Researches on the combined platform of unmanned vehicles, especially aerial, and artificial intelligence can be executed on hobbyists' level with a low budget along with inside multi-billion-dollars technological laboratories. This flexibility has allowed UAV to attract financial potentials and even to migrate them from another technological field. Nowadays, UAVs are used in many industrial fields such as photogrammetry, cinematography, monitoring, cloud seeding. In this paper, we present our work on using UAV to generate a 3D model for a construction site. The purpose of the 3D model is to analyze day-by-day the development and progress on-site, to reconfirm the construction planning, discover opportunities and eliminate potential risks.
