가상 모델을 활용한 건설현장 안전관리 방안

Abstract

To prevent safety accidents, construction sites are taking various measures, such as conducting safety education for workers and installing safety facilities. Nonetheless, safety accidents occur as site conditions change under construction. Safety accidents should be prevented by proactively identifying or predicting unstable risk factors through continuous management of changing construction sites. In this study, a safety management plan for construction sites was proposed through the method of implementing a virtual model, which is part of digital twin technology, to identify unstable risk factors and environments and eliminate them to prevent safety accidents, using drones. PIX4D Mapper, which supports photographic surveying technology, merges a number of photos containing location information taken by drones, and they are converted into a 3D model file format that can be viewed by SketchUp. 3D models in SketchUp can be reviewed from various perspectives, especially through cross-sectional analysis to assess the risk of falls at the corners of the building. Unity can be used to prevent safety accidents by simulating a worker's travel path to identify or predict risk factors for physical collisions or falls.
