Specialist for challenging infrastructure projects in Europe
The Segment Infrastructure focuses on tunnel construction and foundation engineering in all national markets. It brings together Implenia’s expertise in tunnelling, foundation engineering, large-scale projects and design/planning, giving the Group a strong technical platform to exploit the opportunities presented by the “infrastructure” megatrend. The Segment Infrastructure offers its services in Implenia’s home markets of Switzerland, Germany, Austria, Norway and Sweden, though it also bids for large, complex European infrastructure projects outside these markets.

Infrastructure

  • Very good results above expectations
  • Major projects gather momentum and go into production
  • Markets in good shape
  • EBIT excl. PPA

The Segment Infrastructure includes Implenia’s pan-European Tunnelling and Foundation Engineering capabilities. The segment achieved a very good result and exceeded expectations during the year under review. On a like-for-like basis, operating income came to CHF 19.1 million, which is 32.2 percent up on the previous year (2016: CHF 14.5 million).

Strong operating performance

Even after including amortisation costs for intangible assets assumed as part of the Bilfinger Construction acquisition, the operating result in 2017 still came to CHF 14.4 million, underlining the segment’s strong operating performance. The broad-based income trend vindicates the internationalisation strategy adopted for infrastructure business. Various large-scale projects in the segment gained momentum in the second-half of the year and, following initial delays, are now going into production.

As well as in Switzerland, Germany, Austria, Norway and Sweden, the segment is also active in France. Implenia Infrastructure is well positioned in the market and is working on various mega projects, including the Albvorland Tunnel on the new railway line between Wendlingen and Ulm, two sections of the Semmering Base Tunnel, and two sections of the “Grand Paris Express”.

At end of the year, order books were worth a total of CHF 1,341 million after CHF 1,524 million in the previous year.

Bözberg Tunnel

Key projects

Bözberg Tunnel

A 4-metre corridor is being added to the Gotthard axis in order to encourage the shift of transalpine freight transport onto the railway. The largest sub-project within this overall plan is the replacement of the existing Bözberg Tunnel in Canton Aargau with a new twin-track tunnel. Swiss Federal Railways (SBB) has commissioned Implenia to do the main construction work. The main drilling is being done with a tunnel boring machine that has a diameter of 12.36 metres, and that can advance by up to 40 metres a day. The tunnel should be ready for operations in 2020. This strategically important job underlines Implenia’s capabilities as a general contractor for infrastructure construction.

Überseequartier building pit, Hamburg

Implenia has been asked to create the biggest building pit in Hamburg for the new “HafenCity” development. The work includes erecting diaphragm walls, some back-anchored and some braced, against the mica clay in preparation for three basement floors, as well as building a link to the new metro using sealed piles and jet grouting. Significant challenges at this landmark project include the existing buildings (quays, metro structures) and the contaminated ground, owing to previous development. The subsequent development planned by client Unibail-Rodamco includes eleven buildings, with space for hotels, restaurants, offices, homes and a new cruise ship terminal.

Albvorland Tunnel

Implenia has been commissioned by Deutsche Bahn to build the Albvorland Tunnel, a key section of the new 60-kilometre-long railway line between Stuttgart and Ulm. Drilling work on the tunnel, which will be more than eight kilometres long, began in October 2017. The two single-track tunnels, each with a diameter of almost 11 metres, are being drilled out in parallel by two tunnel boring machines. Around 54,000 tubbing elements are required to line the tunnel; to minimise transportation, these are being made at a purpose-built factory in Kirchheim unter Teck. This “One Company” project by Implenia is contributing to the ongoing expansion of Europe’s rail network.

Theresienstrasse building pit, Munich

On a 6,500 m2 plot in Munich, Instone Real Estate Development GmbH is developing a new neighbourhood with 116 owner-occupied homes and a children’s day-care centre. Implenia was responsible for creating a sealed building pit using back-anchored pile walls, which required various drill diameters and drilling techniques. The façade of the adjacent building was secured using birdcage scaffolding. This scaffolding had to be rebuilt several times as the piles were made. The creation of this technically demanding building pit on an inner city site attracted a lot of attention within the industry.
