Building Information Modeling (BIM) comes to be implemented into architectural design, construction, and maintenance in Japan in order to convert design information thoughout a construction project. However, various problems are taking place in data transaction. It is not also clear about the role and the responsibility of the architects and the enginners in charge.There is a movement to establish a BIM manager as a general coordinator concerning BIM in Singapore and other countries, though it is not yet popular in Japan. This paper deals a BIM manager as a new profession in a construction project. The function and skills necessary to a BIM manager is analyzed, and the strategy of Japanese general contractors is discussed. General contractors from Japan are operating BIM in Singapore compatible with open system of supply chain. This style is different from the one in Japan even they belong to the same company. In this paper it is analyzed based on the survey in detail.

While the importance of barrier-free and fire evacuation design is highlighted in architectural design education, systemic analysis, and examination on such performances are still challenging due to methodological lacks. The present study investigates the effectiveness of BIM-based human behavior simulation for architecture major students' analytical examinations to promote barrier-free and fire evacuation performances. To achieve such an aim, quasi-experiments were conducted, which compare 50 students' analysis and examination scores according to the use and non-use of the simulation, and the data were collected via participants' survey and interview. As a result, T-Test and MANOVA analyses indicate that, compared with its non-use counterpart, the use of human behavior simulation better facilitates the students' (1) examination of the physical properties and dimensions for the disabled's accessibility and evacuation, (2) understanding of the bodily capacity and handicap of the disabled, (3) examination on the spatial layouts and locations of exits, (4) understanding on evacuees' urgent behaviors, and (5) responsibility as an architect. Based on previous studies, the reasons of statistical results are interpreted as the explicit observation and analytical measures of multiple numbers of virtual-evacuees and direct-experience from body range of the disabled responding to the populated occupants as what they face in authentic reality.

Building Information Modeling (BIM) provides many advantages when it is adopted in virtual design construction, to analyze constructability, etc. For this reason, advanced countries have made it mandatory to adopt BIM in public construction projects. The Korea Public Procurement Service announced that from 2016, BIM adoption will be mandatory in every construction project in Korea. Currently, however, it is not possible to fully adopt BIM in the building design process domestically because BIM-based systems have not been used broadly in Korea's building approval system (Seumter). In this research, four challenges were drawn from a focus group interview. Focusing on tackling one challenge, this paper reviewed previous research into building approval systems and the building approval systems of Singapore, the U.K. and the U.S., and identified elements of the building approval application process and presents a system to create and manage the information. The system supports the creation and management of information and 2D drawings from an IFC-based BIM model. We expect that the system will encourage designers to use BIM from the beginning of the design process and ultimately increase the efficiency of design in a BIM-based project.

The purpose of this study is to suggest the interior architecture design studio through the pedagogical method of educational technology for college students who lack self-directed learning. The pedagogical method has been organized to make a student-centered class based on the operation of existing architectural design studios. This teaching and learning method emphasizes the role of teachers as facilitators to help students lacking in self-directed learning in the design process, the BIM visualization to give students an expression of design project and the critics to give students an experience of working circumstances. The results of this study can be summarized as follows. First, This pedagogical model can improve the self-directed learning of students, accomplish the design process well through teamwork, and provide problem based learning (PBL) to settle obstacles that come up during the project. Second, through this model, students can improve their field design capacity by instructor, design feedback and criticism. Finally, This model can suggest new pedagogical methods for interior architectural design studios and management of student-centered studios.

The introduction of the BIM into the architectural service industry is currently not being conducted smoothly. The purpose of this research is to, considering the current state of the market, establish long-term strategies that will enable the BIM to successfully settle. The survey has been conducted in target of architects in order to understand pending issues. Additionally, the articles regarding BIM have been researched for the purpose of better understanding the current societal demands. Indicated by survey results, the architects agree to a certain extent upon the need of BIM for architectural designs, yet also express concerns that the BIM introduction does not guarantee betterment in efficiency. The problematic aspects of BIM introduction that have already been discussed in some policy-related studies include a multitude of complicated issues that are unable to be resolved within a short period of time: underdeveloped BIM infra, the limit of BIM software itself, political issues regarding licensing and lack of social awareness. Based on the issues mentioned above, three main areas of focus along with their respective practical strategies and tasks have been designated. Finally, this research has analyzed the current situation and its issues along with the political solutions of 12 projects, amongst which include the standard for plan drawings, licensing system improvement, cost standard and BIM introduction support. Finally this research has analyzed the current situations and its' issues along with the political solutions of 12 projects, amongst them are the standard for plan drawings, licensing system improvement, cost standard and BIM introduction support.

In this study, rebar QTO(Quantity Take-Off) was quickly produced from the BIM model prepared by Revit in the early design phase, and the available premium rates were quantitatively presented. For this purpose, the amount of rebar calculated using the BuilderHub, which specializes in calculating rebar QTO, was analyzed according to various factors such as member type, rebar diameter, building size, item type, and order length, and the effect of each factor on the rebar QTO was determined. In addition, the BIM model generated on Revit was used to establish parameters and processes required to produce rebar QTO, and proposed a rebar premium rate and a stirrup/hoop premium rate based on the BuilderHub output results. Through this study, it is expected that a rapid and efficient comparative evaluation of rebar QTO will be possible according to various structural design alternatives in the early design phase.

건설사업 전 생애주기 중 설계단계에서의 대안별 비용 예측은 사업의 수익성 및 타당성 분석을 위한 판단기준이 된다. 설계도서가 완성되지 않은 초기 설계단계에서 과거의 유사자료를 바탕으로 개산견적이 실시되고 있다. 견적자의 경험과 산정방법에 따라 물량이 상이하고 누락되는 경우가 발생한다. 최근 IT기술 발전으로 BIM 기술이 주목을 받으면서 건설 전반에 걸쳐 기획, 설계, 시공, 유지관리 기술의 패러다임을 변화 시키고 있다. BIM을 활용한 다양한 연구가 시도되고 있지만, 활용 효과는 건설 사업의 기대에 미치지 못하고 있다. 본 연구에서는 국제 표준 IFC와 견적 관련 지식정보를 연계한 개산견적 프레임워크를 제안한다. 그 결과, 초기 설계단계에서 의사결정을 위한 공사비 예측을 수행하며, 그리고 선행연구의 한계점을 일부분 극복이 가능할 것으로 기대된다. 또한, 개산견적 프레임워크는 프로세스 일부를 자동화하였기 때문에 변경에 대한 능동적인 대처가 가능하다.

In the situation where there should be a gap between the design environments of 2D drawing and 3D BIM modeling, it is unavoidable aspect to face confusion caused by parallel usage of both technologies unless the project delivery systems are entirely upgraded to 3D. Therefore, it is critical to make efforts to minimize this confusion. Meanwhile, detailed drawings have very important roles in the construction process because they do not only concretely express construction methods for a given design plan but also provide basis for quantity takeoff and construction cost estimation etc. This paper suggests a plan to standardize detailed information based on BIM standard framework in order to make BIM realize the information. In the short term, this plan provides improved environment where both BIM and CAD technologies can be applied and, in the long term, it provides bases for BIM to replace CAD technology.
