Purpose: In the Korean railway infrastructure process, contractors and operators are involved at a later stage, which results in significant inefficiency. This study examines the benefits of early stakeholder involvement in Korean railway infrastructure projects and provides practical guidelines. Design, data and methodology: Literatures and foreign cases are analyzed. Building on the new product development model, we derive propositions explaining the relationship between early stakeholder involvement and the performance of Korean railway infrastructure project. Results: Major propositions include that early involvement of contractor has a positive effect on the project performance by shortening the infrastructure construction period and that early involvement of railway operator has a positive effect on the project performance by improving the effectiveness of railway infrastructure. Four requirements for the success of early stakeholder involvement are addressed. Conclusions: This study suggests that early stakeholder involvement shortens the construction period and improves railway infrastructure effectiveness. Academic contribution is to present the framework on railway infrastructure projects as holistic interactions among stakeholders. Practical contribution is to provide railway policy makers and other business practitioners with policy guidelines to improve railway infrastructure project process and to recommend an open access to relevant data.

Transportation infrastructure is critical to economic growth of a country such as China. Careful evaluation of investments in traffic infrastructure projects is therefore pertinent. As traditional evaluation methods do not consider the uncertainty of future cash flows and mobility during project execution, the real option approach is gradually gaining recognition in the context of valuing construction and infrastructure projects. However, many of the cases only evaluate individual options separately although multiple options often exist in a typical large infrastructure project. Using a highway project in China as a case study, this paper first evaluates a deferment option and a growth option embedded in the project. Subsequently, the values are combined using the fuzzy analytical hierarchy process. It is found that the combined value is less than the sum of the two option values. This finding is consistent with the theoretical observations given in past real option literature despite the use of a different approach.

In this study, the Inter-Korea Fisheries Cooperation Project was divided into four categories: North Korea's Fisheries Infrastructure Development Project, Fisheries Cooperation Project, Human Exchange Project, and North Korea Fisheries Investment Project. First, North Korea's fisheries infrastructure development projects include North Korea's fisheries resource research project, it's fisheries resource development project, and joint enforcement on illegal operation of Chinese ships. Second, fisheries cooperation projects include the operation of the North-South common fish area in the West Sea, the fishing project in North Korea's East sea, and the import of North Korean seafood. Third, human exchange projects include training of aquaculture technicians in North Korea, technology transfer and training of fishing vessels, and boarding of North Korea's fisherman in Korean fishing vessels. Fourth, North Korea's fisheries investment projects include aquaculture facilities and aquaculture feed support, aquatic product processing facilities and technology transfer, and fishery equipment support. However, as international sanctions are maintained in the international community to North Korea, Inter-Korea Fisheries cooperation, however, should be promoted according to the level of easing of international sanctions as international sanctions are maintained in the international community to North Korea. First, North Korea's fisheries resource research project, North Korea's fisheries resource creation project, joint enforcement on illegal operation of Chinese ships, and operation of the common fish area in the West Sea can be promoted if international sanctions are maintained at present, promote North Korea's fisheries resource research project. Second, boarding of North Korean's fisherman in Korean fishing vessels, conducting the fishing project in North Korea's East sea, and importing North Korean seafood can be aided if commercial transactions are possible with North Korea. Third, South Korea will support aquaculture facilities and aquatic feed, fisheries processing facilities and technology transfer, fishery equipment support, training of fisheries and aquaculture technicians, fishery fishing technology transfer, and training of fisherman when a comprehensive economic cooperation project is possible with North Korea.

The governmental attitude toward private investment and financing for infrastructure projects has changed from the initial prohibition to the current encouragement in China, which has been embodied in the legal documents and administrative process. However, the problem of identification, bidding, and approval procedure for privately financed infrastructure projects has been observed in policies and administrative measures promulgated by different or even the same government branches, which is prohibitive factors for smooth project implementation. After analysis of the identification, bidding, and approval process of infrastructure projects, the authors proposed a simplified and alternative procedure and clarified the key points of relevant project documents.

After participation in the Colombo Plan in 1954, Japan has provided Official Development Assistance (ODA) to 185 countries and areas, and the accumulated amount of Japan's ODA is approximately US$ 221 billion for 50 years. Japan is the second largest ODA donor country in the world now. The country is contributing to the peace and development of the international community. However, the recipient government and the parties concerned are not always satisfied with the Japan's ODA system.. Especially the grant aid system is strongly based on the domestic public work system. This paper analyzes the problems and figures out solutions from the viewpoint of donor and the participant.

This paper presents an evaluation of feasibility studies conducted to justify investments in infrastructure projects. An analysis of a previous feasibility study for a highway construction project is presented in this paper with an emphasis on the estimates and forecasts presented in that study in order to weigh expected benefits from the project against expected costs. The forecasted numbers are compared with actual data collected during the operation phase about the usage of the facility. The comparison reveals a huge difference between estimated numbers and actual numbers. Based on the lessons learned from the analyzed case study, recommendations are presented to improve feasibility studies for infrastructure projects including: peer review of feasibility studies; before-and-after feasibility studies; and defined scope and methodology for feasibility studies. Decision makers are advised to take outcomes of feasibility studies for infrastructure projects with extreme caution as some studies may provide erroneous and misleading input to their decisions regarding investment in infrastructure projects.

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.

In this paper, a survey related to excavation construction activities among national and international construction companies was conducted to evaluate site productivity in construction industry. To analyze the respective productivity levels of each construction company, a benchmarking measures analysis that featured calculations of the performance ratio (PR) and performance management index (PMI) was performed. As a result of these analyses, it has been found that the work performed by local companies was marked by lower productivity and that of international companies was characterized by good productivity. Further analysis of construction workforce resources P% revealed that a construction company's productivity is largely dependent on production capacity and consumption resources, which means that the retention of skilled workers and utilization of high-quality resources yields the highest level of productivity. These results suggest that for a local construction company to be competitive in the construction work market, it must retrain skilled craftspeople, foremen, engineers, and project managers, and strengthen its building capability by leveraging new equipment and technologies.

With Beijing's success in bidding for the 2008 Olympic Games, the increasing demand for infrastructure development and reduced public sector funding capacity has created a significant funding gap which calls for alternative project delivery methods such as Public-Private Partnership (PPP). Although the exploration of infrastructure projects using PPP model have been practiced since the late 80s, the $560 million National Stadium which served as the main venue for the Olympic Games is the first stadium project in China to be delivered under PPP operation. The project is generally considered successful despite the concession transfer in 2009 with concern of better serving the public interest. Compared to other infrastructure projects such as transportation, waste management and water management, the development of major sports facilities for mega-sports events with PPP has its own unique features and is subject to different major risks. This research identifies and analyzes critical risks in the implementation of PPP in major sports facility development through case study of the National Stadium project. A questionnaire survey and several interviews are conducted to solicit expert opinions from experienced practitioners. The purpose is to provide additional insights in risk management strategies and opportunities in China's PPP implementations in major sports facilities for policy makers and private sectors involved with investment decisions in future similar infrastructure development.
