This project aims to enhance the accuracy of earthwork estimation using UAV-mounted LiDAR and RGB sensors to improve 3D modeling of large-scale construction sites. The study will include a two-part case study: a workshop to educate stakeholders on UAV-based modeling and a field demonstration showcasing real-world applications for earthwork planning and management. By integrating advanced surveying technologies, the project seeks to reduce cost overruns, optimize material usage, and improve efficiency in balancing earthwork quantities for large infrastructure projects.
