Abstract

Purpose

This paper aims to help understand how adopting risk allocation criteria impacts the delivery of public–private partnership (PPP) mass housing in Nigeria with the view of promoting the adoption of PPP housing scheme in Nigeria.

Design/methodology/approach

The research design adopts the census sampling approach by using well-structured questionnaires distributed to stakeholders involved in PPP-procured mass housing projects, i.e. consultants, in-house professionals, contractors and the organized private sector, registered with PPP departments in the Federal Capital Territory Development Authority, Abuja, Nigeria. Sixty-three risk factors, nine risk allocation criteria and nine project delivery indices were submitted for the respondents to rank on a Likert scale of 7. Two hypotheses were formulated to test whether the risk allocation criteria impacted PPP mass housing delivery or otherwise. The study adopts partial least square-structural equation modeling to model the effect of risk on risk allocation criteria on project delivery indices and risk severity.

Findings

The finding shows that project risk allocation criteria have less effect on project delivery indices than on risk severity. The study concludes that risk allocation principles do not directly affect the delivery of PPP-procured mass housing projects. This is evident by the path coefficient of 0.724 values, which is not statistically significant at a 5% alpha protection value. The study concludes that allocating critical risk factors influences the performance of PPP-procured mass housing projects, as the path coefficient of 0.360 is also not significantly far from 0 and at a 5% alpha protection value.

Originality/value

The study is one of the recent studies conducted in PPP-procured mass housing projects in Nigeria owing to the novelty of procurement option in the sector. It highlights the risk factors that can jeopardize the PPP-procured mass housing project objectives. The study is of immense value to PPP actors in the sector by providing the necessary information required to formulate risk response methods to minimize the impact of the risk factors in PPP mass housing projects.

Abstract

Purpose

With the increasing complexity of public–private partnership (PPP) projects, the amount of data generated during the construction process is massive. This paper aims to develop a new information management method to cope with the risk problems involved in dealing with such data, based on domain ontologies of the construction industry, to help manage PPP risks, share and reuse risk knowledge.

Design/methodology/approach

Risk knowledge concepts are acquired and summarized through PPP failure cases and an extensive literature review to establish a domain framework for risk knowledge using ontology technology to help manage PPP risks.

Findings

The results indicate that the risk ontology is capable of capturing key concepts and relationships involved in managing PPP risks and can be used to facilitate knowledge reuse and storage beneficial to risk management.

Research limitations/implications

The classes in the risk knowledge ontology model constructed in this research do not yet cover all the information in PPP project risks and need to be further extended. Moreover, only the framework and basic methods needed are developed, while the construction of a working ontology model and the relationship between implicit and explicit knowledge is a complicated process that requires repeated modifications and evaluations before it can be implemented.

Practical implications

The ontology provides a basis for turning PPP risk information into risk knowledge to allow the effective sharing and communication of project risks between different project stakeholders. It can also have the potential to help reduce the dependence on subjectivity by mining, using and storing tacit knowledge in the risk management process.

Originality/value

The apparent suitability of the nine classes of PPP risk knowledge (project model, risk type, risk occurrence stage, risk source, risk consequence, risk likelihood, risk carrier, risk management measures and risk case) is identified, and the proposed construction method and steps for a complete domain ontology for PPP risk management are unique. A combination of criteria- and task-based evaluations is also developed for assessing the PPP risk ontology for the first time.

Abstract

Purpose

This research investigates the financial viability risk factors that threaten the private investor's economic scheme in the public private partnership (PPP) wastewater treatment plant (WWTP) projects in Egypt. The aims of this study are to: (1) illustrate and cluster the financial viability risk factors in accordance with the PPP WWTP projects' nature, (2) assess the risk factors' criticality degrees according to their severity and frequency levels of the financial viability, and (3) pinpoint the suited allocation of the financial viability risk factors between the public and private parties.

Design/methodology/approach

Relying on the previous analysts' endeavors, the questionnaire method, the fuzzy synthetic evaluation approach and the hypothetical normal distribution curve model; the severity, frequency, criticality and allocation preference of 32 financial viability risk factors were assessed from 12 Egyptian PPP experts.

