## 7 Discussion  
The integration of virtual reality (VR) and augmented reality (AR) technologies holds significant potential for enhancing construction projects [32]. These innovative tools offer valuable contributions across various aspects of project development and management. VR enables engineers and designers to visualize projects realistically before actual construction begins, facilitating detailed planning and necessary adjustments. On the other hand, AR supplements the real-world environment with three-dimensional models and additional information, aiding project stakeholders in better understanding intricate details [33]. Furthermore, both VR and AR prove instrumental in workforce training, providing a safe and immersive environment for skill development, consequently reducing on-site accidents and improving overall performance [32]. These technologies also play a crucial role in monitoring project progress, allowing for interactive models that offer insights to supervisors and clients, fostering better communication and understanding. Additionally, they contribute to data-driven decision making, empowering project managers and engineers to analyze real-time data and provide effective solutions promptly [34]. The findings of the case study are closely aligned with the existing literature, highlighting several key aspects. The case study results underscore the importance of data analysis and the use of aerial imaging techniques in project analysis before implementation. This aligns with

The use of drones in the case study, particularly with PIX4D software for data analysis and creating three-dimensional models, directly reflects the importance of these technologies in achieving high accuracy in estimations. Process Improvements and Efficiency  
The case study demonstrates improvements in construction processes and increased efficiency, consistent with studies such as [7, 13]. Applying drone technologies for project monitoring contributes to efficiency improvements by reducing the gap between expectations and reality, hence minimizing errors and delays. Drones provide a comprehensive view of the project lifecycle through regular monitoring, facilitating efficiency improvements, and error reduction. The case study aligns with the literature [9, 12] discuss enhancements in planning and coordination for construction projects. Using drone data to improve design and structure distribution contributes to better coordination between work teams and reduces conflicts in execution. Drones' contribution to planning and coordination improvements is evident in the case study results. Safety and Security Enhancements  
The case study findings correspond to the literature [9, 12, 36] discussing improvements in safety and security in construction projects. Using aerial imaging to analyze data helps identify potential risks and implement appropriate prevention strategies, consistent with safety and security compliance outlined in BIM. Compliance with safety and security laws and the implementation of measures based on prior drone monitoring are highlighted in the case study. The case study results are linked to the literature [14, 15] emphasizing improvements in transparency and communication among all project stakeholders, enhancing productivity. Providing regular reports to stakeholders using data derived from drones increases transparency and enhances communication between the involved parties. Drones facilitated the monitoring of supply operations and process execution, aiding communication among workers and project stakeholders in the case study. The literature [22, 24] indicates the use of modern techniques such as drones in constructing three-dimensional models for projects.
