Interoperability of infrastructure and transportation information models: A public transport case study
Nenad Čuš Babič, Sara Guerra de Oliveira, Andrej Tibaut, 2022, original scientific article

Abstract: The duplication of semantic data modelled in different disciplines poses interoperability challenges. Information models that benefit from the application of standards that enable data reusability and prevent redundancy and misuse should be compatible, particularly when different systems are used in the same domain-specific area, as in the case of public transportation. Transportation information models, leading and providing reliable and robust public transport services, can nowadays be enriched with information found in building information models devoted to transportation infrastructure. Therefore, in the present paper, a mapping between the standards and technical specifications that support each modelling approach is explored, analysed, and aligned to maximise the best out of the current common practices used. The information from the Industry Foundation Classes IFC specification-based models complements the conceptual and physical transportation models, where Transmodel and NeTEx are well-established, with accurate (as-built) detailed characteristics of the transportation infrastructure (stop places, quays, entrances, access spaces and equipment as ramps, staircases, and escalators). The extraction of topological information stored in IFC models allows for navigation-network extraction, information about spaces, and passages between spaces. A specific public transport case study focused on a train station is detailed to better corroborate and illustrate the advantages and uses of compatible and complementing modelling approaches. As building-information-modelling awareness and use is growing, the validated mapping approach can benefit from the future application of automation procedures.

Culture change in construction industry: from 2D toward BIM based construction : geometric data exchange using the IFC standard
Nenad Čuš Babič, Danijel Rebolj, 2016, original scientific article

Abstract: Building Information Modelling (BIM) has become accepted as an approach that should deliver substantial gains to all the stakeholders within the architecture, engineering and construction (AEC) industry. Recently, several researchers have pointed out the need for cultural changes as a necessary step for radically transforming the industry. In order to provide answers to these requests, the culture should be described in a more explicit way, and industry issues interpreted correctly. This paper via qualitative research of variety of sources explores the stability and persistence of a traditional 2D paper-based approach in the light of Institutional theory. The paper illustrates how the traditional approach is embedded within AEC culture by considering the regulative, normative, and cultural-cognitive aspects. These aspects support each other, thus providing even more stability and support for the existing values and ways of working. The aim of this work is to provide some insight into reasons for slower penetration of the BIM based construction. The paper also explains the local character of the industry, which slows down transference of best practices within the AEC industry. Understanding of existing patterns reveals new insights into how to make the transition easier and more functional, especially within the contexts of existing priorities and values.

What is seen is who you are: are cues in selfie pictures related to personality characteristics?
Bojan Musil, Andrej Preglej, Tadevž Ropert, Lucia Klasinc, Nenad Čuš Babič, 2017, original scientific article

Abstract: Developments and innovation in the areas of mobile information technology, digital media and social networks foster new reflections on computer-mediated communication research, especially in the field of self-presentation. In this context, the selfie as a self-portrait photo is interesting, because as a meaningful gesture, it actively and directly relates the content of the photo to the author of the picture. From the perspective of the selfie as an image and the impression it forms, in the first part of the research we explored the distinctive characteristics of selfie pictures; moreover, from the perspective of the potential reflection of a selfie image on the personality of its author, in the second part we related the characteristics of selfie pictures to various personality constructs (e.g., Big Five personality traits narcissism and femininity-masculinity). Important aspects of selfies especially in relation to gender include the tilt of the head, the side of the face exhibited, mood and head position, later related also to the context of the selfie picture. We found no significant relations between selfie cues and personality constructs. The face-ism index was related to entitlement, and selfie availability to neuroticism.

InpPro training environment and model based working in construction
Nenad Čuš Babič, Danijel Rebolj, Thomas Olofsson, Sebastian Schumacher, 2009, published scientific conference contribution

Abstract: InPro project is European initiative which is developing a model based and collaborative way of working in early design phase in construction. To support project goals and facilitate the industrial transformation and industrial technology take-up, the project implemented tools and developed curricula and materials for training and education of management, architects, engineers, and construction workers, as well as university students. The paper presents training environment architecture with BIM laboratory that was developed to support training on model based work practices and enhancement of hands-on skills. Development process, technical solutions and experiences are described. Content of training courses and curricula is based on experiences from live project demonstrations and use cases. The paper presents one of the answers that address the problem of insufficient skills in construction industry that prevent adoption of novel methods of working and technology.

