Abstract

This study ranges from planning phase to the detailed design phase of steel box girder bridge and proposes ways to generate semantic information of components through Industry Foundation Classes (IFC), a data model for Building Information Modeling (BIM). The classification of components of steel box girder bridge was performed to define information items required for identifying semantic information based on IFC, and spatial information items based on topology and physical information items based on functions of components were classified to create additional properties that does not support IFC by applying user-defined property set within the IFC framework. Steel box girder bridge information model based on IFC was implemented through BIM software and semantic information input interface, which was developed in this study to examine the effectiveness of the additionally created user-defined property. Furthermore, the quantity take-off of components was performed through information model of steel box girder bridge, and the applicability of the proposed method was tested by comparing the quantity take-off based on design document with the result.

본 연구는 강박스교의 기본계획 단계부터 실시설계 단계까지를 범위로 하여, Building Information Modeling (BIM)을 위한 데이터 모델인 Industry Foundation Classes (IFC)를 통해 구성요소의 의미정보를 생성할 수 있는 방안을 제시하였다. IFC기반의 의미정보 생성에 필요한 항목을 정의하기 위해 강박스교 구성요소의 설계 단계별 분류를 수행하였고, 이를 구성요소의 기능에 따른 물리적 표현요소와 위상에 따른 공간적 표현요소로 구분하여 IFC 프레임워크 내의 사용자 정의 속성집합을 활용하여 IFC에서 지원하지 않는 추가적인 항목을 생성하였다. 추가적으로 생성한 사용자 정의 속성의 유효성을 검토하기 위해 BIM 소프트웨어와 본 연구에서 개발한 강박스교 구성요소 의미정보 입력 인터페이스를 통해 IFC기반의 강박스교의 정보모델을 생성하였고, 이를 기반으로 하여 의미정보 질의를 통한 구성요소의 식별이 가능함을 확인하였다. 또한 IFC기반 강박스교 정보모델을 통해 구성부재의 수량 및 물량 산출을 수행하고, 설계도서를 통해 산출한 수량 및 물량 산출 결과 값과의 비교를 통해 본 연구에서 제안한 방법이 실제 업무에서도 활용할 수 있음을 확인하였다.
