“…Also, Petzold and Frohburg (2006) recommended that research must concentrate on approaches for streamlining the available software and modifying it to meet the requirements of architects. Therefore, extensive research is being conducted to mitigate the interoperability issues, and different ways of integration between game engines and BIM have been developed (Zheng et al, 2023, andNandavar et al, 2018). Though BIM tools have their own visualization capabilities for adding interactivity, making the model dynamic, building VR and AR platforms, and going for extensive visualization, the game engine is a suitable option for integrating BIM data (Buhammood et al, 2020).…”

Building Information Modeling (BIM) has unique features that improve safety management in construction by visually identifying potential risks. Integrating BIM with a real-time game engine is a cutting-edge idea for more effective safety management. This study aims to conduct two case studies by integrating BIM data with game engines from two aspects: 1) Construction Safety Training and 2) Pre-construction Safety Management. A framework that covers techniques for extraction of safety ideas, managing the game engine, and character modeling tools and resources is used to carry out the case studies. In the first case study, a construction site was created by Revit, and a real-life scaffolding failure accident was simulated by Unity to warn workers to prevent similar future events. The second case study was conducted on the procedure of evacuation modeling in an emergency, integrating a BIM model and Unity following distinct pathways. This evacuation modeling can be used as a training platform for the occupants to acquaint themselves with the inside facility, show directions of the shortest evacuation path from specific points, and provide necessary information on emergency equipment. Finally, the study explains how the integration of the BIM model and game engine applications can be applied for effective, straightforward, and helpful safety management with the most efficient BIM data transition.

“…In that regard, Nandavar et al (2018) devised a bidirectional data transfer solution based on industry foundation classes (IFC) for collaboration and layout safety planning. In detail, the authors highlight that exporting FBX (.fbx) or OBJ (.obj) files from BIM tools to Unity game entails several limitations, such as being a repetitive process and including loss of nongeometrical information (Nandavar et al, 2018). The solution proposed by Nandavar et al (2018) comprises two layers.…”

The solution proposed by Nandavar et al (2018) comprises two layers. One layer is responsible for parsing the geometrical and metadata of the BIM model contained in a customised XML file and importing it to the game engine (i.e.…”

“…Also, the proposed VR prototype features a walkthrough, measurement, visualisation of building elements' metadata (i.e. non-geometrical data of the BIM model), moving and deleting building elements, making points of interest and taking snapshots (Nandavar et al, 2018). Hilfert and König (2016) describe a workflow to import BIM models' geometry and material data as an IFC file into a game engine (i.e.…”

“…In particular, technological developments (e.g. graphics and tracking technologies) (Nandavar et al, 2018;Wolfartsberger, 2019) and the increased affordability of HMDs (Hilfert and König, 2016) have enabled their use in other areas of knowledge beyond HMDs' most common usage (i.e. the gaming industry) (Syamimi et al, 2020).…”

Purpose Despite the technological paradigm shift presented to the architecture, engineering, construction and operations sector (AECO), the full-fledged acceptance of the building information modelling (BIM) methodology has been slower than initially anticipated. Indeed, this study aims to acknowledge the need for increasing supportive technologies enabling the use of BIM, attending to available human resources, their requirements and their tasks. Design/methodology/approach A complete case study is described, including the development process centred on design science research methodology followed by the usability assessment procedure validated by construction projects facility management operational staff. Findings Results show that participants could interact with BIM using openBIM processes and file formats naturally, as most participants reached an efficiency level close to that expected for users already familiar with the interface (i.e. high-efficiency values). These results are consistent with the reported perceived satisfaction and analysis of participants’ discourses through 62 semi-structured interviews. Originality/value The contributions of the present study are twofold: a proposal for a virtual reality openBIM framework is presented, particularly for the semantic enrichment of BIM models, and a methodology for evaluating the usability of this type of system in the AECO sector.
