Cost management is a major function of CM (construction management) companies for clients and cost estimating is a critical task in that it provides a baseline for cost management and a foundation for decision making in construction projects. For this purpose, CM companies need to obtain and use good quality data, which leads to more accurate and efficient cost estimating. As the use of big data becomes increasingly important in the construction industry, researches related to the theme have become the active areas of studies. However, literature review shows that the current situations in relation to the use of big for cost estimating of CM companies are under-researched. The objective of the study is to identify key characteristics and implications in the use of big data for cost estimating of CM companies, which can contribute to develop strategies for such purposes.

Since the interest in big data is growing exponentially, various types of research and development in the field of big data have been conducted in the construction industry. Among various application areas, cost estimating can be a topic where the use of big data provides positive benefits. In order for firms to make efficient use of big data for estimating tasks, they need to establish a strategy based on the multifaceted analysis of internal and external environments. The objective of the study is to develop and propose a strategy of the use of big data for construction management(CM) firms' cost estimating tasks based on the SWOT analysis. Through the combined efforts of literature review, questionnaire survey, interviews and the SWOT analysis, the study suggests that CM firms need to maintain the current level of the receptive culture for the use of big data and expand incrementally information resources. It also proposes that they need to reinforce the weak areas including big data experts and practice infrastructure for improving the big data-based cost estimating.

It has been passed around two decades since the CM is introduced in December 1996. And 20 years have passed. Construction Technology Management Act is the enacted of 1987, since Independence Hall fire in 1986. In the meantime, basic background and operational rather than the development of regulations that skewed had a voice of concern. Accordingly, Ministry of land is promoting a full-scale revision that Construction Technology Promotion law as switching to promote and support the necessity from Regulatory and management-oriented paradigm. In this paper, according to the Construction and Technology Promotion law amended in the course of doing business, was conducting research for drawn counterstrategy through SWOT analysis that was not the side of owner but CM company.

BAT Korea's Factory is the one of the major projects that clearly confirms and demonstrates that Construction Management (CM), provided by a Korean CM Company to the foreign clients, enables them to successfully complete projects; with savings in time and reduction in cost, which it is $15\%$ lower than the cost of the overseas construction. Also, throughout the thorough schedule management, it was possible to commence with manufacturing one month after the completion date. The Key Success Factors was generated by the excellent construction management skills, and more importantly by the confidence gained by the client in giving a CM company full authority for the construction management of the project. This study has focus on elements of construction management applied to this project throughout the concept of 'One Stop Shop', including cost managements, contract management and value engineering etc. We hope that this study will provide useful data to enable public clients to take advantages of construction management, in a similar way to. the private clients, who have already implemented CM actively.

The government has focused on activation of overseas construction projects and strengthening competitiveness in the long term. In recent years Public construction contract as well as design, engineering, construction management(CM) are gradually expanding into other countries, but risk analysis cases in the field are slight. In this study, We utilized PI scale and drew a conclusion about the importance of overseas risk by participants. We compared its features from the risk factor based on Risk Matrix. As a result of this study total of 6 section 31 Country Risk factors for the importance of overseas risk by participants were drawn, and the key risk factors (17 constructor, 14 designers, 17 CMr) based on Risk Matrix were derived. By utilizing the result of this study will be used as the basic data for establishing risk management strategy to meet each business and planning evaluation model.

Construction Management at Risk (CMAR) is a project delivery method that enables CM companies to deliver projects at a Guaranteed Maximum Price (GMP). General contractors can apply CMAR from the initial design phase right through the construction phase to reduce risks and improve project performance. One of the major advantages CMAR offers is that it permits a general contractor to provide a comprehensive suite of preconstruction services, including estimating, a constructability review, value engineering, drawings and a specification review, green building, and Building Information Modeling(BIM), among others. However, general contractors in South Korea currently provide only limited preconstruction services using CMAR because few CMAR projects have yet been implemented in Korea and their experience using the method is therefore limited. This benchmark study of how foreign general contractors utilize CMAR in their projects, particularly during the preconstruction process, its purpose, and the roles and responsibilities of each of the different participants in successful implementations thus provides invaluable information and will serve as a useful guide for Korean contractors seeking to incorporate CMAR preconstruction services in their projects and thus improve the competitiveness of their construction businesses.

