Indicators-based framework has been developed for the sustainability assessment of infrastructure projects but this framework has limitations in quantifying the qualitative parameters. The top-down approach that utilizes principles to assess the sustainability of infrastructure projects has the ability to consider qualitative parameters. The research on the development of principles-based approach is however limited and, in fact, the study on the development of principles to assess the sustainability of public–private partnerships (PPPs) infrastructure projects is in a nascent stage. The purpose of this study is the development of an empirical framework of guiding principles that will facilitate the assessment of PPPs from sustainability perspective. The study has used a grounded theory qualitative approach by using interviews and literature as primary and secondary data sources, respectively, to develop the framework of guiding principles to achieve goals of sustainable infrastructure development through PPPs. The framework comprises 18 guiding principles, which will act as guidelines to facilitate promotion of sustainable practices throughout the life cycle of PPP project so that sustainability goals can be accomplished. The guiding principles could be used as the qualitative parameters for public and private sector to assess the sustainability of PPP infrastructure projects. This chapter presents critical insights on principle-based approach for sustainability assessment of PPP projects, which has not been the focus in the majority of earlier studies.

In successfully meeting city and metropolitan growth, sustainable development is compulsory. Sustainability is a must-focus for any project, particularly for large and mega rail infrastructure. This paper aims to investigate to what degree social, environmental and economic factors influence the government when planning sustainable rail infrastructure projects. To respond to such a matter, this paper focuses on two Australian mega-rail projects: the South West Rail Link (SWRL) and the Mernda Rail Extension (MRE).

As the basis of an experimental evaluation framework strengths, weaknesses, opportunities and threats (SWOT) and factor analysis were used. These two methods were specifically selected as comparative tools for SWRL and SWRL projects, to measure their overall sustainability effect.

Using factor analysis, in the MRE, the factors of network capacity, accessibility, employment and urban planning were seen frequently throughout the case study. However, politics and economic growth had lower frequencies throughout this case study. This difference between the high-weighted factors is likely a key element that determined the SWRL to be more sustainable than the MRE. The SWOT analysis showed the strengths the MRE had over the SWRL such as resource use and waste management, and natural habitat preservation. These two analyses have shown that overall, calculating the sustainability levels of a project can be subjective, based on the conditions surrounding various analysis techniques.

This paper first introduces SWRL and MRE projects followed by a discussion about their overall sustainable development. Both projects go beyond the traditional megaprojects' goal of improving economic growth by developing and enhancing infrastructure. Globally, for such projects, sustainability measures are now considered alongside the goal of economic growth. Second, SWOT and factor analysis are undertaken to further evaluate the complexity of such projects. This includes their overall sustainable development vision alignment with environmental, economic and social factors.

This chapter discusses the opportunity of Islamic project financing implementation for public infrastructure development in Indonesia.

This chapter, firstly, reviewed existing literature on Islamic finance to explore the applicability of Islamic financing in infrastructure development. Interviews were conducted as the first stage of Delphi method approach. This was then followed by reviewing Indonesia’s government policies and regulations in infrastructure industry and Islamic financing.

This chapter enlightens the implementation of Islamic financing on infrastructure project financing in Indonesia. The findings indicate that the government policies and regulations on both infrastructure investment and Islamic financing support the implementation of Islamic project financing, whereas, an improvement is still needed in order to overarch infrastructure business and Islamic financing investment.

Financing framework development for Indonesia infrastructure projects.

The result reported comprises the preliminary study of Islamic project paper written based on published research papers and interviews. Furthermore, the data collected for the study are limited to the case of Indonesian infrastructure projects.

Islamic financing in Indonesia infrastructure projects development has not been optimally implemented. Therefore, this chapter serves as a catalyst to explore alternative financial scheme such as Islamic financing for infrastructure development.

This chapter highlights possibilities and obstacles in applying Islamic scheme to infrastructure project financing. This provides a framework to analyse the steps to implement Islamic financing successfully in infrastructure development.

