Public private partnership (PPP) procurement was introduced into Singapore in 2003, and 10 PPP projects was successfully completed and have been in operation. The objective of this study is to identify the critical risk factors and risk allocation preferences for PPP projects in Singapore. To achieve this objective, a comprehensive literature review was carried out and 42 risks were identified and grouped into three meta levels, i.e. macro, meso and micro levels. The questionnaire survey produced 48 completed questionnaires from 48 different contractors. The survey results indicated that 23 risk factors had significantly high criticalities and that four macro-level risks, four meso-level risks and two micro-level risks were among the top 10 risk ranking. "Lack of support from government", "availability of finance" and "construction time delay" were perceived as the top three critical risks. Also, the result implied that micro-level risks had a higher criticality mean score than macro-level and meso-level risks. The findings of this study help both public and private sectors to better understand the risks and their allocation in PPP projects, providing valuable information for organizations that intend to participate in PPP projects in Singapore.

Procurement system of public construction projects in Japan is changing with diversity in rapid pace. The quality assurance and risk management of construction projects should be more certain as the projects are turning into larger scale and more complexed. The clients in the public sector will want to make the relation of responsibility among the client, the designer (architects and engineers), and contractor clearer in terms of role and risk. Public-Private Partnership (PPP) is one of the methods for collaboration of the public sector and the private sector in public construction projects where the public utilizes the ability and suggestion of the private. Private Finance Initiative (PFI), Design-Build-Operate (DBO), market testing, designated manager system, outsourcing of tasks in local governments are well-known as examples of PPP in Japan. Indeed, there is an obvious trend that Design-Build (DB) is adopted in public construction projects in many countries including Japan. In this paper, the public construction projects in various procurement systems are surveyed and analyzed. They are not limited within the traditional procurement, Design-bid-Build, a separate order system of design and construction. Design-Build or PFI are adopted. In particular, contract by wide range including maintenance of equipment can be found. On the other hand, modification from originally typical PFI is taking place, such as concept design and project finance are removed from the roles and the tasks of the special purpose company (SPC) in PFI. Standard roles and tasks in a construction project are modeled in this paper.

Public infrastructure is crucial to promote and sustain a sustainable economic growth and a health community. A large amount of capital investment is generally required in infrastructure projects that motivate the involvement of the private sector in the delivery process. Various relationship-based procurement methods have been attempted to maximize value-for-money. In this paper, the problems and challenges that relationship-based procurement methods have been facing are explored. A particular focus is placed on the challenges for the public-private partnership (PPP) model. Possible strategies for adapting the PPP models in the post-Global Financial Crisis era are proposed and discussed. In addition, the challenges facing alliancing, which is one of the other important relationship-based procurement methods, are also examined. Views on infrastructure procurement in the future were sought from industry professionals via interviews and are reported in this paper as well.

베트남의 경제 성장률과 도시인구는 꾸준히 증가함에 따라 베트남의 인프라 개발 건설 시장 규모는 더욱 커질 전망이다. 그러나 인프라 개발을 위한 베트남 정부는 재정 및 행정 능력의 한계로 이러한 문제를 해결하기 위한 방안으로 PPP를 채택하고 있다. PPP는 10년 이상 지속되는 장기 사업으로 사업 실패 시 장기적 큰 피해가 될 수 있어 위험관리가 매우 중요하다. 본 연구에서는 리스크 관리에 대한 리스크 요인의 영향과 관리정도 분석에 SOM분석을 제안한다. SOM분석 방법은 시각화 분석으로, 각 리스크 요인의 색상 패턴을 통해 상관 분석이 가능하다. 본 연구는 SOM을 활용하여 베트남 PPP 사업의 위험요인의 우선순위를 결정하고자 한다.

This paper stems from information accumulated from extensive literature review, a pilot study and a formal interview for an ongoing research on housing privatization implemented by the government-linked companies in Malaysia. Through extensive literature review, issues pertaining to housing privatisation were identified. Expectations of public sector, outcome of housing privatisation and factors influencing such outcome have also been tentatively confirmed through pilot study and an ongoing postal survey. A formal interview with a project director of independent Public-private partnerships (PPP) organization in UK has also inspired some useful lessons for the local housing industry. Different modalities of PPP from various countries show that while housing privatization pose several problems, mitigating them is possible through appropriate strategies.

사회기반시설은 국가 경쟁력 지표로써, 전통적으로 정부의 SOC 재정으로 건설되어 왔다. 그러나 SOC 예산 축소에도 불구하고 사회기반시설의 확충 요구를 해결하기 위해 민간투자사업제도가 도입되었으며, 이 중 도로사업의 비중이 높다. 본 연구는 기 제안된 도로사업 사업계획서의 운영관리비와 사업계획서와 연계되는 재무모델의 운영관리비 항목을 분석하고, 도로사업의 특성을 반영하기 위해 한국도로공사의 사업비 항목과 운영관리 업무를 분석하였다. 분석 결과를 통해 분류체계를 마련하여 비용산정 기준을 마련하는 것이 요구된다. 또한 업무의 효율성을 고려하여 기존의 업무 도구를 웹기반으로 통합하여 하나의 시스템으로 개발하는 것을 제안하였다. 이를 통해 민간투자사업의 전체적인 사업성 확보에 기여하고, 수익성을 기반으로 하는 사회기반시설의 확충에 기여할 것으로 기대된다.

