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 […]

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 […]

With the BRIMOS® method, the cable forces are determined from the measured dynamic characteristics, taking into account the inherent rigidity of the cable. The present results serve to check the cable forces before opening the car to traffic and as a reference for later follow-up examinations. The measurements were carried out with the BRIMOS® recorder. The external […]

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 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 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 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. […]

Greece's only LNG (liquefied natural gas) terminal is located on the island of Revithoussa, which is located in the Gulf of Pachi approx. 45 km west of Athens. As part of the second expansion phase of the terminal, a third LNG tank was built in 2017/2018 to increase the storage capacity to 225,000m³. The outer concrete tank with a diameter of 81 m and a height of 27 m […]

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 Krammer wind farm is currently the largest community wind farm in the Netherlands. It is located in the province of Zeeland and was built on and around the “Krammersluizen” near Bruinisse, about 20 km from the North Sea. The wind farm consists of 34 Enercon E-115 wind turbines with a rotor diameter of 115 m and a hub height of 120 m. The towers of the wind turbines […]
