최근 국외 건설사들은 BIM 설계를 통하여 건설 생산성 및 품질향상의 효과를 얻고 있다. 반면에 국내의 BIM 설계는 추가 비용 및 전문 인력부족 등의 문제로 침체되어 있는 실정이다. 건설경기의 불황 등의 이유로 건설시장 규모가 축소되어 있는 시기인 만큼 일차적으로 공공기관을 중심으로 BIM 설계를 활성화하여 설계 초기 단계뿐만 아니라 시공분야까지 BIM을 적극적으로 도입하고 그에 따른 성과의 확산 및 국내 BIM 기술발전을 도모할 수 있어야 한다. 본 연구에서는 BIM 설계 활성화를 위해서 일차적으로 공공기관의 BIM 설계를 활성화시킬 수 있는 방안을 제시하였다. 이를 위하여 한국토지주택공사(LH) 사례를 통하여 BIM 설계 추진상의 문제점들을 분석하였고, 그에 따른 개선방향 및 구체적인 설계 적용 방안을 제안하였다. 또한, 제시된 방안을 단계적으로 수행하기 위해 "LH BIM 설계 적용 로드맵"을 수립하였으며, 그에 따른 기대효과를 제시하였다. 제안된 연구 내용은 한국토지주택공사에서 시범사업으로 적용될 예정이다.

In process of creating BIM model for tunnel, many user use still CAD, so the workflow for BIM design is not perfect. Therefore, in this paper, we proposes a method to automatically create BIM model without converting 2D drawings in tunnel design. It can allow engineers to design BIM-based tunnel with maximum use of linear information and modify the BIM model whenever there is changed linear information. To do this, we use Dynamo, which can reduce the time required for creating and modifying BIM models during design changes, saving time wasted for BIM conversion design.

중소규모 설계사무소에서의 BIM(Building Information Modeling) 활용은 BIM 라이브러리 및 기술콘텐츠 등 요소 기술의 부재로 인하여 아직까지도 미흡한 실정에 놓여있다. BIM을 도입하고 활용하는 설계사무소의 기술적인 부담을 최소화하기 위해서는 BIM 라이브러리 및 기술 콘텐츠를 제공하고, 단일 BIM 정보를 다양한 용도로 공유 및 교환하는 체계가 필요하다. 왜냐하면 BIM 설계는 단순히 3D 형태로 건물의 외관만을 설계하는 것이 아니라 공사에 들어가는 물량을 산출하고, 자재 정보 등을 바탕으로 기술에 관한 설계정보 등을 제공할 수 있어야 하기 때문에 기술 콘텐츠의 마련이 필수적이라고 할 수 있다. 따라서 본 연구는 설계 업무 단계에서 BIM 데이터와 기술 콘텐츠가 연계 사용될 수 있도록 시스템 모듈 개발을 통해 BIM 기술 콘텐츠를 보급함으로써 BIM 기반 설계 업무의 효율성을 높이는 데에 목적이 있으며, 개발된 BIM 기술 콘텐츠 데이터 활용 시스템 모듈을 통하여 BIM 저변이 확대될 수 있는 근간을 마련하고자 한다.

The objective of this paper is to introduce a curriculum for BIM design and explores characteristic of BIM Design. In order to get our approach, conducted by means of BIM throughout an actual experiment by elementary school from Architectural programming, preliminary design to design development and construction drawing. The experiment states that curriculum for BIM design requires systemically to be made in the architectural education. And also schools integrate BIM teaching early into in their curriculum. Some schools claim that BIM is often perceived as stumbling block student' creativity on account of its instant building elements. But this is not so; it all depends on how BIM is taught in the architectural education. The results state that students in the architectural school today is required to learn design by means of BIM early in the first year. Also more importantly, in order to advance the BIM design, a curriculum for BIM design is required to diversely open class in the architectural education.

While previous studies argue that BIM-based assembling collaboration promotes the communication and process management among participants in architectural design projects, it is still unknown which communication and socio-psychological factors are more and less activated in use of BIM-based collaboration. To investigate this research aim, in authentic BIM-used architectural retrofitting projects, the participants (N=36) collaborated and assessed the communication factors on (1) perceiving design results, (2)understanding partners'design intention, (3) proposing and converging opinions, the interpersonal design process management factors on (1) managing design process, (2) managing collaboration schedule, and the complementedness factors on (1) understanding partners' expertise, and comradeship. Statistical analyses reveal that the factor relevant to perceiving design results is better activated than the other factors (p<0.05), but all other factors are not much activated compared to perceiving design results. Deduced from the previous BIM studies and interviews, a reason roots in the shared forms and semantics of BIM. The shared semantics represent collaborators' information and allow the participants to perceive design changes explicitly. Meanwhile, BIM-based assembling collaboration is limited to represent observable, experience-able processes of design, and thus, several key socio-psychological factors, such as proposing and converging opinions and managing design process, are less activated.

