중국건설업에서는 BIM (Building Information Modeling)의 활용을 통해 건설업의 비효율적인 상호운용성의 문제를 해결하여 건설업의 총생산액 증가시키고자 한다. 하지만 중국 주건부에서 2011년부터 건설업의 BIM활용을 촉진하였음에도 불구하고 중국에서는 BIM 활용률은 45% 미만인 것으로 나타났다. 한편 한국 건설업은 중국보다 먼저 BIM 도입을 하여 활용하고 있는 만큼, BIM 활용수준과 BIM 수용의지가 중국보다 높을 것으로 예상된다. 따라서 본 연구에서는 한국과 중국의 BIM수용영향요인 비교분석을 통해 중국의 BIM 활용률을 향상시킬 수 있는 방안을 제안하고자 한다. 한국과 중국의 BIM수용영향요인 비교분석을 위해 기술수용이론(Technology Acceptance Model; TAM)과 BIM 수용모델 관련 선행연구고찰을 통해 BIM 수용영향요인을 분류하고, 중국의 국가적 특성과 중국건설업만이 가진 특성을 반영한 BIM 수용영향요인을 추가하여 실제 BIM 사용자인 한국과 중국 건설사업 참여주체(시공사, 설계사, CM)를 대상으로 설문조사를 실시하였으며, 통계값을 유의미한 차이를 알아보기 위해 SPSS 22.00을 활용하여 t-test 실시하였다. 마지막으로 t-test 결과를 기반으로 중국의 BIM 활용률을 향상시킬 수 있는 개선방안을 제안하였다. 본 연구의 결과를 통해 중국 건설업에 적합한 BIM 활용 활성화 방향을 제시하고, 중국 건설업의 BIM 활용 활성화 연구의 이론적 기초를 제공할 수 있을 것으로 기대한다. In the Chinese construction industry, the utilization of Building Information Modeling (BIM) aims to increase the total output of the construction industry by solving the problem of inefficient interoperability in the construction industry. In 2011, the Chinese Ministry of Housing and Urban-Rural Development despite the technical advantages of BIM and the government policy, the BIM adoption rate in China is lower than 45%. Meanwhile, as the South Korean construction industry is a step ahead of its Chinese counterpart in introducing and utilizing BIM, it is expected that BIM is more actively utilized and accepted in South Korea than in China. According to a comparative study based on the hype-cycle theory, South Korea is at a more advanced stage of introducing BIM, than in China. This study aimed to suggest how to increase BIM utilization rates in China. To this end, this study comparatively analyzed factors affecting BIM acceptance between China and South Korea. For the comparative analysis of the BIM acceptance factors between China and South Korea, literature reviews on the technology acceptance model (TAM) and BIM acceptance model were carried out, and based on that, the BIM acceptance factors were classified. Other BIM acceptance factors were also added and considered, as they reflected Chinese national characteristics and construction industry. As for the derived BIM acceptance factors, construction project participants, especially actual BIM users in China and South Korea, were targeted for the survey. A t-test using SPSS 22.00 was carried out to identify significant differences in data. Finally, based on the t-test results, this study suggested ways of improving the BIM utilization rate in China. Based on the findings, this study is expected to contribute to activating BIM adoption in the Chinese construction industry and also to set a theoretical foundation for future studies on BIM utilization in the industry.

송경욱,이석주,유창균,조용준 朝鮮大學校 建設技術硏究所 1999 建設技術硏究 Vol.19 No.3

The city is the social space with a lot of people having the various and different background and positions. That the city is the social space of high density means it is the space for convenient and comfortable life with the sense of community in frequent activities by overcrowded people and for this, intentional human behaviors within the city. From such a viewpoint, this research is to examine and analyze the publicity of external space of buildings with open space which is the important factor in improving the quality of city and the results of the research are as follows. It is found that the installation of open space has been made at the place where urban development is actively performed from the center of city with many users, but the open space which secures the comfort of the city and then attracts the people is not secured and is in the stage of legal restriction and the conversion of building owner's consciousness is needed. It is analyzed that most of open space are located at the front, but in fact there is no device which intercepts the eyes of pedestrian and open space users and since each space is divided by merely ground border, it is difficult to find the hierarchy or territory of two spaces and more considerations should be given for users. It is shown that the obligatory installations of open space such as bench are not equipped. Since the open space in urban area should be prepared in the side of publicity for users as well as for the urban comport, it is considered that the conversion of building owner's consciousness and institutional supports like incentive system should be followed. Moreover, open space have an influence on the diversification of architectural design, architects must consider the diversification of location, form and components of open space to make it an attractive space for users.

송경욱 ( Song Jingxu ),유정호 ( Yu Jung-ho ) 한국건축시공학회 2021 한국건축시공학회 학술발표대회 논문집 Vol.21 No.1

Since the first BIM development outline was issued in 2011, China has initially tried to adopt BIM in the construction industry. After the BIM guide was issued in 2017, China has officially entered the era of building informatization in the construction industry. Through the statistical data of BIM application reports in China's construction industry from 2014 to 2020, this paper concludes that China has made great progress in the popularization rate of BIM, but has little effect in the adoption in actual projects. Through the reading and analysis of relevant documents in China, 13 obstacle factors for BIM technology adoption in construction enterprises are preliminarily defined.

이슬기(Lee, Seul-Ki),송경욱(Song, Jingxu),유정호(Yu, Jung-Ho) 대한건축학회 2021 대한건축학회논문집 Vol.37 No.11

Both Korea and China have designated BIM application compulsory targets to revitalize BIM in the construction industry and established a BIM revitalization promotion plan. In order to obtain the expected effect of using BIM, it is necessary not only to purchase tools for BIM use and to prepare related systems and organizations, but also to identify and reflect user requirements through periodic performance evaluation from the users point of view. Therefore, this study examines the strategies established for BIM activation in Korea and China, evaluates each countrys BIM utilization performance, checks the investment direction for each countrys BIM activation, and derives key improvement factors and improvement plans. The importance and performance of the expected effects of BIM are measured on a 7-point scale for construction industry practitioners in Korea and China who have experience in using BIM. We verify whether there is a significant difference in the importance and performance using t-test and derive priority improvement priorities for each country using IPA. According to the results of the analysis, in Korea, the effects of high importance were also high in performance. This is judged to be the result of relatively long-term investment based on a specific implementation plan for revitalizing BIM. On the other hand, unlike Korea, China does not show a specific trend, and ‘Maintain relations with the client’ has the highest performance in both the design and construction stages. It is judged that China is greatly influenced by external factors in the use of BIM. Through this, it is meaningful not only to identify improvement plans for each country, but also to suggest the necessity of establishing a specific implementation plan while presenting the characteristics of BIM utilization by adoption time.
