In building engineering bidding law enforcement and the practice of project construction supervision system on standardizing China39。s Republic of China for bidders, bidding regulation, enterprise strictly, put forward to bidders professional requirements of project profile was illustrated. Nowadays in the engineering construction industry, the market which is characteristic for project bidding, has formed. The construction panies,which want to create good benefits, have to control their cost and improve management to enhance the capacity of adapting and peting in this market. This article focuses on how to decrease cost and increase ine so as to control the construction cost effectively. In building engineering bidding law enforcement and the practice of project construction supervision system on standardizing China39。s Republic of China for bidders, bidding regulation, enterprise strictly, put forward to bidders professional requirements of project profile was illustrated. The practice of project bidding purpose is to market petition of openness, fairness and justice. However, due to the construction market development is not standard, management system and the experience of inadequate, architectural engineering bidding in concrete operation exist in ACTS of unfair petition, and some drawbacks. This obviously violate the bidding, the bidding process, and will lose its significance for other bidder fails to bid is unjust, disturbed the bidding project contracting market economic order, for activities, this kind of behavior must be prohibited, only in this way can we make construction engineering petitive trading activity lawfully healthy. This subject will I learned and social practice, present situation and construction project bidding system is expounded, and the disadvantages of bidding for construction project with ACTS of unfair petition phenomenon and analysis of causes, and finally make corresponding preventive countermeasures. Construction cost management system, both theoretical discussion, but also need to practice innovation. Under the conditions of market economy, project cost management, petitive and orderly market for construction management services platform structures. In such a premise, the original scale and method of valuation is inappropriate, and this needs to be reformed and improved. The spirit of the government39。 construction project bidding and tendering process characteristics of human behavior is analyzed to reveal the bidder39。s accession to the WTO, the global construction industry a powerful tool for peer petition With the construction of indepth development of the market, the traditional fixed pricing model no longer suited to marketoriented economic development needs. In order to adapt to the current project bidding by the market needs of a project cost, we must work on the existing valuation methods and pricing model for reform, the implementation of projects bill pricing. Engineering is a list of pricing model and adapt to the market economy, allowing independent contractor pricing through market petition determine prices, with the international practice of pricing model. With the bill pricing model projects to promote, in accordance with international bidding practices is imperative. Therefo