민간투자사업에 대한 부정적인 시각으로 인해 민간투자사업 시장은 축소되었으나, 최근 국내 재정사업의 축소로 인해 민간투자사업에 대한 필요성이 다시금 제기되고 있다. 민간투자사업은 건설사, special purpose company (SPC), 재무투자자 등 다양한 참여자들 간의 이해관계가 복잡하여 사업의 성과를 판단하기 위해서는 참여자 간 관점 차이에 대한 고려가 필요하나, 기존의 연구는 재무적 관점의 수익성 예측, 또는 리스크 식별을 통한 수익성 예측을 중심으로 수행되었다. 이러한 점을 고려하여 본 연구에서는 민간투자사업 주요 참여자별 특성에 따른 민간투자사업 성과예측 모델을 개발하였다. 이를 위해 첫째, 다양한 분야의 문헌고찰을 통해 민간투자사업의 조직구조를 분석하였으며, 건설사, SPC, 재무투자자의 관점에서 민간투자사업 수익성 영향요인을 도출하였다. 둘째, 도출된 수익성 영향인자들을 바탕으로 민간투자사업 관련 전문가 설문조사 및 인터뷰를 실시하였다. 셋째, 구조방정식 모델(structural equation model)을 통해 민간투자사업의 구성개념들 간에 직접효과와 간접효과를 분석하여 민간투자사업의 수익성 및 수익안정성 측면에서의 성과를 거시적으로 이해할 수 있는 모델을 개발하였다. 넷째, 모델을 통해 도출된 결과를 바탕으로 민간투자사업의 재도약을 위한 발전방안을 제시하였다. 향후 본 모델을 통해 수익성과 수익안정성 측면에서 건설사, 재무투자자, SPC 운영사의 사업성과 예측이 가능하며, 이에 따른 대응전략을 모색하는데 활용 가능할 것으로 기대된다.

Infrastructure procurement has been a major engagement route between China and Africa. This contributes immensely to the gradual infrastructure development seen on the continent. However, maturing discourse purports that these infrastructure collaborations lack intentionality in the continuous development of strategic guidelines and policies for effective implementation despite their uniqueness and criticality. This study proposes that an efficient approach to policy recommendations is through the political and economic analysis (PEA) of these partnerships using public-private partnership (PPP) optics. Unquestionably, these partnerships are representative of the concept of diplomatic transnational public-private partnership (DT-PPP) where infrastructure is procured through the collaboration of public (African governments) and private sector (Chinese state-owned corporations) who provide the managerial, financial, and technical resources for the project implementation. Given the quest for sustainable win-win, this study identifies strategies towards the realization of win-win in the implementation (i.e enablers of win-win) such that fairness and co-benefit, as well as interests, will be achieved. Thus, based on the PEA framework, case scenarios from Ghana and Nigeria using expert interviews identify the criticalities and best practices for the realization of these enablers at the development phase. Findings indicate more effort is required of the public sector (African host countries) in terms of people, structure/institutions, and the implementation processes. Recommendations include improvement of environmental management structures, contract administration procedures, external stakeholders/local community engagement mechanisms, knowledge and technology transfer procedures, and sector-based project operation and maintenance culture and systems. Additionally, actors must have emotional intelligence, good problem-solving abilities, and overall ensure cordial relationships for continued bilateral cooperation.

Australia has joined many governments to adopt public-private partnership (PPP) as a major strategy for procuring infrastructure for decades. However, failures have occurred although the market has been considered to be a mature and sophisticated one. Failures have typically been traced back to inappropriate economic evaluation and a lack of value-for-money. In particular, a literature review has identified that there was no holistic consideration on the evaluation of procurement transactions of PPP projects. The transaction costs of PPPs were not handled properly. In this paper, theories of transaction cost economics are proposed for the purpose of such a holistic institutional economic evaluation. These theories are analysed in order to identify potential critical success factors for a strategic infrastructure procurement framework. The potential critical success factors are identified and grouped into a number of categories that match the theories of transaction cost economics. These categories include (1) Asset Specificity, (2) Organizational Capability, (3) Transaction Frequency, (4) Behavioural Uncertainty, and (5) Environmental Uncertainty. These potential critical success factors may be subject to an empirical test in the future. The proposed framework will offer decision makers with an insight into project life cycle economic outcomes needed to successfully deliver PPPs.

India has accorded a high priority to road infrastructure development through Public-Private Partnership (PPP) and it has set a high target for investment inflows. Yet, it is widely held that road/highway infrastructure has not been developing at required pace and that the road infrastructure projects under PPP have been suffering from several hurdles and delays, thereby affecting project success/failure. This paper is an attempt to analyze the critical success/failure factors of road infrastructure projects under PPP in India. A questionnaire survey was conducted among a sample of the stakeholders of road infrastructure projects to identify the critical success/failure factors during all four major project stages using different approaches. Initially, the critical factors were identified through ranking based on the average/mean score. Later, the conventional RII score was used to identify the critical success/failure factors. Finally, the critical success/failure factors were also identified based on the stakeholder-wise ranking of the factors and their convergence. The assessment revealed that there was a greater convergence across the different methods and also that there was greater consensus among project stakeholder on the critical success/failure factors of road PPP projects.
