Abstract |
| The incorporation of drone technology into construction management has profoundly changed how building projects are monitored and analyzed. Recent developments in unmanned aerial vehicles (UAVs) provide unique opportunities to capture high-resolution, time-series data, which can generate intricate and dynamic 4D models of construction progress. This study utilizes an Unmanned Aerial Vehicle (UAV), DJI Phantom 4 Pro, to produce a multi-dimensional context-rich as-built record of the 3000-capacity Amphitheatre project at the University of Ilorin, Nigeria. The building plan was set out using a South NTS 355L Total Station. From the excavation, aerial photographs were collected routinely using the UAV with the camera in vertical and oblique views. The photographs of each acquisition date were processed in Agisoft Photoscan Professional to generate orthophoto and DEM, while virtual reality rendering was done in the Reality Capture package. The aerial photography provides high-resolution 2D imageries and DEM datasets from which the building elements were extracted in a GIS environment to model the construction progress. 3D visualization bridges the gap between design and reality. The drone images of the respective dates capture the actual progress and conditions of the construction site and combining the time dimension allows for accurate tracking of the construction progress and dynamically visualizing it in 4D. |
