Abstract

With the recent growing importance over safety management the need for advanced and technical approaches for on-site safety inspection methods has increased. Railway construction is subject to its own particular set of temporal and spatial challenges due to its unique facilities and equipment. This study aimed to investigate the field characteristics of railway infrastructure and improve the conventional field safety management methods by identifying the most appropriate features of AR technology. Group interviews and surveys were conducted with field safety experts to derive the major problems and inspection needs. Subsequently, various features of AR, such as BIM model projection, and remote conferencing, were investigated to determine their applicability to address safety issues. As a result, four problems in the current safety management process, such as 'lack of time due to the conventional inspection method and inspection of areas that are difficult to access', and three major inspection types, such as 'observance of work procedures, status of installation, adequate dimensional spacing', were identified to be improved when adopting AR based techniques. Furthermore, AR technology utilizing plans to solve safety inspection problems and effectively manage major inspection types were proposed, and a follow up survey was conducted with the same field safety experts to derive the priority of technology development.

최근 안전 관리의 중요성이 증대됨에 따라 건설 재해사고의 선제적 예방을 위한 현장 안전 점검 방식에 대해 제도 및 기술적 보완이 요구되고 있다. 특히 철도 공사는 궤도, 전차선 등의 고유 시설물로 인해 시공간적 제약 조건하에 점검이 이뤄지고 있어, 이에 적합한 안전 관리 방안이 필요하다. 본 연구에서는 철도 인프라의 현장 특성을 선제적으로 조사하고, 이에 해당하는 적정 AR 기술을 도입하여 기존 현장 안전 관리 방식을 개선하는 것을 최종 목적으로 하였다. 이를 위해 현장 안전 전문가를 대상으로 그룹 인터뷰 및 설문조사를 실시하여, 현행 안전 관리 프로세스 상 주요 문제점과 주된 점검 유형을 도출하였다. 이후 BIM 모델 투영, 원격 회의 등과 같은 AR 기능을 조사하여, 안전 문제 해결에 적용이 가능한지 확인하였다. 그 결과, '재래식 점검 방식으로 인한 시간 부족, 접근이 어려운 구간에 대한 점검 불가' 등 현행 안전 관리 프로세스 상 4가지 문제점과 '작업 절차 준수 여부, 부재 설치 여부, 부재의 적정 간격 준수 여부' 3가지 주요 점검 유형을 AR 기술 도입 시 개선해야 할 사항으로 파악하였다. 이를 기반으로 안전 점검 문제를 해결하고 주요 점검 유형을 효과적으로 관리하기 위한 AR 기술 활용 방안을 제시하였으며, 전문가 대상 설문조사를 재실시하여 기술 개발의 우선순위를 최종 도출하였다.
