Recently, the design-build delivery system is being generalized in domestic construction project. The design-build system is becoming an increasingly preferable alterative to design-bid-build delivering method. In design-build project, however, a large construction company and design firm make up consortium as a design-build contractor rather than single company performs design and construction work. In this case, usually the construction companies take a leading role but due to their lack of managerial know-how in the design-build system, they could miss the merits of this approach. Therefore, it is necessary to investigated throughly the function and information flows all over the design-build project. In this research suggests a process model and database in the whole phase of design-build project. This process model and database system will also support to Improve the consistency of functional process and minimize incoherent activities in each phase of design-build project.

The purpose of this study is to find out how any organizational response or dispute-related consulting has a significant impact on management performance before or during a dispute over a construction subcontract dispute. In this study, multiple regression models were used to analyze the impact on consulting performance. According to the result of the analysis, the positive effects on the overall external consulting effect is influenced by five variables such as financial values, increase of the number of disputes, construction of response system by contents, construction of response system in each period, dispute response external response system. The original business operators were also more likely to be affected by internal activities of conflict response companies and the extent to which external response systems were established. This means that the supply and demand service provider's business environment is relatively poor, forcing it to be lower than the internal and external activities and influences of the original business operators of the conglomerates.

As the urban development economy is stagnating due to the reduction of the budget for Social Overhead Capital (SOC) and the stabilization policy of the real estate market, there is a steady increase in the interest of domestic construction companies to enter the overseas market. However, domestic construction companies are showing a decline in overseas urban development market as compared with advanced foreign companies having excellent financial management and overseas project management ability. Therefore, it is necessary for domestic companies to select an urban development model that meets the environment and the level of the country of entry, and to establish an advance strategy to manage the risks of overseas business. For this purpose, the factors of entry into the overseas urban development market through the existing research, literature analysis, and FGI were derived, and survey strategy and IPA analysis were conducted to develop strategies for entering the overseas urban development market. As a result, we have established a strategy for private companies to enter the overseas urban development market.

Recently, tunnel technology in Korea has shown various achievements such as long tunnel and large section by tunnel construction using TBM in Korea and abroad. Especially subsea tunnels are frequently designed and constructed. The Ga-deok subsea tunnel was completed in December 2010, and the Incheon North Port Tunnel was opened and operated in 2017, and the Bo-ryeong subsea tunnel between Dae-cheon Port and Won-san Island will be completed in 2021. In foreign countries, many subsea tunnels have been constructed and operated in such as Norway and Japan. The main technical problem in the construction of subsea tunnel is to secure stability due to high water pressure conditions and large-scale seawater inflow in fault zones and weak zones. In this paper, various risk factors and solutions are described in the subsea tunnel planning of national road 77 construction work between Abhae and Hwawon.

The extreme cold regions, including the South and North Poles, are rich in resources, but there are many constraints on resource development projects due to difficult access and a construction environment that is completely different from that of Korea. In recent years, global warming has increased the demand for the construction of resource exploitation plants. For resource development construction activities, a preliminary site analysis is required to minimize the risk of project implementation. In this study, the factors were analyzed to be considered in construction activities in extreme cold and optimal location selection system based on Geographic information system(GIS) has been developed. As a result of applying the development system to Alberta, Canada, where oil sand development is actively underway, it was confirmed that the results were consistent with the currently operating oil sand mining area.

After IMF bailout crisis in Korea, project financing has been employed as a major funding vehicle for the housing development. In 2008, the recession of housing market due to the global financial crisis had an significant impact on the increasing insolvent site of PF based housing development project, resulting in serious impact to whole economy as a chain effect. In order to resolve this vicious circle of bankruptcy, the major construction companies were urged to take over the insolvent sites and invest to them for normal project exit, and finally play a critical role in normalization of market. Therefore, this study aims to define the core factors for decision making to invest to insolvent site and find out differences among constructors, developers, financial lenders. The results from AHP analysis, the profitability was the most important factor to constructors. Moreover, even though the location merit is little less, through competitive price, we can assure that stable profitability is most important factor to decide to invest in insolvent site. In conclusion, the price is cheap, is highly feasible, if the land secured, major construction company will participate in a PF business investment. These findings were verified by the investment case of major construction company.

As the CM at Risk market grows recently, designers and CM companies that have been performing agency CM services have been showing their interests to participate in the CM at Risk projects. With the assumption that agency CM companies with a lot of experiences and know-how in the field of construction project management have created the circumstances to enter the CM at Risk market, this study investigates the competencies necessary for the agency CM companies to carry out the CM at Risk projects. The compentencies to run the CM at Risk projects were identified based on the literature review. A survey was conducted to identify the competencies that need to be supplemented first. The survey results revealed that competency related to partner companies, finance and guarantee, risk and claim, and project cost were identified to have a higher level of complementation compared to other competencies. In addition, considering that the level of competency that need to be secured is high, as the level of holding of all competency is on average 76% of the required level, in the beginning, small-scale CM at Risk projects with relatively low risk are mainly carry out, strengthening competency and then increasing the scale is considered more appropriate strategy.

The past IMF foreign exchange crisis and subprime financial crisis had a big influence on variability of macroeconomics, even if the origin of its occurrence might be different. This not only had a significant infrequence on the overall industries, but also produced many insolvent companies by being closely linked with a management environment of an individual construction company leading the construction industry. Actually, the level of default risk of construction companies before and after fluctuation of macroeconomics gets to experience a rapid changing process, and a difference in reaction against shock exists according to each company. Accordingly, the purpose of this paper is to confirm the fluctuation process of the default risk of construction companies under the fluctuation of macroeconomics such as the IMF financial crisis and the subprime mortgage crisis. As an analysis result, it is judged that the subprime financial crisis gave bigger shock to construction companies than the foreign exchange crisis, and it is expected that this would have a relation with the construction market before shock of macroeconomics. In addition, it was analyzed that when comparing insolvent companies with normal companies, the recovery speed of normal companies is faster. It is judged that this was affected by a difference of internal business capacity between insolvent companies and normal companies.
