In implementing construction projects it’s not hidden to anyone the importance of three parameters of time, cost and quality. Private public sector employers are always looking for scientific methods to reduce cost, time and eliminate unnecessary workers. Fortunately with advances in technology and science of construction, particularity knowledge of projects management in recent years various methods have been developed to achieve these goals in the project that are among these various methods value engineering are relatively well- known and functional . This research has been done to improve the principle of reducing the cost and time by maintaining and improving quality specifically for office and commercial and interviewed with managers and value engineering teams. The research has been done by overviewing several projects running in Tehran and the result of those projects shows; reducing implementation cost up to 5% of the initial value, and reducing execution time up to 25% of the initial time calculated. It’s also anticipated that, with the distribution of creativity, the cost reduction will increase up to 10% .
