  • Ligerz-Twann double track extension a complex rail infrastructure project

    Ligerz-Twann double track extension a complex rail infrastructure project

    The contract includes the 2.1 km long double-track tunnel – about 1,850 m of which will be excavated and about 250 m of which will be built using cut-and-cover methods – including concrete lining and railway technology. In addition, four escape tunnels, a 114 m long viaduct for the N5 motorway exit and various additional structures are being built. The excavated material will be transported by ship and the existing railway line will be dismantled and redesigned.

    The aim of the project is to eliminate the last railway bottleneck on the Jura river line between Lausanne and Biel. Due to the prevailing narrow space conditions between the lake and the slope, where the N5 national road and the cantonal road also run, a new double-track tunnel will be built.

    A particular challenge is the project’s location in protected areas: The region is listed in the Federal Inventory of Landscapes and Natural Monuments (BLN). The villages of La Neuveville, Chavannes, Ligerz and Twann are part of the Federal Inventory of Swiss Sites of National Importance (ISOS).

    Christian Späth, Head Division Civil Engineering at Implenia: “We are looking forward to executing this large and complex railway infrastructure project together with our ARGE partners and to once again demonstrating our many years of experience and expertise in this field. We wish the entire project team an accident-free construction period.”

    The core of the work is the 7.3 km long drive with a diameter of 12.3 m through a tunnel boring machine (TBM) with segmental lining. This connects to a 160 m long, conventionally excavated take-off run. Further work of the order is the 430 m long, conventional drive through the fault zone north, from the 4 km long north access tunnel currently under construction

    is broken out. The TBM will later be pulled through this section of the fault zone and its cutter head will be completely overhauled. The TBM will then tackle further tunneling to the lot boundary. The ARGE will also create a highly complex excavation of two underground ventilation centers as well as an underground concrete plant and production halls for tubbings and service ducts in former military caverns.

    FEDRO justifies the award as follows: «The ARGE 'secondo tubo' has submitted a very good offer in terms of quality and price, and therefore the most advantageous offer overall. The tender from the successful tenderer is consistently convincing with award criteria that are judged to be good to very good. The bidder has submitted the most advantageous offer and can also qualitatively stand out from the other bidders on the basis of the submitted offer documents. The key people assigned to work on the construction site are rated as very good.»

    André Wyss, CEO of Implenia, on the contract he had won: “The second tube of the Gotthard road tunnel is making a significant contribution to improving the north-south road connection in Switzerland. We are very pleased that this large and complex infrastructure project, which fits in well with Implenia's strategy

    fits, are allowed to plan and build. We can optimally use our many years of experience and proven expertise in tunnel construction and in other disciplines of civil engineering.»

    In addition to the tunnel construction, Implenia will also be involved in special civil engineering and civil engineering units in Central Switzerland.

  • New innovative business park in Altstetten

    New innovative business park in Altstetten

    Glass, metal and exposed concrete – the new commercial property Manufakt 8048 was created as a minimalist blank and at the same time a prototype for sustainable service and production facilities.

    With the concept and the brand "Manufakt", the real estate developer Steiner AG wants to offer more utility with less resource consumption. Manufactory 8048 has various “shared spaces” – common areas such as reception areas, meeting rooms or meeting areas. This reduces the direct room costs and the operating costs for additional areas. This should also attract young companies.

    The office building manages without load-bearing walls and thus offers a flexible spatial grid. In addition, Steiner AG has designed "room boxes" for individual workstations, which can be put together in modules if required.
    The new tenants in Altstetten are currently in the process of individually designing their floor plans as part of the tenant fit-out and converting the up to 4.5 m high rooms into production and office areas, laboratories and showrooms.

    The design of the building in Altstetten was developed and planned by Theo Hotz Partner Architekten. Although Theo Hotz (1928-2018) was considered one of the best-known high-tech architects in Switzerland during his lifetime, the Manufactory 8048 was designed as a "low-tech" building: the building technology and the standard of construction are minimal, the structural details are simple. The clear design language of the building results from a simple cubic outline with six floors. These can be recognized from the outside by continuous glazed ribbon windows and horizontal aluminum parapets. In the building, industrial
    tial materials such as steel, exposed concrete and seamless industrial floors together with exposed installations.

    In the center of the building is an airy atrium, which serves as an open inner courtyard for access and becomes an attraction, meeting point and relaxation area. The liveliness in the inner courtyard is supported by greenery, which is intended to contribute to a positive climate. Lifts and cantilevered arcades lead from the inner courtyard to the floors.

    In Wädenswil and Winterthur, two more industrial parks will be built in the coming years based on the Manufakt concept. An important element is the networking of the various tenants across the locations.
