Plant project is a complex project that consists of civil engineering, building, mechanical and electronic works. The schedule management is one of important factors in plant project because the construction duration of the project is very short comparing with the other construction projects. Specially, 4D CAD system needs to visualize construction schedule information in those complex projects. This study suggests methodologies for improving 4D CAD functions by considering those project characteristics. To develop a plant 4D CAD system, this study includes to develop new functions by analyzing actual schedule information from the plant construction sites.

The objective of this study is to improve the classification structure of commodity code for piping material management which is considered as the fundamental of commodity code and piping material management system. It enhances the efficiency of piping material management directly or indirectly affecting the engineering, procurement and construction in a petrochemical plant projects. To establish an improved code classification structure, this study identifies the problems of former code classification structure in details, as well as the characteristics of other domestic and global EPC company's code classification structures and presents the improved direction considering the recently mega-sized and specialized projects. Accordingly, to efficiently enhance piping material management, the improved code classification structures have been derived from defining suitable code classification structure for specific piping component, adding more standard attribute, expanding the number of code digits and classifying code hierarchy. The results of applying the improved classification structure of commodity code to on-going project have led to reduce the rate of rework from 4.98% to 2.48% for developing purchase description and also have saved working time for executing piping design by 3D modeling from 6 months by two persons to 4 months by a person which is decreased 67% consequently. In addition, the structures of pyramid code management have resulted to accumulation and analysis of the various piping data for other disciplines such as procurement and estimation team which require commodity code information through the company's material control system.

Existing 4D systems are using the 1:1 link system that directly links a schedule and a 3D model object. But considering that plant facility includes various kinds of schedule and 3D model object, this study suggests an improved link methodology of multi-selected objects and two-way link system for minimizing link errors which generated in case of multi-selected objects. For the link system, this study introduces a new concept called as interface board. Interface board can be used as an information center for representing all information of link items in the current project. It may be expected that 4D model can build an effective and rapid link system of plant project by this new approach.

Recently, The importance of modular construction method has increased by market environmental change. However, it's application in the actual project is restricted due to the lack of understanding of modularization and the absence of utilization system. To overcome this problem, this study propose the decision-making model for selecting modular or conventional (stick-built) construction method at early stage. First the needs of modular method in plant project is derived and the benefits and barriers of modular construction are analyzed through literature review. Based on this analysis, 6 decision-making factors covered project and modular characteristics are derived and the decision-making model is developed. Finally, 12 actual overseas project cases is evaluated by this model for verifying its applicability. This proposed model can provide the guideline to select the construction method in early stage for successful execution of plant project.

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.

Recently Gas & Oil plant construction projects are increasing in the world. The EPC (Engineering, Procurement and Construction) company, which participate in the plant projects, should possess the pertinent engineering license and procurement skill to create high added-value. It is because the procurement is very substantial to cover 70% of the total project cost. Nonetheless, there exist various risks involved in the procurement process due to the characteristics of the construction projects with long duration and complicated process as well as the procured goods or services subjected to various logistics. The objective of this paper is to analyze proper process in the procurement and to identify various information and document. Also to analyze procurement process, the principal data are derived from the interview with experts and specialty contractors of plant project. The result of this study would widely be used as a guide to the procurement personnel in forecasting the risks in advance.

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.

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 following the outbreak of Iraq war. 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 exposures through contract negotiation and its adjustment. 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 from real overseas construction projects and structuring their cause-and-effect relationships. The profitability causal 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 analysis. Ultimately, with this hierarchy structure as the base, the research will suggest how to develop the quantitative profitability forecasting model.
