Health and safety during construction remains a worldwide challenge that the construction industry is facing. The German construction industry recorded an average of 110,000 accidents per year in the period of 2010 to 2019. A discernible trend toward a decrease in occupational accidents is not visible. In this context, traditional safety planning does not seem to be able to guarantee sufficient health and safety during construction. In line with the BIM Roadmap published by the German Ministry of Transport in 2015, it can be recognized that Building Information Modeling (BIM) is supposed to be increasingly used in upcoming years. This paper aims to identify how BIM could positively impact Occupational Health and Safety (OHS) during construction. Therefore, a thesis procedure, combining quantitative and qualitative research with an in depth literature review is introduced. This study reveals a high added value of using BIM for (1) safety rule checking and design validation and (2) safety education, training and communication. BIM as a decision supporting tool has the potential to reduce the underestimation of safety hazards and improve safety reporting, which have been identified as current vulnerabilities in the construction industry. Furthermore, an added benefit to sustainability following the concept of Construction Hazard Prevention through Design (CHPtD) is illustrated. In practice, however, BIM for OSH remains unused, while those working with BIM are not familiar with safety planning. This study indicates that in order to fully utilize the potential of BIM, intuitiveness and standardization is required, while those implementing BIM and those using BIM need to be aware of and willing to exploit the potential of new technologies. The challenge now is to recognize the potential of BIM in relation to OHS and to actively use BIM for health and safety purposes. / Att skapa en säker arbetsmiljö på byggarbetsplatsen är fortfarande en global utmaning för byggbranschen. I den tyska byggbranschen inträffade till exempel i genomsnitt 110 000 olyckor per år under perioden 2010-2019 och det syns ingen märkbar minskning. I detta sammanhang verkar traditionell säkerhetsplanering inte kunna garantera tillräcklig hälsa och säkerhet under byggandet. I samband med den strategiska BIM-implementeringsplanen som publicerades av det tyska transportministeriet 2015 ska Building Information Modeling (BIM) användas i allt större utsträckning under de kommande åren. Syftet med den här artikeln är att identifiera hur BIM skulle kunna ha en positiv inverkan på arbetsmiljö och säkerhet (OHS) på byggarbetsplatsen. Studien kombinerar kvantitativ och kvalitativ forskning med en djupgående litteraturgenomgång. Resultatet visar att det finns ett stort mervärde i att använda BIM för (1) kontroll av säkerhetsregler och validering av konstruktionen och (2) utbildning, träning och kommunikation om säkerhet. BIM som beslutsstöd kan möjliggöra en mer realistisk bedömning av säkerhetsrisker och förbättra säkerhetsrapporteringen, vilket har identifierats som aktuella sårbarheter i byggbranschen. Det finns också fördelar med att implementera konceptet Construction Hazard Prevention through Design (CHPtD). I praktiken är dock BIM för arbetsmiljöfrågor fortfarande oanvänd, samtidigt som de som arbetar med BIM inte är tillräckligt bekanta med säkerhetsaspekter. För att BIM:s potential ska kunna utnyttjas fullt ut krävs en ökad användarvänlighet och standardisering av verktygen. Samtidigt måste de som implementerar och använder BIM vara medvetna om och villiga att utnyttja den nya teknikens potential. Utmaningen är nu att förstå potentialen av BIM för arbetsmiljöaspekter och att proaktivt använda BIM för att öka säkerheten på byggarbetsplatser.

Introduction (and purpose) – Since the 1970s, digital development and modeling has improved from simple digital illustrations of a building to advanced software, such as Building Information Modelling (BIM), that allows contractors to easily collaborate on a shared model. These advanced modelling systems create the opportunity to optimize planning as well as produce a higher quality product by modelling how all the various parts of a build work together and decreasing the number of potential errors that occur on-site. To better understand how BIM can improve production, this study aims to investigate the current use of BIM and potential areas of opportunity within the prefabricated housing construction sector. Method – Data was collected through semi-structured interviews with five employees of five separate companies active in the Swedish production industry of single-family houses. Additional data was collected through a survey that was shared with a total of 17 companies, three of which partook in the survey and shared it with the companies’ employees. Results – The interviews and surveys revealed limited use of BIM technology in current developmental practice, although the company representatives still expressed interest in future technological advancement. The company representatives endorsed the ability to automate work processes in both the planning phase as well as the production phase as the greatest reason for expanding future usage. The survey revealed interest in using BIM technology to provide the opportunity to reduce the number of mistakes that occur between different contractors, where collisions may occur between unique models that have not been integrated by a single system. Analysis – According to the interview respondents, the use of BIM technology could create opportunities for businesses to remain relevant by more easily integrating future technological developments. In addition, the use of BIM technology can attract new, competent personnel. The possibility of using cloud-based BIM allows a greater degree of customer involvement in projects. However, the economic value of BIM implementation is not clear as changing established