Implenia has received a contract worth over €200m ($226.9m) for the construction of a section of the Nordmainische S-Bahn below central Frankfurt, Germany.
The contract was issued by DB InfraGO, part of German state-owned railway company Deutsche Bahn.
The new underground section will extend from Konstablerwache in the city centre to Fechenheim, passing through the new ‘Frankfurt (Main) Ost (tief)’ S-Bahn station.
Implenia’s responsibilities include building the initial construction pit, known as the ‘Trog’, and the pit for the underground station, as well as several auxiliary construction pits and associated civil engineering structures.
Additionally, Implenia will be drilling two tunnel tubes, each around 1.2km in length, using tunnel boring machines (TBMs) and implementing water management measures.
The complexity of the project is heightened by its location in a populated area of the city, necessitating a range of special foundation services to meet the demands of modern and sustainable construction.

Implenia Civil Engineering head Edwin Scherer said: “Maintaining and developing a functioning transport infrastructure is central to the sustainable development of our cities. I’m very pleased that Implenia, with its many years of experience and comprehensive expertise, can contribute to the improvement of public transport in the densely populated Rhine-Main region.”
The Nordmainische S-Bahn project is a strategic investment in the transport infrastructure of the future, aiming to enhance local transport connections.
The project is seen as pivotal for expanding rail capacity in the Frankfurt (Main) hub and is expected to deliver improved reliability and comfort for commuters and travellers while also contributing to carbon reduction targets, highlighted Implenia.
Last month, Deutsche Bahn commissioned a joint venture of Implenia and HOCHTIEF for ‘733 Tunnel Ostbahnhof’, a component of the Munich S-Bahn expansion project.
