In the preparation of drawings and documents required for a licensing process, the main problem is the duplication of work in creating design drawings and Building Information Modeling (BIM) models. To overcome this problem, BIM authoring tools provide a drawing generation function. However, it is difficult to use it in a construction project involving multiple actors using different authoring tools for each design actor. Owing to these problems, the drawing generation program, which is based the on the industry foundation classes (IFC) concept is not limited to the authoring tools used in the project, and it is intended to minimize duplication by outputting drawings in dwg and pdf formats. In this study, the IFC data structure required for generating drawings was analyzed and drawing elements on the basis of the shape and attribute information, certain drawing elements were output as 3D scenes in order to obtain detailed plan, elevation, cross-section, and structural drawings, which are required for an IFC-based licensing process. In addition, 2D drawings were generated through post-processing for obtaining drawing-level outputs. On the basis of BIM design guidelines, it was found that the information required in license drawings can be minimized, and the license licensing process can be based on a separate BIM technology. In other words, based on the licensing environment in Korea, the effectiveness of the automatic 2D drawing generation program was verified through a comparative analysis on the basis of the drawings and information required by assuming that a specific set of drawing elements were required in the existing licensing process and for BIM-based licensing. Furthermore, it was examined whether books required in the licensing process can be replaced by a parking lot plan that can be submitted through a BIM-technology-based legality review system.

This study aims to develop an information strategy plan (ISP) for the integrated management of airport facility information in South Korea by applying smart technologies such as building information modeling (BIM), digital twins, and openBIM. As the demand for intelligent lifecycle management and efficient facility operations continues to grow, airport infrastructure requires standardized and interoperable systems to manage complex assets and stakeholder collaboration. This research addresses three core challenges facing Korean airports: the lack of sustainable maintenance environments, the absence of data standards and systems, and the insufficiency of user-oriented platforms. Through system analysis, benchmarking, and SWOT assessment, the study proposes a stepwise implementation roadmap consisting of development, integration, and advancement phases and designs a “To-Be” model that incorporates 37 component technologies and a standardized information framework. The proposed ISP supports data-driven airport operations, enhances collaboration, and accelerates digital transformation, ultimately contributing to the development of smart and globally competitive airports.
