Pöyry awarded engineering contract on Follo Line

Norway Societá Italiana per Condotte D'Acqua S.p.A. has chosen Pöyry to carry out rock and tunnel engineering for the Follo Line in Oslo, Norway, the consulting and engineering firm announced on January 25.

The Follo Line connects Oslo with the city of Ski in the east-bound Follo district. Pöyry's assignment includes most of the design needed for 5.5km of tunnels close to the city centre of Oslo, 4km of which is for high-speed train traffic.

Condotte is the EPC contractor for which Pöyry is engineering, and the end client is the Norwegian National Rail Administration. The tunnel will be excavated using drill and blast and drill and split methods. All engineering will be carried out as Building Information Modelling (BIM).

According to Pöyry, the project includes some unique challenges, such as the existing underground facilities and the relocation of the underground river Alna.

"This is the first large transportation engineering assignment we have won in Norway. Our experts in Norway and Finland are working jointly to tackle the challenges of the assignment in an innovative and reliable way that is characteristic to our work," said Mikko Inkala, president of infrastructure design at Pöyry.
The value of the order is not disclosed. The order has been recognised within the Regional Operations order stock in Q1 2016.

The Follo Line tunnel system will be the longest in Norway with a total length of 20km and a maximum train speed of 250km/h. It will meet the increased demand for rail traffic capacity caused by the growing population in the greater Oslo area, and will serve an estimated 150,000 passengers daily after its completion by the end of 2021.
