The two superstructures of the 450 m long and 62 m high Lahntal Bridge each consist of two haunched, longitudinally prestressed hollow girders that were erected in cantilevered cantilevering. 170 t external pre-tensioning 500 t internal pre-tensioning Installation, stressing and injection Procedure: BBV L15 BBV L15E

The bridge spans the Tresfjord between the towns of Vestnes and Vikebukt. The superstructure of the main bridge with a maximum span of 160 meters was built from two pillars using the cantilever method. The two approach bridges are built on a feed scaffold with a standard span of 60 meters. Longitudinal prestress

The remaining part of the building will be driven under by the new DB Nordkopf tunnel. In order to be able to produce the tunnel section, the building had to be underpinned on around 50% of its area. The support was carried out with the help of a prestressed 1.35 m thick, point-supported reinforced concrete slab. Client: DB Netz AG Executing construction company: Ed. […]

The construction of the Unstruttal bridge was built according to the latest state of engineering. The roadway runs on jointless and bearingless reinforced concrete girders lying one behind the other. At their ends, the temperature deformation is recorded by special devices. In a former open-cast mine, the soil had to be dynamically compacted. The roadway girders were built […]

In the course of the six-lane expansion of the A3 Frankfurt - Nuremberg motorway, a new building was necessary due to considerable damage to the Main Bridge near Würzburg-Randersacker. Construction work on the new bridge began in July 2007. First of all, the superstructure for the carriageway towards Frankfurt was built next to the old bridge, and this was completed at the […]

The Marieholm Tunnel is a road tunnel with a cross-section of approx. 30 x 10 m and 3 lanes each. The middle, approx. 300 m long section of the tunnel was constructed as a sinking tunnel. In a dry dock, 3 tunnel elements approx. 100 m long were created, which were lowered into a canal excavated in the river bed after floating out. The elements were pre-tensioned in the dry […]

The design for the 5-storey building with approx. 18,000 m² of office space comes from the architects Diener & Diener, and the law firm 'Arendt & Medernach' has been using most of this space since its completion. BBV Systems manufactured over 4,000 monostrand tendons (type BBV L1P) for the prestressing of the 5 ceilings. Due to the limited space on the construction site, […]

The bridge has a total length of 1,540 m. It is part of the A1 motorway from Toruń to Stryków. As a subcontractor to the construction company STRABAG, BBV Systems was responsible for the post-tensioning work, which included the installation of internal and external tendons. The superstructures were built using advancing scaffolding. The use of advancing equipment made it […]
