초록

건설현장의 불안전하거나 위험한 요소는 안전사고를 유발한다. 안전한 작업환경을 유지하기 위해 위험요소에 대한 경고나 주의 표지를 설치하고 있지만 사소한 부주의 등으로 때때로 사고가 발생한다. 현장에 적재된 자재나 작업을 위해 임시 설치된 가설시설물에 의해서 경고나 주의 표지가 가려지는 경우도 있으며, 작업자가 이동함에 따라 가려진 표지를 파악할 수 없는 위험도 존재한다. 안전사고를 방지하기 위해 GPS나 센서를 이용하여 작업자의 위치추적방법이 연구되고 있지만 본 연구에서는 작업자의 시야를 방해하는 요소를 제거하는 것에 초점을 두고 있다. 본 연구는 적재된 자재로 인해 작업자가 위험요소를 볼 수 없는 문제가 발생할 수 있음을 확인하고, CAD를 이용하여 이를 공사계획과정에서 작업자의 시선에서 관리하는 방법을 제시한다.

Unsafe and dangerous factors or environments on building construction sites often cause safety accidents. Sometimes, accidents happen despite the existence of warning and caution signs. Such warning signs are likely to be hidden by stacked materials or temporary facilities on site. If workers cannot see the signs when moving or working, they could be injured, sometimes fatally. Many studies have focused on each worker's position, and various systems have been developed using GPS signals and sensors. This paper suggests a method for identifying the problem of worker inability to see the unsafe factors, to manage the problem in the construction planning phase by considering things from the worker's perspective. The method uses CAD software to investigate the relation between the height of stacked materials and the visible ratio of the unsafe factor. The results of a sample project show that the changes in the height and location of stacked materials make the site safer.
