AR BIM Validation: The Prospective of Novel Applications in Site Management
Building Information Modelling (BIM) is an information management system through the building asset life cycle, which includes the phase from initial design, construction, maintaining, to final de-commissioning operating digital modelling (BSI, 2019). BIM has developed to Level 2, it has the potential to gamify the process of simultaneously validating the project with all team members and realizing the total life-cycle management that project (Edwards et al., 2015, pp. 2–3). However, workers and managers are more familiar with traditional 2D drawings workflow but have a limited understanding of 3D BIM data management and documentation. During the construction process, project managers and workers have difficulty getting an accurate measure and control of many elements’ positions and quantities from 2D drawings (Hardin and McCool, 2015). This situation is mainly caused by the model output with 2D drawings, which confirms the dimension by personal judgement or tap measurements. Augmented Reality (AR) consists of BIM is the best way to solve this problem. The reason is AR is relevant to visual augmentation, where digital graphics are combined with actual-world imagery (Linowes and Babilinski, 2017). AR BIM can act in construction as a centralised model, it can aim to capture the site dynamics such as the construction details, and help workers owe better spatial judgement in 3D placements. In this paper, we will focus on how visualisation impacts on construction management process together with 3D BIM. In the research of AR BIM validation, we hypothesize that AR applications check design validation more accurately and efficiently than 3D BIM. Our research group tests this hypothesis by designing a control-variable experiment. In the experiment, we compared two groups between 3D modelling and AR applications based on the data files, including before-questionnaire, video recordings, and after-questionnaire. After data analysing, the hypothesis is partly right. The results showed that AR BIM is much faster in checking and has a higher accuracy rate compared with 3D BIM but has a lower shooting rate. We have analysed the reason in the discussion part. Finally, it concluded that AR BIM can better support BIM in the construction process and for elements checking with the technology’s development in the future.
