Abstract

Since IFC (Industry Foundation Classes) 4 is based on the representation of 3D elements for an architecture project, and does not define standardized shapes for civil projects such as roads, bridges, and tunnels etc, it has limitations in securing interoperability for exchanging a shape information model for the civil projects. Besides, since road facilities have a linear reference, which is modeled along the center alignment, it is difficult the designers to create a standardized 3D road model. The aim of this study is to configure structure elements and their attribute for a road in the perspective of 3D design for developing a shape information model for the road. To solve these issues, this study analyzes the design documents, which consist of a road design handbook, guide, specifications and standards, and then extract shape elements and their attributes of road structures. Such shape elements are defined as an entity item and we review a hierarchical structure of a road shape defined by a virtual road model. The detailed elements and their attributes can be utilized as a 3D shape information model for constructing BIM (Building Information Modeling) environment for Infrastructures. Besides, it is expected that the suggested items will be utilized as a base data for extending to IFC for a road subdividing the detailed shapes, types and attributes for road projects.

최근 표준으로 등록된 IFC(Industry Foundation Classes)4는 건축시설의 형상요소 표현에 한정될 뿐 도로, 교량 및 터널 등의 토목시설에 대한 형상표준을 정의하고 있지 않아 여전히 토목 형상모델의 교환을 위한 상호운용성에 제약이 있다. 특히 도로시설은 중심선형에 따라 모델링되는 선형적 특성을 가지며, 프로젝트 별로 형상이 서로 상이하여 표준화된 도로정보모델을 구축하는 것이 곤란하다. 따라서 본 연구에서는 도로의 형상정보모델 개발을 위해 3차원 설계 프로세스 관점에서 도로를 구성하는 구조요소 및 속성을 도출하는 것이 목적이다. 이를 위해 본 연구는 도로설계를 위해 활용되는 도로설계편람, 지침, 시방서 및 기하설계 기준 등의 정보를 분석하여 도로 구조물의 형상 요소와 속성을 추출한다. 도출된 형상은 엔티티(Entity) 항목으로 정의하고 가상 도로모델을 통해 정의된 도로 형상모델의 위계구조를 검토한다. 도출된 도로의 세부 구조 요소 및 속성은 인프라 분야의 BIM(Building Information Modeling)환경을 구축하기 위한 3차원 형상정보로 활용되며, 도로의 구체적인 형상, 타입 및 속성을 세분화하여 도로분야의 IFC로 확장하기 위한 기초자료로 활용될 것으로 기대된다.
