Aiming at a higher gasoline production level and in order to enhance gasoline selfsufficiency in the country, and export the environmental friendly by-products with higher addedvalue instead of raw crude oil, NIOEC1 decided to de-bottleneck and revamp the existing refineries and construct several new oil refineries; in platform of several mega oil refinery projects. Most of the mega oil refineries programs are managing in the form of multi-projects environment with different Contractors which create several challenges which are fundamentally different from a single project.Recent mega oil-refineries projects in Iran have all experienced significant delay during execution phase which negatively impact the relation between time, cost, scope, quality, and resources. There are many reasons for these overruns, but based on some investigations and lessonslearned; one of the most important factors is poor interface management and coordination between different project parties during execution phase.The objective of this paper is to create a comprehensive road map dealing with interface management subjects at the beginning of the project life cycle (i.e.: Front-End Loading), in order to properly identify and mitigate the potential causes, and prevent any scope creep in the next project phases.
