FINISH OF THE WORK IN TUNNEL

New lifts for Copenhagen Central

Delivery and installation of 9 lifts 

 

Aarsleff Rail has installed respectively 6 and 3 lifts at Copenhagen Central and Østerport Station for the Copenhagen Metro. The lifts allow passengers to easily change between trains and metro at Copenhagen Central and Østerport Station once the new Metro-Cityring opens in 2018/19. The new lifts on Copenhagen Central  connects the platforms with the existing passenger tunnel, which will later be connected with a tunnel to the future metro station west of the central station. At Østerport Station the lifts connects the existing steel bridge with the platforms.

Extensive work

The project comprised a wide range of disciplines because of the lifts’ challenging locations. We established construction shafts with steel sheet piling, handled earth and concrete works, break down of old concrete structures to create a connection between lifts and passenger tunnel and an extensive handling of ground water. For several of the tasks we utilized specially adapted railway vehicles and for the installation of the lift towers we used our railway crane. We installed the lifts, paved the platform surroundings, made the necessary catenary changes and readied the lifts for service.

The ground water handling included refiltration of ground water to maintain an unchanged water level for the entire Central Station area and surroundings during the work.

 

Demanding logistics

As both stations were in full service during the construction period, logistics and security was a challenge. The area available for work was limited and piling took place just 1.6 m from the platform front.  In addition the work was defined by tight track possessions and we carried out most of the work in weekends. After every possession the platforms were left cleaned up and the work area sealed off.  

 

We carried out the contract in 52 weekends and every lift was ready for service as the deadline was reached.
