Recently, the adoption of BIM technology in domestic civil engineering projects has continually increased both in its numbers and scope. However, the BIM model was developed and used after the 2D design was developed instead of creating the BIM model from the conceptual design phase. BIM must be used throughout every phase of design and construction to use BIM for its original purpose. However, if BIM application is applied in heavy civil projects without a step-by-step guideline, it can confuse the market and face industry resistance to using BIM. Therefore, BIM is currently being used step by step in the civil engineering field by using BIM as a conversion design. However, the BIM conversion design method, currently being performed in the Preliminary design stage, has many difficulties due to low work efficiency. This paper analyzes the existing process of converting a 2D design into a 3D BIM model while addressing the issues related to its low work efficiency. To this end, a novel approach to 2D to BIM conversion for the design development stage is proposed.

Building information modeling (BIM) is a smart construction technique that is recognized as essential for current construction facility projects. The Public Procurement Service (a construction project-ordering agency) announced a plan to introduce BIM and has required changing the operation of projects by using BIM design information. LCC analysis is essential for items, quantity, and cost information of the construction, and it is expected that efficient work will be achieved by using BIM design information. In this study, a BIM-LCC analysis system was established for selecting optimal design alternatives by actively using open KBIMS libraries. The BIM-LCC analysis system consists of a single alternative and an optimal alternative LCC analysis, but it has a limitation in that only the architecture and machine libraries have been applied. However, by applying BIM, practical use and work efficiency can be expected. In order to use the method as an LCC analysis support tool with BIM design information in the future, it will be necessary to collect user opinions and improve the UI.

Public institutions and owners have been introduced to Building Information Modeling (BIM) tools. BIM has become an important factor in the design process in undergrad programs. The purpose of this study is to demonstrate the improvement of the architectural engineering design process through an analysis of BIM courses. BIM education courses are analyzed to compare the level of detail in BIM education. An architectural engineering design class needs to involve BIM in the introduction of an integrated design process. An architectural engineering design process needs to be based on understanding design, building structures, construction and building services. 3D Modeling helps support an understanding of building structure and eco-friendly element analysis. The new process of architectural engineering design education is proposed as a result of this research.

Small and middle sized architectural design firms still have trouble using BIM (Building Information Modeling) for their tasks, which means that it is necessary to develop BIM Libraries and Technical contents. These BIM libraries should be based on common technical standards that reflect the technical contents to provide optimum BIM design support. This is essential to reduce the technological burden on the design office, because BIM does not just involve the 3D modeling of the design, but provides very important information for calculating the quantity of materials required for the construction and providing materials for the design work. Therefore, this research was aimed at improving the efficiency of the BIM design process by developing a system module based on the BIM technical contents data for the purpose of linking the BIM data and technical contents. The developed system module will be expanded to other uses of BIM in the long term.

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.

BIM (Building Information Model) and GIS (Geographic Information System) are applied widely to all stages (Planning - Design - Building - Maintenance) of construction. Recently, research for designing an integrated BIM/GIS platform has been conducted to determine the synergy effects. This paper reports the derivation of BIM/GIS platform application scenarios and definition of specific functions in construction planning and design phases. First, BIM/GIS application scenarios and platform functions are derived for each phase based on an analysis of business affairs. Second, SW functions, which compose platform function, are defined. In the construction planning phase, location selection and route location business affairs were analyzed. Preliminary design and detailed design business affairs were analyzed in the construction design phase. The result of this research can be used for BIM/GIS integrated platform design in the future.

In domestic construction industry, there is lack of the communication between planning, design, construction and maintenance. This problem makes the omission of information and the loss of cost. Therefore, the introduction of BIM can be a solution about that. BIM manages all information generated during all life-cycle of a structure and consequently maximizes the efficiency of utilizing information. This is done through 3D information model associated with a three-dimensional(3D) parametric CAD. This study proposes the design process of steel box bridge for structural design work of bridge construction project based on BIM. This process has 3D modeling progress done by using the information decided in design phase. When the subject for the proposed process is superstructure of steel box bridge in construction, the structural calculation sheet can be derived with the structural design process based on BIM.

Purpose: There is not much time left for mandatory BIM implementation for all sectors and stages of the construction industry. Therefore, it is necessary to find a way to secure technology to substantially improve the productivity of BIM work. In the research, we proposed a method to automatically verify related construction standards for major objects produced by BIM modeling procedures so that engineers can verify construction standards in the BIM-based design process. Method: We defined a modeling work procedure for BIM-based road design work and prepared a method for constructing related design standards in a database. In addition, a process map for developing a BIM-based design basis review automation system was also presented. Result: A BIM-based design standard review automation module was developed using Civil3D and Dynamo. And it was confirmed by the test application that it is possible to quickly judge whether the BIM object manufactured in the design process conforms to the construction design standard. Conclusion: BIM-based design standard review automation technology can improve the productivity of BIM model production work and secure the quality of the BIM model.

Building information modeling (BIM) has the advantage of having been utilized for various scenarios through a single model. Although extracting 2D drawings from BIM is one of the advantages, there are many difficulties when utilized in practical work. Architectural detail drawings are an important factor for expressing interior finishing materials and complicated construction methods, as well as for cost estimations. However, creating detail drawings does not have a standard, and each design company establishes its own detail drawings, so it is hard to share or exchange information in the construction industry. Therefore, this study suggests a systemized method for making detail drawings, and explains how it can be utilized as back data for quantity take-off and construction expenses linked with BIM libraries.
