Current global construction market has grown at a dramatic expansion rate every year in connection with more market accessibility by foreign contractors. The market openness is largely due to globalization of world construction markets, rapid development of world-wide telecommunication technologies, the formation of collaborative acquisitions and joint ventures among contractors, development of regional Free Trade Blocks, and just name a few. This paper focuses on the formation of collaborative networks when expanding into new foreign markets. The social network analysis (SNA) is introduced to investigate a variety of the collaboration patterns and also their impacts on the performance. To this end, the collaboration cases of 600 international construction projects performed by Korean contractors since 1990 were collected and classified into firm's size, project types, collaboration modes, and performance levels using social network analysis. The results showed a direction in establishing business strategy associated with experienced or inexperienced contractors in international construction projects.

The purpose of this study is identifying the relationship among the business strategy, order receiving capability and leverage variables of a construction company using industry characteristic variables, in addition to the explanation variables used in the previous studies. The samples of this study were limited to the construction companies listed in Korean stock market. This study built multiple regression analysis models, which have been frequently used in traditional previous studies, in the explanation of company capital structure. Empirical analysis on Static Trade-off Theory and Pecking Order Theory was done by the built model. The study results suggested that the capital structure determination behavior of a construction company generally follows Static Trade-off Theory; however, profitability was found to follow Pecking Order Theory. The explanation variables used in the previous capital structure studies mostly produced significant results; however, the variables, which this study experimentally used, did not produce significant results. It is believed that it implies that additional studies are required in the selection of variables and study methodology. Consequently, a case that unconditionally supports a particular theory is scarce. It has been also found that a case can support both theories at the same time. Therefore, it is believed that development study methodology or introduction of new study methodology that can identify the dynamic characteristic of construction company capital structure formation is required.

Since a government policy greatly affects markets and firms, an evaluation on government's policies is recognized as a critical issue. In Korea, two major policy plans on CM(Construction Management) include the Construction Industry Promotion Plan and the Construction Technology Promotion Plan from which Government's CM policies can be understood. The objective of the study is to analyze and discuss CM firm's perception and evaluation toward the Government's CM policies of the two plans based on the Gap analysis. The paper identified that the CM firms perceive that the Government's CM policies properly deal with key issues of the industry. However, they evaluate that the execution of the policies has been overall under-performed. As a way forward, the Government needs to improve on the execution plan and performance measurement rather than to develop new policy agenda.

Utilizing information and knowledge is one of the major objectives in the management of construction firm. This trend has been developed both inside of the firms and overall industry-wise. Therefore conventional methods of performance evaluation based on the financial statements such as balance sheet under GAAP(Generally Accepted Accounting Principles) are not sufficient to cover various Performance of constriction firms. Core competency of construction firms needs to be evaluated by the new performance evaluation model. In this research, the concept of BSC (Balanced Score Cards) is utilized to develop the performance evaluation model for construction firms considering four major performance indicators including financial perspective, customer perspective, learn and growth perspective, anti internal business perspective. A model of performance evaluation including criteria is proposed to evaluate construction firms based on their vision and strategy.

In recent, Information Technology(IT) is the biggest issue on the social whole including the construction industry. IT is recognized as a key strategic means to reinforce competitive power and raise the effectiveness. However, CEOs of each firm have trouble with IT investment decision-making. Because there is neither any case to measure real value of IT nor any confidence to economic effect of information system. IT evaluation is so helpful for most construction firms to make a plan of IT investment. In addition, which will eventually facilitate to achieve their management goal and have the maximum of the firms' value. Therefore, the purpose of this research is to develop IT evaluation system for monitoring IT level continually. And this will be enable a construction company to increase IT investment and improve the level of IT in the construction industry.

It is generally known that high strength soil is indicative of well-graded particle size distribution. However, there are some special cases of firm ground despite poor grade distribution, especially a specific gap-graded soil. Based on these discoveries, this study investigated the development of an additive of gap-graded soils designed to increase soil strength. This theoretical concept was used to calculate the mixed ratio required for optimal soil strength of the ground sample. The gap-graded aggregate was added according to Plato's polyhedral theory and subsequently calculated ratio and soil strength characteristics were then compared to characteristics of the original soil sample through various test results. In addition, the underground stress transfer rate was measured according to the test conditions. The test results showed that the ground settlement and stress limit thickness were reduced with the incorporation of gap-graded soil. Further field tests would confirm the reproducibility and reliability of the technology by using gap-graded soil to reinforce soft ground of a new construction site. Gap-graded soil has the potential to reduce the construction cost and time of construction compared to other reinforcing methods.

As domestic construction investment has been gradually reduced, the issue of expanding overseas CM market has increased. Strengthening CM capability from the view point of project life-cycle is required in overseas CM market. However, current regulations institutionally force public CM services to focus on the construction phase. Therefore, Korean CM firms can hardly have the opportunities for accumulating technical competitiveness especially for pre-construction phase. Result of this study shows that the total efforts in terms of man-hours for the construction phase is found to be more than 78 percent in domestic public CM projects. In this context, this study proposes the policies and tasks for improving 'rigid man-hour placement', 'unreasonable CM fee standards', 'CM firm selection method', 'unreasonable business scope decision', and 'evaluation of owner's project management capability' in order to improve domestic CM Industry as well as to expand overseas CM market successfully.
