Analysis of Cost Overruns in Public Infrastructure Projects: A Case Study Approach

Thesis Abstract

Title Analysis of Cost Overruns in Public Infrastructure Projects A Case Study Approach Abstract
Cost overruns in public infrastructure projects have been a persistent challenge worldwide, leading to significant financial implications and delays. This thesis aims to investigate the factors contributing to cost overruns in public infrastructure projects through a case study approach. The research focuses on identifying the root causes of cost overruns, analyzing their impacts on project outcomes, and proposing strategies for mitigating cost overruns in the future. The study begins with a comprehensive review of existing literature on cost overruns in infrastructure projects, highlighting key theories, concepts, and empirical evidence. By examining previous research, this thesis sets the stage for a deeper understanding of the complexities surrounding cost overruns and their implications for project management in the public sector. Methodologically, a qualitative case study approach is adopted to explore real-world instances of cost overruns in public infrastructure projects. Through in-depth interviews with project stakeholders, analysis of project documentation, and site visits, the research collects rich data to uncover the underlying causes of cost overruns and their specific manifestations in different project contexts. The findings of the study reveal a range of factors contributing to cost overruns, including inaccurate cost estimation, scope changes, delays in approvals and permits, unforeseen site conditions, and inadequate risk management practices. These factors interact and amplify each other, leading to significant cost escalations and schedule delays in infrastructure projects. Based on the empirical evidence and analysis, this thesis proposes a set of recommendations for addressing cost overruns in public infrastructure projects. These recommendations encompass improvements in project planning and design, enhanced risk assessment and management practices, stakeholder engagement strategies, and the adoption of innovative technologies to improve project delivery efficiency. In conclusion, the study underscores the critical importance of addressing cost overruns in public infrastructure projects to ensure the successful delivery of essential infrastructure assets. By understanding the root causes of cost overruns and implementing targeted interventions, project stakeholders can enhance project outcomes, optimize resource allocation, and contribute to the sustainable development of infrastructure systems. Overall, this thesis contributes to the body of knowledge on cost overruns in public infrastructure projects, offering valuable insights for practitioners, policymakers, and researchers seeking to improve the performance and resilience of infrastructure delivery systems in the face of cost uncertainties and project complexities.
