Extended Reality and BIM 4D for Enhancing Visualization, Logistics, and Workflow Efficiency: An Application in the Mountain Environment

As the fourth industrial revolution advances, industries are increasingly integrating technologies such as virtual reality (VR), augmented reality (AR), and mixed reality (MR) to enhance traditional workflows. These technologies increase efficiency and reduce risk by enabling the early identification and resolution of potential issues. This thesis questions traditional construction management approaches and addresses the logistical and operational challenges of constructing a modular house in the mountainous terrain where access is limited to footpaths and standard vehicles cannot operate. The study focuses on overcoming logistical and operational barriers, including the transportation of tools and materials, the acceleration of construction timelines, and the reduction of risks in such a challenging environment. The research examines the applications, capabilities, limitations, and potential of VR, AR, and MR technologies in construction management. As part of the case study, a field survey was conducted to capture the current situation with point cloud data. BIM tools were used to model construction phases, simulate workflows, and optimize logistics through Gantt chart. Finally, MR application was developed to visualize construction phases and support on-site decision making. The results highlight how MR technology clearly enhances construction planning and execution in remote locations by lowering logistical errors, minimizing errors, and improving time management. This thesis provides a framework for leveraging mixed reality solutions to address the unique challenges of construction in difficult-to-access environments, contributing to the advancement of technology-driven construction management.
