In order to apply the BIM technology effectively and efficiently during the life-cycle of project, it is important to deliver a accurate information on BIM from designer, and it should be used effectively at construction or maintenance stage. However, stakeholders have created a new BIM model at each phase in many practise adopting BIM, not used BIM generated in design stage. Because they have different purposes for using BIM, and deliver the BIM model without the sufficient explanation or application. It is necessary to define the range of usable BIM in construction phase with analyzing clearly the BIM created in design phase, and determining the difference with required BIM in construction phase. Therefore, this study propose a method for construction c

In the trend of building enlargement, high-rise and irregular shaped building, domestic application of BIM in construction phase is increasing in recent years. BIM that is based on a three-dimensional, requires a specific building expression. Model expression level required for each phase such as design, construction, and maintenance of the construction project can be different. BIM model to apply in practice is difficult because it is not clear to set up the criteria for the expression level of construction BIM model. And it has a limit that is lower productivity in construction project. Therefore, this study considers the way of the improvement and analyzes the application for representation level of construction BIM model through the survey. By analyzing of the survey results, this study will be to present a basis for an appropriate expression level setting of construction BIM model.

Based on the prior research which developed the consistency review checklist of the BIM model and 2D drawing through the drawing analysis of the construction documents phase, the apparent limits of the existing template and the template development items were derived. As well, the BIM-based drawing templates of the construction documentation phase were developed and verified using ArchiCAD BIM software. The developed template was then applied to the actual project model in the construction documents phase, and, as a result, 50% of existing work elements could be utilized as templates. This is an increase of more than 30% over the existing template utilization elements, and it is analyzed to be effective in practical application and utilization. Based on the results of this study, if the BIM model construction criteria matching the drawing's utilization purpose are presented, while at the same time the BIM data interlocking and drawing template development studies are conducted, the utilization of BIM data can be maximized and additional drawing work can be minimized to increase the percentage of template utilization elements. In addition, it is believed that this can employed to address functional and institutional problems of BIM-based drawing and make a contribution to the activation of BIM.

국내 외 건설공사에서 건물의 전 생애주기 동안에 발생되는 정보의 관리 및 통합이 가능한 BIM 적용이 활발해지고 있다. BIM을 시공단계에 활용할 경우 공기단축, 재시공 감소, 협업능력 향상 등의 효과가 있다. 그러나 국내 BIM 지침서 정의수준 부족, 설계 기준의 미비 때문에 시공단계에 BIM을 적용하는데 한계가 있다. 특히, 설계 단계에 비해 시공단계에서는 MEP 분야는 그 중요성이 훨씬 커진다. 따라서 본 연구는 시공단계의 MEP 분야에서 BIM활용도를 높이기 위하여, 시공 BIM MEP 모델 요구조건 체크리스트를 개발하였다. 체크리스트 개발을 위하여 국내 외 BIM 지침서 및 시공 BIM이 적용된 민간 공공 공사의 사례를 분석하였다. 지침서 및 사례를 토대로 작성객체 31개, 속성기준 31개, 총 62개의 시공 BIM 모델 요구조건을 도출하였다. 도출한 62개의 요구조건을 활용목적과 필요사항으로 구분하여 시공 BIM MEP모델 요구조건 체크리스트를 제안하였다. 본 연구에서 제안한 체크리스트를 실무에서 활용한다면 시공단계 MEP BIM 모델의 활용도를 향상시킬 수 있을 것으로 기대된다. 또한 학문적인 측면에서 시공단계 BIM 모델의 표준화된 지침서 개발에 활용될 기초연구로서 의미가 있다.

This paper aimed to identify potential opportunities of building information modeling (BIM) utilization for construction risk management. Construction risk factors and BIM functions were derived through conducting in-depth literature review. Nineteen construction risk factors could be resolved by various BIM functions. Phase planning, site analysis, design authoring, and 3D design coordination were identified as the most efficient BIM functions for construction risk management.

