4 kilometres of track laid on Forrestfield-Airport Link

Work is rapidly progressing on the preparation of the Forrestfield-Airport Link to run trains by late 2021.

Tracklaying works have already put in place four kilometres of track through the twin tunnels.

The future stations for the line are also coming into shape, with the high eaves over Airport Central Station recently installed.

Connecting the station atrium to the platform is the longest uninterrupted escalator in the southern hemisphere, with stretches to 35 metres long and 15 metres high.

To date, 5.7km of skeleton track has been put down, and 3.9km of track completed for the 8.5km line.

Australian contractor Martinus Rail will use over 2,400 tonnes of Australian-made steel in the project, where it has employed more than 100 local workers.

WA Premier Mark McGowan said the project, which connects the existing rail network at Bayswater with the eastern foothills via Perth’s airport, has already provided many opportunities for local businesses.

“The Forrestfield Airport Link construction employs hundreds of local workers and provides opportunities for local businesses and subcontractors,” he said.

WA Transport Minister Rita Saffioti said that with major breakthroughs so far, it will not be long until commuters are using the new line.

“We’ve reached several milestones this year with the completion of tunnelling and the start of track laying,” she said.

“The stations are almost completed and it is exciting to think trains will be running on this line in late 2021.”

Martinus CEO and managing director Treaven Martinus said that with this project under their belt, Martinus will be looking to scale up for further projects.

“Currently, we have very skilled and experienced track and overhead wiring teams in WA but our vision has always been to expand the team to encompass civil and signalling capabilities,” said Martinus.

“There are many projects coming online and we are excited about what that means for us, the opportunities it provides for our teams, local businesses, and subcontractors.”

Claremont

Contract awarded for tracklaying at Claremont Station

The Western Australian government has announced the successful tenderer for the $36 million contract for tracklaying at Claremont station.

John Holland is the successful contractor and will complete the works at the station, part of the Metronet project.

Scheduled for completion in late 2021, with rail infrastructure operational by mid 2021, the work involves installing turnbacks west of Claremont Station on the Fremantle line.

The turnbacks will allow trains to travel back towards the city after stopping at Claremont. This will allow greater frequency services on the Fremantle and Forrestfield-Airport Link lines. Transport Minister Rita Saffioti said that local and city-wide works required the new infrastructure.

“We know significant development is taking place around Claremont Station – which is currently the third-busiest on the Fremantle Line – and we expect patronage of this station to increase significantly, which is why this upgrade is so important,” she said.

“Claremont Station is located halfway along the Fremantle Line, so is ideally positioned to host turnbacks – it’s a vital part of ensuring our rail network is well-placed to deal with future demand particularly when the Forrestfield- Airport Link comes online in late 2021.”

During normal peak periods turnback one will be used every ten minutes. Turnback two will be used during peak periods and special events as required, or when there are planned or unplanned service disruptions.

In addition to the new track, Claremont station will be upgraded to meet accessibility standards and a new underpass will be constructed. Bus facilities and pedestrian connections are also part of the project.

Saffioti said that works would support the local economy.

“This $36 million contract will help support 300 local jobs in the community, an excellent outcome for the project.”

Tracklaying

Tracklaying in progress on Perth’s future Airport Line

With tunnelling complete on the Metronet Forrestfield-Airport Link project, tracklaying has now begun along the 8-kilometre-long tunnels.

Martinus Rail will install the 40 kilometres of rail needed to form the track in each tunnel, along with tie-ins at Bayswater and stowage at High Wycombe.

The first kilometre of track has already been laid, and Western Australia Premier Mark McGowan said that this was a significant milestone on the project.

“Tracklaying is one of the final major events on the construction of a rail line – it’s an exciting milestone for this $1.86 billion project, with more than 2,400 tonnes of Australian-made steel being prepared.”

WA Transport Minister Rita Saffioti said that the project was coming together.