Findings

The data analysis yielded that foreign exchange risk, currency risk/inflation, license risk, construction cost-overrun and late site handover are the key factors in arising the financial viability risk issue in the PPP WWTP projects. Considering the discussion of these key risks, the study summarized that the financial viability's key risk factors are notably be affected by the economic, political and administrative circumstances of the host county. Additionally, the inflation lesion was found to be the core reason of most of the key risk factors.

Originality/value

This research originality stems from its contribution to address the gab in the PPP risk assessment literature of the concessionaire's financial viability in the WWTP projects in a country of developing economy as Egypt. This, first, enriches the scholarly based knowledge of the PPP projects' risk analysts of the developing countries. Accordingly, it moves the current PPP risk assessment research further to deeply apprehend these markets' risks. Second, it equips the policymakers in the public and private sectors of such projects with a map that clarifies their assigned risk factors and the responsibilities that each party should bear to generate a mutual stable investment environment for achieving their aims successfully. This, indeed, paves the way for more private investments to be involved in the developing markets' PPP projects with a profitable satisfactory level for the private concessionaire. In the same vein, more WWTP projects, which are highly needed for the public sector and its people, are executed.

Abstract

Purpose

Early termination of public–private partnerships (PPPs) in China is caused by various risk factors, resulting in significant losses. This study aimed to clarify the key factors and identify the causal relationships among these factors.

Design/methodology/approach

Social network analysis (SNA) was used to analyze 37 risk factors that were summarized from 97 early terminated PPP cases and to identify the relationships among these key risk factors. Interpretive structural modeling (ISM) was conducted to explore the causal relationships. Data were collected from case documents, questionnaires and interviews.

Findings

A total of 17 key risk factors were identified and distributed in a hierarchical structure with six tiers. Among these key risk factors, the root causes affecting the early termination of PPP projects were government oversight in decision-making, local government transition, policy and law changes and force majeure. The direct cause was insufficient returns. Furthermore, local government and private sector defaults were essential mediating factors. Local government transition and the low willingness of the private sector were highlighted as potential key risks.

Research limitations/implications

The cases and experts were all from China, and outcomes in other countries or cultures may differ from those of this study. Therefore, further studies are required.

Practical implications

This research provides knowledge regarding the key risk factors leading to the early termination of PPP projects and guidance on avoiding these factors and blocking the factors' transmission in the project lifecycle.

Originality/value

This study contributes to the knowledge of risk management by emphasizing the importance of local government transition, the low willingness of the private sector and project cooperation and operation, whose significance is ignored in the existing literature. The proposed ISM clarifies the role of risk factors in causing early termination and explains their transmission patterns.

Abstract

Purpose

Many waste-to-energy (WTE) plants are constructed and operated using the public-private partnership (PPP) mode in China. However, risk events of PPP WTE incineration projects sometimes occur. This study aims to clarify the relationship of risks in China's PPP WTE incineration projects and identify the key risks accordingly and risk transmission paths.

Design/methodology/approach

A risk list of PPP WTE incineration projects was obtained based on literature analysis. Moreover, a hybrid approach combining fuzzy sets, decision-making trial and evaluation laboratory (DEMATEL) and interpretive structural modeling (ISM) was developed to analyze the causality of risks, explore critical risks and reveal the risk transmission paths. The quantitative analysis process was implemented in MATLAB.

Findings

The results show that government decision-making risk, government credit risk, government supervision behavior risk, legal and policy risk, revenue and cost risk and management capacity risk are the critical risks of PPP WTE incineration projects in China. These critical risks are at different levels in the risk hierarchy and often trigger other risks.

Originality/value

Currently, there is a lack of exploration on the interaction between the risks of PPP WTE incineration projects. This study fills this gap by examining the key risks and risk transfer pathways of PPP WTE incineration projects from the perspective of risk interactions. The findings can help the public and private sectors to systematically understand the risks in PPP WTE incineration projects, thus enabling them to identify the risks that need to be focused on when making decisions and to optimize risk prevention strategies. The proposed hybrid approach can offer methodological ideas for risk analysis of other types of PPP projects.

Abstract

Purpose

Construction organisations cannot underestimate the improvement in public–private partnership (PPP) projects’ implementation. At the same time, construction organisations cannot overlook the risk arising from engaging in PPP construction projects. Hence, this study aims to establish the influence of risk resource management (RRM) in managing PPP risk in the construction industry in Ghana.

