![]() ![]() ![]() This study develops the first Circular Building Lifecycle Framework, namely Inception to Circulation, by (i) clarifying the R principles, (ii) differentiating lifecycle approaches, (iii) unifying fragmented building lifecycle stages, and (iv) integrating R principles with building lifecycle stages. However, existing lifecycle approaches not only omit the early stages to observe such principles but fail to reflect the evolving nature of the building lifecycle. However, every identified driver should be considered during the deconstructability assessment of a building.Ĭircular Economy requires a closed-loop material cycle and seeks ways to apply circular principles. A total of 44 drivers influencing deconstructability were established and ranked from which design and building technology, cost including expense and revenues from the resale, supply and demand of the recovered component and material, the schedule for the deconstruction were identified as most influential. This framework – built around technical, economic, legal, operational, schedule and social construct – describes the condition under which deconstruction is likely to work and drivers influencing deconstructability. This research carried out a systematic literature review of 35 academic and 3 non-academic pieces of literature to develop a construct-based deconstructability framework. However, the feasibility of deconstruction has placed a massive limitation on the implementation of deconstruction. It can turn the negative impacts of demolition, including diverting valuable resources from the congested landfill into beneficial use through reuse and recycling. Value for authors: The authors aim to provide a methodology for improvement building deconstructability.ĭeconstruction is an innovative and sustainable option for building end-of-life. 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. Implications: The results can be translated into an assessment method to be validated in real world. Limitations: The proposed research is limited to assess the building deconstructability processes. Seventy-three unique interactions were found, all but nine were constructive interactions. Therefore, this research analyzes the Lean-BIM interaction in deconstruction processes.įindings: 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. However, the synergies between them in deconstruction context is not yet fully explored. Research Method: Both initiatives, though they are applied independently, proved to have a profound impact on the construction industry. Purpose: This research investigates the interactions between Building Information Modelling and Lean Principles towards improving the deconstruction processes. 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. Therefore, buildings undergo renovation or reconstruction, which requires the total or partial demolition of the buildings in order to meet these new requirements. Question: The static nature of existing building assets is not serving the continuous change in the functional requirements of their end-users. ![]()
