purkukokeella

Pur kukokeella refers to a controlled test procedure used during planning for building demolition. The term is of Finnish origin, combining purku meaning demolition and kokeella meaning "on trial" or "for testing." The concept is applied to verify structural response, equipment performance, and site logistics on a representative part of a structure or a full-scale mock-up before committing to actual demolition work.

Implementation typically involves selecting a test object, installing instrumentation, applying loads or staged demolition actions, recording data on loads, vibrations, dust, and debris control, and analyzing results to refine methods, scheduling, and safety measures. The aim is to identify potential issues, optimize procedures, and strengthen safety planning before executing the main demolition operation.

Pur kukokeella is not a formal standard but is used within broader demolition planning and risk assessment processes. It complements compliance with national regulations and industry guidelines on worker safety, dust suppression, noise control, and waste management. The approach is most common in complex or high-risk projects where precise sequencing and controlled conditions can reduce uncertainties.

Limitations include that small-scale tests may not capture all dynamic effects of full-scale demolitions, and there are costs, scheduling constraints, and potential safety risks associated with conducting live tests. In Finnish industry literature, purkukokeella appears in project documentation and training materials; outside Finnish-speaking contexts the term is uncommon.
