Potential use of Augmented Reality in pre-contract design communication in construction projects

The proactive management of a design can prevent design errors. Design changes can be mitigated by using Augmented Reality (AR) prototype digital models. However, the use of these models in construction is still in its infancy. Thus, this study assessed how AR could be used to overcome traditional pre-contract design communication related issues in construction. The study used a qualitative approach. The data required were collected through interviews conducted with experts in the fields of construction and information technology. Manual content analysis was used to analyse the collected empirical data. The study revealed that design communication issues could be related to architectural design, structural design, service design, and design collaboration. AR toolkit models, 360-degree model visualisation, walkthroughs, model registration, clash detection, and digital information overlays would minimise design communication issues, while AR features would enable design knowledge acquisition and negotiation. However, in construction, technical and social challenges are found to hinder AR implementation.
