The pre-tensioning of the concrete container with a height of approx. 60 m and a diameter of approx. 46 m was carried out using horizontal tendons BBV, L7, BBV L15 and BBV L19 in the silo wall, which each run over half the tank circumference and alternately vertically on a total of 4 Pilaster strips were anchored. The silo was built using a sliding construction method. […]

In autumn 2014 NCC was commissioned by Statens Vegvesen to rebuild an approx. 6 km long section of the E18 between Knapstad and Retvet, approx. 50 km southeast of Oslo. The project contains 3 prestressed concrete bridges that were prestressed with the internal strand tensioning method of BBV Systems: the approx. 62 m long Skaug Bru with BBV L19 tendons the approx. 290 m […]

The bridge connects Anambra State and Delta State. The superstructure is pre-tensioned using BBV L15 tendons, with a total of more than 2,000 t of prestressing steel being installed. Material and equipment delivery Supervision approx. 2,000 t prestressing steel

The Casimcea wind farm is located on the Romanian Black Sea coast, approx. 250 km east of Bucharest. From 2011 to 2013 a total of 88 wind turbines with a total output of 230 MW were built in 3 construction phases. These systems are supposed to feed 640 GWh of electricity into the Romanian grid per year and thereby reduce Co2 emissions by approx. 600,000 tons per year. The […]

The location of the construction site at over 2,100 meters above sea level only allowed construction work in a few months per year. After the tower foundations were completed in summer 2019, the towers were erected in summer 2020. Immediately afterwards, BBV Systems delivered the prefabricated tendons for the 5 towers over the St. Gotthard Pass to the construction site and […]

In 2020, in the north of Temuco, near Cajon, the approx. 300 m long Cautin River Bridge was built, which crosses both the Cautin River and the Temuco-Santiago railway line. The 7-span prestressed concrete bridge was built by the ConPax company with single-span girders. The BBV L12 system according to ETA-05/0202 was used for prestressing steel work; the work was carried […]

The structure was erected in 17 construction phases, its total span is 630 m. Tendons with a subsequent BBV L22 bond were installed in the single-web T-beam. These were manufactured entirely according to the needs of the client. The tendons, each spanning two construction phases, were prefabricated in the manufacturing plant and delivered wound on drums. For all other […]

The wind farm consists of 2 Enercon E-115 wind turbines with a rotor diameter of 115 m, a hub height of 90 m and a total output of 6.4 MW. The towers consist of precast concrete elements that were placed on top of one another on the construction site using a mobile crawler crane. The external tendons for the tower prestressing were manufactured at BBV in Bobenheim-Roxheim […]

The largest and most powerful system is the Enercon E-141. With a nominal output of 4.2 megawatts, it generates over 10 million kilowatt hours per year, supplies 3,000 average households and saves over 7,000 t of CO2 emissions. BBV Systems was responsible for the prestressing steel work on this and the other wind power towers in the Mainz-Hechtsheim wind farm. The tendons […]

The construction project is located in the Leeden municipality of Tecklenburg, in the Münster administrative district. In the first construction phase, the partial structure in the direction of Bremen was rebuilt. The structure was constructed in 11 construction phases using the incremental launching method. The regular cycle is 24 m, the total length approx 252 m. Tendons […]
