Recently growing rate of construction projects caused to expanse of construction industries.Unfortunately recent increasing demand on construction projects caused projects which do not matchappropriately with construction industry's approaches and this caused delays in a part and sometimes whole of the projects. This will take into consideration when we understand that a large amount of national expenditures includes construction projects costs. These delays cause damages intoinfrastructure. Recently using fuzzy methods and multiple attribute decision making have become usual for help of managing and efficiency construction in worldwide .these methods are based on fundamental indicators by putting them in phase category and grading them decision making is done. Thus this paper surveys and explains four common approaches in construction projects and finally by using fundamental indicators in project delays these approaches will be graded by Fuzzy TOPSIS methods and Multiple Attribute Decision Making (MADM).
