Unmanned Aerial Vehicle (UAV) Visual Monitoring in Construction

Abstract

Inspections on the construction site are required from one phase to another until the project is completely done. Progress of work can be run smoothly by the planning schedule based on the proper and good inspection on site. Currently, inspections at construction site experience several problems and challenges during data collection as it only depends on human sensory capabilities. The problems occur when monitoring and inspection on the progress of work are when it was conducted in quite a large area of the site. Engineers or contractors are unable to monitor activities that occur visually in all areas for a short period of time. Besides, the limitation and inability to monitor the whole area of the site from different points of view is one of the problems that contribute to the percentage’s analysis could not be implemented. The propose of this study is to monitor the progress of work that was conducted visually by using UAV technology and to analyse the visual information in the form of images to assist the monitoring of work on the construction area. This study was conducted at the construction site located on the banks of the BatuPahat river in the city of BatuPahat, Johor. The data was collected by using Pix4Dcapture for two consecutive months where each image was processed by using pix4Dmapper software to produce orthomosaic images that depict the entire study area. The result indicated that there is a progress of work that had been successfully constructed in a certain part of the construction area which could be seen visually through images processed using pix4Dmapper.
