BIM 전기설계는 조달청 공고에 따라 공공부문에서 의무 적용을 시작하면 민간까지 점차 활성화 될 것으로 보이지만 기술적인 부분이 뒷받침이 되어야 조기정착 뿐만 아니라 관련분야 시장경제 활성화를 도모할 수 있을 것으로 예상된다. 하지만, BIM 활용가이드, 프로그램 등 활용상의 기술적인 부분이 개발되어 있지 않아 현실적인 어려움에 처해 있는 것이 사실이지만 이보다 더 시급한 것이 실무자들이 활용할 수 있는 기반을 마련해 주는 것이 더 시급하다. 그 일례로 BIM 설계에 필수요소인 라이브러리를 활용하고 공유하기 위한 기본체제인 라이브러리 표준화가 가장 시급한 것으로 보인다. 이에 본 논문에서는 BIM을 국내 전기설계시장에 조기 정착시켜 모든 용역에 대해 BIM을 적용할 수 있는 방안으로써 라이브러리의 표준화 방안에 대해 살펴보고자 한다.

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.

The importance of using construction data is increasing in accordance with the recent trend in the smart construction. However, construction project and maintenance information is distributed on the web, and the existing BIM(Building Information Modeling) information exchange and linking method using IFC(Industry Foundation Classes) cannot support connection with BIM data and web resources. This study aims to establish the BIM-based port facility data integration system using linked data(LD) technology in order to integrate BIM and heterogeneous data in the port maintenance domain. To this end, the port BIM-based ifcOWL and port facility maintenance ontology were designed, and LD was built for the BIM and maintenance information of Busan New Port 2-1 Pier3, a BIM pilot project. In addition, service prototypes such as search, statistics and SPARQL(SPARQL Protocol and RDF Query Language) endpoint functions were implemented using the issued LD. The LD-based information utilization system is expected to improve the reusability of information by converting the existing closed information system into an open system and BIM and maintenance data as a web resource in a standard format.

Recently, the utilization of the BIM system has been extended to cost and resource simulation, visualized management of construction site information and application of augmented reality including basic 3D modeling. Therefore, various BIM functions are being developed for practical applications. However, since clear classification criteria and knowledge information of BIM functions are not sufficient for field engineers, it is difficult to identify the necessary BIM functions for a construction project. This study suggests a BIM function breakdown structure considering the individual functional properties and a process model that can be ordered by applying BIM in a railway construction project. The proposed delivery model is used to obtain a practical utilization of BIM by analyzing features applicable to railway construction projects; model is verified using a case project.

Recently, Korean Traditional House is being reconsidered as a alternative and eco-friendly residential housing. With these flows, government and industry actively studies the modernization and industrialization of Korean Traditional House. Apply for BIM as a way of modernization and industrialization of Korean Traditional House, research has been actively conducted. Korean Traditional House is building that is assembled by individual Component Therefore it is very useful for modernization of the Korean Traditional House to design Korean Traditional House With BIM. Which is the management technology that produces and distributes information of the architecture. But compared with the effect, the use of BIM is sluggish in the construction. Therefore, In this study after surveying about lowly using BIM on point of AEC(Architect-Engineer-Contract), the result is analyzed with AHP(Analytic Hierarchy Process). So the aim of this study is to offer the base to find the solution of the Affecting factors about lowly using BIM.

최근 건설 산업에서 BIM이 각광 받으면서, BIM 기반의 다양한 엔지니어링 기술 도입 및 프로세스 적용이 시도 되고 있다. 이중 BIM 기반의 프로젝트 운영을 위해서는 BIM의 데이터의 저장, 수정, 배포뿐만 아니라, 관련 주체간의 협업이 가능한 환경이 요구되고 있으며, 이러한 환경 구축을 위해 제조업에서 활용되고 있는 PDM(Project Data Management) 또는 PLM (Product Life-cycle Management) 시스템을 벤치마킹한 CPLM (Construction Project Life-cycle Management)과 같은 BIM 기반 협업 시스템이 등장하고 있다. 하지만 기존의 이러한 협업 시스템의 경우, 건설 프로젝트가 가지는 다양한 계약 방식, 관리 단계, 관련 정보의 체계 등에 대한 종합적 계획 없이 프로젝트의 각 참여 주체들의 기존 관리 방식을 도입함으로써, 당초 BIM 기술을 도입하여 달성하고자 하는 원활한 협업 환경을 구축하는데 한계를 가지고 있다. 따라서 본 연구에서는 최근 BIM 가이드라인의 도입 등에서 시도되고 있는 BIM Planning이라는 개념을 활용하여, BIM 기반 협업 시스템의 구축 이전에 BIM을 관리하기 위한 관리 구조, 방식, 데이터 체계 등을 효과적으로 계획하고, 이를 시스템에 반영시킴으로써 보다 효과적인 BIM 기반 협업 환경이 구축될 수 있는 체계를 제안하였다.

In spite of advantage by using BIM as quantity take-off, schedule control and clash check, absence of guidelines is a barrier to applying BIM to road domain. In this research, domestic and overseas cases of BIM guideline are analyzed in order to develop the road BIM deliverable submission system. The analysis is classified 5 topics which are BIM submit product list, submit files format, availability of existing 2D based products, BIM authoring tools and submit process. As a result, It needs a lot of effort to standardize BIM delivery system for road domain because BIM submit product list and BIM authoring tools are changable depending on BIM use cases. However, submit files format and submit process are common part to suggest guidelines of road BIM delivery system. It requires to combine BIM and 2D products for road BIM delivery system because delivery products are not exactly alternative 2D based delivery products for the present. The authors expect this research to use as basic data for development of the BIM deliverable submission system in road domain.

BIM is a rising core technology for increasing the productivity of the AEC industry, but such a paradigm shift is placing excessive demand on the practice of small medium size enterprises. BIM has many useful functions that are difficult to imagine in 2D CAD but BIM programs and the system buildup cost are too expensive. Therefore, small medium size enterprises hesitate to apply BIM in their fields. In this study, a customized 4D and 5D system was implemented using the building information generated from basic BIM tools, such as Revit, MS Project, Navisworks, and Excel VBA's customizing process to review the schedule and verify the quantities according to the schedule. Those programs are so basic in BIM circumstances, that small medium size enterprises can be equipped without burden. As a result, essential building information for 4D and 5D system implementation was investigated and its customizing process was established.

The construction progress control is very important because there are many unexpected factors affecting time schedule delay and cost overruns. A complicated measure including item quantity and inherent time and costs is used to monitor the progress. Another element to be considered is a productivity, which is cost effectiveness because productivity is primarily measured by the costs. Productivity is stated as constant in-place value divided by inputs such as worker-hour. The main purpose of this paper is to analyze the productivity of structural formwork using a 3D BIM. In order to achieve the research objective, an integrated model of a BIM with a daily foreman's report is developed. The quantities being extracted from a 3D model and information are integrated with manpower utilized. The developed model is applied to a case project to measure and analyze the productivity in terms of individual building and work crew team. The results are discussed and further research topics will be addressed.
