Post Evaluation of Soufi - Chai Multi Function Project

The socio-economic assessment of economic projects is performed in the three phases of; Pre before constructional operations, during the going on of the operation and finally after completion. Evaluating the project after performing the construction process or during the construction period may reveal some unforeseen benefits or costs unknown beforehand, this either weakening or strengthening the economic justification of the project. Given the above facts, the purpose of this study is to revaluate the multi-functional project of Sufi-Chai that constitutes Alavian dam, irrigation and drainage network, water refinery of Maraghe and water transfer from the refinery to the city. Considering the fact that many years have passed from the termination of this project, in this study it is tried to examine whether the originally foreseen cost and benefits have been realized as well as to consider the newly arisen revenues and expenses since then.The post evaluation is carried out using "Net Present Value", "Internal Rate of Return", "Benefit/Cost Ratio" and "Capital Recovery Factor" criteria using" Microsoft Excel" and "Cornfar III Expert" softwares. The findings of the study do notjustify the economic feasibility of the project. Assuming a 20 percent increase in the revenues and similar decrease in the expenses, doing a sensitivity analysis, did not justify the project either. Theresults show that it is very critical to consider the untangible benefits and costs in addition to tangible ones in dam construction projects. The limitation of budget and data did not allow consideration of non tangible returns and expenses in this study. To the extent that they could beestimated, they did notcontribute to thejustification of the project.
