Sequential Collapse
Developed by: MB Spezialabbruch GmbH & Co. KG
Development timeframe: 2019
Sequential collapse of a structure represents a new method for demolishing buildings. The collapse is not initiated by explosives. Thus, the risks of detonation, such as primary scattering or load or partial load failure, are avoided.
Based on the external conditions, a collapse geometry is first determined. This is followed by targeted pre-weakening of the structure via separating cuts, partial demolitions, or similar. By developing a model, the loads at the critical points of the structure are determined. This allows both the safe pre-weakening of the building and the exact determination of the time of collapse.
The collapse itself is triggered by remote-controlled excavators, saws, or by pulling in or pushing in using winches.
