Research on the Application of GIS-based Measures in the Advancement of the CPMS

The Construction Project Information System (CPIS) is an information system constructed as part of the Construction Continuous Acquisition & Life-cycle Support (CALS) of the Ministry of Land, Infrastructure, and Transport (MOLIT). As such, CPIS aims to digitize construction projects across all stages, improve the construction project implementation procedures, and enable sharing and exchange of information so as to enhance the productivity and efficiency of construction projects and secure their transparent administration. CPIS consists of five information systems -- construction project management, facility maintenance, construction approval, land compensation, and construction project information portal systems. Of these, the Construction Project Management System (CPMS), one of MOLIT's internal work systems, is designed to enable ordering agencies and constructors(designers, builders, and supervisors) to share documents, drawings, and other various information created across the entire process of road and river construction projects, and to process works online. CPMS, now over 10 years old after its construction, focuses on work processing functions and data management. Thus, CPMS's construction project information consists chiefly of text and documents, and makes it impossible to link with visualization-based Geographic Information System (GIS), thereby limiting its sharing and dissemination and the determination of the overall construction project situations. This paper examines domestic and overseas GIS technology trends and relevant information systems, analyzes the CPMS status and problems, and presents GIS application measures to advance CPMS. Thus, this study seeks to link text-information-based and documents-based construction projects information with GIS to assist in determining the total situation information and in decisionmaking, and to provide diverse statistics and analyzed information.
