      abstract = {The construction industry in Nigeria continues to experience persistent challenges associated with cost overruns, inaccurate cost forecasting, inadequate cost control, scope changes, design deficiencies, inflation, procurement inefficiencies, material price fluctuations, and ineffective coordination among project stakeholders. These challenges are particularly significant in privately developed construction projects, where developers are increasingly required to achieve predetermined project objectives within constrained financial resources while maintaining the required level of quality, functionality, sustainability, and performance. Despite the availability of conventional cost management practices, effective mechanisms for integrating value-based decision-making into the cost delivery process remain inadequate. Value Engineering (VE), which focuses on achieving the required functions of a project at the optimum overall cost without compromising essential performance, provides a potential approach for addressing these challenges. This study therefore aims to assess the cost delivery methods adopted by privately developed construction projects in Abuja, Nigeria. Using information obtained from relevant literature reviews which are acquired from textbooks, journals, conferences and online publication. The findings revealed that Lump Sum (Fixed Price) was the very frequently used cost delivery method adopted by private developed construction projects. It was also found that life cycle cost analysis is a very important value engineering techniques for delivery of privately developed construction projects. The study concludes that stated that the Lump Sum (Fixed Price) method remains the most widely adopted cost delivery method because it provides clients with certainty regarding the total project cost before construction commences. The research recommends that cost delivery should be implemented as a continuous management process throughout the entire project lifecycle rather than being introduced only during the design stage so as to serves as a decision-support tool for construction professionals, private developers, consultants, contractors, and policymakers seeking to institutionalize Value Engineering practices and improve the cost delivery performance of privately developed construction projects.},