Although BIM has been recognized as one of the main streams that advance the construction industry worldwide, it is difficult to ensure the quality of BIM data due to the problems such as internal errors of BIM tools and lack of guidelines that enhance design quality. Such problems cause designers, constructors, and project owners to hesitate applying it to their business. The main objective of this research is to develop a BIM guide for public project owners that is to be usable at the design phase of the public projects. To meet the objective, the study invited 10 BIM experts from Korean construction industry and operated workshops with focus group interview methodology. As well, a number of BIM guidelines from the BIM advanced countries were reviewed to identify valuable contents for the guide. There are four main parts in the guide developed: BIM design procurement process guide, Request for Proposal development guide for BIM design, BIM execution plan development and evaluation guide, and BIM output and deliverables review and evaluation guide.

In order to boost productivity and efficiency of architectural design, architect accumulates materials and details which are repeatedly used. According as introduction and application of BIM (Building Information Modeling) have proliferated, a number of data are being produced. BIM data constructed in a stage of architectural design reduces repetitive works of design and can be used in estimate and construction, maintenance. BIM library gathered these data are able to enhance participants collaboration and design improvement. Library is a vital factor in BIM and a number of libraries are needed as BIM introduction and application have proliferated in architecture industry. However, BIM Library establishment and related research development are incomplete. And specific standard setting and institutional environment for BIM library building have not been achieved. As such a vast amount of information are generated but there is no systematic plan and reuse frequency is low. So it is necessary to build system for effective data sharing and operation management. In this study, through establishment of BIM standard system and construction of management environmental system, it has an object in view for developing framework which can efficiently manage various libraries happened in BIM architectural design field.

The BIM design is expected to expand to the domestic and overseas construction industries, depending on the effect of construction productivity and quality improvement. However, with the obligation of Public Procurement Service to design the BIM design, it includes a design error and the problem of utilization of 3D design by choosing a simple 2D to 3D remodelling method that can not be modelled in 3D modeling or use of the construction and maintenance phases. The results reviewed by BIM design results were largely underutilized and were not even performed with the verification of the error. In order to resolve this, one must develop the check system that secures the quality of BIM design and ensure that the reliability of BIM results are available. In this study, it is designed to develop a program that can automatically verify the design of the BIM design results such as violation of the rules of the BIM design, design flaws, and improve the usability of the BIM design. In particular, this programs were developed not only to identify programmes that were not commercially available, but also to validate drawings in low-light computer environments. The developed program(LH-BIM) store the information of attribute extracted from the Revit file(ArchiCAD, IFC file included) in the integrated DB. This provides the ability to freely lookup the features and properties of drawings delivered exclusively by the LH-BIM Program without using the Revit tools. By doing so, it was possible to resolve the difficulties of using traditional commercial programs and to ensure that they operate only with traditional PC performance. Further, the results of the various BIM software can be readily validated, which can be solved the conversion process error of IFC in the case of SMC. Additionally, the developed program has the ability to automatically check the error and design criteria of the drawings, as well as the ability to calculate the area estimation. These functions allow businesses to apply simple and easy tasks to operate tasks of BIM modelling. The developed system(LH-BIM) carried out a verification test by reviewing the review of the BIM Design model of the Korea Land & Housing Corporation. It is hoped that the verification system will not only be able to achieve the Quality of BIM design, but also contribute to the expansion of BIM and future construction BIM.

The purpose of this study is to propose an curriculum for architectural studio in university to implement BIM process, through the analysis of the advantages of the BIM tool. The limitation of this study was to analyze the case study of only half year a single university. University education in the design process, the design that can be used in applying BIM content should be universal, university education considering the special working conditions, excessive BIM-based application can be difficult. Therefore, a systematic and reliable design that can be applied to education applies BIM design process is necessary to establish. University education applying BIM design review and design proposal the various 3D visualization can be used effectively to determine. In addition, the planned representation for thinking about and drawing 3D model building, architectural space can be used for visualization, and other subjects in conjunction with structural analysis, environmental analysis, facility layout, etc. can be used.
