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 Korea, recently, efforts have been made to introduce BIM(Building Information Modeling) to housing complex projects. However, there have been several problems including excessive competition for building design and outcome-oriented evaluation due to a lack of clear evaluation criteria and poorly organized management process. Under this circumstance, the study surveyed opinions of project managers and conducted a pilot test to improve evaluation criteria of BIM-based design for housing complexes. The objective is to assess the level of BIM technology and its applicability, and to propose a list of reasonable evaluation criteria for better project management. First, the study examined the current condition of evaluation on the BIM-based housing complexes, and identified 15 preliminary items that might be suitable for application of BIM. Second, the study conducted a pilot test for the 15 items to determine their suitability for the level of BIM technology, clarity of the calculation process, and the extent of fulfilling information quality, and short-listed eight items for application of BIM. In particular, in the design concept stage, mostly 3D visual images and area-related items are suitable for BIM-based evaluation. Accordingly, formerly used items such as project cost, energy and environmental analysis, building structure, and facilities were deemed more relevant to the subsequent stages of basic design and its implementation.

Building information modeling (BIM) can improve to communicate with project participants by early construction involvement (ECI) from the beginning of the project. Therefore, they can minimize design changes and improve design quality and construction. However, because there is insufficient research on the scope and application level of BIM according to project delivery system and project characteristics, construction companies have efficiently not been using the BIM. Therefore, this study intends to conduct basic research as a basis for confirming appropriate BIM application and level according to project delivery system and project characteristics. To do this, we investigated the project delivery system and project characteristics of domestic and foreign projects that have successfully applied BIM, and compare and analyze them based on BIM application and BIM level framework derived from theory reviews and experts. Therefore, this study can be used as a basis for strategically establishing the scope and level of BIM according to project delivery system and project characteristics through the result of this study.

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.

Building information modeling (BIM)-based construction projects have increased and become more varied, and as such the management of BIM-based facility information is also increasingly important for facility maintenance. Information management, and specifically product data mapping, however, has some problems in the area of manual data entry and does not adequately consider the exchange requirements of facility maintenance. Therefore, it is necessary to introduce a method to improve the management of composite object information for BIM-based facility maintenance so that it can handle construction operation building information exchange (COBie) data for a composite object. Therefore, we present a method to map COBie data to related materials of a composite object. This research contributes to increasing the efficiency and accuracy of the required information mapping between a building model and product data using a BIM library through optimal BIM data adoption. Moreover, it allows for the creation and management of specific product data at the design development phase.

Recently policy and clouding system to mandate the introduction of BIM in construction industry, various sensors technology, BIM in ICT technology and fusion, such as 3D scanning and printing technology has been further activated. However, the expression level of diversification associated with it, plan within one of the BIM project, design, engineering, it is difficult to have a different application has been consistent for each field, such as construction. Thus fell the efficiency of BIM apply, it is difficult to determine the appropriate level of BIM in the business early stage in order destination of position. In this study, in order to solve this problem, by utilizing SLA used in the IT field, it attempts to explore scheme which can be evaluated targeted level of BIM suitable for business in the planning phase.

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.

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.

The BIM techniques which manages information over the life cycle of construction project based on the 3-dimensional model are developing in the direction of integrated construction management including planning, design, analysis, estimation, 3D simulation and so on. The estimation model based on the BIM has different detail level and model information. In this study, the LOD of estimation model is catched for the bridge structures. The library classes are defined with construction information classification system, and the quantities of resources are calculated by class parameter using Microstation API. Finally, the automated estimation system using BIM based library is verified by the integrated model for adjustments of level of detail.
