Remove storage hall Hamburg

Hamburg, Germany Demolition

Remove storage hall Hamburg

A major German copper manufacturer wanted to demolish its largest warehouse. Despite the immense roof span of 94 meters, DDM managed to remove it without any problems.

The circular hall had a diameter of 94 meters and was almost 30 meters high. Because of the enormous roof span, which was made entirely of concrete, prestressed concrete was used during construction. A concrete prestressed ring was placed on the outside of the concrete uprights. A specific construction that required a very specific approach from DDM.

All components, indoor hoisting facilities and conveyor belts within the building were removed, followed by the steel wall cladding and roof panels. The entire building was stripped until only the main supporting structure remained.

The concrete roof trusses were laid on the outer prestressed concrete ring and on the concrete top ring during construction. The trusses could only be removed if the top ring was supported by an auxiliary structure. This construction was placed against the ring with a jack system. Once this had taken over the weight, the trusses could be removed. They were cut loose and lifted off using the long arm and bolt cutters of the demolition crane.

The concrete top ring was removed with two hydraulic cranes. To release the tension from the prestressed outer ring, it was weakened in specific places by breaking the concrete. After this action, the rest of the hall could be demolished in a conventional manner. The demolition cranes were used to crush the concrete structure and separate the reinforcing steel.
