| Abstract |
Recently, the disaster rate of the construction industry has increased with high-rise, and complexity of the building, unlike the decrease in the
disaster rate in other industries. Although risk assessment is performed to reduce the occurrence of disasters, it is difficult to estimate the
risks accurately due to activity in which no disaster has occurred, and inconsistencies in the level of details of work. In this study, in order
to evaluate the risk of the major activity for the apartment construction work, the activity was identified by referring to the risk assessment
model of construction industry type by the KOSHA. The construction work types and activities were consistently organized in level of work
into nine work types and 82 activities were through experts consultation. Analyzing the disaster types that occurred during work through
KOSHA disaster cases, calculating the probability of disaster occurrence according to the type of disaster, and combining the probability of
disaster with the severity of disaster to estimate the risk assessment method was presented. Using the daily report of the construction site of
the apartment, the results of a case study confirmed the validity of the risk calculation method presented in this study. |
