Accurate and precision monitoring using unmanned aerial vehicle in construction engineering

One of the monitoring work in a construction project is preparing a pictorial progress report to obtain a clearer and up-to-date information for a construction site. Usually, the pictures taken at the side view and inside the building cannot depict the entire construction site area due to constraints and visual limitations. This study utilized UAV technology to assist the control and monitoring of weekly construction work progress at the construction site through the visual image recording of the entire construction site. The study was conducted by recording images using the UAV Photogrammetry technique weekly for a month for the entire construction project site. Images recorded each week are then processed using pix4DMapper software to produce orthophoto images to illustrate the entire study area. All orthophoto images were then analyzed to determine weekly work progress and the most active and inactive areas from the first week to the week. The study found that UAV technology can help in monitoring construction work visually and can plan construction activities in a more organized manner.
