Stockholm Central Station renovation
We carried out the station's renovation contract underground so inconspicuously that the station remained in use throughout the operation.
Nearly a quarter of a million people pass through Stockholm Central Station every day. A part of the building had begun to sink, and its foundations needed renovation.
The station building was constructed in 1871. We carried out the renovation contract underground so inconspicuously that the station remained in use throughout the operation. We developed several new solutions in the course of the contract. For instance, we used a diamond wire saw to cut work holes in the wall in order to limit the noise and vibration caused by the work, and we designed special drill carriages for transferring loads in cramped spaces. The new steel piles were drilled into the bedrock under the old foundations.