“We’re at an exciting time for this major infrastructure project – the tunnel-boring machines have finished creating our tunnels, our three new stations are taking shape and tracklaying is now underway.”

The 27.5m long pieces of steel are flash-butt welded into 220 metre strings. The Martinus teams have been working simultaneously to weld the rail, transport it and lay it along with the sleepers to form the skeleton track, before concrete is poured to complete the slab track.

Other work is also underway to install the overhead line equipment and the communications and signalling systems.

Roughly 100 jobs are supported by the tracklaying and rail infrastructure stages of the project.

Once complete, the Airport Line will link the Perth CBD with the airport and the eastern suburbs, including Redcliffe and High Wycombe. Thousands of commuters expected to use the rail link each day when trains begin running in late 2021.

WA resumes free late night trains

This weekend will see late night trains running again in Perth.

The decision to reinstate the 1am and 2am services from Perth and 2.50am service from Fremantle follows the re-opening of nightlife businesses in the state. Phase 4 of the WA lifting of coronavirus (COVID-19) restrictions come into effect at 11.59pm on Friday, June 26, allowing nightclubs, bars, and live music venues to re-open.

The services that will run again include 1.15am and 2.15am trains on the Joondalup/Mandurah lines from Perth Underground, 1am and 2.15am services on the Armadale/Midland lines from Perth Station, and services between Fremantle and Perth.

WA Transport Minister Rita Saffioti said that by having these trains back in service it will support hospitality and entertainment businesses.

“As our nightclubs and live music venues begin to re-open, it’s important we head back into the CBD and support our small businesses – reintroducing our free late night train services will give patrons a safe and hassle-free way to get home.”

Staff to run these trains have been quickly mobilised.

“I also want to thank our public transport employees, who have again stepped up to support the community during the pandemic. I appreciate the transport workers accepting short notice changes to their night shifts to make it possible,” said Saffioti.

Community chooses new station name

3,500 locals have chosen High Wycombe as the name for the final station on Perth’s new Forrestfield-Airport Link line.

Once complete, the line will be known as the Airport Line and will terminate in Perth’s eastern suburbs.

Saffioti said that early work on the station had begun.

“The start of construction for the car park is another step towards completion of the station precinct and will provide a further boost for local jobs.”

The Forrestfield-Airport Link is part of the Metronet project in Perth. Trains are expected to run on the line, which travels underneath Perth airport by 20201.

Digital engineering becoming more important than ever

While digital engineering has long been touted as the next technology that can create, manage, and utilise data for infrastructure development, the coronavirus (COVID-19) pandemic has brought it even more into focus.

With workforces forcibly distributed as remote working directives took effect, the value of having a rich virtual building information model (BIM) to enable seamless collaboration across physically distanced workforces has never been clearer.

Consulting company GHD has already exploited the value of digital ways of working in many projects, and recently in its work on the Forrestfield-Airport Link project – part of the Metronet project in Perth – within the Salini Impregilo and NRW Joint Venture.

According to GHD’s Rail Design Lead on the project, Martin Harle, using digital tools such as BIM, geographic information systems (GIS), analytics, coding, and automation, the team was able to eliminate clashes between different models by coordinating design through one model.

“Using this technology we are able to automate clash checks across multiple complex disciplines, highlighting design coordination issues in real time,” he said. “It helps to pre-empt and resolve potential construction problems during the design process, rather than dealing with unexpected issues as they occur on site.”

Avoiding duplication and replication, the BIM system enables costs to be reduced at the design phase. This not only improves processes at the construction site, but also enables suppliers to have a clearer idea of the concepts their assets will be working in.

“So far, on the Forrestfield-Airport Link, rail track and overhead line equipment has been designed and modelled 8.5 times faster and 1152 hours have been saved in automating 180 Navisworks exports,” said Martin.

Incorporating digital tools early on in the construction of a project can also lead to efficiencies once the project is operational. At the end of the design and construct phase, asset information can be handed over to the operator to promote ongoing efficiency.

