The Project Risk Management is intended to result in the effective management by identifying in advance and mitigating all significant risks including project risks and opportunities during the entire project life cycle - from project inception to completion of construction. It is impossible to predict an exact budget and construction duration before finishing a project. So, Washington Department of Transportation mandates that workshop-based risk management is conducted for projects over specific cost. However, the domestic construction sites have depended on numerical risk analysis without any workshop and efficient risk management have not made. Therefore, in this study, we propose the effective risk management using the RBES program which is very useful for workshop-based risk management and pre & post mitigation, by workshop-based risk management techniques. This proposed risk management approach is applied to a domestic 'A' river recovery project. It is concluded that we may expect the effect to mitigate the total cost overrun problem and the construction duration delay effect in the project by identifying significant risks and by preparing effective risk mitigation strategies.

프로젝트에서 리스크 관리란 프로젝트 진행 시 발생가능성이 있고, 프로젝트에 긍정적 또는 부정적 영향력을 가진 이슈를 미리 발굴하여, 효과적으로 관리하기 위한 기법이다. 이런 점에서 리스크 관리는 프로젝트 목적 달성 즉 성공을 위한 수단이며, 예기치 못한 사건에 대한 사후대책 보다는 사전대책의 특성을 가지고 있다. 이러한 리스크 관리에 대하여 건설, 금융, 국방, 공공 분야의 프로젝트에서는 그 중요성을 인식하여 다양한 분야의 연구가 활발히 진행 중이고 현장에서도 활용하고 있으나, 소프트웨어 개발 프로젝트에서는 아직 그 중요성에 대한 인식이 부족하고, 현장에서의 활용도 저조하다. 반면 소프트웨어 개발 프로젝트에 대한 고객의 요구사항(비용절감, 일정 단축, 품질 향상, 신기술 적용등)은 점점 복잡해지고, 정교해지고 있어 제한된 리소스로 개발을 진행해야 하는 프로젝트 팀 입장에서는 프로젝트 성공에 대한 부담감이 점점 증가하고 있다. 본 연구에서는 리스크 관리를 수행한 프로젝트와 그렇지 않은 프로젝트의 사례를 비교하여 리스크 관리가 프로젝트 성공에 미치는 영향에 대해 연구하였다.

Recently, a delivery system has been rapidly changed in the global construction market. Also, construction projects are becoming bigger and more technology-intensive. A lot of projects have been delivered by Design-Build(DB) System; from the standpoint of cost, approximately 40% of delivered constructions by a Public Procurement Service were DB in 2009. Nevertheless, the achievement has not surpassed our expectations on management of the project cost. On the characteristic of DB, the reasons why that happens are that projects contract have been signed after the Design Development Stage; the insufficient review about new technology and up-to-date construction methods; a lack of discussion in process of design. Those reasons cause a risk of increasing Cost of the projects. In order to solve these problems, it is desirable to find Cost-increasing factors in promoting the projects and select on the order of priority for Risk-Factor with careful management. Therefore, this study analyzed the weight of each phase of the project on the authority of properties of DB project, and identified Risk-factors which is increasing the cost on the aspect of project management. Based on this analysis, the impact assessment of Risk-factor is evaluated through the Failure Mode and Effect Analysis(FMEA).

Space agencies such as NASA, ESA, and the US military provide guidelines and standards for PA(product assurance) requirements and plans. In recent years, major satellite manufacturers around the world have been mitigating PA requirements and processes by tailoring. PA tailoring has been implemented to improve the cost and schedule efficiency. PA tailoring can be accomplished based on various factors such as mission, classification of mission risk, complexity, development cost, life cycle, etc. In this study, PA tasks according to the mission risk classification proposed by NASA are investigated, and the tailoring method is suggested for the optimization of the development cost and schedule. In particular, the classification of mission risk for the satellites under development or operation in Korea is performed, and PA characteristics in accordance with mission risk are analyzed.

In this study, small and medium-sized manufacturing and distribution businesses were asked to demonstrate how the risks that could arise from implementing ITOs affect their performance. Small and medium-sized enterprises that want to reduce costs or secure competitiveness through outsourcing ITO conducted research to identify and analyze risks of ITO and improve corporate performance. Strategic, technical, and financial risks were selected as independent variables for analysis by the survey method. In addition, relationship risk was selected as a parameter and corporate performance was selected as a dependent variable to conduct a path analysis. The analysis showed that the variables injected as independent variables had indirect and total effects on corporate performance. This can be interpreted as the higher the level of awareness of strategic and technological risks and financial risks, the higher the level of relational risk, and thus the positive impact on corporate performance. We expect to improve corporate performance through analysis of more and more risk factors in the future.

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.

In the construction industry, not only safety accidents, but also various complex risks such as construction delays, cost increases, and environmental pollution occur, and management technologies are needed to solve them. Among them, process risk management, which directly affects the project, lacks related information compared to its importance. This study tried to develop a MATM tunnel process risk classification system to solve the difficulty of risk information retrieval due to the use of different classification systems for each project. Risk collection used existing literature review and experience mining techniques, and DB construction utilized the concept of natural language processing. For the structure of the classification system, the existing WBS structure was adopted in consideration of compatibility of data, and an RBS linked to the work species of the WBS was established. As a result of the research, a risk classification system was completed that easily identifies risks by work type and intuitively reveals risk characteristics and risk factors linked to risks. As a result of verifying the usability of the established classification system, it was found that the classification system was effective as risks and risk factors for each work type were easily identified by user input of keywords. Through this study, it is expected to contribute to preventing an increase in cost and construction period by identifying risks according to work types in advance when planning and designing NATM tunnels and establishing countermeasures suitable for those factors.
