The increasing urgency to address climate change in construction has made green construction (GC) and sustainability critical topics for academia and industry professionals. However, the volume of literature in this field has made it impractical to rely solely on traditional systematic evidence mapping methodologies.

This study employs machine learning (ML) techniques to analyze the extensive evidence-base on GC. Using both supervised and unsupervised ML, 5,462 relevant papers were filtered from 10,739 studies published from 2010 to 2022, retrieved from the Scopus and Web of Science databases.

Key themes in GC encompass green building materials, construction techniques, assessment methodologies and management practices. GC assessment and techniques were prominent, while management requires more research. The results from prevalence of topics and heatmaps revealed important patterns and interconnections, emphasizing the prominent role of materials as major contributors to the construction sector. Consistency of the results with VOSviewer analysis further validated the findings, demonstrating the robustness of the review approach.

Unlike other reviews focusing only on specific aspects of GC, use of ML techniques to review a large pool of literature provided a holistic understanding of the research landscape. It sets a precedent by demonstrating the effectiveness of ML techniques in addressing the challenge of analyzing a large body of literature. By showcasing the connections between various facets of GC and identifying research gaps, this research aids in guiding future initiatives in the field.

Public private partnerships (PPPs) face challenges in implementation and operation, and need efforts to improve their performance. The purpose of this paper is to review the PPP literature quantitatively and qualitatively, in order to establish challenge themes and set research directions.

More than 4,000 papers published between 2008 and 2017 were retrieved. From this collection, papers from five major international journals were selected to explore extant PPP research findings under six main PPP challenges including: challenges related to financial management, concession period and price determination, operational phase, risk management, PPP project procurement and stakeholder management (SM). Initially, the papers were categorised quantitatively into the identified challenges and subsequently the articles were qualitatively analysed and discussed.

Poor SM, the complexity of risk management models, project delivery time and cost overruns, inadequate consideration of whole life-cycle aspects and over-reliance on a Public Sector Comparator for evaluating PPPs are found to be the most commonly encountered issues. These all warrant more extensive attention and innovative solutions.

PPP projects have faced many challenges in practice and also existing research findings have limited application in practice. Challenges highlighted in this research can be a focus area in practice to improve the performance of PPPs.

No previous reviews have explored the challenges relating to PPP projects and how they can then addressed by further studies in the field. This review is intended to address that gap, and should help to shed light on further research directions to address the emerging challenges in PPP procurement.

The present study aims to identify significant barriers to adopting prefabricated construction (PFC) in developing economies using a study in Sri Lanka and develop an integrated strategy framework to mitigate and overcome the obstacles.

The research process included a comprehensive literature review, a pilot study, a questionnaire survey for data collection, statistical analysis and a qualitative content analysis.

Ranking method revealed that all 23 barriers were significant. Top significant barriers include challenges in prefabricated component transportation, high capital investment costs and lack of awareness of the benefits of PFC among owners/developers. Factor analysis clustered six barrier categories (BCs) that fit the barrier factors, explaining 71.22% of the cumulative variance. Fuzzy synthetic evaluation revealed that all BCs significantly influence PFC adoption in Sri Lanka. Finally, the proposed mitigation strategies were mapped with barriers to complete the integrated framework.

The study outcomes are relevant to construction industry stakeholders of Sri Lanka, who are keen to enhance construction efficiencies. The implications can also benefit construction industry stakeholders and policymakers to formulate policies and regulations and identify mitigation solutions.

The study provides deeper insights into the challenges to adopting prefabrication in South Asian countries such as Sri Lanka. Furthermore, the integrated framework is a novel contribution that can be used to derive actions to mitigate barriers in developing economies.

The complicated nature of megaprojects requires appropriate analysis of multiple stakeholders to achieve project objectives and to accommodate stakeholder interests. During the last two decades, many stakeholder theories and empirical studies have sprouted. Although previous studies have contributed to the development of stakeholder theory, it seems that these theoretical advances have not been fully adopted and acknowledged in practices, especially in megaprojects. The purpose of this paper is to explore the evolution of stakeholder analysis and engagement practices adopted in the Australian megaprojects over the last two decades.

Four mega construction projects are described and analysed in this study. Secondary data were first assembled in order to get general knowledge of each case. Interviews were conducted with the project directors. Project documents were collected from the project teams and reviewed. Wherever the project information was unclear, e-mails were sent to the directors and the team members to confirm the details.

Project teams have started to apply snowball rolling and stakeholder attribute assessment methods to analyse stakeholders. However, there is still a way to adopt the “network” analysis perspective because the project teams are reluctant to use complicated tools which need specialists’ assistance. The stakeholder engagement practices have evolved to an extent where the project teams monitor the dynamics of stakeholders’ requirements. Projects teams have identified the importance of continuity to manage stakeholders in these massive projects. However, a structured method selection mechanism for stakeholder engagement has not been developed.