Recent United Nations Climate Change Conferences recognise extreme climate change of heatwaves, floods and droughts as threatening risks to the resilience and success of public–private partnership (PPP) infrastructure projects. Such conferences together with available project reports and empirical studies recommend project managers and practitioners to adopt smart technologies and develop robust measures to tackle climate risk exposure. Comparatively, artificial intelligence (AI) risk management tools are better to mitigate climate risk, but it has been inadequately explored in the PPP sector. Thus, this study aims to explore the tools and roles of AI in climate risk management of PPP infrastructure projects.

Systematically, this study compiles and analyses 36 peer-reviewed journal articles sourced from Scopus, Web of Science, Google Scholar and PubMed.

The results demonstrate deep learning, building information modelling, robotic automations, remote sensors and fuzzy logic as major key AI-based risk models (tools) for PPP infrastructures. The roles of AI in climate risk management of PPPs include risk detection, analysis, controls and prediction.

For researchers, the findings provide relevant guide for further investigations into AI and climate risks within the PPP research domain.

This article highlights the AI tools in mitigating climate crisis in PPP infrastructure management.

This article provides strong arguments for the utilisation of AI in understanding and managing numerous challenges related to climate change in PPP infrastructure projects.

As the foundation of social and economic development, infrastructure development projects are characterized by large initial investment, high technical requirements and thus generally delivered through complex contractor–subcontractor collaboration chains. This study aims to characterize the complexity of collaborative networks between contractors and subcontractors for infrastructure development through comparing the structural characteristics and the formation mechanisms of contractor–subcontractor collaborative networks for the following two different types of infrastructure: public works (PWCN) owned and operated by government agencies, and public utilities (PUCN) owned and operated by nongovernment agencies.

Based on the method of stochastic actor-oriented models and the longitudinal dataset of National Quality Award Projects in China during 2001–2020, this study compares how the structural characteristics of project-based collaborative networks between contractors and subcontractors for the two types of projects are different and how related micro-mechanisms, including both structure-based endogenous network effects and attribute-based exogenous homophily effects (institutional, organizational and geographical homophily), collectively underpin the formation of the networks.

The empirical results provide evidence that while the two networks are both characterized by relatively low levels of network density, PWCN is more globally connected around a minority of superconnected contractors as compared with PUCN. The results further reveal that compared with PUCN, the formation of PWCN is more significantly related to the structure-based anti in-isolates effect, suggesting that PWCN is more open for new entrant subcontractors. With regard to the attribute-based homophily effects, the results provide evidence that while both significantly and positively related to the effects of organizational (same company group) and geographical homophily (same location), the formation of PWCN and PUCN is oppositely driven by the institutional homophily effect (same ownership type).

As an exploratory effort of using network perspective to investigate the formation mechanisms of contractor–subcontractor relationships in the infrastructure development domain, this study contributes to a network and self-organizing system view of how contractors select subcontractors in different types of infrastructure projects. The study also provides insights into how contractor–subcontractor collaborative relationships can be better manipulated to promote the development of complex infrastructure in different contexts.

In the past few decades, traditional project management theories mainly focused on quality, cost and schedule. However, with larger scale and wider influence of infrastructure projects, especially in megaprojects, social problems have gradually become pressing issues in the field of project governance. As the public is the main body of society, public participation has attracted the attention from both the academic field and industry field. Despite people are gradually realizing the significance of public participation, a deeper and more systematic understanding is still needed to be developed in this field. Therefore, this paper aims to conduct a systematic literature review on public participation in infrastructure projects. Based on existing literatures, this paper draws a knowledge map and develops a research framework in this field. Also, this paper tries to provide some theoretical and practical directions for the future.

In total, 142 papers from Web of Science Core collection were selected to be used in this systematic review. Quantitative analysis of this paper is concentrated on the knowledge map with bibliometric tools. Qualitative analysis is concentrated on identifying the research framework.

This paper reviewed existing literatures and the results are as below. Firstly, the results show a knowledge map containing knowledge domains, knowledge frontiers and knowledge evolution of research fields in public participation. Secondly, the results indicate a research framework in this field, including situational dimension, implementation dimension, individual dimension and influence dimension. Moreover, each dimension has several research topics, respectively. Finally, according to the results, the paper proposes practical suggestions for stakeholders and research directions for further study.

