Abstract
This thesis examines how digital twins can be implemented in the operations and maintenance (O&M) phase of a building’s lifecycle. Motivated by the AEC sector’s slow technology adoption and known challenges in realizing BIM’s benefits in O&M—including industry fragmentation, limited BIM–IoT integration, and legacy data issues—the study combines a systematic literature review with interviews with industry practitioners. Its aims are to map the current state of digitalization in O&M, clarify key concepts and components of a building-focused digital twin, and highlight the value such implementations can offer stakeholders. The work situates digital twins within Industry 4.0, incorporates perspectives from bodies such as buildingSMART and the CDBB, discusses maturity levels, and contrasts BIM and digital twins. Based on the review and interviews, it addresses recurring themes including remote monitoring and 3D visualization, IoT integration, and the use of intelligent algorithms for predictive performance. It outlines a proposed component model for an O&M digital twin and discusses end-user value, limitations, and recommendations. Specific quantitative findings are not included in this excerpt.
Dette speciale undersøger, hvordan digitale tvillinger kan implementeres i drifts- og vedligeholdelsesfasen (O&M) af bygningers livscyklus. Med afsæt i den langsomme teknologiadoption i AEC-sektoren og de dokumenterede udfordringer ved at udnytte BIM i O&M—bl.a. fragmentering, manglende integration mellem BIM og IoT samt legacy-formater—kombinerer studiet en systematisk litteraturgennemgang med interviews med brancheaktører. Formålet er at kortlægge den aktuelle digitaliseringsstatus i O&M, tydeliggøre centrale begreber og komponenter i en digital tvilling til bygninger og belyse den værdi, som implementeringen kan skabe for interessenter. Specialet sætter DT i kontekst af Industry 4.0, inddrager perspektiver fra bl.a. buildingSMART og CDBB, diskuterer modenhedsniveauer og sammenligner BIM og DT. På baggrund af gennemgangen og interviewene adresseres gennemgående temaer som fjernovervågning og 3D-visualisering, IoT-integration samt anvendelse af intelligente algoritmer til prædiktiv drift. Der skitseres et forslag til komponenter i en DT-løsning for O&M, og værdiskabelse for slutbrugere diskuteres sammen med begrænsninger og anbefalinger. Konkrete effektestimater ligger uden for dette uddrag.