As the CM at Risk market grows recently, designers and CM companies that have been performing agency CM services have been showing their interests to participate in the CM at Risk projects. With the assumption that agency CM companies with a lot of experiences and know-how in the field of construction project management have created the circumstances to enter the CM at Risk market, this study investigates the competencies necessary for the agency CM companies to carry out the CM at Risk projects. The compentencies to run the CM at Risk projects were identified based on the literature review. A survey was conducted to identify the competencies that need to be supplemented first. The survey results revealed that competency related to partner companies, finance and guarantee, risk and claim, and project cost were identified to have a higher level of complementation compared to other competencies. In addition, considering that the level of competency that need to be secured is high, as the level of holding of all competency is on average 76% of the required level, in the beginning, small-scale CM at Risk projects with relatively low risk are mainly carry out, strengthening competency and then increasing the scale is considered more appropriate strategy.

To drive construction project successful, a construction manager with good competency is needed. In order to select appropriate construction manager, there should be a standard and a method for appropriately evaluating the competency of construction manager. There have been many researches on the competency of construction managers, but there are two points to be supplemented. One is that construction manager's competency measurement was not concrete and objective, and the other is that construction project performance directly reflects individual manager's performance. The purpose of this study is to derive a construction manager competency evaluation index by using the Notational Analysis technique that is used when deriving an indicator that measures the athlete's competency in sports. This analysis was drawn with Delphi method. Finally, the 'measurable behaviors'were derived that can evaluate the competency of construction managers. Through this, it is possible to express each manager's expertise, leadership, and personal characteristics in numerical expression. This will help decision makers when selecting construction managers. It is anticipated that decision makers will be able to make the decision to select the necessary construction managers easier because it can evaluate the construction managers through a scientific approach based on the record by supplementing the existing method which only relied on intuition.

Since the global financial crisis, the Korean domestic construction market has continuously experienced downturns, and the Korean domain construction firms'profitability has been persistently deteriorated. Domestic construction firms have rapidly advanced to overseas markets exclusively for the construction contract packages. However, the profitability for the construction contracts has been lower compared to engineering or project management contracts. One of the critical issues the Korean firms have faced was project management capability across all phases in project execution. Even though several project management capability assessment tools were introduced, most tools were applicable to a wide variety of industry sectors rather than construction industry. Project management capability assessment tool specifically applicable to domestic CM firms was developed through this research, in order to assess project and program management capabilities and improve the competitiveness in overseas market Also, the correlation between project, programs, and the CM infrastructure were identified. The CM firms were divided into two groups according to the size of the business, and both were evaluated at the project and the program level based for the 9 different criteria. The project management capability assessment tool developed for the CM firms can be used for self-assessment to distinguish the strengths and weaknesses of each company at the project and program level. In addition, the current status of each group can be identified by spotting improvement areas for the management capabilities.

The 106 buildings of 200 meters' height or greater were completed around the world in 2015 (CTBUH, The Council on Tall Buildings and Urban Habitat). They beat every previous year on record, including the previous record high of 99 completions in 2014. This brings the total number of 200-meter-plus buildings in the world to 1,040, exceeding 1,000 for the first time in history and marking a 392% increase from the year 2000, when only 265 existed. South Korea recorded three completions during 2015 - improving slightly over 2014, in which it had one. This study focused on the fact that high-rise building development project risks have not reduced in Korea in spite of numerous studies and measures. And it attempted to examine whether existing studies and measures have been presented on the basis of the accurate analysis of existing studies and measures and classify and analyze the characteristics of each phase' s risk factors in the hope that its results would be one reference point as to the measure to prevent high-rise building development project risks in the future. A high-rise building development project is the high risk project as compared with the low-rise project. Because a high-rise development project takes long and is very sensitive to the changing environment. Therefore, in order to succeed the project it becomes necessary to effectively manage the risk involved in the process of the high-rise building development project. The result of this study can be used as the guideline to make the risk management system for the high-rise development project.
