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.

코로나19 이후 건축사업계 비대면 작업 등의 필요성이 대두되면서, 스마트건설 플랫폼 기술인 BIM(Building Information Modeling, 건설정보모델링) 활성화에 관한 목소리도 높아지고 있다. 최근 한국건설기술연구원에서는 공공분야 BIM 기술의 성숙도를 4단계(레벨1~4)로 봤을 때, 우리나라의 평가치는 '레벨1' 초보 수준에 머물러 있다는 진단을 냈다. 이미 '레벨3' 수준에 진입한 영국 등 선진국보다 뒤처져 있다는 분석인데, 이는 2D 환경을 기반으로 설계 또는 시공업무에 대해 제한적으로 BIM을 적용하면서, 일정 규모 이상의 설계BIM만 의무화한 수준이기 때문이다. BIM 트렌드가 '기술개발'에서 '활용' 단계로 넘어가는 과정 가운데 건축분야에서의 활성화 방안은 무엇일까. 월간 '건축사'가 'WBIM(주.더블유빔)'사(社)의 이재환 대표를 만나 BIM의 현장 활용성, 그리고 적용 측면에서의 현실문제 등에 대한 현장 이야기를 들어봤다. 각종 개발사업과 설계파트를 지원하며 BIM전문가로 활동해 온 이재환 대표는 "기획단계부터 BIM을 활용하면 사업 진행 전 과정에서 실시간 검증이 가능하고 동시에 각종 아이디어를 효과적으로 적용할 수 있다"면서도 "활용성을 확보하려면 업계뿐 아니라 발주처, 감독 등도 BIM에 대한 이해도를 높여야 한다"고 말했다.

Recently, BIM has been actively adopted in construction projects and industries, and also integrated with Information and Communications Technology(ICT) such as cloud computing technology, sensor technology, 3D scanning and printing technology etc. However, it is very difficult to efficiently utilize BIM services, technologies and collaborate with each other because of differences of usage and requirements of technologies. Every participant in the same construction project has their own needs, requirements and details of the model in each phase. In order to enhance utilization BIM model, BIM services and technologies required in their project have to be clearly defined in the initial stage of the project. In order to support the owner to define the BIM level, BIM service level and application technologies are identified and guidelines how to define the level and technologies for their project purpose are suggested in this study.

본 논문에서는 최근에 개발되어 지하철 919공구에 적용된 BIM 기반 통합 공사관리 시스템의 구축방법과 적용성에 대해 검토하였다. 최근 대형 국책사업이 발주, 시공되면서 효율적인 공사관리를 위한 PMIS 도입이 보다 활발해지고 있는 가운데, 기존의 텍스트와 그래프 위주에서 BIM(Building Information Modeling) 기법의 하나인 4D, 5D 시스템을 이용한 다양한 시도가 되고 있다. 한편, BIM은 건설 전 생애주기에 걸쳐 활용되어야 그 도입목적을 극대화할수 있으나, 현 단계에서는 계획 및 설계단계에만 초점이 맞춰져 있어 실제 공사중에는 그 활용도가 상당히 낮은 수준이었다. BIM 기반의 통합 공사관리 시스템은 공사중, 현장과 본사를 비롯해 발주처와 감리단 등 다수의 공사 주체들이 계획, 설계시 구축된 BIM을 보다 효과적으로 사용하도록 함으로써, BIM의 공사중 활용성을 높일 뿐 아니라 유지관리 단계까지 확장하여 이용될 수 있다. 본 논문에서는 BIM 기반 통합 공사관리 시스템을 구축하기 위한 절차를 살펴보고, 최종 구축된 통합시스템의 적용성 분석후 활용방안을 제시하였다.

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.

Most current BIM systems are focused on the visual information of work status in the design and construction stages. In a passive BIM system, 3D CAD tool can visualize the interference elements of design drawings, however, it cannot suggest a solution to solve the interference status. And 4D CAD tool in the construction stage can simulate the appearance of each activity by construction schedule, however, it cannot suggest an optimized schedule plan considering specified schedule condition of the project. Recently, many organizations need BIM solutions that can improve the work status beyond the level of simple visual information from BIM system. Active BIM system can provide the solutions to the project manager. This study suggests active BIM functions for the solutions and attempts to develop a 4D CAD engine to validate the usability of the functions.

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.

Recently, both nationally and internationally, various BIM guidelines have been developed. These guidelines present fundamental principles and standards for the application of BIM. However, practical BIM guidelines for the schedule management area in the construction phase are lacking, making it difficult to apply them effectively in practical work settings. In this study, performance-based delivery guidelines are presented for the key functionalities of 4D CAD systems, which are representative BIM tools used in the construction phase. To achieve this, a survey analysis was conducted to determine the prioritization of these functionalities. Based on the characteristics of the project, delivery guidelines were formulated to allow users to selectively utilize the guidelines at different levels. Furthermore, practical ways to utilize performance-based delivery guidelines for schedule management using 4D CAD were proposed, validating the usability of these guidelines. The research findings suggest that these guidelines for BIM functionality in schedule management can hold practical significance as the utilization of BIM in construction phases continues to increase.

In recent years, BIM services have been used in many construction projects. However, they are raising the question that there are many differences between what was initially proposed and what was actually done. In the IT sector, a method called as SLA is used to perform an assessment of the services delivered to the IT service project. In this respect, this study intends to introduce this method into building construction projects to use BIM in order to propose evaluation criteria and the evaluation process for SLA-based BIM service. The BIM service assessment process and criteria presented are judged to help introduce consistent and systematic BIM services in construction projects.
