AECOM to provide detailed design services to support delivery of Sydney Metro West

DALLAS–(BUSINESS WIRE)–AECOM (NYSE: ACM), the trusted global infrastructure leader, today announced it will deliver detailed design services for the Sydney Metro West Line Wide Systems package in a joint venture with WSP, supporting John Holland, the project lead and contractor. Sydney Metro West is a transformative project that is expected to double rail capacity between Parramatta and Sydney CBD, providing Sydney with fast and reliable transportation and aiding the city’s rapid growth.

The joint venture will lead the design of the 24-kilometer twin-bore tunnel fit out, a new metro train depot and service facility, a new metro traction power system and tunnel ventilation system, and the train systems, operations and maintenance package.

“Sydney Metro West will play a vital role in shaping a more connected, livable Sydney, delivering faster, more reliable journeys for communities now and into the future,” said Mark McManamny, AECOM’s chief executive for its Australia New Zealand region. “AECOM is globally recognized for our ability to deliver rail systems at this scale, and we’ll apply AECOM’s depth of expertise from Australia, New Zealand, the United Kingdom, Europe and Hong Kong to deliver a safe, reliable and sustainable metro for Sydney.”

AECOM is delivering a better world through the application of cutting-edge digital technologies. On the Sydney Metro West project, the joint venture’s advanced digital delivery approach will guide the design and management of this complex, major rail system. The project will feature fully automated modelling for the tunnel fit-out systems, enabling efficient updates and seamless integration across the long linear rail network and the containment infrastructure, spanning the two 24‑kilometer tunnels. A collaborative digital design environment will be implemented to enhance coordination across design offices in Australia, New Zealand, Europe and Asia, enabling seamless stakeholder reviews and efficient feedback resolution.

“We are proud to support the delivery of one of Sydney’s most complex and impactful transportation projects,” said Mark Southwell, chief executive of AECOM’s global Transportation business. “Our unmatched technical excellence, approach to innovation, and deep history of delivering transformative infrastructure in Sydney make us ideally positioned to deliver on this project, and these advantages are part of why AECOM remains Engineering News-Record’s number one transportation firm in the world.”

The appointment as designer for the Sydney Metro West Line Wide Systems package builds on AECOM’s track record of successfully delivering on large, complex rail systems in Australia and New Zealand, including the recently opened Metro Tunnel in Melbourne, the METRONET in Perth, and the soon-to-open City Rail Link in Auckland.