It is the first paper to draw a holistic knowledge map and build up a multilevel framework for public participation in the field of infrastructure projects. This paper bridges the gap in both quantitative and qualitative identification of existing literatures in this field. Besides, this paper proposes some practical suggestions and research directions for further study and development of public participation.

Developing countries are increasingly looking to private sector investment for infrastructure development. Successful development of private infrastructure projects, however, depends on adequate availability of long-term debt to complement private sector equity. As domestic bond markets in many emerging countries are not very deep, availability of long-term debt funding for infrastructure has been limited. Recently, a new form of financial intermediation has emerged in India with the creation of infrastructure debt funds (IDFs) to create capital pools for long-term debt funding. This paper aims to analyse the effectiveness of IDFs for financing infrastructure projects.

This paper uses a case study approach. The case studies were written using both secondary and primary information. Secondary information was obtained from various sources such as policy papers, websites and other published sources. Primary information was obtained from interviews with the top management of three IDFs. Information obtained from multiple sources was triangulated for consistency and correctness.

IDFs have emerged as an effective intermediation mechanism for attracting long-term capital by offering a new investment product with appropriate risk-adjusted returns. For the fund seekers, IDFs are able to provide long-term capital at lower rates and higher flexibility. Unlike commercial banks, IDFs are able to add value to the projects apart from funding by periodic monitoring of the projects.

Creating new forms of financial intermediation can help in reducing the financing gap for infrastructure projects, especially in emerging countries.

IDFs have been analysed from a perspective of financial intermediation. The effectiveness of IDFs in bridging the funding shortfall has been evaluated from multiple perspectives.

The purpose of this paper is to consider the merits of using projects bonds to finance infrastructure investment projects and considers the pricing of such bonds and the level of risk premium demanded by the market.

The research used a mix of qualitative and quantitative methods with desk-based study and interviews. Interviews were held with policy makers, local authority staff, planners, developers, investors, fund managers and academics. Infrastructure bond data were obtained from the Bloomberg database on all project bonds issued in four Asian countries – Malaysia, China, Taiwan and India – over the period 2003-2014.

The analysis indicates investor appetite for project bonds and suggests that a risk premium of between 150 and 300 basis points over the comparable government bond is appropriate depending on the sector and the degree of government involvement in underwriting the issue.

The paper argues that the introduction of project bonds would be an important innovation, assisting the financing of infrastructure investment at a time when bank lending is likely to remain fragile. The current conditions in the sovereign debt market, where strong demand has forced down yields, has opened up the opportunity to introduce project bonds offering a higher yield to satisfy institutional investment demand for long term fixed income products.

The originality of this paper stems from the analysis of the merits of using projects bonds to finance infrastructure investment projects, the pricing of such bonds and the level of risk premium demanded by the market.

The purpose of this study is to identify and critically assess the barriers to bond financing for public–private partnership (PPP) infrastructure projects in Nigeria using an empirical quantitative analysis. Innovative ways to finance long-term infrastructure projects had been documented. However, there is a dearth of empirical studies on the barriers to bond financing for PPP infrastructure projects.

A comprehensive literature review was conducted to identify the barriers to bond financing for infrastructure projects, which were employed to design a questionnaire. A questionnaire survey was carried out which targeted financial experts in the Nigerian financial institutions/local banks. Data collected were analysed using descriptive and inferential statistics to include mean score, chi-square (χ²) test and factor analysis (principal component analysis).

The analysis of the ranking in terms of the mean score values for the 12 identified barriers indicated that all the identified barriers are considered by respondents as critical barriers to bond financing for PPP infrastructure projects in Nigeria. The study, through factor analysis, grouped the 12 identified barriers into 5 principal factors. These include governance and institutional capacity issues, higher issuance cost and risk, difficulties in getting approval for changes, the small size of bond markets and stringent disclosure requirements.

This research is significant by providing the empirical evidence of the barriers to bond financing for PPP infrastructure in emerging markets, especially in Nigeria.

The findings would enable the policymakers to draw some policy recommendations that will positively influence the development of bond markets in Nigeria and emerging markets at large. These study findings are crucial, as not many empirical studies have been conducted in Nigeria.
