Abstract

Nowadays building works, especially of historic buildings with facades out of natural stone, require continuous maintenance, repair and retrofit works. In order to fulfil the needs for a completely digitized natural stone retrofit process, works are to be projected, planned, conducted and cleared with instrumentation of Building Information Modeling (BIM). Due to this need, a novel knowledge-based stone damage identification system focused on natural stone damage on the basis of BIM is developed, which will present implicitly existing knowledge and information from the building survey explicitly and objectively by using semantic data structures. BIM-SIS is an adaptive damage identification system for natural stone, which allows to virtually merge different natural stone damages, recorded by different information systems and with different procedures, into a holistic damage model. This model is used to assess the damages integrative and in detail, supported by knowledge-based methods, and to develop a uniform and cost-stable remediation strategy. Therefore, the BIM-SIS methodology consists of BIMification for information processes, Ontologies for knowledge representation and Multimodels for data interoperability. The so formed continuous interoperable digital construction representation consists of separate but interlinked domain models. This model structure is then extended for remediation execution management and allows to simply incorporate subsequently detected defects during execution. The complete damage profile is the basis for all further retrofit-creation and calculation processes in BIM-SIS which will automatically lead to user customed retrofit variants presented in VR and AR.
