SOC(Social Overhead Capital) projects such as road, power plant, airport or telecommunication facility construction require a large scale of cost, a long period of time and management of a number of sub-contractors. So systematic and efficient management tool in SOC projects is inevitable. Information system provides a valuable tool which can integrate and manage the large volume of information for SOC projects. This study investigates and analyzes the information system of nuclear power plant construction project. Based on this study, we can suggest the direction for designing information system for SOC projects.
