Abstract: Productivity and profitability have been previously noticeable subjects for classic economists. Nowadays, optimization and productivity are main challenges of industry and development. It is estimated that drinkable water consumption in Tehran city will increase during the next 25 years. In order to decrease probable crisis and to prevent lack of water in the future, many projects have been designed and executed. Karaj-Tehran water supply tunnel is a sample of these projects. In this paper, optimum advance rate will calculate through economical view and productivity. Optimum advance rate is calculated for Hara Co (Contractor) according to fix and variable costs. In the conclusion, it was observed that slope of the cost graph is nearly horizontal and the advance rate is between 1200 to 1500 meters per month. Therefore, decrease in graph and also productivity increases by means of advance rate are not noticeable. According to current advancement of the tunnel, (average 400 meters per month) if the project is finished within 35 to 40 months, total productivity will be 1.07 to 1.09. Hence, the contractor will achieve an interest of 9% at maximum.
