    Construction industry remains one of the most hazardous industries to work in, despite numerous efforts by researchers and practitioners to improve levels of Health & Safety (H&S) and reduce the number of accidents which occur on the construction sites. A potential method to reduce the number accidents is to educate construction workers in hazard identification and to raise their awareness of the risks they face at the construction site through the use of emerging technologies such as Virtual Reality (VR) and Augmented Reality (AR). This paper presents the first intellectual output of an Erasmus+ project titled Construction Safety with Education and Training using Immersive Reality (CSETIR), whose goal is to examine and apply such VR and AR tools to improve the levels of H&S. Through the literature review and discussions with relevant stakeholders, most appropriate training methods were identified for the development of safety educational tools in the following project phases. VR and AR technologies have the potential to train construction workers in H&S, especially those who have little experience in construction safety, workers with literacy limitations and workers that do not speak the local language. Visual training tools, especially immersive ones, also provide better retention of acquired knowledge and skills. An immersive reality safety education tool, therefore, has the potential to increase the levels of construction H&S and to reduce the number of accidents at construction sites

    Despite growing industrial interests in fully immersive virtual reality (VR) applications for safety countermeasures, there is scanty research on the subject in the context of accident prevention during manufacturing processes and plant maintenance activities. This dissertation aims to explore and experiment with VR for accident prevention by targeting three workplace safety countermeasures: fire evacuation drills, hazard identification and risk assessments (HIRA), and emergency preparedness and response (EPR) procedures. Drawing on the virtual reality accident causation model (VR-ACM) (i.e., 3D modelling and simulation, accident causation, and safety drills) and the fire evacuation training model, two industrial 3D simulation models were utilized for the immersive assessment and training. These were a lithium-ion battery (LIB) manufacturing factory and a gas power plant (GPP). In total, five studies (publications) were designed to demonstrate the potential of VR in accident prevention during the manufacturing processes and maintenance activities at the facility conceptual stages. Two studies were with the LIB factory simulation to identify inherent hazards and assess risks for redesigning the factory to ensure workplace safety compliance. The other three studies constituted fire hazard identifications, emergency evacuations and hazard control/mitigations during the maintenance activity in the GPP simulation. Both study models incorporated several participants individually immersed in the virtual realm to experience the accident phenomena intuitively. These participants provided feedback for assessing the research objectives. Results of the studies indicated that several inherent hazards in the LIB factory were identified and controlled/mitigated. Secondly, the GPP experiment results suggested that although the maintenance activity in the virtual realm increased the perception of presence, a statistically significant delay was recorded at the pre-movement stage due to the lack of situational safety awareness. Overall, the study demonstrates that participants immersed in a VR plant maintenance activity and manufacturing factory process simulation environments can experience real-time emergency scenarios and conditions necessary for implementing the essential safety countermeasures to prevent accidents.Vaikka kiinnostus virtuaalitodellisuuden (VR) käyttöön turvallisuuden varotoimissa teollisuudessa on kasvanut, tutkimuksia ei ole juurikaan tehty onnettomuuksien ehkäisystä valmistus- ja kunnossapitotoiminnassa. Tämän väitöskirjan tavoitteena on tutkia ja kokeilla VR:ää tapaturmien ehkäisyssä kohdistuen kolmeen työpaikan turvallisuuden varotoimeen: paloharjoitukset, riskien arvioinnit sekä hätätilanteiden valmiusmenettelyt ja toimintasuunnitelmat (EPR). Kokemuksellisessa ja uppouttavassa koulutuksessa hyödynnettiin kahta teollisuuden 3D-simulointimallia, jotka nojautuvat virtuaalitodellisuuden onnettomuuksien aiheutumismalliin (VR-ACM) (eli 3D-mallinnus- ja simulointi, onnettomuussyy- ja turvallisuuskoulutus) sekä paloharjoitusmalliin. Nämä 3D-simulointimallit ovat litiuminoniakkuja (LIB) valmistava tehdas, joka rakennettiin Visual Components 3D-simulointiohjelmistolla (versio 4.0) ja kaasuvoimala (GPP) Unrealin reaaliaikaisella pelimoottorilla (versio 4.2). Yhteensä viisi tutkimusta (julkaisua) suunniteltiin havainnollistamaan VR:n potentiaalia tapaturmien ehkäisyssä valmistusprosessin layout-suunnittelun ja tehtaan konseptivaiheissa tehtävän kunnossapidon aikana. Kaksi tutkimusta tehtiin LIB-tehdassimulaatiolla vaarojen tunnistamiseksi sekä riskien arvioimiseksi. Tutkimukset tehtiin tehtaan uudelleensuunnittelua varten, työturvallisuuden noudattamisen varmistamiseksi. Muut kolme tutkimusta käsittelevät palovaaran tunnistamista, hätäevakuointia ja riskien vähentämistä huoltotoiminnan aikana GPP-simulaatiossa. Molemmissa tutkimusmalleissa oli useita virtuaalimaailmaan uppoutuneita osallistujia, jotka saivat kokea onnettomuudet yksilöllisesti ja intuitiivisesti. Osallistujat antoivat palautetta kokeen jälkeisessä kyselyssä. Kyselyn tuloksien avulla LIB-tehtaassa tunnistettiin ja lievennettiin useita vaaroja. GPP-kokeilun tulokset viittasivat siihen, että vaikka ylläpitotoiminta virtuaalimaailmassa lisäsi teleläsnäoloa, tilastollisesti merkittävä viive kirjattiin liikettä edeltävässä vaiheessa turvallisuustietoisuuden puuteen vuoksi. Kaiken kaikkiaan tutkimus osoittaa, että VR-laitoksen kunnossapitotoimintaan ja tuotantotehtaan prosessisimulaatioympäristöihin uppoutuvat osallistujat voivat kokea reaaliaikaisia hätäskenaarioita ja olosuhteita, jotka ovat välttämättömiä olennaisten turvallisuustoimien toteuttamiseksi.fi=vertaisarvioitu|en=peerReviewed

