지난 호에 실린 첫 번째 연재에서는 BIM 개념과 동향 그리고 사례 및 효과 제시를 통해 BIM 시대가 건축사에게 마스터 빌더의 위상을 되찾고 더 나은 기회를 제공할 수 있다고 강조하였다. 이번 연재에서는 BIM이 얼마나 다양한 분야에서 활용될 수 있는가를 살펴 보고자 한다. 건축사는 건축 프로젝트의 전체과정을 이끌고 코디네이트(coordinate)하기 때문에 자신이 구축한 BIM이 어떻게 다른 분야 또는 다양한 목적을 가지고 활용될 수 있는 것을 아는 것이 중요하기 때문이다. BIM은 설계단계뿐만 아니라 시공은 물론 유지관리 단계에 이르기까지 다양하게 활용되는데 이 중 몇 가지 중요한 활용분야를 살펴보자.

플로팅건축은 기존 육상의 건축과 달리 다양한 주체와 복잡한 협업이 이루어지므로, 분야별, 단계별 협업에서 프로젝트 참여자들간의 긴밀한 의사소통이 요구되어 진다. 효율적인 정보관리를 위해 국내 외에서 이용되고 있는 BIM(Building Information Modeling)을 활용하면 플로팅건축 프로젝트의 효율적인 진행을 가능하게 한다. 설계프로세스별 정보수준에(LOI) 관한 기준을 정의함으로써 BIM기반 통합설계프로세스 진행시 단계별 적합한 정보를 제공하도록 하였다.

건설 프로젝트 단계별로 생산되는 다양하고 방대한 정보에 대한 효율적인 관리와 정보의 상호 교환 및 공유는 건설 산업의 생산성을 좌우하는 중요한 요소이다. 최근 건설 정보 통합에 대한 관심이 높아짐에 따라, 기획, 설계, 시공, 유지보수 등의 프로세스 및 엔지니어링 어플리케이션 간의 정보 통합에 대한 연구가 수행되고 있다. 하지만 BIM(Building Information Model)과 같은 정보 모델을 활용하여 정보를 통합 관리하는 것에 대한 연구는 상대적으로 건축 분야에 집중적으로 이루어지고 있다. 따라서 토목 분야에서 프로젝트 정보의 통합적인 관리와 업무 프로세스 별 엔지니어링 어플리케이션 간의 교환 및 공유를 위한 통합관리 시스템이 필요하다. 본 연구에서는 토목 프로젝트 통합 관리 시스템 구축을 위하여 토목 프로젝트 정보를 담을 수 있는 정보 모델을 설계하고, 토목 구조물 가운데 교량을 대상으로 하는 토목 프로젝트를 정보 모델에 적용해 보았다.

In order to facilitate the application of BIM technologies in construction projects, a lot of developed countries such as Singapore and the United States are developing a technology development road-map of BIM. In order to develop it, current status of BIM technology in domestic projects must be analyzed in advance. In this study, the element technologies of BIM was identified and the current status and the importance priorities of them were analyzed and evaluated. The result shows that the level of technology developments is behind that of other advanced countries in most of the elements. In technology importance analysis, the BIM based preliminary planning technology and the standards for BIM service contracts are ranked in the high position and their developments are also delayed in Korea. The results of this analysis could show the direction of BIM technology development and also be used for developing the technology roadmap of BIM.