Design/methodology/approach

The researchers adopted qualitative and quantitative research methods to achieve the aim of the study, in which Delphi questions and a close-ended questionnaire were developed. A total of 650 construction specialists, including procurement officers, consultants, project managers, quantity surveyors, site engineers and planning officers were chosen using random and purposive sampling techniques. Recovered data were analysed using descriptive statistics and confirmatory factor analysis (CFA). The CFA maximum likelihood estimation extractor compresses 19 variables into 3 pattern matrices.

Findings

The results of the study revealed three factors that measure RRM in Ghana’s PPP construction industry, including financial resource management which was influenced by communicating the budget to project team members and project partners understanding the budget, and material resource management which was influenced by the provision of materials transportation and provision of delivery programs and labour resource management which was impacted by a commitment to pay social security and taxes and provision of good salaries, to address RRM in PPP construction organisations.

Research limitations/implications

To incessantly improve the PPP risk management (RM) in construction through RRM, there should be a strong liaison between the universities, government agencies and the construction industry, and such collaboration will assist the industry to obtain first-hand information regarding the study findings and how they can be implemented to help the development of RM in the construction industry. This study is limited to Ghana and CFA and further study should explore structural equation model to determine the structure and measurement model of the risk resource variables.

Originality/value

The study may be valuable to industry stakeholders looking for new approaches to improve RM in their construction activities, particularly in PPP projects. Also, to assist reduce PPP risk, construction companies should use RRM in their organisations.

Abstract

Purpose

The purpose of this paper is to empirically compare the risk factors in public-private partnership (PPP) projects in developing and developed countries, represented by Ghana and Hong Kong, respectively.

Design/methodology/approach

A structured questionnaire survey was conducted with PPP practitioners in Ghana and Hong Kong. In total, 103 valid responses were received for analysis. Kendall’s coefficient of concordance and mean ranking were used for data analysis.

Findings

The results show that respondents from Ghana ranked country risk factors higher, whereas their Hong Kong counterparts ranked project-specific risks higher. The top five significant risks in Ghana are corruption, inflation rate fluctuation, exchange rate fluctuation, delay in project completion and interest rate fluctuation. In Hong Kong, the top five significant risk factors are delay in land acquisition, operational cost overruns, construction cost overruns, delay in project completion and political interference.

Originality/value

The results of the study inform international investors of the appropriate risk mitigation measures and preventive actions to use when engaging in PPP arrangements in any part of the world. Further, governments who are yet to use the PPP concept would be informed of the prevailing risk factors in other neighbouring countries (i.e. developing or developed countries).

Abstract

Purpose

The purpose of this paper is to focus on the challenges faced by the public and private sectors in developing output specifications for Australian public private partnership (PPP) projects. In particular, this study aims to examine how the stakeholders (including facilities managers) should cater for future changes in output specifications and make them flexible enough to meet the evolving project objectives.

Design/methodology/approach

The research is based on 19 semi‐structured interviews with key stakeholders from the public and private sectors in three States of Australia where PPP procurement has been used, including New South Wales (NSW), Queensland and Victoria. The results are triangulated with relevant literature for supports and contrasts.

Findings

For PPP projects, a good set of output specifications is conducive to the achievement of value for money, innovation, risk transfer, whole life asset performance through a clear abatement regime and an effective linkage of performance criteria to the payment mechanism. For existing specifications, it was found that too many and complex KPIs were specified, which were difficult to monitor, measure and implement by the client. Very prescriptive specifications hindered innovations and did not allow appropriate risk allocation. Further, the research study suggests that after the global financial crises, the private sector had less appetite to take the patronage risks in road and rail PPP projects. To mitigate these pitfalls, it is imperative that output specifications need to be aligned with the type of PPP projects they represent; in particular foreseeable changes should be addressed by some pre‐agreed framework to facilitate negotiation.

Originality/value

The significant contribution of this research is the identification of the common issues faced in drafting output specifications for Australian PPP projects. Stakeholders of future PPP projects should find the lessons useful for achieving value for money and appropriate risk transfer, stating the user requirements through clear and concise output specifications rather than input or prescriptive specifications in procuring social and economical PPP projects. Their relationships with facilities management are highlighted.
