HOCHTIEF is a German construction company based in Essen, North-Rhine Westphalia, Germany. It is the largest construction company in Germany and has been in operation since 1873. HOCHTIEF also operates globally through subsidiary companies such as Turner Construction Company in the United States and CIMIC Group in Australia.
The company employs over 70,000 people and is worth around 4.26 billion euros. 65% of the company is owned by Spanish civil engineering and construction company Actividades de Construcción y Servicios, S.A.
The company’s engineering and construction projects have started with the transplantation of the Abu Simbel rock temples in Egypt. The company has saved the legacies of Ancient Egypt from the destruction caused by the rise of the Nile River, which was caused by the construction of the Aswan High Dam. The company has also done massive reconstruction projects at Zollverein colliery and the Kandinsky-Klee house, which are both protected by UNESCO and considered World Heritage Sites.
Moreover, iHOCHTIEF was behind the construction of massive projects such as the construction of the International Airport in Athens in 2001 and the first nuclear power plant in Germany in 1960. It is also known for the implementation of new technologies in agriculture. HOCHTIEF’s bridge construction experts are now working on several large-scale bridge-building projects in Germany.
They work on the construction of the Rhine Bridge in Duisburg. Moreover, they are building a new bridge to replace the Lennetal Bridge in Hagen on the A45. There are several more ongoing constructions in Baden-Württemberg and Wuppertal.
Nevertheless, there is a theory that bridges can be used for 100 years without maintenance and replacement, it is generally untrue. The current bridge in Leverkusen was built in 1965 and is 52 years old and is in urgent need of replacement. Due to the extensive traffic over it remains in a very poor condition.
The bridge was built by the German engineer Hellmut Homberg and is a cable-stayed bridge. The cable-stayed bridge is a type of bridge, where the weight of the bridge is supported by several nearly straight diagonal cables. Cables create tension, which runs directly to one or more vertical towers. The length of the current bridge is 1 kilometer 61 meters and the main span is 280 meters tall.
The bridge is a part of Autobahn 1, which connects Heiligenhafen in Schwein-Holstein to Saarbrücken. It is one of the oldest motorways in Europe and the longest autobahn in Germany, which is 793 kilometers. Consequently, it is an important motorway, which has ongoing extensive traffic on it. This is why the cities of Leverkusen and Cologne are working on bridge replacement.
HOCHTIEF was picked out of SEH Engineering, Eiffage Métal, Iemants and Max Bögl to complete the A1 Rhine Bridge in Leverkusen. After the original 260 million euros contract was cancelled. The previous contract had to be canceled in spring 2020 as deficiencies in the steel construction had not been remedied by the contractor.
The company is already in charge of the construction of the Rhine Bridge on the A40 in Duisburg in a joint venture with a total cost of around 500 million euros. This will mean that HOCHTIEF will be responsible for the construction of the two most important infrastructure objects in the Rhine Valley in North-Rhine Westphalia.
The length of the bridge will be 1km and the bridge is crucial for the German motorway networks and the development of the region. Moreover, the weight of the bridge will be around 30,00o tons. The construction is developed by 60 experts to be able to sustain the weight of 90,000 vehicles per day.
The company has already started the preparations to start building the bridge and Clients hope that HOCHTIEF will be able to complete the new bridge by 2024. Moreover, there are several bonuses provided to stimulate the early completion of the project. Together with its partners SEH Engineering, Eiffage Métal, Iemants, and Max Bögl, HOCHTIEF will try to complete the project before the deadline.
