The integration of blockchain and digital twins (DT) for better building-lifecycle data management has recently received much attention from researchers in the field. In this respect, adoption enabling technologies such as artificial intelligence (AI) machine learning (ML), Internet Things (IoT), cloud edge computing, Big Data analytics, etc., also been investigated an abundance studies. present review inspects recent studies to shed light on foremost among those their scope, challenges,...

The emerging availability of numerous model-based design and analysis tools promises high interoperability in terms data exchange, thus shorter planning cycles higher quality. However, seamless transfer digital models across domains without significant inconsistencies is still a major challenge the practice. This paper aims to identify procedural problems between architectural structural propose improvement. study reviewed current exchange practices, concluded that based on industry...

The heterogeneity of the architecture, engineering and construction (AEC) industry reflects on digital building models, which differ across domains planning phases. Data exchange between architectural design structural analysis models poses a particular challenge because dramatically different representations elements. Existing software tools standards have not been able to deal with these differences. research inter-domain information modelling (BIM) frameworks does consider geometry...

Building information modelling promises model-based collaboration between stakeholders in the project design stage. However, data exchange physical and analytical building models used for architectural structural analysis respectively rarely takes place due to numerous differences element representation, especially representation of geometry. This paper presents realization a novel framework models, based on open interpretations central storage. The is achieved with new system architecture,...

Proposal for a Discipline-Specific Open Exchange Framework Goran Sibenik and Iva Kovacic Pages 570-577 (2018 Proceedings of the 35th ISARC, Berlin, Germany, ISBN 978-3-00-060855-1) Abstract: Several data exchange standards support open building data. Industry Foundation Classes (IFC) standard is most widely implemented within software solutions used in practice. This developed by buildingSMART International describes schema defined with EXPRESS modelling language also including validation...

Various standards concerning the implementation of building information modelling (BIM) are available. This paper investigates correlation between adoption international and BIM by practitioners across Europe. At core research is a questionnaire answered industry experts from 21 countries. The results show that does not correlate with standards. combined literature indicate need for better strategies diffusion findings pinpoint potential improvement more effective use

Numerous stakeholders contribute to building projects during the design phase, prevailingly dealing with digital objects. The phase is characterised by project-specific heterogeneous workflows that are not standardised. Available software tools still do sufficiently support management of these across industry. However, single activities within similar and constitute patterns could allow for modularisation eventual standardisation. An analysis protocols found on a document-exchange platform...

The presented research project DiCYCLE aims at identifying, analyzing and mapping current End-of-Life processes in Architecture, Engineering Construction, as well optimizing these for digitalization, using Building Information Modeling, blockchain smart contracts. goal is to create new business models enable sustainable digital design, construction deconstruction workflows that facilitate the reuse recycling of building materials components along life cycle.

Blockchain-supported design tool on building element scale Goran Sibenik, Marijana Sreckovic, Thomas Preindl, Martin Kjäer, and Wolfgang Kastner Pages 566-573 (2022 Proceedings of the 39th ISARC, Bogotá, Colombia, ISBN 978-952-69524-2-0, ISSN 2413-5844) Abstract: Sharing data or models still represents a problem within practices in architecture, engineering construction industry. Additionally, digitalization, automation traceability processes face numerous workflows changing stakeholder...

Numerous stakeholders contribute to building pro-jects, which mainly deal with digital assets during the design phase. Design workflows are project specific and not standardized, therefore tools supporting improving these widely present. However, activities within similar constitute patterns that allow for workflow standardi-zation. We analyze an existing document exchange platform in order identify those pat-terns a way unveils their automation poten-tial. The proposed modular can serve as...

Automated model preprocessing for structural analysis Goran Sibenik, Iva Kovacic and Valentinas Petrinas Pages 153-160 (2021 Proceedings of the 38th ISARC, Dubai, UAE, ISBN 978-952-69524-1-3, ISSN 2413-5844) Abstract: Numerous modelling workflows reflect heterogeneity vague standardization in construction industry; hence their automation is not straightforward. Procedures like redefining geometry from scratch or assigning loads one-by-one, are mostly performed manually, time-consuming...

The increasing complexity of communication and collaboration processes due to the use build-ing data models object-based change management, create need for efficient ways transparency traceability within planning processes. growing presence BIM (Building Information Modelling) digi-talises AEC industry produces numerous assets in digital form, but their added value is not completely exploited. Blockchain (BC) Smart Contracts (SC) might deliver improvement col-laboration design phase. Based...
