New underground station
Barangaroo Station is a new underground metro station being built to serve for the inner-city Barangaroo precinct in Sydney, Australia. With an estimated investment of A$217m ($168.33m), the station development project is expected to be completed in 2023.
The new station is part of the under-construction Sydney Metro City & Southwest project which also includes five other new metro stations. The Sydney Metro City & Southwest project, the biggest public transport project in Australia, is a 30km rapid transit project that involves the extension of the Metro North West Line from Chatswood to Bankstown via the Sydney central business district. It is scheduled for opening in 2024.
The Barangaroo Station project is expected to generate approximately 300 jobs during the peak construction phase.
The station is being developed 30m below the northern end of Hickson Road and south of Munn Street in Millers Point. Accessibility to the new station will be through Central Barangaroo and Barangaroo Reserve.
In addition to the construction of the new station, the project will involve building a station entrance next to Nawi Cove and delivering upgrades to Hickson Road, including safety features for pedestrians and cyclists, as well as lifts and escalators to access the station platforms. It will deliver new pedestrian footpaths, lighting, trees, bike parking spaces, street furniture, and a new cycle link at Nawi Cove and along Hickson Road.
Situated 10m above the rail track level, the station’s concourse is split into three main areas, north, south, and central. The crossover cavern at the new underground metro station in Sydney will facilitate the crossing of trains from one track to another.
The Barangaroo station will include new bike parking, bus stops near the entrance, kiss and ride and taxi facilities. Wayfinding signage and information systems will also be installed.
Tunnelling and station excavation works at the Barangaroo station site began in October 2019. Some of the major construction works include launching and supporting the tunnel boring machine (TBM) under Sydney Harbour to Blues Point which will serve as a temporary retrieval site. Cutter heads and shields of the two TBMs used for tunnelling from the Marrickville dive site will also be retrieved.
Ongoing works as of March 2021 include the construction of stairwells and concrete structures to house operational systems for the new station and metro trains, along with the reinstatement and landscaping of the Barangaroo foreshore.
Construction works to retrieve TBMs Nancy and Mum Shirl began in February 2020, after the completion of 8.1km of twin metro tunnels from Marrickville.
Completed by 15 March 2021, the excavation stage of the project involved the removal of approximately 650,000t of dirt and rock. The deliveries of oversize precast beams began in March 2021. Made up of steel-reinforced concrete, the beams will form the cover of the new station.
The project will move to the next stage of construction that will involve the station fit-out from October 2021.
Passengers will be able to reach Barangaroo within 44 minutes from Rouse Hill, 24 minutes from Epping, 26 minutes from Belmore, and three minutes from Victoria Cross Station, upon the opening of Barangaroo metro station in 2024.
The project will improve access to the Walsh Bay Arts and Cultural precinct. It will also facilitate better access to surrounding commercial, residential and entertainment areas and the ferry hub.
Furthermore, the new station project will deliver improved pedestrian connections to the northern part of Sydney’s central business district (CBD) and The Rocks. It will address congestion issues at Wynyard and Martin Place stations.
Sydney Metro teamed up with Infrastructure NSW to deliver the Barangaroo Station project.
BESIX Watpac was awarded a contract to build the new metro station at Barangaroo station, develop an entrance near Nawi Cove, and upgrade Hickson Road in March 2021. The contractual scope includes the construction of underground station platforms and complete fit-out, station entrance, pedestrian and cycling facilities, nearby roads, tree planting, lighting, footpaths, and street furniture.
John Holland CPB Ghella (JHCPBG) worked on the concourse level of the station in December 2020. It is responsible for constructing the 15.5km-long twin railway tunnels between Chatswood and Sydenham and the excavation of six new metro stations under the Sydney Metro City & Southwest project.
Systems Connect, a joint venture between CPB Contractors and UGL Engineering, is fitting out the under harbour tunnels with rail, power, signalling and communication systems.
Ashurst, a global law firm, advised Sydney Metro on the Barangaroo metro station project, while Arcadis provided the excavation and tunnel station design.
