In the Korean domestic construction field, there are a lot of problems related to construction information exchange and sharing owing to the absence of construction drawing information exchange standard. To remedy the aforementioned inefficiency effectively, it is necessary to apply the STEP standard which is known as an international standard for achieving the establishment of Construction CALS. This study focus on suggesting a methodology to activate the STEP based construction drawing information exchange standard to the current construction drawing information exchanging and sharing practice. In this paper, the domestic and foreign standardization projects related to the construction drawing information have been investigated and analyzed. In addition, a methodology of applying and activating the STEP standard has been suggested. Finally, a verification and certification methodology for applying the CALS/EC construction drawing information exchange standard(STEP) have been suggested.

국내 건설산업 전반에서 건설도면 정보교환 표준이 존재하지 않는 관계로 건설 정보 교환 및 공유에 많은 문제들을 발생시키고 있다. 이러한 문제점을 해결하고 건설 정보를 효율적으로 공유하기 위해서는 국제 표준이며, 건설CALS 체계구축을 위한 표준화 기술인 STEP(STandard for the Exchange of Product model data) 표준의 적용이 필요하다. 이를 위해 본 연구에서는 기존의 건설도면 정보의 교환 및 공유에 대한 문제 해결 방안 제시와 국내외 건설도면 정보 표준화 연구 개발동향을 조사, 분석하여 STEP 표준의 적용 방안을 제시하였다. 또한, CALS/EC 건설도면 정보교환 표준(STEP)의 적용을 위한 검증과 인증 방안을 제시하였다.

The drawing information takes the most essential part of construction information. The management of construction information through drawing information facilitates input, output and search process, thus helping maximize the usage of construction information by effectively sharing construction experience and drawing information. This paper shows how construction information can effectively used to increase the productivity of the construction process as a whole. Construction information was extracted and classified by the elements of building which are the basic and very end components of building, to accumulate information of each construction phase. Based on the result, the Element Breakdown Structure(EBS) was developed for the practical usage of construction information integration.

Construction industry, which is a composite industry being performed by organic combination of various tasks, gives birth to a various of information in the stages of planning, designing, and maintenance management. In particular, the drawing information is broad in the scope of use because it contains all information about buildings as wall as bid, materials, contracts. Therefore, the management of drawing information security is one of the most important factors, which determines the success of failure of business. The major findings and result of this study are as follows to control the distributed drawing information in the collaboration environment. 1) Analysis for function and practical use of DRM in the construction industry. 2) Proposal for applications of DRM that can secure IFC model-based drawing information in the collaboration environment. 3) Extraction from additional IFC entities to apply DRM to part 21 physical files 4) Analysis for functions which are necessary in DRM application prototype system and development of the system. 5) Development IFC model-based DRM prototype system.

The purpose of this study is to suggest the way of automatic building code checking for architectural drawings in the web environment to enhance the utility of CALS/EC standard drawings and efficiency of construction industry business. To fulfil this aim, the authors seek to standardize the architectural drawing automatic checking system by linked drawing information to the STEP based CALS/EC standard format. Therefore, the automatic building code checking system can represent a way of utilizing the relationship between the construction CALS/EC standard drawings and the related study as well as improve the efficient of the construction work by sharing a variety of drawing information.

Currently, it is necessary to share and exchange drawing information between 2D and 3D data in AEC(Architecture, Engineering & Construction) fields. The authors suggest an information model framework to express IFC(Industry Foundation Classes)-based drawing of 3D AEC products as 2D drawing. In this study, 1) an information framework has been developed to enable sharing and exchange of AEC product model by adding various information factors, 2) standardized APIs and an IFC2DBrowser are developed.

Recently, the needs for sharing and exchanging drawing information between 2D and 3D data in complex facilities are well recognized throughout the construction industries. The purpose of this study is to propose an information framework to represent 3D IFC (Industry Foundation Classes) -based drawing of building services in complex facilities as 2D drawing. In this study, 1) attributes of building service objects which are used in 3D CAD system are analyzed and present drawing standards are analyzed, 2) based on the analysis, an information framework is developed to represent 3D model in 2D representation, and 3) further more, to test a compatibility of the information sharing framework, number of standardized APIs and an IFC2Dbrowser are developed during the study.

In BIM environments for infrastructures, civil structures such as road, bridge and tunnel etc., created into 3D objects, integrated with their properties, securing BIM design productivity is very critical during 3D modeling. To solve this issue, configuring BIM libraries so that the users can utilize prefabricating in advance 3D objects that have been applying repeatedly during BIM design is essential so much. Current BIM libraries have made focused on Ready-Made for architectural facilities. However, establishing environment for delivering BIM library for civil facilities is very sparse. Accordingly, this study developed a web-based sharing system for delivering BIM library contents based on standardized drawing for civil area. To do this, we have analyzed core features and operation system of BIM library sharing system in domestic and overseas. Besides, functional requirements that are necessary for developing BIM library sharing system was derived, and through operation scenario configuration, the web-based system was developed according to the detailed mechanism. It is expected that this system can enhance BIM design productivity during library based modeling, and can be utilized as construction supporting tools that can help construction managers to make a design change.

During the lifecycle of a nuclear power plant many organizations are involved in KOREA. Korea Plant Engineering Co. (KOPEC) participates in the design stage, Korea Hydraulic and Nuclear Power (KHNP) operates and manages all nuclear power plants in KOREA, Dusan Heavy Industries manufactures the main equipment, and a construction company constructs the plant. Even though each organization has a digital data management system inside and obtains a certain level of automation, data sharing among organizations is poor. KHNP gets drawing and technical specifications from KOPEC in the form of paper. It results in manual re-work of definition and there are potential errors in the process. A data warehouse based on a neutral model has been constructed in order to make an information bridge between design and O&M phases. GPM(generic product model), a data model from Hitachi, Japan is addressed and extended in this study. GPM has a similar architecture with ISO 15926 "life cycle data for process plant". The extension is oriented to nuclear power plants. This paper introduces some of implementation results: 1) 2D piping and instrument diagram (P&ID) and 3D CAD model exchanges and their visualization; 2) Interface between GPM-based data warehouse and KHNP ERP system.
