To the success of the megaproject including various and complex facilities, it is needed to establish a database system. Developments in data collection, storage and extracting technology have enabled iPMIS to manage various and complex information about cost and time. Especially, when we consider that both the go and no go decision in feasibility, Cost is an important and clear criteria in megaproject. Thus, Cost data modeling is the basis of the system and is necessary process. This research is focus on the structure and definition about CBS data which is collected from sites. We used four tools which are Function Analysis in VE, Casual loop Diagram in System Dynamics, Decision Tree in Data-mining, and Normalization in SQL to identify its cause and effect relationship on CBS data. Cost data modeling provide iPMIS with helpful guideline.

A construction project's period is limited by the order manufacture. And a construction project is requested a specific place, and has the characteristic to be irregular. Today, construction is to be representative high-cost and low-efficiency. This kind of problems appears in small construction projects more often than large construction projects. According to this facts, we recognized necessity of making practical application in methods of construction management. Also, we suggest application and establishment of integrated responsibility management department, PMIS(Project Management Information System) and Data Base. From now on, methods of construction management could be good opportunities for small construction projects and local construction companies. Therefore, small and local construction companies should try to improve their abilities. Likewise, the countries systematize to constitute the relation laws.

Today's construction is a large-scale and long life span program, so called Mega-scale project, that every moment constructor faces much of hardships, It is because of a large amount of stakeholders, data and complicated relationship among workers. In order to overcome these problems, IETM(Interactive Electronic Technical Manual) has been introduced to construction industry recently, It is regarded as a useful tool for handling the data, procedures of the construction, but it is similar to existing IT-based information systems, the PMIS(Project Management Information System) and the KMS(Knowledge Management System), without characterizing. This research is intended to find out IETM's property and to present the Ontology scheme discriminating Construction IETM from existing systems..

Most recent programs in and out of the country are related to urban renewal projects. Contemporary project management information systems have been developed was to manage single or multiple projects focusing on their construction phase, and those have limitations to apply to large-scale complicated mega projects. So, this study explain the core concept of decision support modules for iPMIS (Intelligent Program Management Information System) and its major functions to support project owner and participants by introducing ontology in the web environment. This study confined the scope of research to the planning phase of urban environment improvement projects. Ontological logic structure and relation about planning works is essential parts and three functions to implement decision support module are developed.

The construction data should be controlled from the life-cycle perspective. The current PMIS (Project Management Information System) usually focuses on the construction operation stage. The PMIS does consider the utilization of the construction in the maintenance of constructed facilities. This paper tries to interface the construction data with the maintenance data for effective use of construction data in the life-cycle perspective. To achieve the research objective, a maintenance breakdown structure is established and connected to the work breakdown structures. The connection of the two breakdown structures provide a structured utilization of construction data for efficient maintenance work activities. A prototype suggests that the interface of maintenance and work breakdown structures can help provide a construction and maintenance data in a more efficient way for maintenance activities.

Owners, local autonumous entities, have a burden on operating project for the lack of their management capacity such as specialty and human resources. In this reason, they want to perform project with CM methods. But there have been only a few case of CM operation and application in a huge construction project. The complex formations of CM and responsible management are used in those project. This situation originates in the lack of CM specialist. Because the CM service used in those case is generally performed as the mixture of responsible management service and design management service, it is not the prototype of CM. The purposes of this study are to present the solutions to the problems concerned with the design development phase management, design phase VE, the application of Fast-Track, PMIS operation and CM execution, etc, and establish the plan to perform CM services efficiently in the public sector through analyzing the case of CM application in Gwangjin-Gu Culture & Sports Center.

As construction projects are getting larger, more complex and specialized, the size and scale of the structures are increasing and large-scale projects with multiple participants involved have continuously been ordered. Due to the nature of a large-scale construction project, when there are interferences and conflicts in process, schedule and area among project participants, the project requires more time and efforts to resolve the issues as it progresses further. This study suggests the interface management model that is time-saving and physically beneficial in solving interface issues based on case study. This study provides a practical management model including the organization of interface consultative group, checklist preparation, LIST management and PMIS application, which will be useful for the construction sites seeking effective know-how to manage design interferences and changes.

The whole of industry sectors are getting achieved BPR(Business process Reencountering) which innovate the inefficient product organization through examined the value chain. Besides, they try to integrate ERP, CRM, and SCM which is based on value chain. Construction Industry, however, not only is not regularized it but is not inadequacy about information mind. Nowadays Korean government lead the construction CALS, only some large company Innovate and restructure the organization and product structure. It Is necessary to efficient manage the project information and historical data and develop CIC/PMIS to transfer from the function based information-flow to the project based information-flow. The purpose of the Information management system's success In Korea, therefore, this paper analyzes the information-intensive problems and proves the device to achieve the Information Management System through the Standardization, Synchronization, Centralization for Construction Company.

Claims in the construction industry can have a serious impact on the profitability of the project or can even result in project failure if it fails to take appropriate prevention. In order to properly prevent and respond to the potential claims and legal disputes throughout the project execution, it is necessary to continuously accumulate informations and clearly define the roles and responsibilities of the important activities systematically. Based on these needs, this study develops and verifies the project information management system(PMIS) that can prevent and respond possible claims for construction projects. Developed system includes such management modules as schedule, cost, PM/CM, design, collaboration, and claims. The system was validated by adopting it to the practical projects. The results showed that information systems tailored to the construction claim need to elevate users' familiarity to be more useful. Besides, the system can be more functional when used by both owners and contractors.

Earthwork is important in terms of construction time and duration, and highly related to the construction productivity. However, current earthwork system has stick to labor intensive process depending on skilled operator's heuristic decision making, so it is hard to improve overall productivity. To overcome this drawback, this paper presents a BIM based Intelligent Excavation System(IES). The BIM technology is applied in the excavation task planning system, Human-Machine Interface for remote-control/autonomous work environment, and web-based Project Management Information System(PMIS) in the IES integration process, and the results are addressed.
