A construction project can be described as successful when it is completed on time, within budget and according to specifications. Post-evaluation plays a major role in the construction industry when determining whether the project is a success or a failure. The objectives of this paper are as follows: to provide an overview of an organisation's interest in the post-evaluation system of the construction projects in the Gaza Strip, to identify and rank the most important factors used in the post-evaluation system for construction projects, to identify the obstacles of the post-evaluation system and to determine the factors that lead to a successful post-evaluation system. A structured questionnaire was adopted in this study; 40 questionnaires were distributed to international organisations that implemented construction projects in the Gaza Strip. The ordinal data were analysed by the relative important index method, which was used to rank the factors and the groups of the questionnaire and the nominal data were analysed by the relative frequency or percentage.

Cost, time and quality are found to be the most important group factors for the post-evaluation system of construction projects. The factors that are used in the process of post-evaluation include the following: project efficiency, owner satisfaction, project effectiveness, safety, risks, change orders, resources, communication, procurement and the environment.
