The introduction of BIM-based project has increased in the domestic recently. Therefore the demand of BIM professionals is surging combined with the necessity of BIM education. However BIM education done in the domestic industry and public organization is only focusing on the 3D modeling, As a result an educatee could not put the real intention of BIM into practice. Thus through this study the wrong recognition of BIM will be corrected and this study analyzes the problems of domestic BIM-based project. This study examines the improvement of domestic BIM education cases by drawing the capability of BIM professionals.

BIM is effective to improve the labor productivity of construction participants. From this point of view, it is important to analyze the outcome related with BIM Labor which covers most of the BIM investment costs. This research focuses on BIM RFI which is one of the major task of the BIM labor and analyze the outcomes. In addition, this research was quantitatively analyzed by the standby time and related cost caused by BIM labor, which affect the results of the project participants. To this end, analytical standby queue model was utilized to analyze the labor focusing on micros TASK. 11 projects were selected to analyze the results of BIM labor and RFI that the project participants requested to the BIM labor was collected. Through this, it collected variables for analyzing results, and Finally, we pulled out 4 projects for analysis. In this study, the basic results analysis of RFI processing of the BIM labor, the probabilistic analysis of BIM labor service status, and the economic analysis of BIM labor optimal inputs were performed by using the research model presented. The results of this study can be utilized to formulate the optimal strategy for BIM labor inputs(e.g. number of employees, level, time point, etc.) of the construction phase. Moreover, it can contribute to ensuring the credibility of the BIM ROI results by presenting the cost of BIM services in BIM ROI analysis and the standby cost of project participants.

Architectural firms that would like to adopt the BIM are currently in an unfavorable position because of reduced orders, polarization of orders, and low price design. This study was conducted to evaluate plausible methods for supporting introduction of BIM into small sized firms. Before suggesting plans for support, we analyzed support projects and laws relating to support for small sized firms, after which we conducted a survey of small sized firms that support the project. The survey was completed by 242 architects and consisted of questions regarding the following aspects: current status and problems associated with BIM utilization, preference of certain policies for BIM introduction support, and reasonable level of support. After the survey, it was concluded that architectural firms are willing to use BIM and agree with the need for financial support for BIM program purchase and education, as well as to support BIM experts and fund low interest loans. In conclusion, it is proposed that support plans for small sized architectural firms in the areas of BIM introduction consulting, financial funding for the introductory process, provision of education and experts, order support, and promotions for accomplishment be provided.

현재 우리나라 건설 사업에는 BIM의 관심과 사용이 급증하고 있다. BIM의 현주소는 실무에 적용하기 어려운 단점이 많고 IFC를 이용한 정보호환에 어려움이 많다. 결과적으로 Architectural BIM Tool에서 모델링한 프로젝트를 Structural BIM Tool에서 다시 모델링을 하고 MEP단계에서도 다시 한 번 더 BIM 모델링을 하는 반복 작업과 반복 작업으로 인한 인력손실과 프로그램간의 유통과 호환에 문제가 많은 것이 현 실정이다. 이에 본 연구는 타 분야와의 정보 공유를 설계단계에 따라 상세 수준별로 분류하여 설계/설비 분야와 정보를 공유하고 물리적 모델과 해석적 모델의 상이로 인하여 현 정보 교류에 많은 문제점이 있어 두 모델간의 정보변환을 위한 알고리즘을 개발하고 구현하였다.

Recently, foreign construction companies through the BIM-design have the effect of improving productivity and quality construction. On the other hand, domestic BIM-design is a little depressed because of lack of additional costs and professional personnel problem. The construction industry of recession, as reasons of construction market is downsizing. First must, enabling the design in public institutions, mainly BIM.. Design for BIM the construction sector, as well as an early stage actively introducing and spreading of the performance of him and domestic BIM technology should be able to promote the development. Public institutions in accordance with this study presented measures that can stimulate the BIM design on LH. To that end, the public agency's design were analyzed, and suggested the Improvement and Application of the four aspects for Modular Coordination BIM Design. Also, gradually formulate a "road map for public institutions applied design bim" in order to carry out the plans put forward and presented the expected effect of him. The proposed work was public institutions will be used as a pilot project in Korea Land Housing Corporation.

The several smart construction technologies are being introduced to the construction industry, and among these technologies, a few companies are attempting quality control using 3D scanning and BIM. Therefore, in this study, 3D scanning and BIM were applied to cases of on-site quality inspection to confirm the applicability and utility. As a result, it was confirmed that the quality inspection using 3D scanning and BIM was shorter in time than the previously performed quality inspection and can be realized with less manpower. Therefore, it is considered that 3D scanning and BIM-enabled technologies can be applied to various items of quality inspection.

In recent years, the use of BIM in domestic construction has been increasing, but it is used mainly for internal and external visualization rather than for BIM design including drawings. For this reason, several studies have highlighted the lack of libraries and economic problems for BIM design. In other words, for the most economically small domestic design offices, activating the BIM design is a negative factor because it is difficult to invest the necessary manpower and cost to produce and use the required BIM library. The BIM design can be more applicable if the library can be supplied economically, easily, and quickly. In this study, BIM library business model and consideration factors that can provide BIM library service economically, easily, and quickly by considering the existing building material selection task and BIM library are presented. The proposed business model will increase the number of suppliers of BIM libraries, which are lacking in Korea, and will enable an effective BIM design at low cost and effort. If a service that reflects the business model proposed in this study is made, an integrated database that can consistently share information in the design, construction, and maintenance stages will be constructed. This can monitor the changes in material and equipment information during the life cycle of the building. The database can be used to monitor any changes in material and equipment information throughout the life cycle of a building, so that it can be used as historical data for effective design and maintenance as well as for material and equipment upgrades.

Recently, as smart construction has become more active, construction companys are evaluating their smart construction capabilities in order to transform into smart construction companies. However, the revitalization of smart construction doesn't only apply to construction companies, the level of utilization of all participants, including owners, designers, construction project managers, and construction company, must be improved. Therefore, this study aims to present a model that evaluate the building information modeling (BIM) utilization level for measuring the BIM utilization level of construction management companies in executing construction project management. In this study, an AHP questionnaire survey targeting BIM practitioners to calculate the weight of each BIM utilization item and score it to construct evaluation model and evaluate it by applying it to construction management companies are conducted. As a result of the evaluation using model, there were differences between companies in the number of BIM users, and in the qualitative evaluation, it is mainly used for interference review, constructability review, and design change management. Therefore, in order to revitalize BIM, it is believed that it is necessary to strengthen BIM utilization ability through separate training for construction manager (CMr) and to present clear utilization standards and scope of work for BIM utilization in performing construction management tasks. Consequently, evaluating more construction management companies using the model presented in this study will result in the transition of CM companies to smart construction and revitalization of BIM adoption.
