For the prestressing steel test, the accompanying engineering office had openings made on the ceiling of the Altstadtring tunnel using high pressure water jets. The structural concrete, the cladding tube and the cement glue inside the cladding tube were removed. For the further use of the tunnel, these opening points had to be closed again properly and the prestressing […]

The B 311 and the B 14 were bundled in Tuttlingen to improve traffic conditions in Tuttlingen and to create an efficient, national road network. In the course of this, the new construction of the Danube bridge as a 2-span bridge in Tuttlingen was necessary. The superstructure consists of a prestressed and haunched T-beam cross-section, the cross-section height in the field […]

The usable area of ​​the floors from the 7th floor is larger than on the levels below. This is achieved by making the ceilings cantilever from the 7th floor. The loads from the rising storeys in the area of ​​the facade are directed to the center of the building on levels 7-12 through inclined mega-columns. The tensile forces generated at the deflection points are absorbed […]

After the Trimmberg tunnel from the west, the bridge crosses the valley itself, the weirs and the existing traffic routes south of the village of Wehretal. The Eschwege junction is also located in the area of ​​the crossing. The planned Spitzenberg tunnel connects to the south-east of the structure. The structure is designed as a 15-span continuous beam. The cross-section […]

As part of the Norwegian National Transport Plan (NTP) 2010-2019, the E134 was rebuilt on the 13.2 km long section Damasen - Saggrenda to improve access to the village of Kongsberg and to better road safety. Starting in 2017, BBV Systems installed approx. 200 t of prestressing steel for the longitudinal prestressing of the Saggrenda Bridge; the prestressing work was […]

The 576.5 m long Scherkondetal Bridge was awarded the German Bridge Construction Prize 2012 in the “Road and Railway Bridges” category because, according to the jury's verdict, it was “an aesthetically convincing, innovative structure and a milestone in modern railway bridge construction”. It is the first semi-integral prestressed concrete bridge for the high-speed traffic […]

In addition to approx. 1,000 m of road construction, the project included a 580 m long steel composite bridge (Imarsund Bridge) and a 300 m long prestressed concrete bridge (Litjsund Bridge). The prestressed concrete bridge is named after the Litjsund it crosses. It consists of 3 fields and has a span of 160 m in the main field. Both pillars were erected in the water. The […]

The four-lane bridge structure is one of Ulm's most important traffic axes in an east-west direction. The peculiarity of the bridge is its type of construction: The bridge is suspended in a prestressed concrete band that is guided over the pylons. The pylon height is approx. 20 m above the road surface, the prestressed concrete belts are each 40 m long. During the […]

The cable-stayed bridge crossing the Sava River with a length of 929 m and a considerable carriageway width of 45 m has been the new landmark of the city of Belgrade since its completion in 2012. The bridge superstructure was built in prestressed concrete in the backspan and sidespan area and in steel construction in the mainspan area. Porr Technobau und Umwelt AG was […]
