This study explores the feasibility of Augmented Reality (AR) technology for efficient quality inspection documentation on tunnel construction sites. Conventional tunnel construction relies heavily on paper-based documentation processes, leading to potential errors and increased documentation and site inspection time requirements. Introducing AR as a digital tool offers a promising solution to address these challenges. The paper identifies potential use of AR for tunnel inspection reports. The methodology involves Design Science Research, including prototype development and a case study in a tunnel environment. The findings of the case study show that the developed AR prototype facilitates quality management and speeds up documentation processes compared to the current paper-based solutions. Despite some input detection issues and current hardware limitations, the approach presents a promising and robust solution suitable for real-world environments.
