Abstract: Brownfield projects, which involve expansion or modification of existing infrastructure or facilities, frequently suffer from cost overruns and schedule delays due to their inherent complexities and unique risks. Unlike greenfield projects, brownfield developments always face additional challenges, such as working within operational restrictions, adhering to governmental or regulatory requirements, managing unforeseen site conditions, and coordinating multiple stakeholders. These factors always cause financial instability, work delays, contractual disputes, and operational disruptions. This paper provides a detailed examination of the primary causes of cost overruns and schedule delays in brownfield projects. The root causes are categorized into financial, operational, regulatory, and managerial factors. Additionally, structured mitigation strategies are proposed, including cost estimation techniques, contingency planning, digital project tracking, regulatory engagement, and optimized procurement frameworks. By implementing the proposed mitigation strategies, project team, contractors, and stakeholders can enhance cost control, improve schedule adherence, and mitigate financial and operational risks.
Keywords: Brownfield projects, greenfield projects, work delays, contractual disputes, operational risks.
