Prioritizing and selection of contractors are significant in many civil projects. Contractors are the fundamental part of civil projects and they have significant role in turning existing resources into products and services. Therefore, implementation of projects requires an appropriate contractor. Usually contractors are selecting based on the lowest recommended cost. But there are other qualitative and quantitative criteria with different degree of significance that should be considered for selection of contractors. In this paper, in addition to identifying effective criteria for selecting contractors, the significance and priority of criteria is determined by applying a group AHP model for one of the big civil projects of Tehran Municipality.
