This paper presents an experimental method and apparatus of augmented reality (AR) for nDimensional (nD) building information modeling (BIM). BIM allows nD information to be visualized simultaneously by architects, engineers and constructors to gain a synchronized understanding viewing from different perspectives. However, BIM is conventionally being operated on a desktop-based computer which makes collaboration less flexible, and it also creates an isolation gap between the model and reality. This isolation gap does not severely affect experienced and skilled professionals, as they can bridge the isolation gap with their intuition developed over the years. Nevertheless, users who are lack of such experience will feel the isolation gap between the digital realm and practicable reality, which could be the hurdle in project participation and decision making. AR allows virtual content to be mixed with real environment for user experience. In the context of our study, AR is functional to present the nD information of BIM, at the same time retaining users' connection with the reality. It is not just being utilized solely for presentation, but also to maximize the potential for communication, interaction and experience. This pilot study investigates effective technological approach of using AR as an effective collaboration technology combining with BIM through proposed key aspects of contextualization, customization and curation. Contextualization is significant to enable users to understand the AR content by making the presented information meaningful to the target audience, implemented thru the means of 2D annotations, animations and options comparison. This study compares both AR BIM with and without contextualization. Customization can generate unique virtual environment and content for different level of users tailored to their needs and preference to create intuitive interaction with AR BIM. Curation is crucial to provide users with a reliable experience, and to formulate a continually improving AR BIM thru log data and users' feedback. All in all, this paper explores the major aspects of contextualization, customization and curation, to distinguish effective approach in the currently "free for all" AR BIM development. Finally, an implication is provided for future study in terms of balance in information sufficiency and complexity for AR BIM.
