Challenge

Rapid population growth and shifting travel patterns have put mounting pressure on Melbourne’s existing rail corridors. With the City Loop nearing capacity, the network cannot accommodate more trains in and out of the city. To maintain a high quality of life in Australia’s fastest-growing city, Melbournians needed a new way to move across their city. The Melbourne Metro Tunnel project was conceived to meet this challenge.

 

Solution

Arcadis is working with consortium CYP Design and Construction (CYP D&C)—led by Lendlease, John Holland, and Bouygues—to deliver the Tunnels and Stations package of the $11 billion Melbourne Metro Tunnel, Victoria’s biggest ever public transport infrastructure project.

In a joint venture with Arup and WSP, Arcadis is delivering the detailed design to support CYP D&C in designing and constructing the Metro Tunnel’s twin nine-kilometer rail tunnels and five new underground stations.

This scope includes civil engineering, structures, mechanical and electrical, rail infrastructure, fire and life safety engineering, security and blast assessment, pedestrian modeling, vertical transportation, specialist lighting, sustainability and digital solutions, as well as noise, vibration, and acoustics.

Impact

The Metro Tunnel project will create a new end-to-end rail line from Sunbury in Melbourne’s west to Cranbourne/Pakenham in the south-east with high-capacity trains and five new underground stations. This will provide the network capacity to enable more than half a million additional passengers per week to use the rail system during peak periods.

Additionally, the stations will set a new benchmark in design, delivering five new architectural landmarks for Melbourne.
