Since long, our country building cost of projects management has been places the engineering project completion settlement stage, the construction cost manages engineer's primary mission is with emphasis after the engineering project implementation finished acted according to the project blueprint, in the project implementation change situation, the construction organization plan, the government construction cost Control section promulgation building cost of projects computational method determination completion project total construction cost. But implemented along with "Tender Tender" in January 1, 2000, established the move of bid system in our country construction market dominant position, the competition has become the market to form the building cost of projects the main form, particularly the state-owned fund occupies the main body the construction project, for the enhancement investment benefit, guaranteed that the state-owned fund the effective use, must implement the tender.
