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.

Other milestones
Research project: MAMA - Machine-based, automated, unmanned demolition process
Development: RDB 100i
Together with the TU Dresden and IBL-hydronic, we are working on the MAMA process (machine-based, automated, unmanned, demolition process) for the RDB 100i.
MB Spezialabbruch - Milestones: Wire saw
Wire Saw
A wire saw is often used to process components with large cutting depths and to cut tubular structures to size.
MB Spezialabbruch - Milestones: Wall saw
Wall Saw
Saw blades with a diameter of up to 1,600 millimeters are used for the wall saw, which allows for cutting depths of up to 730 millimeters.
MB Spezialabbruch - Milestones: Drop anchor
Drop Anchor
The heavy-duty fastening device (drop anchor) is used to fasten loads to building structures where the wall panel has to be anchored.
