CM services have been increasingly practiced over the two decades in the Korean construction industry, and recent efforts focus on further development in advanced CM capabilities and expansion to overseas market. However, there has been lack of holistic research to investigate current status and future direction of CM industry in Korea. In this context, the purposes of this study are 1) to analyze current status of Korean CM industry in terms of owners, market, CM firms, contracts, and work scopes, 2) to define different types of CM practices, and 3) to propose growth models for Korean CM firms based on the defined CM project types. An extensive literature review and statistical analysis of 2012 CM contracts were performed in order to analyze the CM status. Based on the analyses, ten different CM types are defined, and growth paths of CM firms are illustrated. Implications and lessons learned during the statistical analysis and workshops are briefly introduced as well.

Recently the diversification of construction market and the continuous reduction of construction amount are raising the need of alternative delivery method in the construction industry. The foreign advanced companies actively adopted the CM at Risk delivery method where they perform the service of agent CM in the design phase, and agree GMP(Guaranteed Maximum Price) with the client at the time of 50~80% completion of design. Even in Korea they began to apply that method to pilot projects. In CM at Risk, through the early participation of builder, the level of design completion can be improved and the change order and construction period delay can be minimized. On the other hand, GMP is usually calculated when the design is about 80% complete, so there is uncertainty in the construction cost. Therefore, in this research, the increased amounts of construction cost are analyzed in a number of public construction projects, and GMP calculation process is proposed using the analysis results and CBR(Case-Based Reasoning) technique to reduce the construction cost increase in the construction phase.

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.