work processes may require new procedures in the company. Therefore, changing to a BIM-based work system may not be economically advantageous to companies that already have a working business model. Discussion – While indicating an interest in future development using BIM, this study revealed currently limited use of BIM technology in prefabricated housing companies, where companies currently dedicate various amounts of recourses for its technological development. A larger, randomized sample would allow for a more generalizable idea of BIM use, as this study’s results could be biased by including opinions only of those who chose to respond from a limited number of companies. The volunteer method of data collection may have skewed results, as people who choose to respond often have strong opinions about the topic. However, using a mixture of interviews and surveys did allow collection of both qualitative and quantitative data and provided an initial look into current opinions about BIM as well as areas where participants believed it could help in production, even if it is not currently in use. / Introduktion (och syfte) – Sedan 1970-talet har utvecklingen av digitala verktyg gått från enkla illustrationer, till Byggnadsinformationsmodellering (BIM), en avancerad samarbetsteknologi som tillåter olika yrkesgrupper att arbeta i en gemensam modell. Tekniken möjliggör både optimeringsmöjligheter vid planering och höjd produktionskvalitet där modelleringen av en byggnad kan minska andelen kollisioner som riskerar uppstå vid montage. För att bättre förstå hur BIM kan förbättra produktion fokuserade studien på att utvärdera nuvarande och framtida potentiella användningsområden inom den prefabricerade småhussektorn. Metod – Datainsamlingen bestod av fem semistrukturerade intervjuer från fem enskilda företag inom den svenska småhusbranschen. Intervjuerna kompletterades med en enkät som delades med totalt 17 företag, varav tre företags medarbetare delade enkäten internt inom företaget. Resultat – Både intervjuerna och enkäten visade ett begränsat användande av BIMteknik i företagens arbetsmetoder, trots det uppgav företagsrepresentanterna ett intresse i framtida teknikutveckling. Företagsrepresentanterna förespråkade möjligheterna att automatisera både projektering och produktion som drivande orsaker för fortsatt teknisk utveckling. Enkätundersökningen visade ett intresse att, i deras arbete använda BIMteknik för ökad kommunikation mellan yrkesgrupper, där potentiella kollisioner mellan modeller från olika system kan hanteras på ett effektivare sätt. Analys – Användandet av BIM-teknik kunde öka företagens möjlighet att lättare implementera framtida teknisk utveckling. Samtidigt som ett högt teknikanvändande kan attrahera ny kompetent personal. Möjligheten att förlägga BIM-tekniken till webbtjänster tillåter beställare att bli mer involverade i sitt husprojekt. Trots det är det inte klart vilket ekonomiskt värde BIM-användandet ger, där implementeringen av ett nytt system kan kräva att justering av flera redan befintliga system inom företaget. Implementeringen av ett BIM-baserat arbetssystem är därför inte en självklar investering för företag som redan i dag har en fungerande verksamhet. Diskussion – Trots ett, i dagsläget, begränsat användande av BIM-teknik visade företagen i den prefabricerande småhusindustrin ett intresse i teknikens framtida utveckling, där företag dedicerar varierande mängd resurser för teknikens utveckling. Fortsatta studier föreslås genomföra med mer omfattande, och slumpmässiga datainsamlingar eftersom undersökningen, som använt ett begränsat antal företag, har krävt att respondenten har velat delta i studien och kan med det tros kunnat gett en partisk bild om ämnet. Användandet av intervjuer för kvalitativa data och enkät för kvantitativa data tillät för en bredare spektrum av åsikter att bli hörda rörande det aktuella användandet av BIM-teknik, och inom

<p dir="ltr">Building Information Modeling (BIM) supports engineering and performance analysis for buildings and civil infrastructure from the initial design stage. BIM offers engineers access to building and infrastructure objects, along with their associated data, which can be utilized across various platforms to develop analytical models. However, the interoperability between BIM and analytical models is still limited and challenging. One such limitation and challenge is in the interoperability between BIM and Building Energy Modeling (BEM). Despite the fact that interoperability of geometry and material information between BIM and BEM has been extensively investigated, the interoperability of heating, ventilation, and air conditioning (HVAC) information, which is a crucial part in BEM, was underinvestigated. Another limitation is that the shared objects frequently lose their identification across different models during the processes of their creation, design iterations, and model transformation. In addition, current building and civil infrastructure projects mainly rely on Portable Document Format (PDF) plans as the official deliverables and documents to be stored, communicated, and transferred among different stakeholders. The transition from 2D PDF plans to 3D BIM remains challenging because manually creating a BIM instance model from 2D drawings can be laborious, time-intensive, and susceptible to errors.