For running various construction processing information and technological information, it is supplied by Construction CALS/EC systems properly during whole facilities life cycle. So it is urgently necessary to change Regional Construction 8t Management Office (RCMO) equipment construction administration business to electron processing system (CALS/EC). From construction work plan to completion, a present storage documents system is unsystematic. Therefore, it needs management system to store documents and to read in turn documents properly. This research suggest that it is to connect with various information systems and Construction CALS/EC for RCMO which is running public construction field. So it can be driven systematic and effective administration system about public construction business by Web-based present construction situation information system.

Construction CALS contributed to informatization of public construction sector and to settle construction leaders' mind on informatization of construction project, however, the effect of Construction CALS has reduced as the CALS system has been aged and a plan for spread-out of existing systems has not been established. It is necessary to maximize the effect by developing a future plan after recognizing the current state. This study provided key factors that Construction CALS should take for the bright future by using SWOT Analysis, an useful method to develop a strategy. Considering interior and exterior environments surrounding Construction CALS through investigating existing studies, this study deduced twenty five strength, weakness, opportunity and threat points, and finally this study proposed fourteen critical success factors. The results of this study made a significant contribution to decision of the milestone that Construction CALS should take.

Recent construction projects consist of large and complex facilities, which project management information system (PMIS) is used for managing construction cost and schedule. The ministry of land, transport and maritime affairs (MLTM) is using a continuous acquisition and life-cycle support (CALS) system for managing the public construction projects. This study attempts to survey some problems of the CALS system in practical application, and then suggests the new functions to improve practical application of the CALS system. All functions in each menu were analyzed in the practical application aspect. All projects ordered from MLTM should use the CALS system as a PMIS, but the practical application is limited in partial functions and special working group. And the utilization of system is focused on simple tasks and report process. One of main reason is that the system is using numerical data rather than graphical data. This study suggests new functions and a visualized management method that can improve the practical applicability using a 4D object in each current functions.

Recently, most corporations in Korea need to construct new management system for overcoming economic crisis. Firstly, this paper suggests “Value Creation system”. Secondly, this paper suggests CALS as strategic substitute to achieve market efficiency, capital efficiency, personal efficiency, and operation efficiency, which are four critical factors of “Value Creation system”. Korean corporations should build new business model founded on cooperation by completing CALS system and reconstruct competitive management system by using knowledge and know-how accumulated in that process. Because most corporations keep exclusive corporate culture and little experience of cooperative relationship among businesses, strategic approaches are essential for construction of CALS. These are vertical integration, organization of CALS construction teams, concurrent development of product/process, CEO's iron will, Precise vision and strategies, and education/training of participant.

Ministry of Land, Transportation and Marine Affairs(MLTM) has implemented Construction CALS project for improving productivity of construction industry and for making construction project management efficient by responding to informatization and knowledge base society in 21st century. CALS has beeb applied successfully to projects form MLTM, however, the outcomes of Construction CALS hasn't been recognized. In addition, there is no way to find how high the level of Construction CALS is when it is compared with other SOC informatization projects. This study found out the informatiziation level of Construction CALS by using the evaluation index proposed in the former study, and by comparing with other sectors. The evaluation on the level was implemented in the three parts such as informatization infrastructure(network, hardware, standardization, data, informatization, informatization security), informatization utilization(information usage, IT performance), and informatization support(informatization goal, organization of informatization, informatization investment, informatization education), and then, this evaluation was compared with "Assessment for level of industry information system", "Assessment for level of small and midium sized industry information system", and "IICI(Informatizaion Index for the Construction Industry)". With the result from the comparison, this study produced superior factors and inferior factors for each sector. These results are expected to be useful for prioritizing budget allocation by finding out the informatization level of Construction CALS.