    This thesis presents a prototype desktop virtual reality model entitled ‘Virtual Electrical Services’, to enhance electrical safety and design in the built environment. The model presented has the potential to be used as an educational tool for third level students, a design tool for industry, or as a virtual electrical safety manual for the general public. A description of the development of the virtual reality model is presented along with the applications that were developed within the model. As part of the VR development process, this research investigates the cause and effects of electrical accidents in domestic properties. This highlights the high-risk activities, which lead to receiving an electric shock in a domestic property and identifies at-risk groups that could most benefit from electrical safety interventions. It also examines the theory of transfer touch voltage calculations and expands on it to show how to carry out a sensitivity analysis in relation to the design parameters that are being used by designers and installers. The use of Desktop Virtual Reality systems for enhancing electrical safety and engineering design is a novel prospect for both practicing and student electrical services engineers. This innovative approach, which can be readily accessed via the World Wide Web, constitutes a marked shift in conventional learning and design techniques to a more immersive, interactive and intuitive working and learning environment. A case study is carried out to evaluate the users’ attitudes toward VR learning environments and also the usability of the prototype model developed. From the completed case study, it appears that there is sufficient evidence to suggest that virtual reality could enhance electrical safety and design in the built environment and also advance training methods used to educate electrical services engineers and electricians. The thesis includes a discussion on the limitations of the system developed and the potential for future research and developmen

    U.S. federal laws mandate that mining companies ensure a safe workplace, implement approved training programs, and promptly report work-related injuries. The mining industry\u27s commitment to innovation reflects a history of adopting advancements to enhance environmental sustainability, workplace safety, and overall productivity, while simultaneously reducing operational costs. This thesis proposes the integration of Augmented Reality (AR) technology and digital applications to enhance the surface mining industry, presenting two innovative solutions: an AR Training System and an Operational Digital System. These business solutions have been developed and applied at a surface mine in the southwest of the US, having the potential to improve the mining industry by enhancing safety, training, operational efficiency, and data-driven decision-making, which comprehends a significant step toward a more sustainable, effective, and technologically driven mining sector, contributing to the industry\u27s evolution and growth. The AR Training System leverages Microsoft´s Power Platform and HoloLens 2 capacities to provide operators with immersive and step-by-step training guides in real working conditions for Dozers, Motor Graders, and End Dump trucks. These AR guides combine 3D models, videos, photos, and interactive elements overlapping mining equipment to enhance learning and safety. The system also offers an efficient approach to data collection during operator training, which has the potential to modify the training guides based on user performance. On the other hand, the Operational Digital System addresses the industry\u27s operational challenges. It streamlines the pre-operation inspection process, tracks equipment status, and accelerates defect identification, shift timing, delays, and loaded tonnage. The system offers a holistic approach to mining operation optimization, facilitating data sharing and management among different departments, enhancing collaboration, and expediting maintenance processes

    Proof-of-Concept: Safety Hazard Identification and Impact Minimization Using 3D BIM and VR Devices Through the Case-Studies

