This essay displays one of probabilities at Geographical Information System (GIS) as a decision support system to select the best way to carry project's remainders (excavations and garbage of works), in addition to observing topographic characteristics of the study area and the nature of roads which are existed formerly and imposed bonds at the movement of machines as free as possible, As a result, we will obtain the saving economical way to carry, which is a tied goal equation with groups of related bonds about the actual of different ways, and that is accomplished by Geographical Information System. Therefore, it is possible to consider this system as a help tool to improve the effective of approval decision to shorting time at engineering projects.
