Circular economy in demolition - dismantling for reconstruction

Deconstruction of assembled steelwork is generally a straightforward task. However, facility owners and contractors are facing many challenges when trying to streamline the process into the successful reuse project when the recovered components are assembled again in a different place.

One of the barriers for successful reuse is lack of reliable and accurate information about the components, their material quality, coating or modifications made during their previous life.

There are also challenges in understanding the whole deconstruction process and what are the changes between the ordinary demolition and deconstruction processes.

VTT Technical Research Centre of Finland and Purkupiha as leading demolition contractor in Finland, are partners in EU Horizon 2020 project called Iceberg, in which they demonstrated deconstruction and reuse of used building components and steel frames on demolition sites.

The aim was to indicate major challenges in deconstruction process and find solutions or create suggestions into value chain members that are involved. They also demonstrated pre-deconstruction audit including 3D scanning of a steel hall that was sold for reuse.

Contractors or facility owners can nowadays offer deconstructed building components for sale on various trading portals in Finland, but the information about their material and dimensions is typically produced after deconstruction.

With the demonstrated BIM model and RFID traceability system, the information can be ready before deconstruction, allowing more efficient reuse and better decision-making in deconstruction planning phase.