    Construction hazard is a global issue. Despite numerous research studies, safety guidelines and procedures, fatalities and severe injuries still occur on construction job sites. This research has been performed to identify the research gaps and potentially improve worker behavior along the most hazardous tasks during construction execution using 3D Building Information Modeling (BIM) and Virtual Reality (VR) devices. A safety hazards-related questionnaire for civil engineering and construction students, superintendents, safety, and project managers across six different states including the state of Georgia was deployed. The questionnaire was distributed via an online platform to identify and approach the hazards which occur during the pre-construction design and are latent until the execution of a project. Through a case-study, qualitative, and quantitative-based analysis, the study aims to investigate many hazards that remain unidentified using 3D BIM models and integrating them through VR devices. The research focuses mainly on electrical, mechanical equipment, roofing, and concrete works during the project execution. The chi-square test was used to examine the variability of the independent factors’ hazard recognition performance when they were crossed with the dependent variables (i.e., safety training, technology usage/advanced device training) to test the hypotheses. The study\u27s findings and recommendations can be utilized by construction organizations to evaluate BIM and VR adoption and decide whether and how they should be used for hazard detection and impact mitigation. In order to emphasize on accident causation and the significance of thorough hazard recognition and appropriate risk perception, researchers created a virtual walk-through replicating acceptable actions in close proximity to specific activity risks into a VR environment. Suggestions are also made to improve course design for any construction safety training by looking at the impact of BIM in conjunction with VR on construction safety and hazard mitigation

    Using operational scenarios in a virtual reality enhanced design process

    Maritime user interfaces for ships’ bridges are highly dependent on the context in which they are used, and rich maritime context is difficult to recreate in the early stages of user-centered design processes. Operations in Arctic waters where crews are faced with extreme environmental conditions, technology limitations and a lack of accurate navigational information further increase this challenge. There is a lack of research supporting the user-centered design of workplaces for hazardous Arctic operations. To meet this challenge, this paper reports on the process of developing virtual reality-reconstructed operational scenarios to connect stakeholders, end-users, designers, and human factors specialists in a joint process. This paper explores how virtual reality-reconstructed operational scenarios can be used as a tool both for concept development and user testing. Three operational scenarios were developed, implemented in a full mission bridge simulator, recreated in virtual reality (VR), and finally tested on navigators (end-users). Qualitative data were captured throughout the design process and user-testing, resulting in a thematic analysis that identified common themes reflecting the experiences gained throughout this process. In conclusion, we argue that operational scenarios, rendered in immersive media such as VR, may be an important and reusable asset when supporting maritime design processes and in maritime training and education

    The Plant Simulator as viable means to prevent and manage risk through competencies management: Experiment results

    Making decisions and managing competences in complex systems is a challenging task to accomplish. Specifically, the process industry is known for its complexity and sensitivity to critical procedures. Recent disasters like the ‘‘Deepwater Horizon” (2010, 11 fatalities), BP Texas City (2005, 15 fatalities), and AZF Toulouse (2001, 29 fatalities), clearly showed the risk to which we are all exposed. The increasing complexity of processes, due to the simultaneous escalation of automation, optimisation and intensification processes (followed to face globalisation challenges), are moving the attention to the management of abnormal situations, which are even more complex in nature and frequent. This increasing complexity, coupled with the fact that abnormal situations may lead to irreversible losses, is imposing the adoption of adequate approaches and tools that allow for better learning and properly managing abnormal situations. The paper presents a simulation-enabled, experiment-based approach that can be used to prevent and manage risk through competencies management. More specifically, the paper presents the results of the first experiment campaign performed in a Plant Simulator (PS), the first known in the process industry domain, and shows the efficacy of using Immersive Virtual Environments (IVE) both to make decisions and to train teams (not just single operators). The experiment results presented in the paper show the effectiveness of IVE to increase the competencies and train operators and managers. In addition, they explain how conveniently the data collected by means of the PS can be used for making daily decisions to better prevent and manage risks

    Assessing the Synthesis of BIM Technology and Irish Construction Sector Health and Safety: Using 3D Immersive Environments to Improve Awareness of Risks and Hazards on Building Sites

    Ireland is currently on an upward slope in a boom period in the construction industry and it is inevitable that workforce numbers will increase. A n ew approach at engaging field workers in health & safety awareness is critical to maintaining the downward trajectory in fatality and accidents, as the numbers emplo yed in the construction industry increase. As modelling software use in design development and delivery becomes more prevalent , it enhances the designer’s ability to anticipate, spot and foresee hazards and risks in the design . The hypothesis of this paper is that the use of Building Information Modelling (BIM) can increase the awareness of construction workers to site risks and educate them on H ealth and Safety (H+ S). In creating an immersive 3d model experience with embedded or linked H+S regulatory information, codes of practice and general Health and Safety Authority (H SA guidance, it is purposed that individuals can engage with a virtual environment containing simulated hazards and guidance on the control or mitigation of these hazards. This 3d environment will be referred to as the H+S BIM Module (HSBIMM) in this document. The framework for implementation of the HSBIMM is founded upon the critical review of the standard theories and inherent assumptions contained within existing peer reviewed literature. This study is a step forward in linking BIM and Irish H+S standards. The mixed methodology used shows simplistic methods for dev elopment of a strategy for use in H+S that benefits greatly by BIM incorporation
