Since the 1980s, Build-Operate-Transfer and its variations have become a common approach to develop large-scale infrastructure projects. Despite the slight variations in contractual settings, the key issue for all parties concerned is to assess the risks and uncertainties inherent in a project. The risk factors studied and highlighted by past researchers are very diverse. This paper starts with an objective to compare the risk factors in different sectors of infrastructure, and then categorize them into two kinds: general and specific. Following this classification, risk mitigation strategies should be adopted differently at the corporate and project levels. A few short cases have also been used to illustrate the flexible measures or "options" that some project participants have designed to address risks and uncertainties at the two levels.

As a recent global trend, the majority of mega-size plant projects are delivered through EPC (Engineering, Procurement and Construction) contracts, where a single contract is awarded for engineering, procurement, and construction. Under this contracting mechanism, it is challenging for contractors to carry out the projects under traditional project management processes used in design-bid-build projects. A new EPC Plant, the POSCO Special Steel Plant in Changwon, was built successfully at the beginning of 2012 and it is currently in full-scale production. The project has encountered a number of major difficulties however, with some technical and managerial issues through its development process. As summarized in this paper, the authors (as project participants with the contractor) investigated it as a post construction analysis and recorded the Lessons-learned for future project management improvement.

Project delivery systems determine the relationship, responsibility, authority and the scope of works of those involved in project, hence, optimum project delivery system should be selected to so that construction project would be executed successfully, Until now, the traditional design-bid-build mainly has been used for public projects, but the government is making efforts actively to introduce other methods such as design-build, alternative bidding by its policy. However, delivery systems should be determined through considering physical projects characteristics, owner's goals, external factors, etc, rather than government' policy. Therefore, the purpose of this research is to propose objective delivery system selection criteria and delivery system selection model, which help owners to select the suitable delivery system through quantitative and reasonable manner.

This study aims to investigate the characteristics of Lee Kyo-Won's landscape architecture and add to the literature in this field. Also, the current status of and issues in landscape design will be dealt with through the lens of the individual landscape architect's worts. By adopting a critical analysis, this study will look closely into the background of his career and ideas regarding landscape design. The inherent nature of his coherent style in landscape design will be listed as follows: total design, design-build systems, experimentation with new kinds of plants and materials, and the pursuit of minimalism. His design domain covers various elements such as paving, street lamps, and clock towers, among others. He was often involved in managing outdoor sculpture and he also provided the total packaging of the design-build systems for most of his landscape projects. These are the main reasons why his landscape works can maintain their high end quality; through his craftsmanship, a fine quality of detail was achieved in his landscape design. This tell us the possible options that can be adopted such as landscape architectural design management or landscape architectural turn-key systems, which differ from the prevailing dual system between design and construction. However, his own particular system can not be replicated in ordinary situations because contemporary practices require us to coordinate the various stakeholders concerned in the decision-making process of the design. In general, it is fair to say that we can give him the credit for enhancing the status of landscape design as an independent, specialized field.

In the 21st century, medical facility projects are required to operate appropriate digital technologies as the development of technology and the interests of various participants become more complex. In order for architects to successfully lead negotiations among various stakeholder groups, it is necessary to plan for effective communication through appropriate design reflecting their opinions and coordination of conflicts. For this purpose, building information modeling (BIM), which is a method of designing based on knowledge information related to medical facilities in the building database, can respond to change of order promptly and minimizes the occurrence of design errors can do. Recently, BIM technology and cloud computing technology in ICT have been combined and research on cloud BIM has been actively carried out. The use of cloud computing technology in BIM-based healthcare facility projects can effectively support decision making among project participants and has the advantage of sharing and collaborating on various forms of information generated during the design process, regardless of location and time. Therefore, the purpose of this study is to build of system that can support the design of medical facility using cloud computing technology in BIM.

In the delivery systems for public construction works, design-build methods such as turn-key and alternative have contributed to improving the quality of structures and developing the construction technology. However, it is pointed out that construction based on a design-build method is likely to waste a budget due to its higher contract price than construction based on a design-bid-build method. Other issues such as contract monopoly, bid rigging and deliberation irregularity in design-build. Since there are not much works have been accomplished to comparatively analyze the actual performance and effect based on delivery methods, discussing and judging the performance and effect of each deliver method with limited information could lead to an error. Thus, this study by extensively investigates the actual project cost data, ranging from contract price to the construction cost of the public construction works and comparatively analyzed the characteristics of each delivery method about cost structure and fluctuation trend. This work is expected to assist stake-holders in properly understanding delivery systems for public construction works and promoting their efficient management.

Many Korean construction companies have been performing a variety of overseas construction projects since the 1970s. It is unfortunate that in many cases they have had to suffer big losses caused by errors and defects in the design and construction of the projects. In the author's opinion, however, there were losses that could have been avoided if they had understood better the feature and content of the particular construction contract. Few lawyers and scholars in Korea have been interested in the research and study of international construction contracts. This is mainly because they do not have access to practical sources outside of Korea for them to research and study since the contracts undertaken have been dealt with by law firms in other jurisdictions to which the disputes apply. This article is aiming primarily at the introduction of the issues which the practitioners are likely to confront in the process of reviewing and performing the international construction contract. In some cases solutions are sought about these issues based upon the FIDIC standard terms and conditions, the actual experience of practice, and UNIDROIT Principles, etc. It is reasonable to say that all the issues related to the international construction contract cannot be covered in a short article like this. The author wishes this article could induce subsequent studies on international construction contracts for further research. It has to be noted that from time to time Korean construction practices have been compared to the international ones for better understanding. This article mostly includes cases where the Korean construction companies go overseas for their projects, while there are some cases where foreign developers and financial investors participated in domestic projects in which international construction contracts forms were adopted. A few precedent domestic writings about international construction contracts seems to lack emphasis on the points that there are several standard construction contract forms and that they are different. The differences are mainly in accordance with who bears the design responsibility, how the owner has to make progress payments to the contractor and who the funding source for the project is. This article tries to make it clear that there are significant differences between the standard contract forms, e.g. a simple construction form, a design-build form and an EPC/turnkey form of contract. Again, the author hopes that this article can arouse the interest in the international construction contracts from both academic and practical fields, so that many subsequent advanced articles can help our construction industry become much more competitive in the world through awareness of the methods of procurement and administration of the contracts.

Two main features of the recent building project are the enlargement of the size and the technological complexity. Due to these features, the number or the size of organizations participating in building project is also increasing and the relationships between the organizations are becoming more interdependent than ever. Owing to these features, some delays or errors in the decision-making process in the phase of planning of a building project may influence many subjects related to the project. The most important factor for a successful project is to arbitrate confrontations and build cooperative relationships between parties who have different interests with one another in the project. Efforts were made to find out general features of building project and the features in the phase of planning in order to set a direction of this research. To solve problems in the phase of planning, the concept of 'cooperative design', which means that different features and interests of various organizations should be reflected from the phase of planning, was introduced. By introducing cooperative design in building projects, more rapid and objective decision-makings are possible.

Turnkey contract system is an effective ordering system for the organizations that technical engineers are insufficient in their construction projects. It is possible to reduce project duration and to improve project Quality in an integrated contract system between design and construction. However, owners can have a difficulty caused from unitary responsibility system. This study analyzes present situation and problems of turnkey contract system in our country. The results includes various methods for improving the system based on the analysis of bid price nd selection procedure.
