Knowledge has been one of the key factors influencing the companies' competitive power. Domestic construction industries have introduced Knowledge Management from 1990s around major construction companies. However, construction organizations have recently give a skeptical response about Knowledge Management. The existing Knowledge Management in construction industries does not satisfy the demands of workers. Furthermore it makes workers do double business. Therefore, this study investigates the workers' satisfaction of Knowledge Management, and becomes the preliminary study to suggest how to improve Construction Knowledge Management.

In Korea, many mixed-used development projects(MXD) in mega project size are currently active. As these mega projects require long-term construction and execution and involve by different subjects in different fields, their completion breeds various problems, such as conflicts among project participants due to their complicated interest relationships and inaccuracy in predicting the economic performance of the projects due to inappropriate facility capacity planning. To solve these problems, it is essential to apply value engineering (VE) at the planning phase of the project, which can result in the best possible cost reduction and improvement of project performance. However, not many projects are actually implementing VE because of the lack of available information, as well as the limitations due to uncertainty in the early period of project execution. Therefore, this study aimed at proposing VE Team Building, Quality Model Performance Indexes, Space Model so as to resolve common mega project problems and overcome VE application limitations at planning stage. The result of this study is expected that the data can be utilized as basic data to apply VE at the planning phase of the large complex projects.

DOI : 10.6106/KJCEM.2011.12.4.50
Lean concept is management philosophy that defines a customer's value and eliminates wasteful and impeditive factors. Management philosophy of Lean in the construction industry is referred to as "Lean Construction". Now this concept has expanded to achieve effective productivity during the design phase. Currently the norm of the domestic design process has been Point-based Design(PBD). It involves selecting a single structurally-feasible design option early and then refining that single design as more information becomes available throughout the design process. This single design is then re-worked until a solution is found that is feasible for all parties. On the contrary, Set-based Design(SBD) is based on lean processes to eliminate waste and improve project productivity. It focuses on keeping the design space as open as long as possible, to allow "subdesign" to advance and not labeling them as secondary in importance. Preserving the maximum number of feasible designs as long as possible reduces the likelihood that rework will be necessary and allows all project participants to utilize their unique expertise to make the project successful. This study proposes that the design methodology of minimizing waste and increasing productivity through SBD of AHP, one of the decision making process so as to compare PBD with SBD and tries to find decision making process and then suggest that application methodology through performs case study of SBD process.

Construction works have become larger and more complex, improving productivity by introducing Information Technology (IT) is pursued. In this circumstance, many different kinds of project management system is being introduced, and various IT technologies are applied such as Personal Digital Assistant (PDA), Bar Code, Radio Frequency Identification (RFID), Web Camera, and so on. However, these kinds of technologies might cause reprocessing of information and ineffectiveness of project because of lack of real time information processing technology or separation between construction sites and management offices. Therefore, this research aims to develop Application that can be applied efficiently for construction material management, by understanding problems of former management system with questionnaires and extracting functions with analysis of requirements. This will be possible to input information automatically, to process and check material information in real time, and to identify the location of necessary material. Then, the problem of separation between construction sites and management offices are solved, and as a result, more efficient management of materials in construction sites will become possible.

DOI : 10.6106/KJCEM.2011.12.4.70
In case of long time progressive construction work, we need contract sum adjustment due to escalation for a period of works and the process of applying, consistent and obvious criterion is required. In this study, it were attempted to figure out problem and study this rational improvement by giving examples based on core activities of escalation adjustment. Based on literature study and legal system analysis, we classified processes of contract sum adjustment for escalation and defined 20 core activities for each process. From this measured variable, we carried out case study by giving 37 examples of escalation. As a result of case study, problems of each process was found and we suggested rational improvement. As this study, providers will be able to waste budget and the other will be given smooth escalation adjustment.

Cost control is an exceedingly fundamental and important construction business function. Even though enormous research efforts have been exerted in this area, there has been no comprehensive and quantitative study exploring detailed cost control practice of construction companies in terms of practical patterns and trends. This paper identified the variables for practical cost control process first. A survey questionnaire was developed and used in order to collect data from Korean general contractors. Survey results analyzing responses from 45 companies show that engineering aspects of cost management has recently been strongly stressed in the construction industry. Applying various types of progress measurement method are getting popular, and the level of details in collecting job site cost data are prevalent. Cost forecasting are performed more frequently. These trends indicates the recent efforts by Korean general contractors to achieve competitive advantages in the globalized market.

