Abstract :
    Construction projects in each country as one of the major infrastructure development, is considered and The greatest capital any country, projects of development of infrastructure in developing countries and a major source of economic growth and development of any society is its success in the implementation of development projects. The main issues of concern for employers in the construction projects, the creation of administrative costs and some The unnecessary that this factor, the fear of unfinished projects or a lack of proper implementation of the association will be related to executive agencies. Value engineering and effective decision-making tool for managers and value of opportunities to reduce costs, improve quality, Improved manufacturing, reduce development time, longevity, and sometimes a combination of the above makes it possible. This paper is a case study to investigate the effectiveness of the implementation of value engineering in a tunnel excavation project underpass intersection Tehran. This study, in terms of purpose - the development of the analytical method and progress reports with data analysis software MSP, the successful implementation of value engineering to reduce the cost and expedite the time to report .