Since it is common that design BIM data created by designers and engineers do not afford to consider constructability for the site, it is usually necessary to optimize the design BIM data to construction BIM data. While this optimization process requires various design updates depending on the construction methods and requirements, most designers in the projects do not participate the construction phase, which can arise another obstacle factor in utilizing construction BIM. In order to prevent this issue, we need cooperation system, where all the parties work together from the initial stage of project to create quality assured BIM model. However this kind of system is not realistic in Korea with most of the working processes being conventional yet. Therefore, at this point of time, it is realistic for us to secure basic construction qualities in the design phase and keep those qualities by the construction phase. This study suggested a relevant quality management plan for BIM usage in construction phase.

Construction plans for large construction projects are problems such as Incompatibility of information, omissions due to technical limitations of 2D CAD. In addition to, Plan established for the validation such as process, cost and construction technology plan is difficult. By occurring Frequent changes in the course of business, Inefficiency of management has occurred. In the construction process, there is occurred costs and construction delays due to reconstruction or communication error. In this study, It was deemed BIM will complement Existing 2D CAD problem. And, BIM case studies in the construction phase of domestic construction were analyzed, How to apply BIM in the construction phase investigated.

BIM(Building Information Modeling)은 원칙적으로 건설 전 생애주기에 걸쳐 활용되어야 그 효과를 극대화 할 수 있으나, 아직은 계획 및 설계단계에 비하여 공사단계에서는 그 활용도가 상당히 낮은 수준이었다. 최근 대형 국책사업이 발주, 시공되면서 효율적인 공사관리를 위한 방법으로 3D 성과품 검토나 4D 공정관리 등 BIM기법 중 일부가 도입되고 있다. 본 연구에서는 토목시설물의 공사단계에서 BIM 활용방안에 대하여 제시하였다. 토목공사의 종류별, 관리 분야별 BIM 활용방안에 대하여 논의하고, 서울 지하철 919공구에 실제로 적용하여 그 효용성에 대하여 분석하였다. 특히, 현장에 구축된 BIM 기반의 웹 공사관리 시스템은 공사중, 현장과 본사를 비롯해 발주처와 감리단 등 다수의 공사 주체들이 BIM을 보다 효과적으로 사용하도록 함으로써, BIM의 공사단계 활용성을 높일 뿐만 아니라 유지관리 단계까지 확장하여 이용될 수 있다.

The domestic construction industry recognize that review of design and construct-ability has the devastating effects. The way to take advantage of BIM for increase the possibility of discovered the design errors in advance are being discussed a lot recently. Since 2012, Public procurement published that the Turn-key project which is the more than 50 billion won in construction have to let the BIM-based design be mandatory. However, people expected the advent of BIM technology can resolve the existing design errors. But the situation is the connection of design stage and construction stage is very insufficient in domestic. Therefore, in this study understanding the types of design errors in construction phase. according the review of design errors before construction. Then can acceleration the application of BIM to improve the workability in a construction site.

Building Information Modeling (BIM) and modular construction are regarded as important technologies that could contribute to overcoming the crisis faced by the construction industry. However, BIM uptake in current modular construction projects is limited. Moreover, there are no specific guidelines to support decision-making regarding the application of BIM in modular construction projects. Therefore, this study aims to analyze the possibility for BIM uptake in each phase of modular construction projects in Korea. Initially, the literature detailing on BIM uptake cases in modular construction projects was reviewed. The detailed work and activities for each phase of a modular project were analyzed via a questionnaire targeting domestic modular experts, to derive items requiring improvement due to errors or changes occurring in the actual project. Ten realistic BIM uptake items were derived, reflecting the results of literature review and expert interviews. Then, the BIM uptake items in each phase were analyzed in terms of necessity and efficiency via a second questionnaire using five-point Likert scales. Finally, the BIM utilization index (BIM UI) of the BIM uptake items was suggested as a priority measure. As a result, the BIM UI of "3D coordination" (U2), "design authoring and reviews for off-site fabrication" (U3), and "detailed 3D modeling for off-site fabrication" (U4), were assigned the highest priority. The results of this study can be used as guidelines to support decision-making regarding the application of BIM in modular construction projects.