</p><p dir="ltr">To address these gaps, this dissertational research introduces new Industry Foundation Classes (IFC)-based algorithmic methods that utilize the state-of-the-art Data-driven Reverse Engineering Algorithm Development (D-READ) method and the invariant signatures of architecture, engineering, and construction (AEC) objects to (1) develop algorithms that can extract the information from 2D PDF drawings and reconstruct the 3D semantically segmented and enriched BIM instance models, (2) develop object mapping algorithms for interfacing BIM and analytical models (e.g., BEM, structural analysis models, etc.) by automatically mapping building objects, and (3) iteratively develop the HVAC information transformation algorithm between BIM and BEM. Following the proposed methods, algorithms were developed to (1) semi-automate the creation of semantically segmented and enriched 3D IFC-based bridge BIM instance models using 2D PDF bridge plans, (2) map space objects between BIM instance models and BEM (OpenStudio model) based on their invariant signatures, and (3) transform HVAC objects from IFC-based BIM instance models to BEM with all the necessary information for energy simulation, using (1) PDF drawings for 12 bridges located in various parts of Indiana, (2) a 2-story duplex apartment building, and (3) a 2-story office building model and a 2-story residential building model, respectively.</p><p dir="ltr">The developed algorithms were tested on three cases: (1) the PDF information extraction algorithm was tested on six bridges, which achieved 97.7% precision and 94.4% recall. In addition, it decreased the time required to create bridge BIM instance models by 94.9% compared to the manual approach; (2) the object mapping algorithm was evaluated using a 4-story office building model containing 82 spaces. The results demonstrated that the algorithm attained 90% precision and 90% recall in mapping space objects. Additionally, a 4.88% improvement in the accuracy of energy simulation results was observed when compared to simulations without space mapping; (3) the HVAC transformation algorithm was tested on two models with distinct HVAC systems: a 4-story office building model featuring a boiler radiator system and a 2-story clinic building featuring a VAV system. The algorithm achieved transformation accuracies of 97.5% and 98.7%, respectively, compared to manually created evaluation models in OpenStudio. Additionally, the algorithm-generated models demonstrated satisfactory performance with regard to precision, with less than 9.6% error in total annual energy consumption compared to the evaluation models.</p><p dir="ltr">This dissertational research introduces a new IFC-based approach to fill the forementioned research gaps in BIM interoperability for buildings and civil infrastructures. It facilitates improved accessibility compared to a proprietary workflow and will contribute to filling informational gaps (1) between 3D BIM and 2D PDF drawings, and (2) between BIM and analytical models. It builds a solid foundation for achieving (1) automated BIM reconstruction using 2D plans, and (2) smooth, accurate, and fully-automated HVAC objects transformation between BIM and BEM, for complete BIM-BEM interoperability. The proposed approach can also be leveraged to further expand BIM interoperability support by providing a novel data-driven approach for building and civil infrastructure projects.</p>

The concept of a digital twin was originated by Nasa who used advanced simulation techniques during their first moon landing but has since evolved and the areas of application have broadened considerably. In recent years, the phenomenon has received a lot of attention in relation to the real estate industry in particular, which have been followed by plenty of research into digital twins within the informatics field. However, there is still a great lack of studies that focus on the supplier’s perspective of the implementation. Therefore, the aim of this study is to identify the root causes of perceived challenges with digital twins from a supplier perspective by identifying what gives rise to problems and difficulties with the implementation of digital twins. This research contributes empirically by delving into the supplier's viewpoint, enhancing theoretical understanding through the identification of underlying causes, and practically by proposing ways to manage these foundational challenges effectively. The findings underscore the importance of addressing the knowledge gap between suppliers and clients early in the implementation process, recommending organizational and technical strategies to optimize digital twin utilization and management.

Целью работы является моделирование процесса создания и поддержания в актуальном состоянии регламента создания раздела проектной строительной документации с использованием технологий информационного моделирования. Обсуждение ведется на примере процесса создания регламента для проектирования раздела «Архитектурные интерьеры», который был реализован в ГК «Страна Девелопмент». Использование регламента позволяет значительно сократить время, затрачиваемое на создание разделов рабочей строительной документации и уменьшить количество ошибок, возникающих за счет использование нестандартных решений. В ходе создания регламента были сформулированы общие правила для этого процесса, следуя которым, можно получать не формальные, а применяемые в практической деятельности документы. На основе созданного регламенты был разработан шаблон в ПО «Revit» и эталонный комплект по объекту ПЛХ ГП-15 секция 1. / The purpose of the work is to model the process of creating and maintaining up to date regulations for creating a section of design construction documentation using information modeling technologies. The discussion is based on the example of the process of creating regulations for the design of the “Architectural Interiors” section, which was implemented in the Strana Development Group of Companies. The use of regulations can significantly reduce the time spent on creating sections of working construction documentation and reduce the number of errors that arise through the use of non-standard solutions. During the creation of the regulations, general rules for this process were formulated, following which you can obtain not formal, but documents used in practical activities. Based on the created regulations, a template was developed in Revit software and a reference set for the PLH GP-15 section 1 object.
