IAI의 IFC를 기반으로 강 교량을 구성하는 부재의 상세 설계 정보를 표현하기 위한 방안을 제시하였다. 이를 위해 먼저 강교 부재 상세 설계와 관련한 설계기준, 구조계산서, 상세설계도면을 분석하여 실무에서 다루어지는 설계 데이터 항목과 이들의 표현방식을 분류하였다. 설계 항목을 기존 IFC 모델로 표현 가능한 것, 추가 모델이 필요한 것으로 나누었고, 보강재, 격벽, 현장 연결부, 그리고 전단연결재를 보다 체계적으로 표현하기 위한 속성 및 위상관계를 정립하였다. 마지막으로 본 연구를 통해 제시된 데이터모델을 기반으로 설계 정보 입력을 위한 프로그램을 구현하였다. 테스트용 교량에 적용하여 물리적 STEP 파일 생성함으로써 제시한 데이터 모델의 논리성을 확인하였다.

In recent years, numerous studies have attempted to extract quantity data by using Building Information Modeling (BIM). In terms of open-BIM based quantity take-off at the early design stage, only few studies were conducted in the field of cost engineering. A lack of compatibility of open BIM for information exchange is postulated as the cause. The Industry Foundation Classes (IFC) extension model has been developed to accommodate the interoperability with quantity take-off software. Improvement of open BIM for quantity take-off needs exchange requirements and model guidelines. For this purpose, the quantity data of IFC models were analyzed using BIM analysis tools. This paper also provides a proposal of requirements on open BIM based quantity take-off at the early design stage. Further this study have been develop the interface system for open BIM based quantity take-off requirements with the results on this study.

The Industry Foundation Classes (IFC) provides standardized product models for the building construction domain. However, the current IFC schema has limited representation for infrastructure. Several studies have examined the data schema for road and highway modeling, but not in a sufficiently comprehensive and robust manner to facilitate the overall integrated project delivery of road projects. Several discussions have focused on slope engineering for road projects, but no solution has been provided regarding the formalized parametric modeling up to now. Iterative design, analysis, and modification are observed during the process of slope design for road projects. The practitioners need to carry out the stability analysis to consider different road design alternatives, including horizontal, vertical, and cross-section designs. The procedure is neither formalized nor automated. Thus, there is a need to develop the formal representation of the product and process of slope analysis for road design. The objective of this research is to develop a formal representation (i.e., an IFC extension data schema) for slope analysis. It consists of comprehensive information required for slope analysis in a structured manner. The deliverable of this study contributes to both the formal representation of infrastructure development and, further, the automated process of slope design for road projects.
