This study aims to identify the crucial barriers to interface management and understand the interdependencies in Large Infrastructure Construction Projects (LICP). Threepronged sequential explanatory mixed methods research is adopted comprising a structured survey of experts (n=102) and semi-structured interviews (n=13). Subsequently, interpretive structural modelling (ISM) integrated with fuzzy protocol is used to analyse pairwise interrelationships among these factors. A 'Multi-layered IM barrier' model is developed with 'Process related issues,' 'Misaligned incentives among project stakeholders' and 'Frequent Change Orders' as the manifested barriers. On the other hand, this study also prioritized the barriers and classified them as driving, linking, and independent. The outcome of this study presents the interdependence of barriers and classification of barriers, focusing on proactive action on driving barriers, which is crucial to the knowledge of interface management. The impact position of LICP with the identified project issues can be compared against 'Multi-layered IM barriers' and can help project teams better strategize IM by focusing on essential barriers. In addition, such exercises can improve the coordination among participants in construction projects. Using a structured approach to identifying interdependencies among barriers to IM is a significant original contribution by the study.

The European Union has set ambitious targets for deployment of renewable energy sources to reach goals of climate change mitigation and energy security policies. However, the current state of electricity transmission infrastructure is a major bottleneck for further scaling up of renewable energy in the EU. Several thousands of kilometers of new lines have to be constructed and upgraded to accommodate growing volumes of intermittent renewable electricity. In many countries, construction of electricity transmission projects has been delayed for several years due to concerns of local stakeholders. The innovative BESTGRID approach, reported here, brings together transmission system operators (TSOs) and non-governmental organizations (NGOs) to discuss and understand the nature of stakeholder concerns. This paper has three objectives: (1) to understand stakeholder concerns about the deployment of electricity transmission grids in four pilot projects according to five guiding principles: need, transparency, engagement, environment, and impacts on human health as well as benefits; (2) to understand how these principles can be addressed to provide a basis for better decision-making outcomes; and (3) to evaluate the BESTGRID process based on feedback received from stakeholders and the level of participation achieved according to the ladder of Arnstein. This paper goes beyond a discussion of “measures to mitigate opposition” to understand how dialogue between TSOs and the public—represented mainly by NGOs and policy-makers—might lead to a better decision-making process and more sustainable electricity transmission infrastructure deployment.

This study assesses the potential for job creation through infrastructure investment in the Middle East and North Africa. The region has experience in making the most of infrastructure investments, but maintaining and spreading the momentum in infrastructure will be important to support future growth and job creation. To do so, policymakers will have to recognize that there are large differences in initial conditions across the region in terms of starting stock, needs, fiscal commitments, private sector participation and job creation potential. Overall, the region’s infrastructure needs through 2020 are quite large and estimated at about 106 billion dollars per year or 6.9 percent of the annual regional GDP. The differences in infrastructure and maintenance needs across sub-regions are also impressive, with developing oil exporters expected to require almost 11 percent of their GDP annually, while the oil importing countries and the GCC oil exporters expected to need approximately 6 and 5 percent of their GDP, respectively. Investment and rehabilitation needs are likely to be especially high in the electricity and transport sectors, particularly roads. Rehabilitation needs are expected to account for slightly more than half of total infrastructure needs. While oil exporters will be able to meet their national infrastructure needs if they maintain investment spending at rates prevailing in the 2000s, oil importers will fall short. The infrastructure sector has the potential to contribute to employment creation in MENA. The region could generate 2.0 million direct jobs and 2.5 million direct, indirect and induced infrastructure-related jobs just by meeting estimated, annual investment needs. However, the potential varies greatly across countries, and infrastructure alone will not resolve MENA’s unemployment problem. Going forward, decisions on what types of public spending to expand and what to downsize in order to achieve balanced budgets will have important implications for jobs. In designing country specific solutions, governments will have to tackle predictable challenges: the governance of job creation, the proper targeting and fiscal costs assessment of subsidies needed to create jobs, the design and fiscal costs of the (re)training programs needed and the expectations on the job creation effects of infrastructure.

The practice of implementing infrastructure projects through a public-private partnership (PPP) arrangement is widely employed around the world with successful outcomes. However, this practice is not without challenges related to cost, time and quality variations, which the public is forced to bear. This study aims to explore factors influencing the termination of the East West Link project in Melbourne and present time and cost variation challenges facing the Sydney Light Rail project. This paper utilizes literature, investigating the critical success factors (CSF) for PPP infrastructure projects in an international context, and other readily available data sources such as Australian government publications, the case projects’ reports, news articles, and websites as the sources of data. The data gathered from these sources was then analysed to understand the project challenges and to investigate the relationship between CSF and the challenges. Four challenges were identified, including insufficiency of the business case, political interference, non-independence of implementing organizations and insufficient risk profile identification. The findings can assist to cover the loopholes that might cause similar failures in project planning, risk management, and policy and guideline frameworks. However, efforts should be made in improving the existing policies to accommodate political interests as part of risk measures under the national PPP guidelines. 