When starting a new project, generally similar existing projet are searched. As Building Modeling Information(BIM) has short history and experience, the dependence on similar project is high. Small and medium sized design companies are depending on website search tool for information of BIM project besides companies maintaining the Database(DB) from lots of project experience. However, the information level and contents provided by websites differ drastically from each other which makes it difficult to utilize the information and apply cases. Furthermore, the different classification system of the sites makes the situation even worse. Therefore, we collected and analyzed over 100 BIM cases from 18 global websites, to develop a system for BIM case application. Result showed that over 90% of our subject pool provided basic information including the construction type, characteristics of the client (public/ private), location of the project, and detailed information such as primary usage. Moreover, the reasons for applying BIM where to solve problems of geometric design, building system like MEP and construction. Furthermore, there was a contrast between cases conducted only within Korea and cases conducted with other countries. While there was almost always helpful information regarding the administrative steps for Korean BIM cases, there was close to no information for projects carried out outside of Korea. These results could contribute to verifying the trend of information provision of the websites for BIM projects data, and this is believed to be helpful for developing an application system for BIM cases which have an organized information provision system and level as well as for bench marking.

As construction project has been becoming larger, specialized and complicated, it is important to utilize a lot of information that is made by diverse participants. Especially this information is mainly produced in construction site that plays a leading role in construction project. The problem of information exchange between participants of construction site causes decline of construction productivity. So as to resolve this problem, there is a many interest in BIM(Building Information Modeling) that makes and manages a necessary data during building life cycle. But in Korea construction industry, applying BIM in construction phase is less active than in design phase. Through studying previous research, this study classify the main cause of failure related to information exchange in framework construction. And by interviewing expert, it draw a work that is possible to apply BIM. Next through analyzing framework construction site that is applied with BIM, this study proposes specific information flow model for supporting work by BIM.

In this paper, we have established the procedures for $CO_2$ emission estimation BIM libraries by using the material takeoff function that BIM tools fundamentally provide, and verified its availability by applying to steel structures. The BIM library set-up procedures were made up of $CO_2$ emission coefficients and parameter extraction, project unit setting, parameter setting, and $CO_2$ emission quantity calculation formula set-up. We used Revit Architecture 2013 as BIM tool, and established the steel members' family libraries as BIM libraries. It is possible to calculate the $CO_2$ emission quantity by following the proposed BIM library set-up procedures, and users have only to input the $CO_2$ emission coefficients and unit weights of steel members being used. We expect that the results contribute to practical use of BIM in field, and vitalizations of the eco-friendly construction.

Quantity take-off is one of the critical tasks that determine the cost of a construction project, and its result should be accurate and reliable. BIM-based quantity take-off is a very attractive process for practitioners since the quantity take-off can be done automatically in a fast and accurate way. However, the result of BIM-based quantity take-off can be varied depending on how BIM was modeled. As a project progresses, more detailed design information is getting available, and it can be expected that the degree of completeness and accuracy for the BIMbased quantity take-off is going to be improved as well. However, when estimation is performed at each stage of a project life-cycle, there is no way to measure or forecast how accurate of the quantity take-off result from the BIM data given at the current stage. Therefore, this research derived factors that affect the BIM-based quantity takeoff and developed a methodology and framework to measure and forecast the completeness of BIM-based quantity take-off. The measurement framework and index that are proposed by this research was verified and validated for their consistency and feasibility through six pilot projects.

본 논문에서는 BIM의 기술 중 하나인 DMU(Digital Mock-Up)을 실제 프로젝트에 적용하여 업무 효율에 기여한 결과를 소개한다. 삼성물산 건설부문의 경우 DMU는 건설 프로젝트의 입찰단계 및 시공계획 단계에서 적용되어 많은 성과를 거두었다. 입찰단계의 경우 대상 프로젝트의 교량, 터널 등의 구조물을 실제와 같은 지형조건 및 설계 조건으로 모델링하여 프로젝트의 개요 파악, 정보의 공유, 선정된 공법의 효과 분석 등에 적용하였으며 시공단계에서는 주로 복잡한 구조물의 철근 간섭 검토 및 효율적인 배근 방법 분석을 위한 도구로 사용되었다. 적용결과 공기단축, 원가절감, 시공성 향상에 기여하였으며, DMU는 향후 프로젝트 관리도구로 통합되어 구조물공사의 원가절감 및 생산성 향상에 기여할 것으로 예상된다.
