Utvidelse av Oerlikon stasjon

The Oerlikon Train Station Expansion Project is part of the larger SBB initiative to improve the Zurich cross-city link. This undertaking involves extending Oerlikon station by adding two new train tracks and a 150-metre-long retaining wall to increase capacity. Additional modifications include the renewal of the Schaffhauserstrasse bridge, the enlargement of pedestrian access routes and underpasses, and the introduction of new retail spaces in the underground commercial center.

Kompleks konstruksjonsprosess

The construction process for the project is significantly complex. The excavation pit is supported by an anchored retaining wall and shotcrete, with non-tensioned anchors in the head sections. The new bridge’s static loads are transferred through bored piles, while temporary loads are directed into the ground using micropiles. Jetting columns were employed to brace the excavation pit and enhance the structural stability of the existing bridge abutments.

Spesifikke byggetjenester

Specific construction services for the project included the installation of 3,000 meters of DN 1,000 bored piles, 2,000 meters of support drilling with HEB profiles for the retaining wall, 800 meters of micropiles, and 10,000 meters of pre-tensioned anchors along with 200 non-tensioned anchors. Additionally, 250 meters of jetting columns and 2,000 meters of shotcrete were used for embankment securing.

Utfordringer og gjennomføring

One of the prominent challenges of the project was executing the construction work during ongoing railway operations and within a very confined space. Despite these difficulties, the project, which had a construction volume valued at 10.9 million CHF, was successfully completed from January 2012 to January 2016.

Prosjektledelse og samarbeid

The project was managed and designed by Ingenieurgemeinschaft SLW+Partner, with the contracting entities being ARGE Gate Oerlikon c/o Implenia Schweiz AG and Kibag AG. The building owners are SBB and the city of Zurich, demonstrating a collaborative effort between public and private sectors to enhance urban infrastructure.
