The construction failures can be decreased by continuously improving the construction process based upon the information of construction failures. Herein, the information of construction failures can be utilized as the key factor far identifying the ineffective process and providing the improved construction process that can prevent failures. The objective of this research is to suggest a model for improving construction process continuously by using the information of construction failures. An extended review and analysis of literatures related to the construction failure are performed to investigate the definition, type, cause, and lesson teamed of failure. This research also identifies that process modeling methodology and case-based reasoning are applicable to the construction process improvement, and then it suggests a framework of CIMCP(continuous improvement model of construction process based on the module of case-based reasoning such as case retrieval, case index, and case adaptation.

For the purpose of analysing the capability (knowledge, experience, and ability) of CM at Risk in the major construction company in korea, this study performed questionnaire survey with experts in the companies. Based on the analysis of the survey, the study was found as follows. 1) It is needed to increase the capability of preconstruction services, such as project management plan/manual, contract documents, value engineering, alternative analysis, time management, and claim. 2) Despite of gap of the capability between the present and the future CM services, the study concluded that the capability is sufficient to perform CM at Risk project in the major construction company.

Credit evaluation by domestic financial institutions on Korean construction companies has had many problems with its tools and criteria ignoring the industrial characteristics. This study develops the DCiF(discounted cash inflow) model as a solution and discusses its usage in construction financing. It also examines the significance of the DCiF indices through regressions and statistical comparison with the other credit evaluation estimates. The results show its clear significance and consistent fitness. Based on the empirical results, implications and methodology are provided for the effective use of the indices in credit evaluation on the construction companies.

Korea government is making an effort to improve the efficiency in construction industry by introducing CITIS (Contractor integrated Technical Information Service). In order to provide a base for the application of CITIS into the construction industry, this research provides a concept of virtual factory which should be incorporated into CITIS system for the successful collaborative work in the virtual space. It then implements a prototype system through process and data modeling to apply into the road construction projects. The prototype system is tested to verify its efficiency. Finally, lesson learned from these works is provided to advance the current CITIS toward a collaborative virtual factory.

The processes for management of historical data in construction have many problems according to construction firm$^{\circ}{\phi}$s participating in some of the processes. This study analyzed about current process and provided improved processes with IDEF method and simulation. The proposed $\lceil$To-Be$\rfloor$ model is more effective than $\lceil$As-Is$\rfloor$ model according to the result of simulation performance. It is revealed that the productivity in the construction company is more improved than that of the owner from the results of the system simulation.

We study the RFID network system in a construction site, and study the connection method between the RFID network system and the integrated information system of construction material. Moreover, we developed a prototype of the construction site RFID server for the management of construction materials and performed the pilot application in a construction site. Through the pilot application, it was known that the proposed RFID network system can be more usefully applied in the construction sites. The results of the pilot application show that the RFID network system is faster, more accurate, and more reliable than the existing system of information management and achieves improvement in construction productivity.

The size of Vietnam's construction market has been on a steady rise recently, and foreign construction companies such as China and Japan have been expanding their presence. Therefore, this study examined the design capabilities, construction capabilities, and construction project management capabilities of Korean, Chinese, and Japanese construction companies operating in Vietnam and local construction companies operating in Vietnam. As a result, it was found that Japan, Korea, China, and Vietnam were competitive in order. In particular, Korea's competitiveness in high-rise buildings and plants has been shown to be highly competitive in Vietnam. Based on these results, the government proposed measures to strengthen the competitiveness of Korean construction companies in Vietnam.

Currently, construction engineering industry of high value and rapid growing has been viewed as a future oriented industry. Thus, compared to other industries, its analysis system for business trend seems insufficient. This research has developed a business survey index model targeted for construction engineering industries, and business trends for 4/4 quarter of 2011 as well as 1/4 quarter of 2012 were surveyed as important traits were analyzed. Business Survey Index of Construction Engineering has been constructed in form of an index in order to accurately judge different economic states of the industry such as funding areas, human resources, payability, ordering scale, status of domestic and foreign markets, Difficulties in Management, and improvements in policies. In the future, CEBSI will not only be applied on the construction engineering industry, but it will also be used as the economic state of all construction industries as well as the prospect data. Thus, it will be utilized as basic resources that can establish systematic and accurate policies.

The relationship between keywords, found in all productivity related papers published in the KSCE journal for last 15 years, were analyzed in order to reveal a research trend in the area using text mining and A-Priori algorithm. As the results, it is found that the word of 'productivity' is most closely related to the words of 'work' and 'labor'. Futhermore, the word is somewhat related to those of 'factor', 'model', simulation', and 'work time'. It is also revealed that, on the other hand, the words of 'machine' and 'equipment' have little relationships with the keyword. This research will be a great help for academia to understand a research trend in the area of construction productivity.

Construction market situation has been changed quickly in the 21st century. One is a large variety of information, the other is the development of IT technology among the rest of the change. Accordingly, it is very important that information is managed systematically and made good use of broadly in proportion to the increase of information volume. Therefore, the purpose of this study is to propose a applicable classification system in the construction phase. First of all, the Construction Information Classification proposed by the government is studied to apply the actual work and to build a applicable construction information classification for construction project. A base of the applicable classification system is the Construction Information Classification, SMM and Materials classification(Public Procurement Service). The applicable classification system to control and manage the construction information is consist of the 4 types : Facility classification, Element classification, Work classification, Resource classification (Materials, Equipment, Labor).
