A BIM-based framework for quantitative assessment of steel structure deconstructability

Recently, attention is being focused on Design for Deconstruction (DM) as one of the most effective structure end-of-life design scenarios. Although several research efforts have dealt with the DfD and reversible buildings design theories for the past few years, the lack of technological support for developing tools to improve DM to be BIM compliant has been clearly noticed. This research presents a Deconstructability Assessment Scoring (DAS) methodology for quantitative assessment of Steel Structures deconstructability. The proposed methodology takes into consideration a number of steel parameters and their deconstructability. Seven innovative solutions contributing to steel connections deconstructability are considered in the proposed research. Furthermore, steel elements reusable fire-proofing systems are introduced to provide the required fire resistance and deconstructability. The detailed analyses for the selected parameters are adopted and implemented to form the Steel Structure Deconstructability Assessment Scoring (SS-DAS). The proposed methodology is implemented in Autodesk Revit using Dynamo. The proposed innovative solutions are modeled as families to automate the scoring process.
