Environment is the atmosphere where mankind lives and interact with its component, whereas the growth of human's requirements has made great changes of the environmental system .So the environmental evaluation become one of the most important tool to reduce the impact of enhancement projects .Concrete works impact seems to be complicated and massive but some of them has lately effects which never appear soon. Nevertheless, the environmental evaluation considered very necessary and has such a big importance as a tool to make a decision, so that the concrete equipments are the serious element in environmental evaluation of concrete projects. Environmental evaluation to Huge concrete works will directly focus on the concrete equipments which have the clear effects on environment so the Environmental evaluation purpose is to reduce or prevent the negative effects which is expected in such as works, also it can be used as a tool in management and planning projects through inserting the environmental consideration in projects planning. In order to discuss this problem we used the fuzzy logic theory.
