Martin Place Integrated Metro Station Development, Sydney

A new level of integrated station development in the heart of Sydney’s CBD

In collaboration with architects Grimshaw, Johnson Pilton Walker (JPW) and Tzannes Associates, Arup has supported Macquarie Group’s proposal to the New South Wales Government to design and construct Metro Martin Place – a world class, fully integrated transport-initiated mixed-use development. It will be the first of its kind in Australia.

The development in the historic Martin Place - the civic centre of Sydney - is adjacent to the Group’s present global headquarters and includes two new major commercial buildings and an expansive Metro station which will link with the existing rail station. The proposal links Martin Place and Hunter Street, as well as Martin Place Railway Station and Martin Place Metro Station providing a new transport hub, city attraction and economic precinct for Sydney’s CBD.

As the multidisciplinary consultant, Arup worked closely with Macquarie and the NSW Government from inception to give confidence that this ambitious engineering challenge was feasible, while bringing real economic and social value to Sydney.

The 170-strong Arup team brought together specialists from more than 40 disciplines with first-hand experience on iconic global integrated transport developments such as 2nd Avenue Subway Station, NYC, Crossrail, London and Copenhagen Metro.

With the NSW Government and Macquarie having achieved commercial close, Arup appreciates the opportunity to meet the challenges of taking a central role in the detailed design and delivery as the lead engineering consultant to the Managing Contractor, Lendlease.

And, as the lead engineer, Arup will continue to work closely with Macquarie, Lendlease, Grimshaw, JPW and Tzannes Associates to deliver the project – one that will set the standard for transport precincts for many decades to come.

This project is uniquely located in the very heart of the Sydney CBD, connecting history with commercial and civic activity. With the NSW Parliament House at the eastern end of Martin Place on Elizabeth Street, the presence of the Cenotaph, and the wide pedestrian boulevard framed by buildings such as the grand General Post Office, the development will become a pivotal destination in Sydney’s banking and commercial centre.

Arup joined Macquarie’s project team in January 2016 as the lead engineer. The proposal successfully progressed through three stages of the NSW Government’s unsolicited proposals framework, demonstrating its uniqueness and ability to provide real and tangible benefits.


We’ve been working for Macquarie on this project since the beginning, and we’re thrilled to see it take another step forward. Following the role we played in developing Macquarie’s award winning development at 50 Martin Place to seeing it take its place in an integrated precinct is such a great outcome. We are now focussing on delivering this unique project with our architectural and construction partners. ” Andrew Pettifer Andrew Pettifer NSW Region Leader

This project is an example of the future of people movement in metropolitan areas. As stages of the new Sydney Metro network are delivered, it will form a fully automated metro system, carrying up to 400,000 people daily and transform the way Sydney moves and operates as a modern and growing global city.

The integration of the design of the public and private spaces facilitate benefits that might not have otherwise been possible. It improves access for metro customers and other users throughout the station precinct, significantly increasing public concourse space and enabling greater connectivity and access to amenity and retail.

From an engineering perspective, the scale of this project hasn’t been seen in Australia before so we’ve brought our people in from all over the world. Our designers, engineers and planners have worked on iconic developments overseas, such as 2nd Avenue Subway Station in NYC, Crossrail in London and Copenhagen Metro. It’s wonderful to be able to bring this level of global knowledge to Sydney, and the team will bring the design to life over the next few years. ” Marianne Foley Marianne Foley Australasia Consulting Leader

Arup’s expertise in combining transport engineering and premium tower design is key to creating a precinct for Sydney that is designed to engage and inspire. By weaving together transport infrastructure, public realm, activated retail and premium grade commercial towers, the development seeks to maximise space, light and activated connectivity to deliver a unique and well-rounded experience for its users. The design offers natural light down towards the platform level, and shows what can be achieved when design and functionality are well integrated.


This is a once-in-a-generation opportunity for Sydney. Arup has worked on integrated over-station developments all over the world but we’ve not seen transport, public realm and commercial melded in this way before. It’s really exciting to be a part of such a unique project. This is a complex and exciting proposal, and we now look forward to delivering it. ” David Harding David Harding Leader - Transport Developments

The engineering challenges presented by the constrained CBD site, existing rail tunnels under the south tower and the heritage building at the heart of the site were managed by undertaking detailed modelling of the ground conditions at each stage of construction. Arup will continue to oversee the works as the design and construction develops.
