In this research, risk factors which can raise project cost are identified in the initial stage and picked out through the decision maker's baseline. And also this probable risks are implemented to the project cash flow to estimate the contingency and to build a risk management system in the level of project. The risks that affect the projects profits were classified in two categories in the risk checklist. Firstly, financial risks derived from the external economic conditions for example exchange rate, escalation, interest rates etc. are analyzed through the stochastic methods, Monte-Carlo Simulation. Secondly, the project individual risks which are come from the project characteristics, for example country risk, clime, owner etc., are evaluated using the utility curve of the decision maker. Finally these risk analysis methods are used to forecast the actual project cash flow and final profit.

Overseas construction orders of domestic companies had been increased significantly in a short period from $10.9 billion in 2005 to $64.9 billion in 2012. However experts are concerned that quality of growth will not support quantitative growth. This study suggest concentrate competencies for not only winning in bid but also successful execution of domestic companies. 4 Steps which are Pre-Marketing, Bid-Preparation, Bidding, Contract Phase are defined for competency assessment. After drawing specific tasks by phase, survey asking importance and capability of the tasks to the person in charge of bidding and site was conducted by utilizing Likert 7 point scale. According to the result of IPA analysis, domestic construction companies need to ensure internal competencies; Project risk review, Bid team organization, and external competencies; Client needs grasp, Localization strategy, Cooperation establishment. Hearafter domestic construction companies will be able to utilize the result of the study for setting bidding strategy for winning in bid and improving earning rate.

From $1960^{th}$ Korean construction industry has been rapidly grown due to Meddle-East construction market growth. To earn foreign currency and to raise overall Korean industry government has encouraged construction frontiers. As construction industry could grow up for its labour based originity but the time passes by and overseas construction market requests engineering know-how and technology for productivity to earn more profit. Over last 20 years overseas construction market share has been dramatically raised but its profit share is gradually declining. This study analyzed data sets of over 180 overseas construction projects for last 30 years of domestic contractor by using multiple-regression analysis and derived an output how input variables of characters explaining the construction project effects its profit.

'세계는 넓고 할 일은 많다'. 건설사들의 시장 확대를 위해 미개척지로 발걸음을 돌리고 있다. 중국, 베트남은 물론이고 키르키스스탄, 카자흐스탄, 두바이 등 그동안 국내에 잘 알려지지 않았던 나라의 신규 개발공사 프로젝트를 따내는 경우가 늘고 있다. 해당 국가에 대한 정보와 경험이 부족한 점이 걸림돌이긴 하지만 해외 신규 시장을 확보하기 위한 건설사들의 질주가 한창이다.

Global construction market has grown rapidly since 2000. Even though developing countries grew into an economic, the most of oil-producing countries of continuous high oil prices due to an increase in plant construction orders is to present a lot of influence. According to the growth of global construction market, the domestic construction companies in the overseas market share have recorded 3% of the performance of the top 10 world records. However, current performance has analyzed the expansion of the market rather than competitiveness development of domestic construction companies. Therefore, to improve competitiveness in the global construction orders for the domestic construction companies in terms of long term, the government in Korea has ordered various research projects related to the plant since 2005. This paper presents not only global plant market trends and plant project in domestic but also introduction of completed research standardization recently.

This paper looks into how to enhance construction project management, focusing on the change order, which is often considered one of the major causes for construction delays, disputes, and claims in the middle east construction. First, this paper categorizes the major causes of change orders. It suggests a detailed classification standard for affecting factors resulting from change orders based on a case study result of an on-going construction project in the Middle East. In particular, this paper presents a method to apply a machine learning-based feature selection to quantify the importance of change order triggers and affecting factors. As a result, the case study identifies six major change order triggers and eight affecting factors. Also, a meaningful relationship between change order triggers and affecting factors by each category is presented. This paper will contribute to setting a clear guideline for change order management for the international plant construction field while helping prevent construction delays and cost run-ups by reducing the time required for change order resolution between project owners and contractors.

Recently many Korean large-sized construction companies as well as specialty contractors have been expanding their business in the overseas market to mitigate impacts from long-term stagnation in the domestic market. Such as a result, it has been arisen as a major issue that contractors effectively manage the delays which have been commonly faced with in international mega-projects. Therefore it can be said that the ability of the delays management leads a success of project. This paper presents a review of literature for delay analysis methods such as time impact analysis(TIA) and raises practical problems to rationally substantiate the duration of extension of time(EoT) in international mega projects which have wide scope of works as well as complicated and detailed contract baseline programs by taking theoretical approaches. We suggest the two improvement concepts to substantiate the EoT claims which are effectively applicable to practical projects. The first is to sort out dominant delays among numerous delays in advance of applying a delay analysis. The second is to set up the delay sections with the advanced concept for analysing delays' effects by TIA. This study performed a case study on an actual international mega-project. to confirm the effectiveness of improvement concepts that this practical approach is applicable for the assessment of EoT. In conclusion, this paper supposes to provide practitioner in charge for an EoT claim with an advanced substantiation methodogy when they not only analyse the construction delays by using TIA, but also negotiate with stakeholders about with the assessment of EoT.
