We build Sydney

Booming economic metropolis, popular tourist destination, rapidly growing multicultural city—Sydney’s appeal poses big everyday challenges towards the infrastructure of the oldest and biggest city in Australia. The metropolis with a population of five million inhabitants and yearly 16 million visitors is according to surveys nevertheless one of the most liveable cities in the world. Because Sydney has found—with the support of HOCHTIEF subsidiary CIMIC—transport solutions that are sustainable and affordable, that optimise metro and motorways, and promote public and active transport.

The expansion of local public transport around Sydney is characterized by superlatives: Sydney Metro is the largest project in the Australian public transport network, the first fully automated metro rail line in Australia and has some of the the longest railway tunnels in Australia. When completed by CIMIC and its partners, the 31 station, 66 kilometers long network will connect dozens of suburbs and thousands of commuters to the Sydney central business district (CBD) faster and more comfortably every day.

Project overview:

  • Final completion: 2014 to 2034
  • Investment, Design, Construction, Supply, Systems, Operations, Maintenance

Fast commuting—on land and under water

Sydney Metro connects expanding regions with the city.

At Metro Northwest’s 13 stations, services currently operate every four minutes in the peak with the driverless trains in each direction passing through twin 15 kilometres tunnel

Sydney Metro Northwest opened in May 2019 on time and AUD 1 billion under budget.

Stage 2 is extending the metro line under Sydney Harbour, through new underground city stations and beyond to the southwest, opening in 2024.

Sydney Metro will have ultimate capacity for a metro train every two minutes in each direction under the city. Sydney’s new metro railway will have a target capacity of about 40,000 customers per hour, similar to other metro systems worldwide.

The rapidly growing metropolis of Sydney is an important junction for road, sea and air traffic and freight. In order to relieve roads and avoid traffic jams, the WestConnex motorway project will in future connect the west and south-west of Sydney with the city, its airport and port. At 33 kilometers long, the motorway is Australia’s largest urban road project. CIMIC is gradually completing its work in four stages.

The project at a glance:

  • Completion:
    • Stage 1, 2: 2017/2019
    • Stage 3: 2020
    • Stage 4: 2023

West Connex’s first phase of construction, widening the M4 from six to eight lanes, was completed in 2017.

The M4 East project extended the M4 by 6.5 kilometres — with 5.5 kilometres tunnels between Homebush and Haberfield, and was officially opened for traffic in 2019.

This will improve the flow of commuters on the M4 East to and from the Parramatta business district.

The new M5 will run via twin tunnels from a new junction in St. Peters to the existing M5 East in Kingsgrove. This will open in 2020 and double the current traffic capacity. East-west access between Sydney, Port Botany, the airport site and the southwest growth areas will also be significantly improved.

CIMIC is also delivering the M4-M5 Link – Rozelle Interchange which will connect the M4-M5 Link Tunnels to the surrounding road network and future Western Harbour Tunnel. The interchange will open to traffic in 2023.

177 Pacific Highway

State-of-the-art architecture is characterized by one thing above all: sustainability. The 177 Pacific Highway building has a lot to offer: 5 stars in the Australian “Green Star” rating and 5.5 stars in the NABERS energy rating. But the office tower, which was built by CIMIC, also looks great.

The project at a glance:

  • Completion: 2016
  • Floors: 30

Northern Beaches Hospital


As the population grows, social infrastructure in Sydney also needs to be expanded. The Northern Beaches Hospital in the north of Sydney, which was built by CIMIC on a green field site, does a very good job here: With a capacity of 488 beds on an area of 70,000 square meters, it offers not only large scale, but also first-class, state-of-the-art health care for the local population.

Project overview:

  • Opened: 2018
  • Size: 70,000 square meters
  • Capacity: 488 beds, 14 operating theaters

Wynyard Walk

A pedestrian tunnel and bridge, elevator and escalator take you from the central business districts Wynyard transport hub to Barangaroo harbourfront development in just six minutes—the architecturally spectacular Wynyard Walk in the heart of Sydney makes it possible. Seamlessly seperating people from traffic, avoiding step inclines and road crossings, the Wynyard Walk shortens walking time from fifteen to six minutes, with capacity for up to 20,000 pedestrians per hour. CIMIC completed the 180 metres long footpath in 2016.

The project at a glance:

  • Completion: 2016
  • Length: 180 metres

A sustainable short cut as an experience

Thanks to Sydney’s environmentally friendly connection with Barangaroo, the Wynyard Walk creates a sustainable piece of infrastructure in the middle of the city.

The Napoleon Plaza is the heart of the walk and connects the pedestrian tunnel directly with the ground floor via steps, elevators and escalators.

The huge “Wynscreen” at the entrance to the station provides entertainment: it combines art, culture and LED technology.

Wynyard Walk is “green”: natural daylight is supplemented by LED light strips, and materials used have been selected according to environmental performance and can be recycled.
