The construction projects are carried out to develop the infrastructure, building and services as part of the development of any country. The construction projects which were carried out in UAE before faced several problems and most notably cost and time overruns. This sometimes leads to the disputes and dissatisfaction among stockholders. Hence, there is a need for a study to investigate the same and try to apply the concept of ‘best value’ in order to improve the success of public construction projects. This will be achieved by the concept of ‘best value’ in order to facilitate a clear appreciation and understanding of the concept, articulate the scope of the concept of ‘best value’ as conceptualized within construction project management and articulate, identify and categorize the concept of ‘best value’ within the United Arab Emirates complex public sector. Therefore, this research propose research methodology for developing an assessment model for outcomes based best value using Multi Criteria Decision Making tool to prioritize the most important criteria. Further studies will follow this research to entirely develop a model according to proposed research methodology.
