Tunnelling

The new double track railway Sandbukta-Moss-Såstad (SMS) is part of the Intercity development and is one of the sections of the line towards Halden (the Østfold railway's western line).

With a length of 27 km, line 17 extends over 13 municipalities in the departments of Seine-Saint-Denis, Val-d'Oise and Seine-et-Marne. It connects nine stations between Saint-Denis Pleyel and Le Mesnil-Amelot in less than twenty-five minutes and will facilitate the daily life of nearly 565,000 people.

The project comprises the two-lane extension of the Varberg-Hamra section, which is part of the Västkustbanan railway line connecting Göteborg with the southern Swedish city of Lund. As part of an Early Contractor Involvement contract (ECI con-tract), Implenia was initially awarded with the Preliminary Design (Phase 1) in June 2018, and subsequently with the Detailed Design and Construction (Phase 2) in September 2019.

The major project 2nd S-Bahn main line Munich consists of the sub-projects "above-ground areas", "inner city area/tunnel" and "supplementary network measures" in the outer branches.

As the second of four phases of the so-called City Link Project, the Anneberg-Skanstull Tunnel serves to improve the power supply in the Greater Stockholm area. At a length of around 14 km and a diameter of 5 m, the tunnel is being driven about 50 - 100 m below the Swedish capital using a tunnel boring machine.

In order to serve the city center of Oullins, the university-hospital hub of Lyon Sud, to create a multimodal exchange center and globally to intensify the development of the "valley of hospitals", SYTRAL has decided to extend the line B subway about 2.5 km at the south of Lyon. Two new stations will be created, Oullins Center and Saint-Genis-Laval Hospitals South. This work was entrusted to the joint venture IMPLENIA France (Agent) - DEMATHIEU BARD - IMPLENIA Switzerland. This award marks the successful development of Implenia France in the country by engaging in large-scale projects, with major public clients located in the region.

Implenia France, within the ALLIANCE group, has developed a specific production tool for segments (tunnel lining) for the needs of Grand Paris.

The “Grand Paris Express” project aims to improve links between the French capital and neighboring residential areas in the Greater Paris region (Île-de-France) by building a transport network of six driverless underground railway lines by 2030. The project will require 210 kilometers of tunnel and nearly 70 new underground stations. After winning the “Lot GC01” Implenia also got the order to build the extension of the Metro line 15 in the south-east of Paris (“Lot T2C”) in a consortium.

The “Grand Paris Express” project aims to improve links between the French capital and the neighboring residential areas in the Greater Paris region (Île-de-France) by building a transport network of six driverless underground railway lines by 2030. The project will require 210 km of tunnel and nearly 70 new underground stations. It also comprises the extension of the existing line 11 from the station “Mairie des Lilas” in direction to “Rosny Bois-Perrier” in the east of Paris realized in three phases (GC01, GC02 and the viaduct).

The new railway link (NBS) Wendlingen-Ulm together with Stuttgart 21 significantly improves the infrastructure of Baden-Württemberg and thus creates shortened travel and transport times not only in Baden-Württemberg but also across Germany and Europe.

The Grand Paris Express project aims to better connect the French capital and neighbouring residential areas in the Paris region by building a six-line driverless metro system by 2030. The project will require 210 kilometres of tunnels and almost 70 new metro stations. After winning "Lot GC01", Implenia was also awarded the contract for the extension of metro line 15 to the south-east of Paris ("Lot T2C") as part of a consortium.

The existing Bözberg tunnel between Frick and Brugg does not meet the new requirements for the clearance gauge (corner height 4.0 m) and will therefore be replaced by a new 4-metre corridor as part of the overall project.

The bypass “Förbifart” Stockholm is a link between the north and south of the capital of Sweden and intends to relieve the traffic through the city. The 21 km long bypass motorway, of which approximately 17 km are underground in a depth of up to 70 m, is divided into six lots. With the 3.6 km long Johannelund tunnel (Lot FSE 403), Implenia won the contract for one of the first lots.

In order to enhance North Nuremberg’s accessibility to the local public transportation system, the existing subway network will be expanded with the construction of the new U3 line. One section of this new line, south-west section 2.1, extends from “Gustav-Adolf-Straße” station to the border of section 2.2 in direction to “Kleinreuth” station.

The planned Semmering Base Tunnel (SBT) is currently one of the most important large-scale infrastructure projects in the heart of Europe, and forms part of the new Austrian southern railway, a central axis on the trans-European route from the Baltic to the Adriatic. With an overall length of 27.3 km, the SBT links Lower Austria with Steiermark. Österreichische Bundesbahn [Austrian Railways] has appointed Implenia as part of a consortium with Swietelsky for the construction of central Lot 2.1, a section about 13 km in length.
