초록

Owing to various safety accidents during the demolition work of a building, the permit holder's pre-construction safety inspection was made mandatory, and the authority to take measures, such as the suspension of construction, was strengthened when violations of the demolition site were found. On the other hand, a quantitative and objective evaluation system for the safety of a site has not been established because most of the risk assessments at demolition sites thus far have been conducted qualitatively. Therefore, this study aims to improve safety by establishing a risk assessment model that can monitor high-risk sites in advance by deriving the importance of risk factor items during the demolition work of the building site. The relative importance of risk factors and determined priorities was measured using the AHP method divided into five major and 12 middle categories. The weight of 'the importance of structure safety, reinforcement work' and 'the importance of demolition method of construction, method, and equipment used' was high in the major category, and 'the complexity and specialty of structure reinforcement work' were the most important factors in the middle category. This paper presents a model that can evaluate the building risk of demolition sites using these weights. The 'Building Demolition Work Site Risk Assessment Model' constructed in this study will enable proactive monitoring of high-risk sites and help improve the safety of demolition work sites using it for priority selection of the site inspection.
