Renovation experience
”We have just finished the renovation of the central railway station in Copenhagen with great success and can use many of our valuable experiences from this assignment for the assignment at Nørreport Station” says Arne Buhl Petersen, division manager of Grontmij in Denmark. “This is also one of the reasons that we have won the assignment, in addition to the fact that we can offer a dynamic project organisation capable of carrying out the necessary planning and risk management of the total project.”.
Replacement of membrane
The replacement of the membrane in the tunnel tube is the main renovation in the project. This membrane keeps the water out of the tunnel tube and has worn down after doing its job for almost 100 years. Furthermore, the section joints and internal support structures must be checked and renovated, in order for the entire structure to be well-maintained and functional again. Road and pavement surfaces as well as cables in the area must be dug up to make room for laying out the new membrane.
Minimising disturbance
The work on the area will take place in stages with the utmost consideration as possible for the many road users and citizens that have to be in the area. Every day, more than 78,000 travellers pass through the area. The work in the tunnel tube will be carried out at night in order to minimise traffic disturbance.
Tough competition
Grontmij in Denmark has been given the assignment in tough competition with several large Danish engineering companies. Feasibility studies and project planning have already begun and the repair work is expected to be carried out during the period from 2011 to 2014.
Coordination
The extensive work must be coordinated with two other projects that are carried out at the same time in the same area. These projects are the Danish Public Transport Authority’s modernisation project for the Nørreport Station, which has the purpose of ensuring better air quality on the long-distance train platform and renovation of the facilities visible to passengers. The other one is the Copenhagen Municipality’s project for a new urban space around the station, which will be settled through an architectural competition that will be published on the 3rd of November this year.
