현재의 NATM터널에 대한 물량은 설계도면을 기반으로 산출되는데, 이러한 방법은 수작업에 많이 의존하게 되므로 실수로 인한 물량의 오류와 사람의 능력에 따른 물량의 차이가 나타나게 된다. 본 연구는 BIM기반의 모델에서 자동적으로 물량을 산출하여 물량산출의 오류나 차이점을 바로잡고 설계변경에 따른 물량산출작업을 효율적으로 수행하려는 프로젝트에 필요한 BIM 모델링을 통한 물량산출 프로세스의 가이드라인을 제시한다. 또한, 여러 BIM 프로그램들은 각각의 모델링 및 물량산출 방식을 가지고 있어서 하나의 프로세스로 통합하기 어려운 문제가 있기 때문에 본 연구에서는 Autodesk사의 Revit Structure에 적합한 작업 프로세스에 대한 가이드라인을 제시하며 NATM 터널의 전체 구간이 아닌 본선구간만을 대상으로 한다. 본 연구는 전체적인 NATM 터널의 BIM기반 물량산출 모델링 프로세스를 BIM 모델링과 BIM 물량산출로 분리하였다. BIM 모델링 프로세스는 물량산출의 대상과 범위 설정, 모델링을 위한 CAD도면 작성, 패밀리 파일의 설정, 공종별 모델링 작업으로 구성된다. 물량산출의 대상과 범위 설정 단계에서는 NATM 터널의 CAD 파일과 수량 산출서를 분석하여 물량산출을 위한 공종별 물량산출 범위를 확정하고, 도면에 표시되지 않는 물량정보를 파악하여 물량 값을 정확하게 산출할 수 있도록 하며, 모델링을 위한 CAD도면 작성 단계에서는 Revit Structure 특성을 고려하여 모델링에 참조하는 CAD 도면을 Revit Structure에서의 모델링에 적합하게 편집해야한다. 그리고 패밀리 파일의 설정과 공종별 모델링 작업 단계에서는 CAD도면과 Revit Structure의 패밀리 파일과의 단위를 일치시키고 NATM 터널의 특성에 맞게 공종별 모델링을 실시한다. BIM 물량산출 프로세스는 모델링 데이터의 분할, 패밀리의 재구성, 물량산출로 구성된다. 모델링 데이터의 분할단계에서는 물량산출의 목적에 맞게 CAD에서 기준선을 작성하여 공종별 모델링이 작성된 패밀리 파일로 불러온 다음 모델을 분할해야한다. 그리고 패밀리의 재구성과 물량산출단계에서는 분할된 공종별 모델의 패밀리 파일을 프로젝트 파일로 불러온 다음 물량산출의 목적에 맞게 재배치하여 물량을 산출한다.

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.

As BIM is now being accepted and broadly expanded in the building industry, the demand for developing, managing, submitting, and checking the BIM models has increased. To meet this demand, it is necessary to develop and spread BIM guidelines, standards, and manuals. Meanwhile, as the number of public construction projects increases, the importance of quantifying the BIM quality checking and evaluation also grows. This study aims to enhance our understanding of the definition and characteristics of BIM quality management, and review the current situation of BIM standards worldwide. In particular, by focusing on BIM quality control and its relevant subjects, the minimum standards for BIM quality management are suggested.

In the trend of building enlargement, high-rise and irregular shaped building, domestic application of BIM in construction phase is increasing in recent years. BIM that is based on a three-dimensional, requires a specific building expression. Model expression level required for each phase such as design, construction, and maintenance of the construction project can be different. BIM model to apply in practice is difficult because it is not clear to set up the criteria for the expression level of construction BIM model. And it has a limit that is lower productivity in construction project. Therefore, this study considers the way of the improvement and analyzes the application for representation level of construction BIM model through the survey. By analyzing of the survey results, this study will be to present a basis for an appropriate expression level setting of construction BIM model.

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.

Domestic and foreign software components are rapidly developing continuously. However, the government's plan to activate BIM remains relatively sluggish. In particular, BIM based information management systems have been developed to enable the development of degraded railway industries in infrastructure BIM based areas. For this purpose, we analyzed domestic and oversea policies and guidelines. We conducted a survey on the personnel of the railroad corporation. Based on the survey result, the elements applicable to BIM were reflected in the system.

The Standard for BIM in Construction of China was released in 2017. The Unified Standard for BIM of China also took effects on 2017. The BIM standards of China needs to be compared with those related guidelines of Korea to find the status and characteristics for future development of BIM application in both countries' construction industries. The research methodology is a case study of comparing various standards of both countries. The case study results reveals many interesting issues for future BIM application and guidelines for practice of design and construction process. The research foundings include followings : LOD (Level of development) are well defined including LOD 350 in Chinese Standard. P-BIM(Practice based BIM) concepts and series of standards are set for the well-defined design and construction process by work stage in China. Korean standards shows more processes of design and documentation in detail. Major three aspects, particularity in BIM standard by work trade, practicality in BIM work process of design and construction, and professionality in subjects of BIM application, are analyzed and compared with various Guidelines of BIM in both countries.

The purpose of this study is to propose a guideline to help the client and bidder operate the BIM project in the domestic road field. As BIM design is mandatory in the construction field, documents disclosed by the ordering agency must essentially include procedures and step-by-step requirements to support BIM. The purpose of this study is to propose the structure and components of the guidelines that practitioners need practically by utilizing the currently announced road field guidelines. The guidelines are analyzed based on the procurement documents that were pre-emptively shared overseas, and supplemented according to the domestic situation. Furthermore, the effectiveness of the revised guidelines is confirmed through expert consultation. This study aims to contribute to creating an environment in which construction practitioners who have no experience in BIM project can efficiently carry out BIM projects.