As many stakeholders are taking part in the Housing Redevelopment Project, their opinion mediation is considering very important issues. Thus disputes on projects are inevitable due to complexity of interest. To effectively progress the project, this paper analyze the risk factors by phase in implementation phase that the association participates in person. We identify 50 of risk factors in implementation phase by reviewing and analyzing related studies and actual cases of disputes, then we present 26 of risk factors through experts interview. Also, we calculate weights of risk factors by using AHP for quantitatively analyzing them and present final weights and priorities of risk factors by summing weights of risk factors by phase. In results, it is found that 'the inappropriateness of the Management Disposal Plan' in management disposal plan phase and 'the inappropriateness of the Project Implementation Plan' are the most significant risk factors. To maximize the utilization of risk factors analyzed, we present the checklists that can be aware of these risks in advance and prevent these risks. Based on these findings, if risk factors in implementation phase are managed actively, the housing redevelopment project will be performed more effectively.

It is very important to collect and manage labor information in the construction industry that is labor-intensive. Although research and cases that utilize RFID are increasing for more effective labor management, labor management is limited to the checking-in and -out information management at the entrance of a construction site due to high expense of an RFID reader. Labor and safety information is still managed based on the redundant process that is hand-written in a book and re-input of information by using a personnel-computer. Therefore, the objective of this paper is to develop more effective and efficient process for labor information record and management. This paper presents a prototype application that supports integrated labor information management by incorporating QR-code into RFID-based labor management system and verifies the application through a pilot test and comparison with the existing labor management syste.

Building Information Modeling technology (BIM) is one of the most effective solutions to deal with the trend that buildings are getting more and more complicated, large-scaled, and multiple-purposed. BIM in the construction industry is increasingly adopted since the Korea Public Procurement Service announced that BIM would be obligated in a construction project whose total cost is over 50 billion won from 2012. This fact has boosted BIM related research projects as well. However, the majority of the studies have been focusing on the solutions with technological points of view and there has been lack of research on how much degree project stakeholders are satisfied with the BIM adoption in their projects. Therefore, the objective of this study is to investigate the current status and satisfaction degree of stakeholders in a synthesized point of view in BIM-based projects in order to identify critical factors and weak points in the BIM adoption process. The results of this study would greatly help to improve the strategies and processes in BIM-based projects as well as to increase the satisfaction degree of BIM utilization in a project.

In the construction industry, there is a growing demand for new programs incorporating IT applications. In construction, initiatives calling for changes ensuring the improvement of productivity, quality and safety, and for the strengthening of global competitiveness, have contributed to the increased need for exploring new markets. Moreover, the government's supportive policies have helped develop profit models. Meanwhile, the industry and the government have supported the efforts for identifying and disseminating successful case studies - as part of the strategy for evaluating and promoting the developed programs. However, the criteria for identifying/evaluating successful cases remain vague, and the viewpoints of participants differ depending on their disciplines. These discrepancies could lead to inconsistent results. Thus, it is imperative that a criterion be provided, upon which to judge the success or failure of implementation cases and to disseminate role models. It is also imperative that a direction of improvement be proposed. This study was conducted to propose the criteria for and process of evaluating the success of construction-IT convergence to help promote the construction industry incorporating IT applications. To that end, success factors for and the significance of IT-incorporated construction were identified.

u-City projects are different with the existing urban development projects progress via convergence with IT technology. Therefore, it inheres many risk factors more than the existing development projects as including more complexity and variety. The risk management system to systematically manage those risks which get identified and quantified is required. Especially, the planning phase that is appeared the various forms has a large effect on the success of the business. However, the management of risk factors remains in the passive form. So the problems on u-City project in the planning phase and risk factors of existing development business were analyzed for the continuous growth and the successful performance of u-City project, and those risk factors was identified and quantified by using statistical technique. In the results of it, the core risk factors were obtained through which way and the basis for the effective risk management in u-City business is provided.