This study will help academics to understand the adoption progress and status of stakeholder management methods.

Factors affecting bid/no-bid decisions of international projects are more complex than those of domestic projects. The purpose of this paper is to identify and rank decision factors considered by variously sized Chinese international contractors (CICs) and categorize those groups of factors important to experienced practitioners.

The analysis of factors identified by a literature review is conducted based on data derived from questionnaire results received from 119 CIC project and bidding managers. The relative importance of factors is measured by mean value and standard deviation. The discrepancy in rank and importance value perceived by variously sized CICs are explored by ranking disparity analysis, non-parametric test and Spearman’s rank correlation coefficient test. Finally, factor analysis is used to categorize the underlying groups of factors considered by CICs.

In sum, 41 factors are identified through the literature review as having an impact on the bid decision. Significant disparities in ranking and importance are found in several factors, which partially affect the consistency of the ranking of factors perceived between large and small-medium CICs. Ultimately, nine major factors are identified as impacting the bidding decision, with “contractor’s capability” and “country risk of the host country,” being the most important.

The weight of a factor considered in a decision varies across contractors as a function of contractor size. Whether using models or subjective judgment in making decisions, it is beneficial to fully understand the main groups of factors influencing the decision. Vulnerability to country risk emerges as the first criterion accessed in the bid decision.

A comprehensive set of factors is established for CICs, including both general factors common to domestic projects, and international factors unique to international projects. All factors are grouped by inferential analysis from the perspective of contractors, which reveals the underlying mechanism of the bid decision-making process. While the data were collected from CICs, the methodology in exploring factors, along with implications, is determined to be applicable internationally.

Australia has a huge stock of community buildings built up over decades. Their replacements consume a large sum of money from country’s economy which has called for a strategy for their sustainable management. For this, a comprehensive decision-making structure is an utmost requirement. The purpose of this paper is to capture their sustainable management from four aspects, i.e. environmental, economic, social and functional.

The design process follows an extensive review of environmental and life cycle assessments and company context documents. Extracted factors are tailored to community buildings management following expert consultation. However, the resulted list of factors is extremely large, and “factor analysis” technique is used to group the factors. For this, an industry-wide questionnaire across Australian local councils is employed to solicit opinions of the list of factors.

The analysis has pinpointed 18 key parameters (criteria) to represent all four aspects. This paper presents the preliminary findings of the factors and the analysis results based on the questionnaire responses.

The final decision-making structure incorporates all these aspects and criteria. This can be used to develop a decision-making model which produces a sustainability index for building components. Asset managers can mainly use the sustainability index to prioritise their maintenance activities and eventually, to find out cost-optimisation options for them.

Most notably, this is the first study to apply all four sustainability aspects (environmental, economic, social and functional) to develop a decision-making structure for Australian community buildings’ sustainable management.

We investigate whether council audit committees relate to municipal fiscal policies. We find that municipalities with audit committees are associated with greater levels of own-source revenue, in that they finance municipal operations with locally raised revenues driven by charges and fees compared to municipalities without audit committees. Furthermore, municipalities with audit committees are associated with less new debt than those without audit committees, indicating more conservative use of external financing. Overall, our results are consistent with municipal audit committees, in addition to monitoring the financial reporting function, playing an advisory role in fiscal decisions, especially when the cost of local government to citizens is high.

The purpose of this paper is to provide a picture of (local) e‐government impact and development philosophy in China, New Zealand, Oman, and the UK.

A survey instrument was used to collect data from policymakers in 114 civil service organisations in four countries during 2007.

Policymakers in every country report only low‐medium levels of agreement that their e‐government initiatives had yielded significant benefits for organisations and citizens alike over a broad range of performance measures concerning service quality, citizen satisfaction, productivity, and management effectiveness. In interactions with stakeholders that are both directive and maintain control over citizens, policymakers also favour the provision of online services that offer ever increasing amounts of information, rather than collaborative service channels that engage citizens in local decision making.

Less than a 100‐percent response rate gives an incomplete snapshot of the e‐government scene in the four countries studied. Also, a lack of understanding of some key e‐government issues plus cultural response bias may have led to erroneous/biased responses.

In an era in which public sector organisations worldwide are under pressure to demonstrate success in service delivery and organisational performance, policymakers do not perceive online services as an opportunity to reduce the costs of physical infrastructure or to improve democracy via shared decision‐making. Thus, further erosions of trust and participation in democracy may continue unless citizens are given similar choices in the democratic system to those they have in their everyday lives.

The paper is undertaken at the local level of government and in a diverse range of countries where the political, social, economic, and cultural environments can differ markedly. It evaluates the significance of key e‐government issues in Western, Arabic, and Eastern contexts, enabling international comparisons to be made across these cultural settings. Impacts of the e‐government initiatives on organisations and citizens are presented and compared; and policymaker attitudes to new technology having the potential to enhance the democratic process are presented.
