“…Moreover, users can view the imported datasets from every possible angle, augmenting the level of immersion, especially when the visualisation is implemented in VR. Also later, after building completion, the visualisations can serve well for facility management, where possibly additional information can be added to the as-built BIM model such as described by (Wang, 2013, Shi et al, 2016, Zou et al, 2018.…”

Abstract. By adopting Building Information Modelling (BIM) software, the architecture, engineering and construction (AEC) industry shifted from a two-dimensional approach to a three-dimensional one in the design phase of a building. However, a similar three-dimensional approach for the visualisation of the current state of the construction works is lacking. Currently, progress reports typically include numerous pictures of the construction site or elements, alongside the appropriate parts of the 3D as-design BIM model. If a proper transition to a 3D design versus 3D current state were achieved, the evolved type of reports would become more comprehensible, resulting in more well-informed decision-making. This requires a single, unique software platform that is able to import, process, analyse and visualise both the as-design BIM model as well as the recorded data of the current construction state. At present however, the visualisation and interpretation of the different datasets alone requires already multiple software packages.As a partial solution this work presents a platform to easily visualise and interpret various data sources such as point clouds, meshes and BIM models and analysis results. Recent advances of gaming engines focus on and allow for an excellent visualisation of mesh data. Therefore all of the aforementioned data sources are converted into mesh objects upon importing. Moreover, gaming engines provide the necessary tools to traverse the scene intuitively allowing construction site managers and other stakeholders to gain a more complete and better oversight of the construction project. Furthermore, these engines also provide the possibility to take the immersion to the next level: incorporating the 3D entities into a Virtual Reality (VR) environment makes the visualised data and the executed analyses even more comprehensible.By means of a case study, the potential of the presented approach is showcased. The real-world construction site recordings, models and analyses are visualised and implemented in VR using the Unity gaming engine.

Industry foundation classes (IFC) is widely accepted as a promising standard for building information modeling (BIM). IFC data can be processed with many open toolkits such as IfcOpenShell and java standard data access interface (JSDAI), which greatly supports BIM research and technology development. However, IFC data is not intuitive and requires training to understand it fully. As the core of almost any IFC data, understanding geometric representation is critical in most BIM research and technology development. The official IFC schema specifications provide detailed explanations of entities and attributes in IFC, which are helpful for gaining such understanding. However, understanding the explanations in the specifications requires certain knowledge and background. To facilitate an easier understanding of IFC data and to promote a wider adoption of IFC-based BIM, in this paper, an interactive visualization of the formation of fundamental 3D representations of a selected architecture, engineering, and construction (AEC) object was created in game simulation in a firstperson view. The interactive simulation can help people gain understanding of 3D geometric formation and representation in IFC in an intuitive and speedy manner, which is expected to achieve retention of such knowledge comparable to or better than the conventional way of reading the specifications. The visualization was tested by 14 volunteers in comparison to reading the IFC schema specifications. A survey based on the experiment showed that the game simulation-based visualization was significantly easier to understand and took significantly less time to understand comparing to reading the specifications.

“…Since the participants saw the pre-play avatar safely walking through the plank, it gains more confidence and set a walking example for them to quickly walk through the plank. An MVR system (Shi et al 2016) with motion capture feature was used as the study instrument in this research. The developed system consists of an RGB-D camera, VR technique, and cloud networking.…”

The construction industry is a high-risk industry in terms of job site safety. Construction workers' unsafe behaviors has been criticized as a key driving factor of construction safety incidents. A variety of studies indicate that social influence greatly affects workers' safety behaviors. However, the social influence on workers' safety behaviors in hazardous situations has not been well explored, partially due to the difficulty of simulating hazardous situations in the real world. To overcome this limitation, this research utilized a Multi-user Virtual Reality (MVR) system with motion tracking function to simulate hazardous scenarios to study how social influence affects construction workers' safety behaviors. A hazardous virtual environment with a plank between two high-rise buildings was created to simulate the high-rise walking scenarios of iron workers in construction projects. A human-subject experiment (n=126) was conducted to investigate the role of social influence in a simulated scenario involving walking across a narrow plank between two virtual high-rise buildings. The participants walked through the plank in the virtual environment while observing different scenarios, such as seeing a person slowly walking across the plank or falling from the plank. Participants' behaviors, such as the time taken to walk across the plank, were recorded and analyzed to understand effects of social influence. The results of the experiment indicate that social influence played an important role in safety behaviors in the virtual hazardous situation. In addition, the developed MVR system is able to serve similar experiment in the future.
