This study conducted a survey for BIM experts as a basic study to improve the efficiency of a BIM-based review of the BF certification evaluation method. By limiting the buildings to elementary schools, the first survey was conducted to extract the mandatory facilities from the BF certification evaluation items according to the evaluation criteria, and 63 out of a total of 94 evaluation items were extracted. The extracted facilities were intermediary facilities, internal facilities, and sanitary facilities. The second survey provided detailed calculation criteria for BF certification evaluation items, and through investigating the possibility of BIM-based review, 31 items were derived. In the 3rd and final survey, when asked about the effectiveness of the current CAD-based and BIM-based evaluation methods, the BIM-based evaluation method showed 96.8% effectiveness and the CAD-based evaluation method showed 3.2% effectiveness.

This study aims to investigate basic requirements for adopting the Building Information Modeling(BIM) technology to management of civil infrastructures. The state of the art on BIM guidelines developed major countries was investigated, and a common framework of the guideline contents was built in order to categorize the requirements. In addition, it was investigated that the point of view on the facility management in the BIM guidelines showed different from the traditional civil infrastructure domain. On the basis of the investigation results, this paper proposed the core requirements categorized into three respects: development of application models, standardization, modification of regulations.

Recently, Discussion about BIM based LID (Low Impact Development) facilities management system is activated because interest of LID technique for urban water cycle restoration is increasing. For this reason, this paper developed the auto-checking module of the BIM (Building Information Model) based supply output table. This module will be the foundation of the BIM based LID facilities total management system. The research order is composed like next follows: (1) Select target area, (2) Make BIM model of LID facilities and extract supply output table, (3) Develop comparison module, (4) Analysis results. As a result, the authors made 27 LID facilities and developed the supply output table comparison automation module. So, the authors could find differences of 2D design documents based supply output table and BIm based supply output table. So, the authors made an improvement suggestion of the design plan and could construct foundation of the BIM based LID facilities total management system.

Current domestic and overseas BIM practice and research efforts show very few examples that design and construction BIM data could be successfully used for efficient operation and maintenance (O&M) of infrastructure in particular. This study takes public wastewater treatment plant requiring an enhancement of operation and maintenance capability into account to develop a prototype BIM-based maintenance management system. The system is designed and implemented following a typical system development procedure and validated by the system outputs per four scenarios being considered to be main maintenance activities: The research results are expected to contribute to the upgrade of current wastewater treatment plant maintenance level, which is more demanded as water-related regulation and policy direction changes to region-based large scale O&M and asset management adoption, and overseas market participation.

As the technology of Smart City and Digital Twin is developing, techniques to integrate BIM data of infrastructure facilities into GIS are becoming more critical. Hence, this study aims to manage BIM data representing bridge and tunnel structures through the Industry Foundation Classes (IFC) standard and to develop a method to link these IFC-compliant files to the GIS standard CityGML without loss of information. We analyze the criteria for creating BIM data for bridges and tunnels by reviewing the BIM guidelines set by each client. We use these criteria to suggest methods for data management based on InfraBIM as a specific IFC class standard. Furthermore, we perform model analysis to determine the necessary design and construction field-appropriate model process and Level of Detail (LOD). From the model analysis, we conclude that the classified BIM models can be used as base data to generate BIM models of bridges and tunnels for facility management.

현재 국내의 건설 산업은 BIM(Building Information Modeling)이라는 새로운 패러다임으로의 변화를 모색하고 있다. 이미 국내 건축업계에서는 적극적으로 BIM개념이 도입되고 있으며 주로 국가 기반시설의 건설업무를 분담하고 있는 토목업계에서는 현재 BIM개념을 도입하기 위한 준비과정에 있는 단계이다. 이 연구에서는 대표적인 토목구조물인 교량을 대상으로 BIM개념 도입의 필요성과 교량을 건설하기위한 여러단계 중에서도 그 출발점이라 할 수 있는 구조설계 단계에 있어서 BIM개념의 도입 방법과 기존의 구조설계 프로세스를 BIM기반의 구조설계 프로세스로 변화하기 위하여 필요한 작업들에 대한 분석을 수행하였으며 결과적으로 교량 프로젝트에 대하여 BIM기반의 구조설계를 위한 최적의 프로세스를 구축하기 위한 연구를 수행하였다.

The development of modern science and technology and computer engineering breakthroughs in the field of information and communication have brought about many changes in lifestyle. The government announced the goal of educational policy in 2030 to educate people in future society on a future-oriented perspective. Changes in the curriculum along with changes in educational facilities are essential. Therefore, the operation of a classroom should be associated with classroom spatial information. The BIM design based on 3D geometry information was designed. The BIM design can link the design information and non-geometric information of spatial information. This study examined the operation of school facilities based on classroom spatial information with BIM. This study suggests standardization of classroom spatial information based on BIM. The scenarios of BIM ordering and design for departmentalized classrooms management is proposed.

The re-locatable military facilities are significant in combat zones with limited infrastructures. Military tents are particularly one of the most essential components in the battlefields, During the offensive operation. This study assesses educational effectiveness of the 4D Building Information Modeling (BIM), which is used to deliver educational information with considering re-locatable military facility construction. Furthermore, the real time for constructing temporary concentration camp was measured, By using analysis of variance associated with the educational effects of the 4D BIM. Statistically, understandability of facility construction using 4D BIM was found to be higher than the conventional educational materials with field manual.

In the case of river facilities, the management of this information differs depending on national and regional rivers, therefore, there is no integrated management in place. There is concern about the loss of facility information owing to the insufficient accumulation of information during their design and construction stages. Additionally, as a result, the utilization level of facility information during the maintenance and operation stages is insufficient. To ensure effective maintenance and operation of river facilities, it is necessary to secure data consistency and increase efficiency by organizing facility information according to a standardized classification system. This study proposes a strategy for implementing the BIM standard classification system in the river sector, considering facility characteristics. The goal is to introduce a BIM information model for 3D-based river facilities, and enable efficient maintenance and operation conversion.

Extension IFC schema of subsidiary facilities were developed for the purpose of establishing an information model standard for roads. The IFC entities, types and properties for subsidiary facilities were defined through an analysis of the road design documents for the extraction physical component and design information. The converter and viewer for applying the new schema were then developed. Subsidiary facilities BIM models were converted to new IFC models to verify the research results. Standard BIM-based delivery and verification systems are enabled by using a standard model converted by new schema. Furthermore, it can establish an open BIM environment using an IFC over the entire life cycle of the civil engineering project.
