This research explains the systemic flaws in project management that have been causing cost and time overruns in large construction projects in India. Urbanization, lack of resources, and infrastructure construction have been behind a string of spectacular failures, which have been pointing towards failures in planning, quality, risk management, and stakeholder management. The paper leverages a framework of existing literature based on worldwide project management models such as PMBOK and PRINCE2, supplemented by local examples such as Delhi NCR Highway Expansion, Kochi Flyover, and Mumbai Metro Rail Extension to illustrate the systemic nature and complexity of the case and performance of these projects. The research contains a mixed methodological approach, employing variable statistics including regression and Relative Importance Index (RII) analysis, and qualitative interviews and case studies to provide data and evidence that show how managerial flaws can cause serious budget and schedule overruns. The findings demonstrate a significant prevalence of inadequate risk management, ineffective planning, and decentralized accountability that leads to 15-25% delays and cost overruns of 30-65%. To mitigate future risks, improve project performance, and therefore contribute to sustainable industrial development, the recommendations emphasize the use of digitized technologies, the establishment of improved scheduling, communication with stakeholders, and effective compliance with regulations.
