Government Contracts

Vienna - A consortium of Austria's two largest construction companies, STRABAG
and PORR, has won the tender for the first phase of the largest connected
construction project of Wiener Linien, the Vienna public transport provider. A
total of 7 km of tunnel will be driven and four new stations built as part of
the redirection of the U2 line. The contract value for the consortium - in which
each party has 50% - is around half a billion EUR. Construction is set to begin
in February 2021 and will run until mid-2028.

"Construction work in the inner-city is always a challenge in light of the
cramped conditions. Drilling beside the facades of the nearby buildings requires
a great deal of expertise and transport to and from the sites through the narrow
alleyways surrounding Neubaugasse is exceptionally complex in terms of
logistics", says Thomas Birtel, CEO of STRABAG SE.

Significant upgrade to public transport coverage

The expansion of the inner-city metro network network is a huge milestone in
Vienna's urban development. Enhanced performance, direct links for travellers,
and significant benefits for the environment all characterise the Wiener
Linien's most important future-focused project. "This key infrastructure project
definitively closes the gaps in the inner-city metro network for Vienna. With
our decades of experience and exceptional technology knowhow in underground
railway construction, we will play a key role in sustainably improving Vienna's
public transport infrastructure", says Karl-Heinz Strauss, CEO of PORR.

Under the metro expansion, the U2 line between Karlsplatz and Rathaus will
become part of the U5, while the U2 will branch down towards the south of the
city. The contract is part of the first construction phase of the U2/U5 line
expansion in the Austrian capital. This includes the phases U2/17-21 (U2/17
driven by TBM, U2/18 Matzleinsdorferplatz station, U2/19 Reinprechtsdorfer
Straße station, U2/20 Pilgramgasse station and U2/21 Neubaugasse station).

Tunnelling team to work around the clock

The demanding construction of the two tunnels in the inner-city area will
require the tunnelling team to work around the clock in shifts. Around 4 km will
be driven by a tunnel boring machine (TBM), while another 3 km will be bored
using the New Austrian Tunnelling Method (NATM). All of the works such as
tunnelling, structural engineering, ground engineering and railway construction
will be rendered autonomously by the consortium.

The stations are being built using the cut-and-cover method of construction,
with the station shafts up to 40 m wide and 50 m long. This means that the
excavation for the stations, which lie at a depth of up to 40 m, must first be
secured by means of drilled piles and internal steel stiffeners and then worked
downwards floor by floor. The station shafts themselves are also the central hub
for the delivery and removal of the material.
