In the past CAFM system study, we proposed a system for supporting data-processing and plan-drafting, on the assumption that it is to be used in different stages of Building Construction, Interior Spatial Planning and Maintenance. By the above system, we have developed a CAFM system using the DBMS (Data Base Management System), CAD (Computer Aided Design) and Spread Sheet as the analysis tools. Management system with FM-related data editing functions such as'Input','Modification','Deleting', etc, are proposed. To promote the FM business smoothly, information should be shared among departments concerned, and informative administrative framework should be organized. This time, we propose a prototype of CAFM system on INTRANET which is developed for general users that permits browsing and downloading of system database.