The insights that GHD has gathered from this project have been used to advantage on other projects, including the Sydney Metro. And the lessons have wider implications through the Digital Engineering Code of Practice which will be applied nationally through the Rail Industry Safety and Standards Board (RISSB), which GHD helped design. GHD BIM lead – Western Australia and co-author of the code Belinda Thompson, said the benefits of the code are broad.

“By adopting Digital Engineering processes, increasing the accuracy of information and automating the data exchange processes, we can improve safety, reduce risk, achieve greater cost certainty and improved sustainability.”

TBM Sandy breaks through at Bayswater

Tunnelling is complete on the Forrestfield-Airport Link, part of the Metronet project in Western Australia.

On April 20, tunnel boring machine Sandy broke through at the Bayswater dive structure. WA Premier Mark McGowan said that the completion of tunnelling is a “major milestone” for WA.

“While Western Australia has been grappling with COVID-19, TBM Sandy and the project team have been continuing to work on this incredible project for Perth.”

The breakthrough ended 900 days of tunnelling under Perth Airport and the Swan River, creating 16 kilometres of tunnels, two twin 8km tunnels.

Now that tunnelling is finished, track will start to be laid from July 2020. The track slab is half installed while construction and fit out of the station buildings continues.

“In times like these it’s important we continue to progress projects that will provide work for local businesses and keep workers in their jobs, ultimately supporting the State’s wider economy,” said McGowan.

The tunnels, made with 9,000 tunnel rings comprising 54,000 locally made concrete segments, link three stations, Forrestfield, Airport Central, and Redcliffe to the wider rail network.

WA Transport Minister Rita Saffioti thanked those who have worked on the project so far.

“In July 2017, Premier Mark McGowan and I were at the Forrestfield Station site to mark the start of tunnelling on the Forrestfield-Airport Link,” she said.

“Thank you to the tunnelling team and other workers who delivered TBM Sandy to her destination and helped achieved this major milestone.”

The $1.86bn Forrestfield-Airport Link provides over 700 jobs in Western Australia, and is one of six Metronet projects underway in 2020.

The tunnelling for the Forrestfield-Airport Link was conducted by a joint venture of Salini Impregilo and NRW Civil and Mining which won the design and construct contract, along with a 10 year maintenance contract, in April 2016.

Contractor announced for Bayswater Station construction

The preferred proponent for the construction of the Bayswater Station is Evolve Bayswater Alliance, Coleman Rail.

The $253 million contract, awarded by the Western Australia government as part of the Metronet project, covers the building of the station, precinct works, new platforms, and rail infrastructure. The Bayswater station serves as a crucial linking point between the Midland Line to the future Forrestfield-Airport Link and the Morley-Ellenbrook Line.

Once construction is complete on these new lines, more trains will run more often between Bayswater and Claremont, driving greater use of public transport in Perth, said WA Transport Minister Rita Saffioti.

“Bayswater is on track to becoming one of Perth’s best connected communities, with access to three rail lines and many bus services,” she said.

A rail turnback for Forrestfield-Airport Link operations will also be built.

“In times like these it’s important we continue to progress the projects that will provide work for local businesses and keep workers in their jobs. This will ultimately support the State’s wider economy,” said Saffioti.

The contract will involve staged construction of the two island platforms. The first will be constructed while the current line and station are still being used. When complete, trains will begin using this new platform while the old station is removed and a new platform is built for the Morley-Ellenbrook Line.

“Building this project, combined with construction of other nearby major projects like the Tonkin Gap and Morley-Ellenbrook Line, will help support the WA economy through some tough times ahead,” said Saffioti.

Utility and environmental works have already begun at Bayswater Station, as have improvements to Meltham and Ashfield stations, and the future station will improve the surrounding community, said Maylands MLA, Lisa Baker.

“Bayswater Station is more than just a public transport project – the wider Bayswater community will also benefit with new public spaces and more pedestrian-friendly streets around the station,” she said.
