Reliability of UAV in cut and fill calculation method / Muhamaad Fiddaus Ahsraf Rezuwan

In this research paper, we investigated the earthwork processing methods for construction projects, specifically comparing the Unmanned Aerial Vehicle (UAV) method and the Global Navigation Satellite System (GNSS) method. The earthwork process, crucial in construction, involves moving the earth's surface to new positions, necessitating accurate estimates for efficient project planning. The rapid development in our world has heightened the importance of earthwork processing, particularly in roadway engineering decisions. Through our study, we found that the UAV method provided more consistent and accurate results compared to the GNSS method. The UAV method demonstrated closer agreement with Land Survey (LS) measurements for area, cut volume, and total volume, with differences ranging from 0.30% to 3.92%. Conversely, the GNSS method showed larger discrepancies in several measurements, raising concerns about its accuracy and reliability. Although the GNSS method offers broader coverage and surface area measurements, it requires further refinement. Our research emphasizes the UAV method's reliability, efficiency, and potential for future applications in earthwork calculations.
