한옥 시공은 사회적 관심과 수요가 증가하고 있으나, 현장 시공 비율이 높고 시공 시 필요한 정보가 부족하다는 한계를 가지고 있다. 이에 따른 해결책으로, BIM을 한옥 시공에 접목하였을 때 부재 단위의 모델링, 유형화와 표준화, 조립 방식에 대한 정보 관리가 가능해진다. 하지만, 여전히 BIM의 한옥건축 접목을 위한 요인에 관한 분석에 관한 연구가 부족한 실정이다. 따라서 본 연구는 한옥건축에서의 BIM의 활성화를 시뮬레이션으로 모델링하여 그 요인을 분석하고자 한다. 한옥건축 BIM 활성화 요인을 도출하고 각 인자 간 상관관계 분석을 통하여 causal loop diagram (CLD)을 작성하고 각 요인을 Parameter, Dynamic variable, Stock, Flow로 정리해 최종 모델링을 완성하였다. 주요 인자의 변화에 따른 시나리오 분석 결과, 현 지원제도 및 활성화 요인을 유지하였을 때(시나리오 1) 장기적인 관점에서 긍정적인 결과가 나왔다. 한옥의 건축지원금이 증가하였을 경우(시나리오 2), 장기적으로 약 23~24% 상승한 것으로 확인되었다. BIM의 교육비가 감소하여 전문 인력이 증가한 경우(시나리오 3)는 BIM 활성화에 긍정적인 영향을 줄 수 있으나 시나리오 2에 비해 미미한 변화 값이 도출되었다. 도출된 각 요인 중 한옥 건축지원금이 가장 영향력 있는 변수로 판단된다. 추후 구체적인 변수를 적용하고 다른 관점에서 활성화 분석 연구를 진행하면 한옥과 BIM의 적용 활성화에 도움을 줄 수 있을 것으로 기대한다.

The entire construction safety is significantly influenced by proper uses of temporary structures. However, in current practices, temporary structures are used without sufficient planning and analysis on their impact on safety. Consequently, problems in worker safety and loss of productivity are frequently caused related to temporary structures. This paper introduces an approach that uses Building Information Modeling (BIM) to automatically create temporary structures as part of construction plans and identifies potential safety hazards related to the temporary structures. In this study, the type of temporary structure is limited to scaffolding. Automation algorithms were developed and applied to (1) analyze daily construction site conditions (2) create required scaffolding objects, and (3) identify potential safety hazards related to scaffolding. A case study using a real-world construction project demonstrated that scaffolding objects were properly created based on user-input and potential safety hazards were successfully identified without human intervention.

In the construction field, there has been a recent and unprecedented increase in the research and development of modernized Korean traditional buildings, This is because, in today's modern society, the basic needs for survival have already been met and more people are now recognizing the importance of the identity of our unique culture. It is therefore timeous to consider not just how to preserve and use Korean traditional buildings, but also how to develop them into more industrialized and modernized buildings in a practical way. Recently, the direction has been focused on the industrialization of modernized Korean traditional buildings, including their evolution, and development, as well as on the numerous cases where construction has been delayed. In order to industrialize modernized Korean traditional buildings, we need to standardize their form and actively introduce current IT (Information Technology). In order to achieve this, it is absolutely necessary to change from the CADD (Computer Aided Design and Drafting) system to the BIM (Building Information Modeling) system, which reflects the concept of Virtual Architecture. Therefore, the aim of this study is to discuss the possibilities of using BIM system for industrialization of modernized Korean traditional buildings, extend the foundation of the form library, and develop an intelligent modeler. It is also necessary to exemplify a case model for modernized Korean traditional buildings to which BIM is applied.

The usage of Building Information Modelling (BIM) in building projects has enabled improvement in project planning, implementation and collaboration process amongst various stakeholders within architecture, engineering and construction (AEC) industry. However, variations exist in the current practices of BIM implementation and coordination process in the industry. These variations result in inconsistent degree of BIM use across the construction industry. This inconsistency gives rise to several managerial and technological challenges such as data interoperability issues and purposeful integration and exchange of information within the BIM components. In order to tackle the issue, it is essential to analyse the different BIM approaches employed by the industry practitioners. BIM guidelines serve as a critical link between the BIM model, and its subsequent execution. They therefore provide the best reflection of BIM application and processes. This research paper aims to address the variations existing in BIM practices across the construction industry. It includes an extensive study of 21 existing, publicly available BIM-based guidelines in order to establish an understanding of the present state of practice and deduce issues and concerns related to them. All guidelines analysed in this paper are first categorised based on authorship and the release date for efficient comparison. The points of similarity and difference between them are thereby realized and outlined. In addition, the transition of project implementation process from traditional methods to BIM technology is also explained. The existence of inconsistencies in the BIM guidelines reviewed in this paper reflects the need of a BIM 'Code Compliance Check'. The Code Compliance Check will serve as a regulatory project guideline that will further improve the potential of BIM by incorporating a consistent BIM modelling methodology for the entire construction industry.

Many construction projects have used the building information modeling (BIM) extensively considering data interoperability throughout the projects' lifecycles. However, the current approach, which is to collect the data required to support facility maintenance system (FMS) has a significant shortcoming in that there are various individual pieces of information to represent the performance of the facility and the condition of each of the elements of the facility. Since a heterogeneous external database could be used to manage a construction project, all of the conditions related to the building cannot be included in an integrated BIM-based building model for data exchange. In this paper, we proposed an ontology-based facility maintenance information model to integrate multiple, related pieces of information on the construction project using industry foundation classesbased (IFC-based) BIM data. The proposed process will enable the engineers who are responsible for facility management to use a BIM-based model directly in the FMS-based work process without having to do additional data input. The proposed process can help ensure that the management of FMS information is more accurate and reliable.

Building Information modeling is playing an important role in transforming the construction industry. It helped the industry with better visualization, minimum design errors, and excellent planning of the construction activities. Time and cost saving can be effectively achieved by using BIM for any construction project. It improves information exchange between all the project stakeholders. However, the development of earthwork 3D BIM is still underway and has not been fully implemented yet. This paper presents the study of a complete process for Earthwork BIM design using Autodesk Civil 3D. A real site road construction project is used as a case study to explain the process of earthwork modeling, starting from laser scanning to 3D model. Quantity take off calculation is very important part of any road construction project so during this study earthwork volume from two 3D earthwork model is calculated. The results obtained through this study will be the basis for future work which has been concluded in this paper.

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.

Building Information Modeling(BIM) is rooted in the economic and functional advantages of maturing from paper-based 2D drawings. The paper-based design and construction drawings are typical production from BIM and using the drawing under BIM environment is needed because there is not an alternative media instead of paper-based drawings. However using the 2D drawing process based on 2D CAD for BIM environment directly has difficulties because there are significant differences in data structure between CAD and BIM. CAD is based on traditional drawings as a whole while BIM is focused on individual objects and providing various levels of information associated with the objects. It can be an obstacle to move from 2D CAD to BIM that we don't have a standard or guideline for BIM. Futhermore, the complexity of drawing in representation would be the obstacle too, so the solution is discussed in the research based on the case of Samoo Architects and Engineers.
