Abstract

Building Information Modeling (BIM) is a key technology in the construction industry's digital transformation and is increasingly being utilized in the planning, design, and construction phases. However, BIM application in the maintenance phase remains limited due to various technical constraints. This study proposes a methodology to activate maintenance BIM technology by conducting bridge condition assessments based on standardized procedures utilizing BIM. Several new methods were proposed in the research, such as using an integrated information model by inserting defect elements into a structural model, data linkage between structural members and damage, constructing a database using COBie, and automated condition assessment procedures. The effectiveness of the proposed methodology and the accuracy of condition assessment results were verified by a proof test using a four-span PSC bridge with various types of over 250 damage.

건설산업 디지털 전환 기술의 핵심인 BIM은 계획·설계단계나 시공단계에서의 활용성이 점차 확대되어가고 있으나 유지관리 단계에서의 BIM 활용은 여러 가지 기술적 제약으로 아직 미미한 수준이다. 본 연구에서는 BIM 기반 유지관리 업무의 활성화를 위해 교량을 대상으로 한 상태평가 업무를 표준화된 절차에 따라 BIM 기반으로 수행할 수 있는 방법론을 제시하였다. 이를 위해 손상요소를 사용하여 기본 모델상에 손상정보를 추가시킨 통합정보모델의 구축 방법, 구조물 부재정보와 손상정보의 연계 및 활용 방법, COBie를 활용한 상태평가용 DB 구축방법, 자동화된 상태평가 수행 방법 등이 제시되었다. 250여개의 손상을 지닌 4경간 PSC 교량을 대상으로 제시된 방법론의 절차적 검증이 이루어졌으며 그 실효성과 상태평가 결과의 정확성이 입증되었다.
