Recently, the application of BIM for port & harbour facilities has been increasing, as it is widely applied to the infrastructure field both at domestic and abroad. However, the port and harbour projects still have very poor facilities information management system and the application level of BIM is very low compared to other facilities. Even if BIM is applied for those project, it is very difficult to determine in advance what information is needed without an accurate understanding of the business process. The purpose of this study is to develop a BIM framework for port & harbour facilities and to examine its applicability. To do this, we structured the classification of the port & harbour facilities and constructed object-based classification system based on ISO12006-3 standard. We also derived the BIM framework requirements from the viewpoint of process, standard, interface, and information, and confirmed the linkage of the BIM object classification system in the framework item. The applicability of the BIM framework for inspection process cases of port & harbour was examined. Accordingly, this study can solve requirement setting method, which is the non - procedural and non - systematic project information, in the BIM application process of the port & harbour project with the BIM framework. In addition, the framework is expected to be integrated into the system to play a key role in the selection of project objectives, and the ability to clearly identify the information requirements required by the BIM manager to perform the project.

국내 주요 공공발주기관의 BIM 도입 환경 수준이 높아짐에 따라 많은 설계 및 시공사에서는 BIM 수행 과정에서의 실질적인 업무 생산성 향상 방안에 대한 관심이 높아지고 있다. 이에 본 연구에서는 대표적인 BIM 설계 자동화 방안으로 BIM기반 설계 과정에서 반복적으로 수행되는 BIM 라이브러리 배치작업을 자동화하는 방안을 제시하였다. 특히 직선, 곡선, 수직 평면과 곡면 등 BIM 라이브러리의 배치 대상면을 구분하고, 각각에 대해 두 객체의 중심 거리와 선형 길이에 따른 배치간격, 배치방향 등을 고려하여 BIM 라이브러리 자동 배치 모형을 Dynamo로 구현하였다. 사례적용을 통해 다양한 배치 환경 및 조건에 따라 배치가 가능하고, 작업시간도 단축할 수 있는 것으로 확인되어 지형 특성에 맞게 배치해야 하는 각종 조형물이나 구조물들의 정확한 배치가 가능할 뿐만 아니라 배치 자동화를 통해 업무 생산성도 획기적으로 향상될 수 있을 것으로 기대된다.

As the needs for the mega-sized, high-rise and irregular shape of building increase, domestic application of BIM in construction industry is increasing in recent years. In this circumstance, interests in BIM modeling and modeling detail level have been also increased. BIM that is based on a three-dimensions, requires a specific and precise building expressions. And model expression level required for each phase such as design, construction, and maintenance of the construction project could be different as its needs. Because that it is not clear to define the criteria for the expression level of construction BIM model, It is difficult to decide how detail and what to model is appropriate in the practical application of BIM model. It could be the reason why the productivity in construction project became lower and lower. In this study we consider the way how to improve the productivity of BIM and analyze the appropriate representation level of construction BIM model through the experts' survey. The results of study could suggest the basis for an appropriate expression level of construction BIM model.

Recent technological improvements have made abundant changes in construction industry. In specific, some technical applications, such as Building Information Modeling (BIM) opens up many possibilities. Some studies have articulated the use of BIM and its advantages in construction, but most of them are theoretical, not practical. This study is to provide an insight to such obstacles in BIM research. By investigating a real project that could utilize BIM in planning and construction phases, the authors try to investigate a possible outline of advantages in BIM implementation. The study area was set to a railway construction site in South Korea. The site covers a multiple railway tracks, stations, telecommunication facilities, infrastructure facilities, railway structures, and so numerous. In the site, the authors have identified 12 errors in 7 projects that could be prevented if BIM was utilized before the construction.

