Contract design plays a key role in the life cycle of BOT project. All project management activities and operation processes are arranged in consistence with the document of BOT contract which the public sector ensures that the respective roles and responsibilities set out in the contract are fully understood and fulfilled to the contracted performance criteria. With limited theories to deal with some fundamental issues of BOT contract design, we try to collect data from case studies and formulate several practical principles. The conclusions presented in this paper are analyzed from two cases, one is based on an early case in the United Kingdom, and the other based on the Taiwan High Speed Railway case. The purpose of this paper is not about covering all legal issues about BOT contract design, but rather, our work provides common considerations applicable to the contract parties of a broad range of BOT contracts. The results in this paper shall propose some fundamental principles of the BOT contract design.

Determining on a particular construction method is typically decided in the initial phases of a project. However, changing conditions during actual construction may require a different method or technology to be employed. Providing an option for project managers to change construction provides flexibility that can increase value to the overall project. This research provides the ability to modify construction methods as a real option, which allows its value to be modeled. The research also formalizes a way to integrate a binomial lattice model with the Earned Value Method's S-curve. The integrated model provides a decision support tool that planners can use to determine whether to exercise the option depending on the status metrics provided by EVM.

The construction of bored tunnels in soft ground inevitably causes ground movements. In the urban environment these may be of particular significance, because of their influence on buildings, other tunnels and services. The prediction of ground movements and the assessment of the potential effects on the structures is therefore an essential aspect of planning, design and construction of a tunnelling project in the urban environment. In this study, to minimize the effect of tunnelling-Induced ground movements on the adjacent structures, a system for tile settlement risk management was developed. The GIS based risk assessment system for adjacent structures developed in this study consists of several modules such as building information module, settlement evaluation module, potential risk assessment module for adjacent structures, and analysis module for monitoring data. This system focuses on controlling and managing construction processes that may lead to settlement In the surrounding buildings and can contribute to producing the optimum technical and economic design.

웹 어플리케이션의 작성에 많이 사용되는 ASP로 개발된 프로젝트에서 각 모듈의 위험수준을 분석할 수 있는 측정 도구를 개발하고 이 측정 도구를 실무에서 사용 중인 프로젝트에 적용하여 유용성을 보인다. 본 논문에서 개발된 측정 도구는 NASA의 GSFC에서 개발한 소프트웨어 산출물 품질 메트릭인 모듈위험수준 인디케이터(Indicator of the Module Risk Levels)를 사용한 것으로, 웹 어플리케이션의 위험수준을 파악하여 오류 가능성이 있는 위험한 모듈을 조기에 발견함으로서 유지보수성 향상에 기여하고자 한다.

Recently, domestic construction companies have been moving towards overseas markets due to decreasing orders and an increase in competitiveness within the domestic market. However, there is a higher risk involved in the overseas construction Industry than in the domestic construction industry. Especially, because domestic construction companies lack development's experience, such a companies have a weakness of hidden risk factors. For Overseas New Town development project's success of domestic construction companies, preferentially, It Is necessary to deduce and analysis of risk factors in real estate development phases. This study would possibly be able to provide the preliminary data for Overseas New Town development projects in the future.

Although the depression of oversea construction market becomes more serious recent years, asian construction market is relatively dynamic, particularly in china. However, few research has been conducted about how to manage construction projects in china as foreign developers. Four important risks are identified from series of surveys using the WBS-RBS method, the result shows that the main risk of tender stage is 'Tender max price error', ' Bill of quantities error', 'Unusual low price' and 'Moral risk' respectively.

The Technology Readiness Assessment(TRA) has the advantage of identifying immature technologies in promoting weapon system research and development project. However, a more diverse set of information is required for the determination of phase shift and technical risk management for weapons system R&D projects. In this paper, we investigate the various indexes the various indexes proposed to overcome the limitations of the Technology Readiness Level(TRL) and analyze the possibility of applying to the actual weapons system R&D projects. Based on the analysis, it was possible to provide additional information that could not be presented in TRA using technical risk indexes other than TRL, confirming that it could be used for technical risk management for weapons system R&D projects.

The multi-disciplinary research project Strengthening Local Authorities in Risk Management (SLARIM), initiated by ITC, includes three case study cities in Asia. An important question is: what are the essential data for risk management and how to access such data. The role of common sources (e.g. census data), data derived from remote sensing (high-resolution satellite imagery, aerial photos), and data from close sensing (field observation, including mobile GIS) to acquire essential risk management data will be discussed. Special attention is given to the question of the minimum area and to disaggregating population data. A few examples are given of Kathmandu / Lalitpur, Nepal.

Microplastics with a size of less than 5 mm have emerged as an important environmental and food safety issue, as they have been detected not only in marine but also in terrestrial ecosystem and drinking water. Although many studies have been conducted on the exposure of microplastics and the effects on human health, the lack of standardized experimental methods for microplastics has been reviewed as a major problem. In order to overcome this, European countries such as the Netherlands and Germany are conducting a project to develop detection methods for microplastics as well as to establish the risk assessment methodologies for microplastics. Being the microplastics suggested to have a substantially potential risk on human health, reliable risk assessments should be conducted considering the various sources of microplastics, chemical pollutants and biological factors. In addition, international standards and regulations should be applied.

In the era of the 4th Industrial Revolution, smart technology being considered to improve productivity breakthroughs is in the spotlight as a means to replace traditional construction technology in the construction industry. However, various problems are occurring in construction sites using smart technology and causing negative impacts on construction projects. Therefore, the objective of this study is to identify risk factors that occur when smart technologies are used in construction projects. To achieve this purpose, this study investigated the difficulties at construction projects using smart technology, and risk factors were derived based on site surveys and literature. The risk factors were measured by experts, and then a total of 19 risk factors was derived by exploratory factor analysis. As a result, risks were classified as 5 factors, the institutional factor is the most difficult response, and the government needs anticipative system improvement and a long-term plan. The research findings provide practical implications for construction experts trying to apply smart technology in construction sites and construction policy-makers to revitalize smart technology.
