Abstract:

Question: The static nature of existing building assets is not serving the continuous change in the functional requirements of their end-users. Therefore, buildings undergo renovation or reconstruction, which requires the total or partial demolition of the buildings in order to meet these new requirements. This results in more virgin materials pumped into the construction industry to substitute the wasted ones, leading to an increase in the construction and demolition wastes.

Purpose: This research investigates the interactions between Building Information Modelling and Lean Principles towards improving the deconstruction processes.

Research Method: Both initiatives, though they are applied independently, proved to have a profound impact on the construction industry. However, the synergies between them in deconstruction context is not yet fully explored. Therefore, this research analyzes the Lean-BIM interaction in deconstruction processes.

Findings: The proposed framework relies on the existing Lean-BIM interaction matrix to evaluate the compliance of each BIM Functionality with each perspective Lean Principle based on evidence from literature and current practice in demolition projects. Seventy three unique interactions were found, all but nine were constructive interactions.

Limitations: The proposed research is limited to assess the building deconstructability processes.

Implications: The results can be translated into an assessment method to be validated in real world. This exploratory research can be a foundation for establishing stable markets for salvaged elements and encouraging a behavior change in the construction industry towards circular economy.

Value for authors: The authors aim to provide a methodology for improvement building deconstructability.

Keywords: Lean deconstruction, Building Information Modelling (BIM), Pull-Planning, Sustainability, Circular Economy.
