CITYRINGENFACT SHEET

Four hundred years after Christian IV ordered the construction of Christianshavn to extend the fortifications of the city, Copenhagen has overseen another mega infrastructure project which reshapes the urban space: Cityringen, the new metro line that will help it in its bid to become the greenest capital in the world. The project, commissioned by Metroselskabet, the public entity responsible for the metro network, was designed and built by Salini Impregilo via a local entity called CMT.

Thanks to the new line and its connections to the existing network, residents will be able to move by foot, bike or public transport for 75 percent of their trips.

Cityringen encircles the heart of Copenhagen with two parallel 15.5-kilometre-long tunnels. It passes under the historic centre, the so-called “bridge quarters”, as well as the independent municipality of Frederiksberg, which is located within Copenhagen’s borders. The line has 17 underground stations situated an average 30 metres below street level. Driverless and completely automatic trains pass every 100 seconds and as little as 80 seconds at rush hour.

INNOVATION AND TECHNICAL HIGHLIGHTS

One of the greatest challenges of building Cityringen was having to do it in

Since the line crosses some of the Danish capital’s most densely populated neighbourhoods with commercial and historic areas, great effort was made to carry out the work without disrupting people’s lives or damaging any buildings.

The TBMs – tunnel boring machines - excavated 31 kilometres under the streets through different and, at times, difficult geology. They even managed to pass within

The excavation was carried out using innovative techniques. The TBMs did the tunnels 4.9 metres in diametre at an average depth ranging from 20 to 35 metres.

THE SUSTAINABILITY CHALLENGE

City’s HeritageCityringen opened up a veritable treasure trove for researchers at the Museum of Copenhagen, enabling them to learn more about the Danish capital’s past. As workers excavated tunnels and station boxes for the new metro line archeologists uncovered remnants of life dating back nearly a millennium.

At the early stage of its development, Cityringen proved to be a veritable treasure trove for the

Museum of Copenhagen, which described the new metro line’s

various work sites as the “greatest archaeological

excavation in Northern Europe”.

Amid the excavations at places like Gammel Strand and Radhuspladsen, they uncovered everythingfrom pottery to textiles and building foundations to bulwarks

from an old harbour,giving them greater understanding of the Danish capital’s past.

more than40 public eventsin the worksites

more than65,000 visitors

PeopleCityringen was built by people from 24 countries, including England, Ireland, Romania, Italy, Bulgaria and Portugal. It was an example of multicultural Europe that not only created thousands of jobs but also displayed the highest level of technical skill in the industry.

EnvironmentThe project oversaw the clean-up of previously contaminated soil in a number of areas. A careful management of chemical substances avoided infiltrations in the water table and an advanced monitoring system ensured that materials used on the project were compliant with environmental regulation. Wherever the contaminated soil was found, a process to treat and remove it was implemented with the greatest care.

SafetySpecial attention was given to health and safety on the work sites with the adoption of the best international practices and the organization of several awareness campaigns. The result was that in the end of 2018 the entire Cityringen project celebrated the achievement of one million working hours without a single accident, becoming best practice throughout the country.

Local Community Engagement Local communities were involved in every phase of the project with the aim of fomenting greater understanding of the complexity of the work and the benefits to be gained from it once completed. Many information

campaigns were organised to engage local communities, inviting members to visit the worksites to learn about the technology and techniques used and witness the progress of the project.
