Amager Bakke

Amager Bakke, also known as "Amager Berg", is one of the largest environmental developments in Europe and a central component of the development concept for the Amager peninsula off the east coast of Copenhagen. The waste incineration plant disposes of the waste of the entire urban population of Copenhagen and at the same time generates environmentally friendly electricity and district heating for up to 150,000 households. The former industrial site has been transformed into a modern urban recreational and residential area. The 60-metre wide, 200-metre long and up to 90-metre high building is open to the public: ski slopes, a landscape park with wooded areas, hiking trails, climbing walls and a viewing platform have been created on the roof.

ZÜBLIN Stahlbau was commissioned with the implementation of the building's steel construction and the precast concrete construction following successful prequalification in March 2014. Our services included the work planning, including connection statics, as well as the manufacture and assembly of:

• 6.500 tons of building steel construction
• 23.000 m² reinforced concrete hollow core elements including in-situ concrete work
• 2.000 m² reinforced concrete wall elements
• 14.000 m² sandwich walls with fire protection classification

We also realized the roof drainage as well as the delivery and installation of the chimney. The steel structures were predominantly manufactured in the EXC 3 and 4 design classes and made from material grades S355 and S460.
The integration of complex industrial technology into an unusual building structure with a mountain-like appearance required innovative solutions. The architects and Copenhagen planners from MOE A/S chose a three-dimensional steel structure that combines different types of construction: Hall constructions in the delivery area and in the area of the waste bunker, tree-like supporting structures in the process area and storey constructions with prestressed concrete ceilings in the administration area. The project relied on BIM-supported planning: a 3D model was already available during the tendering process, which served as the basis for engineering, assembly planning and schedule coordination.

The demanding engineering tasks were carried out by the ZÜBLIN steel construction team in Hosena in close cooperation with external engineering service providers. The complex welded constructions were manufactured in the workshops in Hosena. Assembly was carried out in cooperation with partner companies, while our own teams assembled the steel and façade elements. In the areas of reinforced concrete and chimney construction, we worked in partnership with Ed. Züblin AG Ingenieurbau Nord and the former Züblin Chimney & Refractory GmbH right from the tendering phase.

The construction consists of stabilizing components and trusses made of welded box cross-sections. The complex execution of the sheet metal structures, including welding work, clearly distinguishes the project from the usual sectional steel construction and makes Amager Bakke a sophisticated reference for modern steel and concrete construction in all phases of work.
