Contractor evaluation is a vital part of the project management cycle and deals with risk and risk management. One of the most important phases in the construction industry is the bidding process. in order to select the most appropriate contractor for the project and prepare the most realistic and accurate bid proposal, stakeholders have to know all financial, technical and general information about these contractors. The information can be determined as qualitative, quantitative or verbal data. This paper presents the multi-attribute contractors ranking method bay applying Ordering of feasible alternatives of solutions in terms of preferability technique. This method allows dealing with qualitative and quantitative data as well as with data expressed in words (verbal data).
