Abstract

Recently, quality problems of steel used for construction have been raised as a cause of building collapse and safety accidents. Accordingly, it becomes more important to secure quality through material management, procurement management, and construction management for construction used steels. However, the quality management for construction used steels is confined to technical production and process control. So, it does not provide a solution of various non-conforming steel products issues. Therefore, this study suggests improvements of the construction system to secure quality of the construction used steels. Through expert interviews, we identify the items for system improvement and derive the top priority items by considering utility through a structured Analytic Hierarchy Process (AHP). It also divided the respondents into enterprise and research groups to analyze differences, implications and future improvement issues and suggest a road map. It is expected that the priority items derived in this study could be useful as a basic data for making policy decisions to assure the quality of construction used steel.

최근 발생한 건축물 붕괴 및 안전사고 사례의 주요 원인으로 건설용 강재의 품질문제가 꾸준히 제기되고 있다. 이에 따라 건설용 강재에 대한 자재관리, 유통관리, 시공관리를 통한 품질확보 이슈가 주요 문제로 떠오르고 있는 실정이다. 그러나 건설용 강재의 품질관리 방안은 기술적인 생산, 공정관리에 국한되어 있어 최근 발생하는 각종 부적합 철강재 관리에 대한 대안을 제시하지 못하고 있다. 따라서 본 연구에서는 건설관련 제도정책 측면에서 건설용 강재의 품질개선 방안을 제시하고자 한다. 건설용 강재관련 전문가 심층면담을 통한 제도개선 과제 아이템을 발굴하고, 이를 구조화된 AHP분석을 통해 기대효용성을 고려하여 최우선 중요과제를 도출한다. 또한 응답자를 분류하여 기업과 학계/연구계의 의견을 비교 분석하여 시각차와 시사점, 향후 개선방안에 대한 로드맵을 제시하였다. 본 연구에서 도출된 우선순위 제도개선과제들은 향후 건설용 강재의 품질향상을 위한 정책적 의사결정의 기초자료로 유용하게 사용될 수 있을 것으로 기대한다.
