-out works during the rainy season, is scheduled next.

The Forrestfield Station roof is the biggest 3D puzzle on the project, with 600 steel lengths supporting about 2000 square metres of roof sheeting. Many Allen keys were required to turn this flat pack into a stunning architectural feature.

View the highlights of TBM Sandy's final breakthrough at Bayswater Junction, marking the end of tunnelling for the project.

Located immediately south of the control tower adjacent to Terminal 1, Airport Central Station will soon change travel to and from Perth Airport.

Located 9kms from Perth CBD, at the junction of Brearley Avenue and Dunreath Drive, Redcliffe Station will service the growing local community, as well as the airport business park and direct factory outlet.

Jump on board of TBM Sandy and let Alvin show you around the 9000-tonne machine.

Bit by bit 120 tonnes of galvanised steel are being installed at Forrestfield Station, forming the frame for the station's roof. Watch the work of 25 days condensed into 30 seconds.

Works at Bayswater Junction are underway to prepare for the TBMs’ arrival in early 2020. Once broken through, Grace and Sandy will be disassembled and craned out of the dive structure in parts. As the ladies are rather heavy, crews have strengthened the ground with 700 tonnes of compacted limestone to ensure the crane load is adequately supported.

Located adjacent to Dundas Road, east of the Forrestfield freight marshalling yard and south of Maida Vale Road, Forrestfield Station will provide an accessible and efficient transport option to and from the city for Perth’s eastern suburbs and foothills.

This month's anchormen, Andy and Ben, take you on a tour of the Airport Central site to show off the three level station and the newly installed triple escalator system (which will take only 55 seconds to travel from top to bottom!). Next up, construction of the station's walls and roof!

Watch the 15m-high and 35m-long main passenger escalator being installed at Airport Central Station. Once operational, the triple escalator system has the capacity to transport 8200 people per hour. Connecting the Skybridge to the concourse level, it is the longest single-span uninterrupted escalator in the Southern Hemisphere.

Tunnel boring machine Grace has broken through at Redcliffe Station, having successfully tunnelled 4.6km since starting her underground journey from Forrestfield mid-2017.

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.

The Forrestfield-Airport Link crew takes you right into the heart of the Bayswater construction site with this update on the dive structure concrete pours.

At 16.5 hectares, our Forrestfield Station site is (literally) kind of a big deal. Let our very own anchorman, site engineer Simon, take you on a guided tour.

Approximately 9000 rings of concrete, made up of six tunnel segments each, are required to build the tunnels for the Forrestfield-Airport Link. The video provides an overview of the production process.

Concrete pours are underway at Bayswater Junction to construct the base slab of the 400m dive structure, where the tunnel boring machines will emerge at the end of their 8km underground journey. 18 separate pours are required to construct the base slab, totalling more than 4000 cubic metres of concrete.

It takes 144 stairs to reach the bottom of the 36m-deep Airport West Emergency Egress Shaft (EES). This EES is one of three to be built along the Forrestfield-Airport Link alignment and, once complete, will provide access between both tunnels and to ground level for maintenance and in the event of an emergency.

Tunnel boring machine Grace reaches the halfway mark of tunnelling in November 2018 - a major milestone for the Forrestfield-Airport Link.

A dry box has been constructed where the TBMs will resurface in Bayswater at the end of their tunnelling journey. The box adjoins the Bayswater tunnel portal and is designed to correctly pressurise the TBMs’ final breakthroughs.

The large retaining wall built adjacent to Railway Parade to support the temporary Midland Line has been turned into a 500m piece of art thanks to PTA's Right Track program. Perth urban artist Drew Straker, in conjunction with 75 up-and-coming junior artists, completed the work of art inspired by native animals and WA landscapes (September 2018).

Redcliffe Station's base slab is taking shape with nine concrete pours, totalling 5500 cubic metres, scheduled as part of the construction of the 1.5m-deep station base.

Tunnel Boring Machine Sandy breaks through into the Airport Central Station box (May 19, 2018).

The Forrestfield dive structure, where the tunnel boring machines will launch from, is 260m long and up to 22m wide. It took seven months to build, but you can see how it was done in less than 70 seconds.

A 400-tonne crane is onsite at Forrestfield to help assemble our first tunnel boring machine (TBM). It can be seen here lifting the two heaviest sections of the TBM, the 164 and 143 tonne shields, into position.

Key components of our 600 tonne tunnel boring machine have now been delivered to the Forrestfield site. The $20m machine is one of two TBMs which will each dig 8km of 7m diameter tunnels from Forrestfield to Bayswater, with tunnelling due to begin later this year.
