Defining project success is an elusive topic. The lack of an agreed definition for project success has long been
the reason for failing to define and evaluate success. In fact, the matter of whether or not it is necessary to define
success remains a huge doubt. The topic may become more complicated in the context of construction industry.
The reasons are high inherent risk, one-of-a-kind end product and vulnerable to various uncertainties. As the
construction project success expands rapidly, the need for identification of new research area increases
simultaneously. This paper, therefore, provides a review of the project success notions and proposes a conceptual
framework that identifies the relationship between success factors and criteria as a new research area in
construction project success. This paper will help researcher to identify the most devoted notions of construction
success and attract more researches to enhance the construction project success.
