The integration of augmented reality (AR) technology across various industries has demonstrated significant utility, particularly in the retail and marketing domains. While its adoption is growing within the construction sector, particularly among larger contractors, small contractors—defined here as those employing fewer than ten individuals—continue to face challenges in incorporating innovative technologies such as AR and Building Information Modeling (BIM). One primary barrier to adoption is the substantial cost associated with implementing these technologies. This research investigates the effectiveness of low-cost AR technology solutions aimed at enhancing design communication to improve onsite safety and constructability during electrical installations. AR facilitates the overlay of virtual or computer-generated graphical objects onto real-world environments, with traditional implementations often relying on head-mounted devices (HMDs) like the Microsoft HoloLens. However, the use of HMDs presents challenges related to user-friendliness and economic viability for smaller construction firms.To mitigate these issues, this study proposes a marker-based AR approach utilizing handheld mobile devices, such as smartphones and tablets. By scanning markers—specifically quick response (QR) codes—users gain access to corresponding BIM models and pertinent information necessary for executing construction tasks. This method represents a more accessible and cost-effective alternative for onsite applications, particularly in electrical installations. Findings from this study suggest that users perceive this approach as a practical and intuitive means of facilitating electrical design communication, indicating potential for broader adoption among smaller contractors in the construction industry.