This book examines complex challenges in managing major strategic economic and social infrastructure projects. It is divided into four primary themes: value-based approach to infrastructure systems appraisal, enabling planning and execution, financing and contracting strategies for infrastructure systems and digitising major infrastructure delivery. Within these four themes, the chapters of the book cover: the value and benefits of infrastructure projects planning for resilient major infrastructure projects sustainable major infrastructure development and management, including during mega events improving infrastructure project financing stakeholder engagement and multi-partner collaborations delivering major infrastructure projects effectively and efficiently whole-life-cycle performance, operations and maintenance relationship risks on major infrastructure projects public-private partnerships, design thinking principles, and innovation and technology. By drawing on insights from their research, the editors and contributors bring a fresh perspective to the transformation of major strategic infrastructure projects. This text is designed to help policymakers and investors select and prioritise their infrastructure needs beyond the constraining logic of political cycles. It offers a practical set of recommendations for governments on attracting private capital for infrastructure projects while creating clear social and economic value for their citizens. Through theoretical underpinning, empirical data and in-depth informative global case studies, the book presents an essential resource for students, researchers, practitioners and policymakers interested in all aspects of strategic infrastructure planning, project management, construction management, engineering and business management.

PurposeManaging mega infrastructure projects (MIPs) is more complex because of time, size, social, environmental and financial implications. This study aims to address the management approaches, complexity and risk factors involved in MIPs. The study focuses on project success criteria and their individual effects on the success of MIPs.Design/methodology/approachTo address the challenges and identify the most influencing factor for the success of MIPs, the study deployed a cross-sectional survey approach. Six hundred eighty-two usable samples were collected from the respondents to understand the impact of predetermined factors on the success of MIPs. The structural equation model and artificial neural network approach were used to derive the importance of factors affecting the success of MIPs.FindingsThe study's outcome confirms that all three influencing factors: feasibility studies, community engagements and contract selection, have a significant positive impact on the success of MIPs. Community engagement amongst all three has the most influential predictor for the success of MIPs.Originality/valueThe developed model will enable practitioners and policymakers from Indian construction companies and other emerging nations to concentrate on recognized risk reduction variables to enhance project success criteria and project management success, especially for MIPs.

Objective: This study sought to establish the relationship between stakeholder engagement practices and the performance of road infrastructure projects in Central Equatoria State, South Sudan.   Theoretical Framework: The key stakeholder engagement practices explored in this study included stakeholder identification and mapping, communication, feedback mechanisms, involvement in decision-making, and conflict resolution while project performance was evaluated in terms of schedule adherence, cost efficiency, and quality outcomes. This study will be anchored on three theories namely; stakeholder theory, resource dependency theory, and social exchange theory.   Method: The study adopted a descriptive research design where stratified random sampling techniques was used to collect data from 58 respondents drawn from various stakeholder categories, including project managers, engineers, contractors, government officials and community members. Data was collected using structured questionnaires and analyzed using both descriptive and inferential statistics. Inferial statistics involved multiple regression analysis that assessed the relationships between stakeholder engagement practices and project performance.   Results and Discussion: The results indicated that communication and stakeholder identification had the strongest positive influence on project performance, while feedback mechanisms, decision-making involvement, and conflict resolution also contributed but to a lesser degree. Challenges such as resource limitations, diverse stakeholder interests, and inconsistent feedback collection processes were identified as barriers to effective engagement..   Research Implications: The study concluded that structured and inclusive stakeholder engagement strategies are essential for enhancing project outcomes. The study recommended the adoption of digital tools, regular stakeholder training, and culturally adaptive engagement practices.   Originality/Value: The study helps project managers to appreciate various dynamics of stakeholder engagement and project performance in resource-constrained and conflict-affected road infrastructure projects. Equally, policy makers benefit when designing and implementing policies that enhance stakeholder engagement for effective project outcomes. Therefore, future studies can refine and expand literature on stakeholder management and project performance.

The persistent decline in infrastructure spending, notably within the transportation sector, raises concerns about governments’ capacity to meet the demands of a sustainable growing economy. The incorporation of risk assessment in the analysis and computation of potential cost overruns emerges as an effective and efficient tool, underpinning the economic and financial sustainability of infrastructure expansions. Focusing on the “State Road No. 51 of Alemagna Vittorio Veneto” (SSv-51) variant, this study analyzes and proposes a model to forecast the possible cost overruns of an infrastructure project. The application of the risk assessment tool proposed by the National Anti-Corruption Authority (ANAC) offers valuable insights into potential risks associated with project costs and their valuation. The matrix developed in the current study draws from the ANAC Matrix, which comprises four categories of risk divided into 21 risk types. The selection is based on the project’s characteristics, and a matrix is compiled that forecasts the combination of the probability of risk occurrence and the cost impacts on the project. The proposed risk matrix serves as a practical tool for managing uncertainties and estimating potential cost overruns, estimating ex ante a possible cost increase of 7.53%. This projected increase differs only by 1.34% from the final execution costs, mitigating the unforeseen cost overruns not estimated by the initial project. The proposed risk assessment tool emphasizes the importance of integrating risk management into project planning and execution. The research investigated an applied case utilizing an easily adaptable tool, suitable for potential future implementation, further advancement, and broader testing across various project samples in the future. The study provides a framework to assess and mitigate risks linked to cost overruns. As nations navigate infrastructure development complexities, proactive risk management practices are indispensable for efficient resource management, ensuring the economic and financial sustainability of these complex projects.
