The challenge

As part of the Sydney Metro Project, Arcadis was engaged to provide wide-ranging engineering services to the North West, City and Southwest and West sections of the project over a period of six years, including a new underground station design providing greater public access to the historically significant Headland Park and Walsh Bay cultural precinct and direct access to commercial and residential zones.

    Particularly challenging was Arcadis’ delivery of Sydney’s flagship underground metro station design, Barangaroo, a new state of the art customer-centric metro station set to transform the travel experience for Sydney rail transport users. The construction of Barangaroo station will also aid growth of the current Metro Sydney network by providing capacity for long-term demand to serve and stimulate urban, economic development.


    In addition to providing improved public access, the sustainable design approach for Barangaroo station needed to create a station in Sydney that would become a destination in itself. An exciting and functional hub delivering a positive and vibrant transport experience for the thousands of people living in South and North West Sydney who would rely on the Barangaroo transport hub to connect them to the metro network. The design for Barangaroo would put the transport user first, creating an environment that made it simple and intuitive to navigate the train system in a safe and uncluttered environment.


    As well as all aspects of the detailed design, Arcadis was also responsible for managing the stakeholder process from contractor coordination through to AFC documentation and construction support.

The solution

Arcadis began its journey with Sydney Metro on Northwest (Stage 1) of this major public transport project. Firstly, by providing design and construction phase services to the D&C Contractor, for the Tunnel and Stations Civil Works, Arcadis supported the project getting up and running and on time. Responsible for the detailed design of the deep excavation supports at each underground station, Arcadis’ high-quality and timely design allowed expedited access for the tunnel boring machines, enabling construction to finish ahead of program.

Arcadis’ Independent Assurance team, were engaged to provide independent certification of the Stations, Viaducts and Civil (SVC) works, and in doing so ensured that the first stage of Sydney Metro was certified, and delivered safely and able to be opened to the community.

    On City and Southwest, Arcadis began by delivering Environmental Planning Approval Services, enabling project approval to be gained as planned. The team developed a detailed knowledge and understanding of the technical and environmental challenges for construction under densely populated urban areas, including crossing Sydney Harbor.


    Located almost 25 meters underneath the northern end of Hickson Road, the detailed design of Barangaroo Station would need to meet the specific requirements of multiple stakeholders with a shared vision of putting the customer at the center of all project outcomes, including a station entrance within the extended parkland vision.


    Engaged as part of a Design Joint Venture in a D&C for the Tunnel and Station Excavation phase of the project, Arcadis provided detailed, finished designs for the deep excavation stations works, ensuring construction safety in a dense urban environment. During this phase of delivery, Arcadis used innovative 3D digital modelling combining civil, drainage, utility and structural elements to visualize the site constraints and ensure there was no impact on existing utilities.


    Drawing on Arcadis global expertise in digital innovation, Arcadis’ design team delivered Underground Stations Design and Technical Services (USDTS), a package of six new stations on the City & Southwest line. Arcadis, as part of a design joint venture, challenged the space planning of the underground stations and delivered solutions that provides better customer centric outcomes. At Barangaroo Station, Arcadis used 3D modelling of and virtual reality to place contractor partners and stakeholders, including customers, in a virtual underground station, encouraging them to interact in the imagined space. The feedback and insights from this experience brought diverse community perspectives to the project, highlighting the unique requirements of the station design, underpinning one of the most important goals of the project – to put the public transport user first. Arcadis used feedback from the virtual experience to deliver complex designs through multi-discipline design teams across Australia, United Kingdom, Netherlands, Philippines, India, Hong Kong, and Singapore.


    As a major business center, North Sydney required a station that would not only quickly connect commuters to the CBD, but also provide a commercial and retail hub that would unlock the economic potential of it. On Victoria Cross Integrated Station Development, Arcadis are working collaboratively with Lendlease to design and deliver the Station, the local precinct area, and the Over Station Development.


    The final aspect that will complete the City and Southwest line, is the conversion of the current Bankstown Line, to metro. Arcadis provided detailed designs for the Southwest Metro, requiring a complex design approach to convert the existing rail line and stations with significant heritage constraints into a modern metro line that will benefit the local communities with greater reliability, ease of use and increased frequency of trains.


    Respecting the cultural and historical significance of the natural environment, the Arcadis team also focused on a sustainable design approach that respected the Aboriginal origins of the land and local heritage of the area.


    In 2019, Arcadis commenced work on the Sydney Metro West project, once again delivering Environmental Approval Services.

The impact

As the largest public transport transformation project in Australia’s history, the delivery of the Sydney Metro City & Southwest project will change the way people experience public transport in Sydney.

    As a stand-alone rail network, the Sydney Metro will clear the city’s public transport bottlenecks and meet its goal of giving people more time in their day to enjoy the spectacular city of Sydney and all it has to offer. By creating a clutter-free station environment and designing the stations as close to the surface as possible, people will be able to enter and exit the station with ease. Increased reliability of services and implementing several Australian-firsts including fully automatic driverless, single deck metro style trains and automatic platform screen doors will also improve safety and convenience. Increased rail capacity, improved travel times, reduced train and station crowding, increased rail network reach, improved bus conditions for bus customers, and less congestion for road users will also drive positive experiences for people moving across the city by rail and road. There will be an ultimate capacity for a metro train every two minutes in each direction under the Sydney city centre by the completion of the metro rail and metro tunnel project in 2024.


    Arcadis’ sustainable and considered design approach also achieved Green Star 5* rating for Sustainability, improving the quality of the transport experience for customers and enhancing Sydney’s reputation as a world-class city with a public transport system in line with the great, innovative systems around the world.
