Quality Assurance using Augmented Reality (AR): A study on quality assurance to comply with the WKB act and the potential of AR visualisation with planned data (BIM data) on the construction site.

The new WKB act is expected to be introduced in 2025. Therefore, contractors will have to tighten up the current quality assurance system. Since the contractor must be able to demonstrate if all aspects of the building comply with regulations, everything must be properly recorded during the building process. Due to the new WKB law, construction contractors are currently looking to improve their current quality assurance (QA). It can be concluded from the literature that the technology of Augmented Reality (AR), as an application for quality management, can be beneficial. Therefore, this study investigates how the implementation of AR can contribute to quality assurance on the construction site. This study aims to develop a QA protocol describing the process and the system. This will contribute to the improvement of the current QA process. The research method used for this study is based on the engineering cycle and during this study, a QA protocol was developed and validated. A literature study was carried out to analyse the applications and associated benefits related to AR for QA on the construction site. The requirements resulting from the new WKB Act were also analysed. The current QA process of a contractor was analysed by means of in-depth interviews, whereby a process model was developed. With this analysis, the functionality requirements and process requirements for the new QA Protocol were given. Based on the results of the literature study and the interviews, the new QA Protocol was developed. The QA protocol was validated by means of an experiment and surveys and in-depth interviews, whereby predefined functionalities, processes and benefits were validated. Based on this study, it can be concluded that the designed QA protocol meets the improvement regarding the predefined functionalities and process. Furthermore, the use of the designed QA protocol will lead to better quality assurance compared to the current process, in which the visual inspection using AR works better than the current visual inspection and gains advantages. And where this designed QA protocol will help to comply with the new WKB act.
