This new standalone railway will deliver 31 metro stations and more than 66 kilometers of new metro rail, revolutionizing the way Australia’s biggest city travels.
Metro means a new generation of world-class fast, safe and reliable trains easily connecting customers to where they want to go. When services start in the second quarter of 2019, customers will not need timetables – they will just turn up and go with a train every four minutes in the peak.
Technology will keep customers connected at all stages of their journey, from planning at home using smartphone travel apps, real-time journey information at metro stations and on board trains, and accessing information and other public transport to help get to their final destination after they leave the train.
This approach will help customers achieve their daily tasks, whether it is getting to work, meetings, school or education, sport, a day out or running errands and of course, getting home.
When Sydney Metro is extended into the central business district (CBD) and beyond in 2024, metro rail will run from Sydney’s booming North West region under Sydney Harbour, through new underground stations in the CBD and beyond to the south west. There will be ultimate capacity for a metro train every two minutes in each direction under the city, a level of service never before seen in Sydney.
A flagship project for Boral in New South Wales
John Holland CPB Ghella (JHCPBG) has been contracted to design and construct the tunnel and station excavation works for Sydney Metro City and Southwest.
Twin 15.5 km tunnels from Chatswood to Sydenham traveling under Sydney Harbour using five TBMs
Construction of two dive sites at Chatswood and Marrickville and a rail crossover cavern at Barangaroo
Excavation of six new underground metro stations at Crow’s Nest, Victoria Cross, Barangaroo, Martin Place, Pitt Street and Waterloo
Precast facility at Marrickville to produce about 99,746 precast concrete segments to line the tunnels
JHCPBG is committed to supporting local businesses for the benefit of the project and subcontracted the supply of the concrete for the tunnel lining segments to Boral Australia.
During the early pre-tendering stages, JHCPBG invited Boral to trial specialized concrete mixes for the precast segments at Boral’s facility. Extensive quality, performance and fire testing was conducted, said Andrew Legge, Project Director – Major Projects, on the project. “We consider it an honor to be working with Transport for NSW and the NSW Government to deliver Australia’s biggest public transport project, which will transform the way people get around Sydney,” he said. “Boral’s technical knowledge and the ability to perform these trials and tests before a contract was awarded helped de-risk the process for the client at an early stage of the project.”
Philip Mallam, Asset Manager NSW/ACT Concrete, adds: “The turnkey project as concerns site organization, erection and lifting equipment has been really well organized by all the parties involved from Boral and MCT Italy. The customer supported us with genuine, collaborative spirit from day one: in such conditions every project is a guaranteed success and it means a long-lasting relationship”.
Allan Styner, Boral Capital Procurement Manager, affirms: “Winning the Sydney Metro project confirms Boral’s solid construction presence in Australia. The company is also part of the successful Forrestfield tunnel project in Perth which is going to be completed breaking records in production time”.
Masterpiece precast segment production
A Marrickville warehouse has been transformed by JHCPBG and Boral Construction Materials into a facility to batch the concrete and produce the tunnel lining segments. The segments are trucked for temporary storage to the construction site, from where they are delivered into the tunnel boring machines (TBMs).
MCT Italy, in a true partnership with the Australian Partner Bennett Equipment from Adelaide, delivered a special concrete batch plant to Boral specifically designed to produce the concrete for the tunnel segments.
The high-quality concrete containing 30 kg of steel and 1.5 kg of polypropylene fibers per cubic meter is batched by a No. 2 Eurostar 3000/2000 planetary mixer. The concrete has undergone a series of tests to ensure it meets the required standards for strength and durability.
Very strict tolerances lower than 1% on all dosed components ensured success in the most severe tests, including fire testing held in New South Wales, Australia.
Segment production in full swing
The first of 99,746 concrete segments came off the production line in April 2018, and will be used to line the 15.5 kilometers twin metro railway tunnels from Chatswood to Sydenham:
Six concrete segments will make up one tunnel ring, which is installed underground by a tunnel-boring machine as it moves forward.
Each tunnel will be lined with 16,451 concrete rings.
The specialized concrete factory in Marrickville produces one four-tonne segment every six minutes.
NSW Transport and Infrastructure Minister Andrew Constance said: “Sydney Metro is a game-changer for Sydney which will revolutionize the way we get around our great global city for future generations to come – metro rail is here to stay”.
He continues: “New world-class metro rail services will start before we know it – in the first half of next year in the booming North West, then extending into the CBD and beyond to Bankstown. In 2024, Sydney will have 31 Sydney Metro stations and 66 km of new metro rail, with a new metro train every four minutes in each direction in the peak.”
MCT Italy strengthens market competitiveness of Australian precast producers
Also Gabriele Falchetti, Executive Australia Sales Manager of MCT Italy, was delighted to be a part of a strong focused team to deliver a key section of the Sydney Metro project, with such a unique element of the work – rail tunnels under Sydney Harbour: “We recognize the importance of the project and will ensure our collective proven experience and expertise is focused on delivering this world-ranking project and its objectives, including sustainable design and construction.”
Australian Government is investing a lot, and Gabriele Falchetti adds: “Infrastructure projects are increasingly opening up opportunities. For this reason, MCT Italy’s plants in Perth and Sydney draw the attention of the National Precast Association of Australia, which is organizing a factory visit during their next meeting in November 2018. Construction of new tunnels for trains and metros is expected in the near future and we are ready to put our technology, expertise and after-sales support at the service of our new customers”.
