Lowering threshold value of construction services is extremely sensitive issue to the small and medium enterprises in construction industry. Because it means opening the construction markets where the small and medium construction companies compete intensely. Nevertheless, it is absent that the analysis on the effect of opening the market lowering threshold value of construction services under Government Procurement Agreements or Free Trade Agreement. This research is to analyze the effects of lowering threshold value of construction service which have been agenda repeatedly in the international agreements such as WTO and FTA. The current threshold value of construction services of Korea under WTO GPA are 5million SDR where the government delivers and 15million SDR where the local government or the public institution deliver. However major parties to an entente such as USA and EU have been demanding to lower threshold value of 15 million SDR where the local government or the public institution deliver to 5million SDR. The analysis figure the effect of this lowering threshold value to be a market reduction by 2trillion Won as '07 fiscal year basis. This market shrinkage will effect to the small and medium construction companies in local considerably.

공공부문의 SW에 대한 사용자의 기대 및 정보화 요구에 부응하기 위하여 그동안 국내에서는 수많은 SW 시스템들이 개발되어 왔으나, 개발 과정에 대한 체계적인 관리 방법이 미흡하여 발주자가 복잡한 SW 발주과정을 추진하기 어려우며 SW 개발자에 대한 관리 통제수단이 미흡한 실정이다. 또한 발주자의 전문성 결여로 수주자인 개발업체에 과도하게 의존하는 업무 추진과 수발주자 간의 불명확한 업무 인식으로 상호 불신이 팽배한 가운데 공공부문 SW사업의 완성도 및 성공률이 저조하여 낮은 품질의 정보시스템 인수 등 사업 실패율이 높아지고 있다. 본 논문에서는 이러한 문제점을 해결하고 개선하기 위해 발주${\cdot}$관리 프로세스 확립과 이에 대한 적용을 중심으로 체계적인 SW사업 발주${\cdot}$관리 프로세스 확립과 이에 대한 적용을 중심으로 체계적인 SW사업 발주${\cdot}$관리 프로세스 개선방안을 제안한다.

In recent years, Korean engineering companies are actively entering into the international business. Although international engineering project is known to have lower risk rather that EPC construction project, Korean engineering companies' international sales profit is not as good. Therefore, this study analyzes the risks that are predicted before bid and actually occurred after award. In addition, this study shows the difference of risk depending on lump sum contract and cost reimburse contract. Finally, this study analyzes the difference of risk according to civil engineering and building engineering. This study provides industry to analyze risk more practically and helps academics to focus on risk to be studied more in the future.

Despite the recent depression of the construction industry, overseas plant market especially Middle East plant market is booming owing to the high oil price. Since many Middle Eastern countries are placing orders of big scale projects based on the high oil price, Korean EPC contractor are trying to get over the depression through theses plants. Presently, since the plant market is in prosperous condition in general, it is not hard to get overseas orders; however the original licenses that requirehigher technology and high added values are exclusive for advanced engineering companies which great difficulty is predicted for developing countries like us to join the crowd. Therefore, the objective of this study is to propose establishment of material management system on the filed to gain optimized effect of material management in connection with procurement system that all the procurement related personals execute tasks in advanced level by systemizing the task operation within the knowledge and task ability in time for plant construction procurement as a method to strengthening the competitiveness of Korean companies.

Korean contractors have been maintained sustainable growth since entering into overseas construction market for the first time in 1960' s. In 2010, Korean contractors ordered 761 billion (USD) from overseas markets. Especially, billion (USD) were earned by Korean contractors in overseas plant construction market which account for more than 80% of the total amount by Korean contractors. Nevertheless, many Korean contractors are suffering from lack of technological competitiveness and construction management skills in the design phase compared with global leading contractors. These conditions have directly effect on the success of projects in terms of cost, duration, and quality. So, this study focused on identifying the risk factors and developing risk priority method for the design phase of LNG plant projects whose market is expanding. Research procedures were conducted by the following three steps. First, total 57 risk factors were identified in design phase through extensive literature reviews and experts survey. Second, the authors developed risk priority method which are more suitable for design phase of LNG plant projects by using three criteria, Probability(P), Impact(I), and Coordination Index(CI). Finally, the suitability of risk priority method and practical applicability were verified through expert survey and interview. Consequently, if korean contractors use the suggested risk factors and priority method based on their own know-how and experiences, then more reasonable and rational risk management will be conducted in the design phase of LNG plant projects.

Small houses are continuously supplied after the alleviated housing act enacted in 2009. This study aimed to conduct a survey among an expert group associated with small house construction, propose problems by discovering difficulties and vulnerable points small and medium-sized construction companies experience while launching construction works as well as factors that impede the safety and housing environment of small houses. Furthermore, it ultimately intends to propose improvements. First, low-priced order is a major cause of unreasonable contract. Most companies were found to have low-priced orders in order to manage order performance. Low bidding and low-priced order are implemented to maintain construction businesses, ultimately threatening the safety environment of buildings. In addition, it is assumed that moderate bid periods and construction periods should be guaranteed. Second, work standardization for small and medium-sized companies is needed due to numerous cases that failed to meet order process. Additionally, regular instruction is required as many employees are not fully aware of relevant contents. Third, the most urgent policy direction turned out avoidance of low-priced bidding and removing insolvent enterprises from the market. Small and medium-sized construction companies that primarily build small houses undergo poor work condition. Therefore, the safety environment of small houses should be enhanced through work standardization and avoiding low-priced order.
