The purpose of this study is to suggest the development direction of a BIM performance assessment tool. To do this, a series of focused group interviews were conducted with BIM experts in South Korea regarding the objective, characteristic, potential problems of a BIM performance assessment tool. A survey questionnaire was developed based on the focused group interviews and distributed to practitioners through four different occasions. The survey results showed that there were the significant differences between practitioners by their field and years of experience about the objective, characteristic, potential problems of a BIM performance assessment tool. Based on the survey results, the consideration factors for developing a BIM performance assessment tool was suggested.

The automated quantity take off technique using BIM authoring tools has been recently issued, and the studies of this method for the accuracy, efficiency, and the unit computing for the simple volume, area and number have been developed. Meanwhile the main concerns such as the details for the level of modelling, and the costs and time for the calculating BOQ item are still required to study. In this paper, the earth works, drainage works, pavement works, and facility works using BIM authoring tools are designed in 3D, and the applicability of automated quantity take off technique using BIM authoring tools is discussed, respectively. As a result, automated quantity take off are limited in the earth works, drainage works, pavement works, and facility works. But Most items of BOQ can be supported in Re-bar model.

건축, 토목 분야의 정보 교환을 위한 표준으로 주목받고 있는 BIM 모델의 국제 표준인 IFC 표준을 위해, 소프트웨어가 IFC 표준에 맞게 유효한 정보를 입출력 하도록 도와주고, IFC 파일이 표준에 맞는지 검증할 수 있는 모듈을 개발했다. 특히, 지역별 및 국가별 상황에 맞게 BIM 모델을 수정하거나 확장해 사용하도록 권고하고 있는 상황에서 다양한 확장 IFC 표준을 효과적으로 지원할 수 있도록 IFC 표준을 정의하는 EXPRESS 언어로부터, 객체 지향 언어를 위한 소프트웨어 개발 라이브러리를 자동으로 생성하고, 해당 SDK를 활용해 IFC 모델을 검증하는 라이브러리를 자동으로 생성하며, IFC 파일을 검증할 수 있는 독립적인 실행 파일도 자동으로 생성할 수 있도록 했다. 또한 객체 지향 라이브러리를 사용함으로써 주어진 IFC 모델을 효과적으로 문서화 할 수 있도록 HTML 생성 도구를 개발하거나 3차원 형상 확인이 가능하도록 VRML 생성 도구를 개발하는 등의 작업이 쉽게 이뤄짐을 확인했다. 이렇게 자동화된 BIM 소프트웨어 개발 도구는 IFC 모델의 수정이나 확장을 고려하는 BIM 소프트웨어 개발 프로젝트의 생산성을 향상시키고, 해당 시스템의 운영에 신뢰도를 높이는 것은 물론이며, 향후 국내 실정에 맞게 운영될 BIM 인증 제도에도 활용하면 기존의 수작업 방식 인증제도에 비해 인증에 걸리는 시간과 비용을 줄이는 것은 물론 인증 자체의 객관성과 정확성, 투명성과 신뢰성을 높일 수 있을 것으로 기대된다.

The purpose of this study is to demonstrate the improvement of the education process in architectural engineering through the analysis of the advantages of the BIM tool. As public institutions and owners have been introduced to Building Information Modeling (BIM) tools, BIM has become an important factor in the design process in undergraduate university programs. First, BIM-related issues, domestic and overseas, was analyzed. Second, a case study of BIM education was analyzed at K University under the ABEEK process. Students participated a survey about the understanding of BIM and the use of BIM tools. As a result of the analysis, six advantages of the use of BIM tools were found. As a result of this research, following five issues are found about BIM education through advantage of using BIM tools. The result of this research was verified by conducting a survey on the usage of BIM softwares. The limitation of this study was to analyze the case study of only limited numbers of participants at the university.

본 논문에서는 사례연구를 통하여 RC구조 BIM에서의 물량정보 획득의 효율성을 분석하고 이를 기반으로 BIM 프로세스 환경에서의 철근 및 콘크리트 물량산출을 위한 데이터베이스를 구축하여 현장 시공단계에서의 공정 및 물량관리의 협업단계를 가능하도록 하는 철근 Sorting 시스템에 대한 연구를 목적으로 한다. 기존의 건설, 건축분야에서의 정보는 기호적 언어와 2차원 기반의 도면 정보체계를 통해 표현되었지만, BIM 기술을 통해 건물의 실제 형상과 정보를 가지는 3차원 기반의 정보체계로의 변화와 함께 컴퓨터 데이터베이스 내에서 프로젝트에 포함된 모든 정보를 저장하고, 다양한 형태로 필요에 따라 정보를 표현할 수 있게 변화하고 있다. 견적 및 시공을 위한 RC구조설계단계에서의 배근 모델은 협업을 위한 객체 정보의 획득 및 추출이 중요하지만 현재 상용되고 있는 BIM도구에서는 현재까지 미흡한 체계를 이루고 있다. 본 논문에서는 구조설계를 기반으로 배근된 BIM 구조모델 사례를 통하여 기존 BIM도구에서의 물량 정보획득 효율성 분석을 기반으로 객체들의 데이터베이스 구축을 통한 철근 Sorting 시스템 구축 연구를 통하여 협업단계에서의 체계적 물량정보 관리를 가능하도록 하였다.

In spite of advantage by using BIM as quantity take-off, schedule control and clash check, absence of guidelines is a barrier to applying BIM to road domain. In this research, domestic and overseas cases of BIM guideline are analyzed in order to develop the road BIM deliverable submission system. The analysis is classified 5 topics which are BIM submit product list, submit files format, availability of existing 2D based products, BIM authoring tools and submit process. As a result, It needs a lot of effort to standardize BIM delivery system for road domain because BIM submit product list and BIM authoring tools are changable depending on BIM use cases. However, submit files format and submit process are common part to suggest guidelines of road BIM delivery system. It requires to combine BIM and 2D products for road BIM delivery system because delivery products are not exactly alternative 2D based delivery products for the present. The authors expect this research to use as basic data for development of the BIM deliverable submission system in road domain.

Public institutions and owners have been introduced to use Building Information Modeling (BIM) tools. Learning BIM becomes an important factor in design process of undergrad program. The purpose of this study is to demonstrate an integrated architectural engineering design process using BIM tools. BIM education programs are analyzed to compare the level of detail in BIM education. An architectural engineering design class needs to involve BIM to introduce integrated process. An architectural engineering design process needs be based on understanding design, building structure, construction and building services. 3D Modeling helps understanding a building structure and checking environment-friendly element analysis. As a result of this research, new process of design education is proposed under four issues.

Today, as construction industry grows rapidly, technology has advanced throughout the whole industrial world. Architectural design phase has gone digital from the traditional method of drawing which was an important means in the past, and Building Information Modeling(BIM), an emerging new paradigm, changed architectural design process. So this paper studies the difference between a 2D-based and a BIM-based design process which are currently applied to domestic, and proposes a BIM-based integrated design process in order to help establish BIM to domestic efficiently.
