The contract for lot 200 of the Neue Axenstrasse project in the Sisikon Tunnel was granted to a joint venture (JV) between Implenia and Frutiger by cantons of Schwyz and Uri.
Due to the size and complexity of the project, this lot is one of the focal points of the new road running along the eastern shore of Lake Uri/Lake Lucerne, whereas the contract value is more than CHF 430 million.
With 4.4 km length creation of a single-tube two-way road tunnel is a central part of the contract and the JV will dig via drill and blast methods.
Also construction of other underground structures including access tunnels, passing places, ventilation hubs and exhaust ducts will be up to JV. The challenging job will include up to seven simultaneous tunnelling points in very tight space conditions.
Including the construction of a large gallery to protect against natural hazards, various external works are also being carried out by other Implenia civil engineering units in addition to the tunneling elements.
The quantity of excavated material will be almost 2 million tons that produced by the various construction projects,while most of which are going to be taken away by boat to a large renaturation project on the Reuss Delta in Flüelen.
According to Christian Späth, Head Division Civil Engineering at Implenia: “We and our JV partner Frutiger are very pleased to be building this vital transport link in central Switzerland. The creation of the Sisikon tunnel involves challenging work in a very special location, making it a perfect fit for Implenia’s strategy as a specialist in large and complex transport infrastructure. We will be able to contribute our extensive expertise and experience in tunnel construction and civil engineering.”
While the detrmined deadline for this order that is subject to a consultation period is until the end of July 2024, mid-2025 is the planned date for commencing construction of the lot and the work should be completed by 2034.
