Sustainable　building-demolition-waste　management　has　become　an　important　practice.　Normally,　three　different　methods　of　disposing　of　demolition　waste　should　be　considered:　landfill,　reuse,　and　recycling.　The　use　of　traditional　documentation　techniques　for　assessing　the　environmental　impact　of　different　disposal　methods　during　the　end-of-life　(EOL)　stage　results　in　hundreds　of　detailed　instruction　sheets　that　need　to　be　stored.　In　this　study,　a　life-cycle　assessment　(LCA)　framework　is　proposed　for　the　evaluation　and　comparison　of　the　environmental　impacts　of　the　three　disposal　strategies　mentioned　above　in　terms　of　factors　such　as　the　extraction　of　resources,　loss　of　biodiversity,　and　effect　on　human　health　by　using　the　information　obtained　with　typical　building　information　modeling　(BIM).　In　the　LCA　framework,　four　environmental-impact-allocation　types　(namely,　no,　equal,　mass,　and　economic　allocations)　are　used　to　calculate　the　final　impacts　of　the　products　to　be　shared　by　more　than　one　product　system.　The　results　reveal　that　a　particular　disposal　strategy　should　be　investigated　by　considering　an　entire　building　to　assess　the　effective　reuse/recycling　potential.　In　addition,　a　BIM-based　plug-in　(BIM-EF)　is　developed　for　the　automatic　appraisal　of　the　environmental　impact　of　buildings　at　the　EOL　stage　by　using　Revit　Add-in　Manager.　Two　data　libraries　(the　engineering　quantity　data　library　and　environmental　impact　factor　library)　are　created,　and　a　coding　system　is　established　to　connect　the　information　stored　in　the　BIM　model　and　the　two　data　libraries.　Finally,　the　results　of　a　case　study　are　presented　to　illustrate　the　potential　applications　of　the　proposed　method.
