Unanticipated market conditions as well as project-related risks can easily lead to cost overruns in international construction projects. For a contractor to be financially successful in international projects, a careful examination of the project is a prerequisite to understanding the cost variance characteristics. Based on the reasonably accurate characterization of the cost performance, the markup or contingency amount is determined to ensure both a decent level of profit and a good chance of winning the contract. This paper presents a classification model to categorize international construction projects, particularly faced by Korean contractors, into five cost-variation classes: extreme cost overrun, moderate cost overrun, neutral, moderate cost saving, and extreme cost saving. The model is able to characterize an international project for its cost performance prediction in comparison to the contractor’s initial cost estimate. A linear discriminant analysis is utilized to develop the predictive class...

International construction projects do not necessarily produce a high level of profit, as opposed to what is generally expected of high-risk international attempts. Overseas construction projects tend to have various risk factors that can diminish project profitability. This paper provides a comprehensive hierarchical framework to investigate the cause-and-effect relationships of various profit-influencing factors for international construction projects. After long-term profitability trends are analyzed based on a total of 3,487 international projects performed by Korean global contractors during the last 4 decades, case surveys of 126 overseas projects are conducted to draw the criticalities of each factor and to develop a hierarchical framework. An in-depth comparative case study of 20 additional international projects is also performed to verify the applicability of the hierarchical framework. Finally, we present significant distinctions between successful and failed projects from the comparative case ...

International projects are inherently exposed to unpredictable and complicated risk scenarios. To minimize possible losses due to these risk exposures, construction firms have their own procedures or basic tools for selecting potential projects, but they are usually based on the experience and knowledge of the firm’s engineers and decision makers that are often very subjective and lack scientific basis. This paper presents a quantitative profit prediction model for the early stage of an international project as a systematic risk-screening tool that involves the processes of defining, analyzing, and evaluating various profit-influencing risk variables. Various successful and unsuccessful international project cases with respect to profit levels are collected. Then, a scale-based profit prediction model to select candidate overseas projects is developed through factor analysis and a multiple regression analysis. Finally, this paper provides implications for global project management and lessons learned from...
