해체공사 감리제도 및 감리비 산정체계 개선방안에 관한 연구

초록

With the expansion of urban redevelopment and reconstruction projects, the importance of demolition work has continued to grow. Demolition activities present unique challenges, including structural uncertainty, risks to surrounding buildings and infrastructure, and heightened safety and environmental concerns, which require systematic planning, monitoring, and professional oversight. In Korea, a demolition supervision system has been implemented under the Building Management Act; however, limitations remain in the qualification requirements for supervisors, deployment criteria, and supervision fee estimation, particularly for small-scale projects, for which supervision costs may be disproportionately high.. This study identifies the structural limitations of the current demolition supervision system and proposes improvement measures from a construction management perspective. The study reviewed relevant laws and institutional frameworks and employed questionnaire surveys and case studies to investigate existing supervision practices and cost structures. The results suggest that uniform supervision criteria increase the cost burden in small-scale projects, and that supervision fees are more closely related to project duration and demolition contract amount than to gross floor area. Scenario analysis further suggests that integrated supervision within the same project site may reduce supervision costs by about 65–70% as an upper-bound estimate. In comparison, a fixed-cost plus variable-cost model indicates a more realistic reduction of around 50%. These findings support the need for flexible qualification standards, risk-based deployment criteria, integrated site-level supervision, and a more rational framework for estimating supervision fees.
