【文章內(nèi)容簡介】 t, short duration of construction enterprises, and this is the ultimate goal tender. I have participated in internships over the course of the project bidding, and pleted over part of the calculation of quantities, bined with graduate experience in the design process, a brief analysis of the mode Quantities Call for Tender The meaning of risk and risk characteristics of the general construction, the lowest price sealed bidding construction method produces several risks and incentives, according to their characteristics discussed the feasibility of risk control and prevention. Comparison of engineering and engineering security risk management, insurance, similarities and differences between the two projects and benefits。 construction project bidding and tendering process characteristics of human behavior is analyzed to reveal the bidder39。s risk appetite and behavioral characteristics with changes in the external environment change, when the default punishment is light, the bidder preference appetite for risk and default penalties, with the increase exceeds a certain value, the risk of bidders to show preference for behavior change to avoid the risk of penalties, the greater the bidder biased in favor of a more riskaverse behavior, the results of the control and prevention of risk behavior of bidders has an important and practical significance Construction Cost Management from the quantityone price plan model to price of separation volume model of the market, and gradually establish a market pricebased price formation mechanism, the price of the decision in the hands of the parties involved in the market, and ultimately the allocation of resources through the market in order to realize through the market mechanism to decide on project cost. This will standardize the construction marketpetitive behavior and the promotion of project bidding mechanisms play an important role in innovation. It can be said that the implementation of the project bill of quantities is a project cost management system in our country a big step forward, but also in China39。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. Therefore, the lowest reasonable price of the successful bidder My future is the most important evaluation methods. At this stage due to the implementation of projects bill pricing model and the problems mainly against China at this stage in the minimum reasonable price of the principles of the successful bidder, most contractors have not yet set up their own enterprises of scale, panies unable to determine the reasonable Cost. This article is a scientific and fast set reasonable cost to study the key. First, from the project cost of the basic concept, of the engineering bill pricing model under the cost structure, to accurately predict costs of the project provided the basis, considering the average cost of the social cost to individual enterprises and the tender stage of the cost es
