While general contractors often use tablets to review design and construction information, subcontractors typically rely on paper-based methods. Each of these methods has its own set of advantages and challenges. The AR-QR code approach aims to bridge the gap between paper-based and digital methods, leveraging the power of Augmented Reality (AR) to maintain the benefits of the paper-based approach while circumventing its drawbacks. This approach grants crews direct access to design and construction information by centralizing data and eliminating the need to refer to other drawings and documents. This research study addresses an issue inherent in traditional methods that the AR-QR code approach did not consider. In conventional practices, deploying drawings on-site necessitates that the crews mentally synchronize the drawing's coordination system with the actual job site. Additionally, they must mentally position and orient items to match their actual on-site locations. This process ultimately entails a mental visualization of the items on the job site to ascertain how the designed features correspond with the actual work. Such mentally demanding steps can exacerbate mental strain and increase the risk of errors. This study aims to propose a solution to alleviate this issue by enhancing the capabilities of the AR-QR code approach to facilitate visualization of the drawing's details on the jobsites.
The research methodology includes process mapping and workflow development. The outcome is a workflow that offers insights into how the AR-QR code approach could be integrated with a positioning and orientation system to achieve the goal of this study.