Recently, research on the application of BIM has continuously been active not only in architecture but also in civil engineering in order to improve work efficiency across the project's planning, design, construction and maintenance phases. However, the empirical applications of BIM targeting to civil engineering scope of construction sites still lags compared to architectural sized projects. This is because BIM tools are mainly based upon vertical structures of architecture, thereby most of them have difficulties and limitations to get utilized on horizontal structures of civil engineering. Therefore, this study intends to propose automation technology of design using BIM library and to indicate its field availability through case application on a railway project representing linear infrastructure. In addition, it put forward the utilization plan of the automation technology upto 4D and 5D by continue making use of the BIM model created in the project's design stage up through the maintenance stage. The novel method of the technology proposed in this paper incorporates the automatic creation of the BIM library based on two-dimensional tunnel cross-sections and sweeping of it over three-dimensional alignment to create a BIM model of linear infrastructure. The proposed technology is anticipated to improve the efficiecny of modeling process of railway projects based on linear structures.

BIM과 모듈러 공법은 건설 산업의 위기를 극복하는데 도움이 되는 중요한 기술로 인식되고 있다. 그러나 현재 국내 모듈러 건축 프로젝트에서 BIM의 활용은 미미한 수준이며 구체적인 활용지침이 제시되지 못하고 있다. 이에 따라 본 연구에서는 모듈러 건축공사의 현장시공계획단계를 위한 BIM 활용성 분석을 목적으로 하였다. 첫째, 기존문헌 고찰과 전문가 인터뷰를 통해 적용 가능한 BIM 업무를 선정하였으며, 모듈러 건축공사의 시공계획서를 분석하여 BIM 활용 업무를 5가지로 분류하였다. 이후 설문을 통해 각 항목에 대한 BIM 활용성을 필요성과 효율성으로 분석하였으며 이를 BIM utilization Index(BIM UI)를 통해 제시하였다. 설문 결과 모듈간 접합부 시공상세도 구축, 양중계획 검토, 기타공사 주요 시공부위의 상세도 구축, 현장공정 계획 검토, 그리고 현장배치계획 검토가 0.811, 0.787, 0.770, 0.729, 0.699 순으로 분석되었다. 이후 사례연구를 통해 BIM을 적용한 BIM 기반 시공계획서를 도출하여 전문가 자문을 실시하고 논의하였다. 본 연구의 결과는 향후 모듈러 프로젝트에서 BIM의 적정한 활용 방안을 제시하는데 활용될 수 있을 것이다.

Recently, interest in the necessity and practical application of BIM (Building Information Modeling) is also increasing in the civil engineering field. However, there are difficulties in building BIM models and utilizing BIM modeling in the civil engineering field due to various reasons. To this end, it is necessary to develop management tools and research on management methods that can effectively utilize the BIM library in the civil engineering field. Libraries in the civil engineering field are complementary to each other, so library management in consideration of library management in various combinations and continuous updates is important. BIM library management was proposed through the development of a management tool that reflects these characteristics, which is expected to contribute to improving productivity in the field of civil design.

BIM은 지금까지 건설업무에 적용하는데 많은 시행착오를 겪어 왔다. BIM인 이슈화된지 10여년이 지났지만 활성화가 안 되고 있는게 현실이다. 본 연구는 철근콘크리트공사에 BIM적용을 제안하고자 한다. 철근콘크리트 공사는 건축공사비 중 가장 큰 비중을 차지하는 반면에 재료의 수가 적고 한정적이다. 또한 구조물 공사에 대한 모델링을 하여야 다른 모델링을 할 수 있으므로 철근콘크리트공사의 3D모델은 모든 3D모델링의 바탕이 되기 때문에 3D 모델링을 가장 처음 하여야 한다. 철근 콘크리트공사에 대한 수량산출 프로그램개발 및 사례를 통하여 BIM기반의 철근콘크리트 공사에 지식기반의 수식DB를 적용하여 시공단계까지 활용할 수 있는 BIM기반의 산출정보를 구축하였고, 적용성을 검증하였다. 이로써 BIM기반의 타 공종도 구현 가능성을 제시함으로써 정보화, 지능화 시대에 건설산업도 BIM기반의 활성화가 가능하다는 것을 확인하였다.