Optimizacija informacijskih tokov v gradbenih projektih kot osnova za učinkovito strategijo uvajanja informacijskih tehnologij
Nenad Čuš Babič, 2011, dissertation

Abstract: Zaradi nenehnih pritiskov po skrajševanju rokov in zniževanju cen gradbenih storitev se podjetja na področju gradbeništva stalno soočajo s potrebo po večanju produktivnosti in ena izmed možnih rešitev je industrializacija gradbene proizvodnje. Industrializacija gradbenih procesov zahteva visoko stopnjo avtomatizacije in v tej točki se gradbena industrija sooča s številnimi problemi. Večina manjših in srednje velikih podjetij, ki v stroki prevladujejo, uporablja IT na zelo nizki stopnji. Še posebej so težave povezane z vzpostavitvijo in upravljanjem ustreznih informacijskih tokov, vzpostavljanjem interoperabilnosti med udeleženci in s tem povezanimi informacijskimi sistemi. V gradbeništvu se za potrebe izmenjave informacij o gradbenem objektu uveljavi koncept informacijskega modela zgradbe (Building Information Model – BIM). BIM gradbeni objekt opisuje celovito in nedvoumno ter v več dimenzijah. Je objektno zasnovan načrt zgradbe, ki vsebuje informacije o posameznih elementih – delih zgradbe – vključno z njihovimi atributi ter povezavami. Z uporabo BIM dosežemo enoten dostop do informacij za potrebe različnih panog, ki v gradbenem projektu sodelujejo. Vendar pa vpeljava koncepta modelno zasnovane gradnje v prakso kljub velikim naporom raziskovalcev in industrije še vedno ne poteka dovolj učinkovito. V pričujoči raziskavi smo opravili analizo obstoječe prakse upravljanja z informacijami o objektih ter analizo pristopov k prehodu iz tradicionalne v modelno zasnovano gradnjo. Kot orodje analize smo uporabili ogrodje, ki ga je v sklopu institucionalne teorije definiral Scott [Scott 2004] in v katerem so opredeljeni tipi nosilcev institucij. V analizi smo 2D načrtovanje obravnavali kot institucionalizirano obliko delovanja in preučevali njegovo togo vpetost v procese in metode, ki se uporabljajo v gradbeništvu. Želeli smo predvsem osvetliti razloge za stabilnost 2D pristopa v gradbeni in arhitekturni praksi. V drugem delu analize smo izsledke dveh izbranih velikih evropskih projektov umestili v splošno ogrodje procesa institucionalizacije povzetem po Tolbert & Zuckerjevem modelu [Scott 2007]. Namen tega dela analize je preučevanje sodobnih pristopov k prehodu v modelno gradnjo in postavljanje temeljev za boljše strateško odločanje pri nadaljnjem razvoju modelno zasnovane gradnje. Ključno vlogo za transformacijo gradbene industrije imajo mehanizmi, ki oblikujejo motivacijo za uvedbo sprememb, zato smo temu posvetili posebno pozornost in pokazali pomen ekonomskih učinkov v primerjavi s tehnično odličnostjo uvedenih rešitev. Osredotočili smo se še na v sedanji praksi manjkajoče vloge in druge organizacijske vidike. V zadnjem delu smo na študiju primera pokazali kako lahko spoznanja izvedene analize uporabimo pri inovacijskih procesih v gradbeni industriji. Razvili smo prototip celovite organizacijsko-informacijske rešitev za vpeljavo modelno zasnovanega spremljanja gradnje in upravljanje z materialnimi tokovi. Na osnovi analize vlog udeležencev in ustaljenih delovnih procesov smo pripravili model informacijskih preslikav, ki zagotavlja večjo transparentnost materialnega toka. Omenjena preslikava obravnava posplošitve posameznih gradbenih elementov na nivo tipa/vrste elementa, pri čemer je potrebno ločiti identiteto posameznega načrtovanega gradbenega elementa od identitete fizično izdelanega gradbenega elementa. Navedeno področje smo izbrali, ker med seboj povezuje prej slabo povezana segmenta masovne proizvodnje in inženirskega načrtovanja in ima zato velik potencial za uspešno vpeljavo novih pristopov. Po drugi strani je upravljanje materialnega toka eden izmed bistvenih virov neučinkovitosti gradbene proizvodnje, ki ga z uporabo obstoječih pristopov temelječih na 2D načrtih ni mogoče učinkovito izpeljati. Pri oblikovanju opisane rešitve smo se držali načela, da morajo demonstracijski projekti pokazati predvsem ekonomske učinke in ne prevladujoče tehničnih, saj je vodilni mehanizem sprememb v gradbeni industriji večanje pridobitev.
