최근 우리나라뿐만 아니라 전 세계적으로 고층건물의 규모가 점점 커짐에 따라 고층 건물은 초기단계에서부터 막대한 자원과 비용이 발생하고 도중에 설계변경이 어렵거나 불가능한 경우가 많아졌다. 때문에 초기구조설계과정과 실시설계, 시공과정에서의 차이를 최대한 줄이는 것이 사업의 경제성을 좌우할 만큼 중요한 비중을 차지한다. 이러한 정보를 제대로 관리할 초고층 BIM 정보환경이 구축된다면 발주자 설계자 시공자가 얻게 될 이익은 결코 적지 않을 것이다. S-BIM 프로세스 상에서 철골조를 형성하기 위해서는 세 단계의 프로세스를 거치는데 구조 해석 및 설계 단계, 구조 해석 및 설계 결과 데이터베이스 구축, 철골구조설계 및 형상화 모듈에 의한 부재 생성이다. 본 연구에서는 구조해석 및 설계(Analysis and Design, A&D) 데이터베이스를 C#코딩을 통해 형상, 길이 및 위치 정보를 결정하는 데 필요한 정보를 모듈 상에 불러오고, 이를 이용한 부재의 치수, 길이, 좌표 값을 산정하였다. 모듈 결과 생성된 정보를 BIM 플랫폼 상에 모델링함으로써 사용자 입력 값을 최소로 하여 기존 BIM 플랫폼의 모델링 방법 대비, 생산성이 향상된 철골구조설계의 자동화를 구현해 보고자 하였다.

A conventional Design for Safety (DfS), introduced to eliminate potential hazards in the design phase proactively, has encountered persistent challenges, such as perfunctory risk assessments and hazard identifications based on 2D drawings and inefficient workflow processes. This study proposes a BIM-based approach to Design for Safety (DfS) to address the limitations of conventional methods, aiming to enhance efficiency and achieve practical safety management benefits. The proposed workflow process for BIM-based DfS has been refined and validated for on-site applicability through various case studies, including risk assessments during the design phase and field applications for safety management activities during the construction phase. Specifically, the critical process of risk assessment within the DfS methodology has also been transitioned to a BIM-based approach. This BIM-based risk assessment process has been evaluated through case studies, encompassing safety reviews for structural design, construction equipment operation, and construction methodology with sequence in design projects. Additionally, the proposed BIM-based DfS has demonstrated exceptional on-site applicability and efficiency, as validated by the application of a BIM deliverable embedded in DfS information for CDE-based daily activity briefing, VR-based safety training, AR-based mitigation measures inspections, and other safety management activities in the construction phase.

Recently, there have been various attempts for the adoption and spread of Building Information Modeling (BIM) in the construction industry. However, the spread of BIM has been less satisfied than expected, because of the insufficient, expensive hardware and software for the authoring, analysis and so forth. As a solution to resolve the obstacles, the applications of cloud computing technology to BIM have been introduced. Due to the vendor-dependent functions and lack of verification on the work process, the spread of cloud-based BIM has been limited in Korea. Therefore, this study proposes the functions of cloud computing services which can support BIM-based design processes through the review of practitioners, questionnaire survey and analysis of design process.

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.

In this paper, we propose a novel method for converting the existing 2D processes in the design and construction phase of civil engineering, to the future BIM-based processes. First, we compare and analyze the actual application processes of the outputs of the existing 2D method and the outputs of the 3D BIM method, for the whole process of BIM design of earthworks and road structures and integrated utilization of quantity, process(4D) and construction cost(5D), in view of life-cycle. The proposed method acquire the outputs of the design phase integrating IFC international common standard file information and CBS/OBS/WBS standard classification scheme information, and acquire the outputs of the construction stage by using an integrated utilization module for quantity, process(4D) and construction cost(5D). Ultimately, we intend to commercialize the step by step technologies for BIM design and construction in civil engineering by using the proposed method.

In order to meet the needs of integrated design process in architect industry, BIM(Building Information Modeling) education in university is urgently needed. However, the investigation of the current status of BIM education at 60 universities shows that most universities do not offer BIM education at all, or opened only one regular course for BIM education. The survey on BIM education for students shows that non-curricular activities brought bigger educational achievements than regular courses. Considering these findings and the practical restrictions of the universities, and through evaluation and feedback from professors as educational providers and working architects as professional users, the desirable strategy for BIM education in architect design was able to be suggested, which is consisted of regular curriculum of two courses and 40 hours non-curricular activities.

Many studies on BIM-based design, construction and operation have already been conducted on roads, railways, etc., but BIM research in the ports and harbors is still lacking. This research develops BIM Library and Technical contents focused on practical usability of ports and harbors infrastructure. We have developed technical content by applying various User Interfaces and workflows, considering the characteristics of ports and harbors design. In order to examine the practical utility of the developed library and contents, we tried modeling the breakwater using these. As a result, we confirmed that collaboration of BIM library and technical contents could significantly improve the productivity of BIM design by increasing library usage and automating repetitive tasks.

The purpose of this study is to demonstrate the improvement of the education process in architectural engineering through the analysis of the advantages of the BIM tool. As public institutions and owners have been introduced to Building Information Modeling (BIM) tools, BIM has become an important factor in the design process in undergraduate university programs. First, BIM-related issues, domestic and overseas, was analyzed. Second, a case study of BIM education was analyzed at K University under the ABEEK process. Students participated a survey about the understanding of BIM and the use of BIM tools. As a result of the analysis, six advantages of the use of BIM tools were found. As a result of this research, following five issues are found about BIM education through advantage of using BIM tools. The result of this research was verified by conducting a survey on the usage of BIM softwares. The limitation of this study was to analyze the case study of only limited numbers of participants at the university.

As the amount of information generated in the construction project increases exponentially, design and construction review have a serious impact on the success of the site. For this reason, academic and business circles have been expanding the use of BIM at the whole life, and BIM is now accepted as one of the standards used in the construction industry. However, the BIM-based design for the temporary work is used as an aid to the 2D design because there is no specialized software and there is absolutely lack of a professional engineer. The objective of this research is to develop BIM-based temporary work support system. This system minimizes human errors in BIM-based design, quantity takeoff and inspection and shortens working hours.

This paper aims to analyze design errors prevented by building information modeling (BIM)-based design validation to identify consideration factors for successfully implementing BIM-based design validation in the architecture, engineering, and construction (AEC) projects. More than 1,300 design errors detected by BIM-based design validation in three BIM-based projects in South Korea are categorized according to its causes, work types, and likelihoods to cause project delay and cost overrun. Each design error is analyzed by conducting face-to-face interviews with practitioners in the three projects.
