Early planning phase of private development project is an important part in mercy of failure and success of all project. Hut reliability of analysis result existing planning phase in not high to the importance. So we analyzed a basic problem point through case study and research data analysis of planning phase in private development project. After this, there is a cause in no establishment of systemic model about work processing and method of planning phase. We would like to suggest the solution through establishment of planning phase analysis processing and risk management model. We think that suggested analysis method increase the credibility of analysis result. With this, we anticipate we suggest the guideline in project process phase and that assist the effective accomplishment of project.

Recently, BIM (Building Information Modeling) technique is being considered as a critical delivery condition for the public projects according to the increase of best practices by practical application of BIM. However, since existing BIM studies are focused on the design and construction phases, those results are not considering the life cycle of a construction project. Therefore, this study suggests an integrated BIM operation process that enables an application of BIM for each phase of a construction project from planning to maintenance phases and develops an integrated BIM system based on the suggested methodologies. This study developed basic BIM functions and its application process by analyzing information systems in each project phase for a bridge construction project. Besides, this study performed case study and survey analysis for construction managers to verify a practical applicability of the developed system. Therefore, it is expected that the integrated BIM system is going to be utilized as a 3D-based integrated information management system considering life cycle of construction projects.

The risk in the constructions projects is extremely diverse because there are too many indefinite factors. Therefore, Performance Measurement Baseline(PMB) is needed regularly during the construction process. However, nowdays, the PMB in the constructions projects is for contractors' PMB and Performance Management(PM). Clients have a lot of difficulties to control and manage the projects. Therefore, this paper classifies schedule and cost data of the public apartments houses which is a actual cases into types and then conducts regression analysis and deduces a regression. In addition to this paper establishes the Work Breakdown Structure(WBS) and suggests the PMB for the clients through using that.

Recently construction environment is being professionalized. oversized and diversified. Due to fluctuation of construction environment, the demand for the project of steel structure is ieased gradually and steel construction is needed the efficient quality management. The construction of steel structure which required a variety of sub-contractors, the progress of works and technologies are comprehensive of various risks and uncertain factors. But currently the construction of steel structure is conducted the risk management by perception and experience of constructors. Therefore, the analyzing factors of the risk and establishing the device are able to manage the quality management efficiently. In this study, we have conducted the interview of experts, polls and through the Analysis Hierarchy Process (AHP) for the scientific and systematic risk management. This paper will propose a plan for systematization of the construction of the steel structure.

The Korean Government recently has been focused on strengthening competitiveness of order and stimulating construction market in the international construction industry. It has planned to extend the ODPs (overseas development projects) in order to diversifying the international construction market of which is domestic construction companies, placing too much emphasis on plant projects of the Middle East. However, literature review of risk analysis in the ODPs shows that the number of case study is several. Therefore, Authors asserted the necessity of risk analysis in the ODPs. The purpose of this study is to suggest a methodology that find KRFs (key risk factors) in the ODPs and analyze them, using AHP and Fuzzy theory. As a result, the 37 KRFs are selected and explained characteristics of them. A future direction of this study is to suggest a risk management model in the ODPs and prove feasibility of it.

Korean construction companies first advanced to the international markets in 1960's and so far have brought more than 4,900 projects which account for 193 billion dollars approximately. With the large increase of national employment and income being followed by the achievement, Korea's construction industry has made an enormous contribution to the improvement of domestic economy for the last 40 years. However, recently the increased risk in international markets as well as the sharpening competition with foreign companies promising in terms of advanced technologies and low labor cost have been driving Korean construction away from the market shares. According to ENR (Engineering News Record, 1994~2003), it is revealed that 15.1% of top 225 global contractors are suffering from loss in international construction markets. This phenomenon is largely due to the highly uncertain characteristics of international projects, which are inherently exposed to various and complicated risky situations. Furthermore, especially for Korean construction companies, it is often the case that the failure in an international construction project cannot be offset by even a sufficient number of successful domestic achievements. Therefore, not only the selective screening among the nominated projects which have strong possibility of collapse but the systematic strategies for controlling potential risk factors are also considered indispensable in international construction portfolio management. The purpose of this study is to first analyze the causal relationships of the profit-influencing variables and the project success, and develop the profitability forecasting model in international construction projects.

With Public-private partnership PF (project financing) deals saw explosive increase in quantity since its introduction to Korea in 2001, but, met with severe recession in the fallouts of the financial crisis that hit the global economy in 2008. This study intends to identify the risk factors corresponding to issues of public-private partnership projects financing structure and classify and analyze them by project phase. Outcomes of this research are expected to help recognize risk factors in each project phase during project planning and develop risk control and mitigation strategy during project implementation.

Development work of apartment houses is a complex medium-and long-term project requiring grand resources and work force. Since in combination inner and outer project variables relate to project output, uncertainties caused by not only a given site condition but also politic, economy and social sectors are generated during the project. These risks influence output of the project as important factors, and ultimately as management variables in priority giving an effect on earnings and the financial structure of enterprises they should be manageable with the risk reduction plan. In this point of view, this study focused on development work of apartment houses among construction project. Risky factors were deduced, analyzed and evaluated based on Value Engineering from planning to designing to executing to maintaining. Eventually, this study showed the foundation guaranteeing competitive power of public and private construction sectors.

Korea's overseas construction industry has been rather depressed by the weakened profitability as well as the sharp decrease of the market shares due to the lack of international competitiveness and the declined international market. There exist a lot of various risks in performing the overseas construction, and especially EPC projects, which entail complicated process from different parts, also require a sophisticated procurement and management skill. Subsequently, to survive in the competitive international market, we need to establish strategies to select potentially profitable projects at the initial stage of bidding process and to mitigate the high degree of risk exposure through contract negotiation and its adjustment. This research discusses the trend of environment in international construction markets. Then, it identifies the key factors that affect the profitability significantly through the structured surveys from 59 actual overseas projects, and it analyzes the key factors by using statistical methods. This research provides the profitability evaluation bases, with which overseas construction participants can forecast and analyze the risk more systematically, by eliciting profit-influencing factors using the result of statistical analysis, literature review and structuring their cause-and-effect relationships. The profitability casual hierarchy structure describes the profitability factors' hierarchy in details and their interrelationships. It also enables us to find out critical factors directly related to profitability aggravation through a qualitative and quantitative analysis. Ultimately, with this hierarchy structure as the base, the research will suggest how to develop the quantitative profitability forecasting model.
