  • In 2011 and 2012, Korean construction firms awarded around $ 64.5. Billion each year from the overseas market in 2011. This contract value accounted for overwhelming portion of total overseas construction contract values, and this growth is expected to continue for the next decade. However, contract scopes awarded to the Korean construction firms mainly involve detailed design and construction phases due to their competitiveness for the construction techniques. In other words, front-end-engineering-design and construction project management are not considered part of core business due to the lack of project management skills and experience. The researchers focused on development of construction sequence model required to improve construction planning and scheduling skills for the Korean construction firms. The model identifies critical work items and the sequence throughout project execution process. In addition, the researchers developed a risk evaluation method by applying fuzzy theory to the critical construction activities for the industrial plant construction projects. Developed methodology will help project practitioners to develop project schedule in a timely and effe ctive manner and evaluate project risks associated with scheduling process for the industrial plant construction projects.

  • The domestic CM business market has continued to grow, but its size is relatively small yet in comparison with the total size of the domestic construction industry. Evaluation of CM projects was conducted through questionnaire surveys. Both clients and CM firms showed positive satisfaction levels. Nevertheless, the clients' satisfaction levels were relatively low in safety management, cost management, and document and information management. Superior areas of CM tasks were time management and recovery scheduling, quality control and technical instruction, and design value engineering. On the other hand, inferior areas of CM tasks were claim analysis and dispute resolution, cost estimation, and life cycle costing. Both entities have agreed with the positive effects of CM involvement in terms of cost saving, time reduction, quality improvement, and safety incidents prevention to at least 0~5% extent.

  • As the Fundamentals of Construction Business Act was revised in December 2004 and its implementing ordinances and enforcement regulations were adjusted in June 2005, the screening system of low price subcontracting has been an obligation to the public owners, having brought about arguments for and against since it enacted in 1983. The statutes for low price subcontracting have been reinforced from this year; for example, it underlines to submit to a project and builds an information network of subcontracting works. The system's original intention was that prevents shoddy and fraudulent constructions caused by low price subcontracting and precludes disturbances of fair trade by screening that whether it satisfies the conditions or not in advance. But, the criterion for the existing low price subcontracting has several issues having held up a true mirror to the real situation. It is arguable to discharge an important task with the primary purpose. This dissertation have researched the problem with a deposit of subcontract and the low price subcontracting basic rate are being used by the criteria for deciding whether it is a low price subcontracting or not, so showing the plan of reformation based on the findings, it wishes to contribute toward making the most of the system's essential intent.

  • It has been 10 years Since December 1996 when CM method was institutionalized by Construction Industry Fundamental law. Even though construction market has been in stagnant of business activities till now, CM in Korea started to be activated by the introduction of CM method i.n public construction. In the end of 2005, the number of CM order's contract is 6.7 times , an amount of CM order's money is 9.2 times more than operation plan of CM system announced in 2001. Therefore, CM market has been dramatically growing. However, it is judged that the shortage of faith in CM project and necessity of CM method are not recognized and study on a owner who affects successful settlement of CM has not been performed. When considering those points, in introduction and practical use of CM, CM is suggested to the field which is necessary for a client through the task performance level research and analysis of a owner who act a important role to activate Construction Management. As result of studying pre-existing papers to i.nvestigate of owner's capability level, the task function of a client is classified into 10 types and a public opinion poll was performed based on the 10 types of function.

  • The buildings are getting enormous and more complex as well as the requirement of the owner which wants diverse and efficient. Moreover advanced management is necessary for construction services and a new method of delivering project is now required. In order to expand the delivering method and the construction industry, we have to introduced the CM at Risk method. However, despite the fact that six years have passed already the CM at Risk regulation was introduced, the contract amount in significantly lower than that of the CM for fee, and also there is no CM at Risk project in the public sector. As a result, three pilot projects are currently underway for the LH(Korea Land & Housing Corporation) in order to set up a CM at Risk for the public sector. However, detailed regulations related to CM at Risk have not yet been implemented in Korea. Therefore, in this study, I am trying to understand the risks that could incur when practitioners participate in the three pilot projects that are currently underway and employed in the public sector wherein the CM at Risk is normally introduced. Based on the results of this study, It will be able to utilize as a basic data for future CM at Risk delivery system improvement and enactment.

  • This study analyses how much Korean visits to North Korea have an impact on the North Korean regional economy. It estimates the demand for North Korean tourism via the borders of North Korea, China, and Russia and South Korean expenses to be spent in North Korea. When asked if they are willing to visit North Korea within the next five years in case the pre-conditions of the visit to North Korea are satisfied, approximately 64.1% of the survey respondents indicated 'yes'. To estimate the demand, this research employed the analysis of purchase intention, popular in marketing, based on their willingness to visit. The annual demand for tourism was 4,136,361 persons. The average estimated expense per person is KRW 1,532,000 and the total annual expense is KRW 6,336.9 billion. Assuming that airfare is excluded from the total expense and the expense is made evenly in each tourist destination, the estimated amount to be spent in North Korea is KRW 2,838.7 billion per annum. The backward linkage effect of this expense on the North Korean regional economy is KRW 7,972.1 billion in total production inducement, KRW 2,619.4 billion in value-added inducement, and approximately 2,890,443 persons in employment inducement. The value-added inducement effect is estimated to be approximately 7.6% of the North Korean nominal GDP in 2020. South Korean tourism is expected to have a significant impact on the North Korean economy. As the demand for North Korean tourism is likely to increase steadily due to the expected increase in overseas travel demand by Koreans, inter-Korean cooperation is needed for the development of North Korean tourism infrastructure if conditions improve.
