Contract for "Sisikon Tunnel", lot 200 of the "Neue Axenstrasse" project, is
awarded to joint venture led by Implenia | Total order worth more than CHF
430 million, Implenia's share worth over CHF 250 million

Glattpark (Opfikon), 28 June 2024 - The cantons of Schwyz and Uri have
awarded the contract for lot 200 of the "Neue Axenstrasse" project - the
"Sisikon Tunnel" - to a joint venture (JV) between Implenia and Frutiger
(Implenia 60%, Frutiger 40%). Its size and complexity make this lot the
focal point of the new road running along the eastern shore of Lake Uri/Lake
Lucerne. Worth more than CHF 430 million as a whole, Implenia's share of the
contract comes to over CHF 250 million.

The contract centres on the single-tube, 4.4 km two-way road tunnel, which
the JV will blast through the rock. The JV is also building various other
underground structures such as access tunnels, passing places, ventilation
hubs and exhaust ducts. With up to seven simultaneous tunnelling points and
very tight space conditions, the job presents some unique challenges.

Contract confirms Implenia's expertise in large, complex transport
infrastructure
In addition to the tunnelling, various external works are being carried out
by other Implenia civil engineering units, including the construction of a
large gallery to protect against natural hazards. Around 2 million tons of
excavated material will be produced by the various construction projects,
most of which will be taken away by boat to a large renaturation project on
the Reuss Delta in Flüelen.

"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," says Christian
Späth, Head Division Civil Engineering at Implenia.

The order is subject to a consultation period lasting until the end of July
2024. Construction of the lot is scheduled to start in mid-2025, and the
work should be completed by 2034.
