These delays have many consequences, including extra costs and losses for interested parties. This might lead to dispute among those who are involved in the project. This article intends to identify the causes of delay in carrying out the mega project of south pars and its consequences. The reason behind the selection of this subject is the huge costs and losses which are imposed on our country following delays in carrying out oil, gas, and petrochemical projects. The main point is to predict and remove obstacles which lead to delay in projects’ execution. This article emphasizes the importance of determining a time frame for projects’ execution so that an appropriate economical planning can be made. Time is very important factor in executing projects and if it is not carefully assessed, it might cause some losses. The results of this study showed that the contractors have a key role in determining the time that is required for the fulfillment of a project. Thus, this article proposes that determining the criteria for contractor selection is the most important factor that affects the time needed for a project fulfillment and should be the subject of future research.
