Review of Hagenholz tunnel/“The Circle” at Zurich Airport

Project overview

In its final state, part of the new “The Circle” complex at Zurich Airport will stand above the existing Hagenholztunnel and the duct between the heating centre and the freight facilities. The change in load on the support structures calls for a static review and the planning of any necessary measures.
