Abstract: V zaključnem delu obravnavamo uporabo naprednih digitalnih tehnologij v gradbeni praksi, s poudarkom na 3D laserskem skeniranju izvedenega objekta in analizi odstopanj med izvedenim in projektiranim stanjem. V ta namen smo s pomočjo 3D laserskega skeniranja pridobili natančen oblak točk novozgrajenega objekta (klubski prostori NK Miklavž) ter ga primerjali s 3D BIM modelom, izdelanim na osnovi prvotne projektne dokumentacije. Za analizo in vizualizacijo odstopanj smo uporabili programski orodji BIMmTool (v okolju Archicad) in CloudCompare. Cilj naloge je bil prikazati učinkovitost tovrstnih orodij pri natančnem tehničnem nadzoru izvedbe ter osvetliti možnosti, ki jih digitalni pristopi nudijo za izboljšanje kakovosti gradbenih projektov.

Abstract: Magistrska naloga je osredotočena na analizo interoperabilnosti med BIM orodji in orodji za MKE analize na primeru večstanovanjskega objekta. Prikazan je postopek izdelave BIM modelov v programih Allplan in Revit ter ocenjene prednosti in slabosti posameznega orodja. V okviru naloge so bile obravnavane tri izmenjave podatkov med programi: Allplan – SCIA Engineer s pomočjo orodja SCIA AutoConverter, Revit – SOFiSTiK ter Revit – SCIA Engineer s pomočjo vtičnikov za Revit. Vsaka izmed izmenjav je bila analizirana, hkrati pa so bile podane ocene njihove uspešnosti. V zaključnem delu naloge so bile izvedene statične analize v programih SCIA Engineer in SOFiSTiK, pri čemer sta bili orodji tudi medsebojno primerjani. Predstavljena je bila primerjalna tabela z rezultati statičnih analiz za vsak primer izmenjave, pa tudi za modela, ustvarjena neposredno v programih za MKE analizo brez prenosa podatkov. Procentualna odstopanja v rezultatih so bila minimalna. Rezultati so pokazali, da je interoperabilnost med orodji na splošno uspešna, vendar so za zagotovitev popolne usklajenosti podatkov potrebne dodatne prilagoditve.

Abstract: The intelligent management of built cultural heritage, including heritage buildings, requires common semantics in the form of standardized ontologies to achieve semantic interoperability. Foundational ontologies should be reused when building new ontologies, as they provide high-level terms; however, candidate foundational ontologies should be evaluated for quality and pitfalls. Simple metrics (e.g., number of concepts) are easy to obtain with existing tools. Complex metrics such as quality of ontology structure, functional adequacy, transferability, reliability, compatibility, maintainability, and operability, are defined in recent ontology evaluation frameworks; however, these do not evaluate interoperability features. The paper proposes an improved framework for an automated ontology evaluation based on the OQuaRE framework. Our approach improved some of the metrics of the OQuaRE framework and introduced three metrics for assessing the interoperability of the ontology in question (Externes, Composability, and Aggregability). In the experimental section, the framework is validated in an evaluation of cultural heritage information ontology (CIDOC CRM—ISO 12217:2014) with the use of new software for ontology evaluation. The detailed results reveal that the ontology is minimally acceptable and that the improved evaluation framework efficiently integrated interoperability metrics. Recommendations for the improvement of the cultural heritage information ontology are described in the Discussion and Conclusions section.

Abstract: Purpose – Ready-mix concrete delivery problem (RMCDP), a specific version of the vehicle routing problem (VRP), is a relevant supply-chain engineering task for construction management with various formulations and solving methods. This problem can range from a simple scenario involving one source, one material and one destination to a more challenging and complex case involving multiple sources, multiple materials and multiple destinations. This paper presents an Internet of Things (IoT)-supported active building information modeling (BIM) system for optimized multi-project ready-mix concrete (RMC) delivery. Design/methodology/approach – The presented system is BIM-based, IoT supported, dynamic and automatic input/output exchange to provide an optimal delivery program for multi-project ready-mix-concrete problem. The input parameters are extracted as real-time map-supported IoT data and transferred to the system via an application programming interface (API) into a mixed-integer linear programming (MILP) optimization model developed to perform the optimization. The obtained optimization results are further integrated into BIM by conventional project management tools. To demonstrate the features of the suggested system, an RMCDP example was applied to solve that included four building sites, seven eligible concrete plants and three necessary RMC mixtures. Findings – The system provides the optimum delivery schedule for multiple RMCs to multiple construction sites, as well as the optimum RMC quantities to be delivered, the quantities from each concrete plant that must be supplied, the best delivery routes, the optimum execution times for each construction site, and the total minimal costs, while also assuring the dynamic transfer of the optimized results back into the portfolio of multiple BIM projects. The system can generate as many solutions as needed by updating the real-time input parameters in terms of change of the routes, unit prices and availability of concrete plants. Originality/value – The suggested system allows dynamic adjustments during the optimization process, andis adaptable to changes in input data also considering the real-time input data. The system is based on spreadsheets, which are widely used and common tool that most stakeholders already utilize daily, while also providing the possibility to apply a more specialized tool. Based on this, the RMCDP can be solved using both conventional and advanced optimization software, enabling the system to handle even large-scale tasks as necessary.

Abstract: V zaključnem delu smo se osredotočili na uporabo naprednih tehnologij v gradbeništvu in pripadajočih strokah ter pregledali ugotovitve, analize in zaključke, pridobljene med raziskavo. Skozi celotno nalogo podrobno obravnavamo različne vidike uporabe naprednih tehnologij, kot so virtualna (VR), obogatena (AR) in mešana resničnost (MR), ter pripadajočih naprav in njihov potencial za optimizacijo procesov v gradbeništvu. Najprej bomo predstavili teoretični okvir in pregledali relevantno literaturo o uporabi naprednih tehnologij v gradbeništvu, potem pa se bomo posvetili še praktičnemu primeru, ki je omejen na eno stanovanje v večstanovanjskem objektu in pri katerem bomo opisali uporabo VR, AR in MR. Nato bomo s pomočjo analize ankete predstavili uporabniško izkušnjo posamezne tehnologije in pripadajoče naprave, kjer smo ugotovili, da se je v analiziranem vzorcu predstavnikov gradbene panoge kot najbolj uporabna izkazala mešana resničnost in naprava Trimble XR10 s Hololens 2.
