Recently, BIM has been extended to infrastructures such as roads and bridges, and the demand for BIM standard development for ports is increasing internationally. Due to the low level of utilization of classification system and drawing standards compared to other infrastructures, and the closed nature of national security facilities, ports have insufficient level of connection and sharing environment among external systems or users. In addition, since the standardization of data for port facilities is not made, it is still necessary to establish an independent DB for each system and to ensure interoperability of data between these systems since it does not have a shared environment among similar data. Therefore, the purpose of this study is to develop and verify IFC, the international standard for BIM, in order to cope with the BIM environment and to be commonly used in the design, construction, and maintenance of port facilities. To this end, we build a standard schema with port-specific Express Notation according to buildingSMART International's standard development methodology. First, domestic and international reference model standards were analyzed to derive components such as space and facilities of port facilities. Based on this, the components of the port facility were derived through the codification, categorization, and normalization process developed by the research team. This was extended based on the port BIM object classification system developed by the research team. Normalization results were verified by designers and associations. Then, IFC schema construction was based on Express-G data modeling based on IFC 4 * 2 Candidate, which is a bridge candidate standard based on IFC4 (ISO16739), and IFC 4 * 3 Draft, which is developed by buildingSMART International. The final schema was validated using the commercialized validation tool. In addition, in order to verify the structural verification of the port IFC schema, the transformation process was verified by converting the caisson model into a Part21 file. In the future, this result will not only be used as a delivery standard for port BIM products, but will also be applied as a linkage standard between systems and a common data format for port BIM platforms when BIM is used in the maintenance phase. In particular, it is expected to be used as a core standard for data exchange in the port maintenance stage.

Recently, the application of BIM for port & harbour facilities has been increasing, as it is widely applied to the infrastructure field both at domestic and abroad. However, the port and harbour projects still have very poor facilities information management system and the application level of BIM is very low compared to other facilities. Even if BIM is applied for those project, it is very difficult to determine in advance what information is needed without an accurate understanding of the business process. The purpose of this study is to develop a BIM framework for port & harbour facilities and to examine its applicability. To do this, we structured the classification of the port & harbour facilities and constructed object-based classification system based on ISO12006-3 standard. We also derived the BIM framework requirements from the viewpoint of process, standard, interface, and information, and confirmed the linkage of the BIM object classification system in the framework item. The applicability of the BIM framework for inspection process cases of port & harbour was examined. Accordingly, this study can solve requirement setting method, which is the non - procedural and non - systematic project information, in the BIM application process of the port & harbour project with the BIM framework. In addition, the framework is expected to be integrated into the system to play a key role in the selection of project objectives, and the ability to clearly identify the information requirements required by the BIM manager to perform the project.

최근 스마트건설 확대 기조에 따라 건설 데이터 활용의 중요성이 높아지고 있다. 하지만 건설 사업정보와 유지관리 정보는 웹에 분산되어 있고, IFC를 통한 기존의 BIM 정보 교환 및 연계 방식은 BIM 데이터와 웹 자원과의 연결이 불가하다. 본 연구는 항만 유지관리 분야에서 BIM 데이터와 이종데이터의 통합적 활용방안을 모색하기 위해 링크드데이터(Linked Data, 이하 LD) 기술을 활용하여 BIM 기반 항만 시설물의 데이터 통합체계를 구축하였다. 이에 BIM 기반 항만 유지관리 온톨로지를 설계하고 BIM 시범사업인 부산 신항 2-1단계 3부두 시설의 BIM 및 사업·유지관리 정보를 대상으로 LD를 구축하였다. 또한, 발행된 LD를 활용하여 시설물 검색 및 통계, SPARQL Endpoint 기능 등 서비스 프로토타입을 구현하였다. 본 연구에서 제시하는 LD 기반 정보 통합체계는 기존 정보체계를 개방된 체계로 전환하고, BIM과 유지관리 데이터를 표준 형식의 웹 리소스로 구축하여 정보의 재활용성을 향상시킬 것으로 기대된다.

An IFC file is dependent on the IFC schema. Because of this relationship, most IFC-using software reads and interprets the IFC File by employing an early binding method, which uses a standard IFC schema. In the case of most open sources, early binding methods using standard IFC schema have a problem that they cannot express extra information of IFC File out of extended IFC schema. Also, in the case of previous studies, they suggested schema extension, such as adding attribute information to the schema, rather than the interpretation of IFC File. This study research on method of extracting shape and attribute information was conducted by analyzing the IFC File produced through the Port schema, which is an extended IFC schema. Three objects were created using the reference relationship between the Port schema definition and the IFC entity, and, at the end, the three objects were combined into one object. It has been confirmed that the shape and property data were express properly while delivering the combined object to the viewer. The process is possible because of the method of matching IFC schema and IFC File, which is dependent on IFC schema but not early binding method. However, this method has some drawbacks, such that contemporaneously generated many objects consume many memory spaces. Future research to investigate that issue further is needed.
