【正文】 ol is the main， the cost of materials in engineering often holds substantial proportion， usually accounts for the estimated costs of 70%， representing the direct costs of 80%. It is necessary in the construction phase in strict accordance with the contract amount of material control。 From parison choose the best design. Construction phase of the project implementation unit construction cost management to control the cost of the project is reasonable in the project to meet quality standards premise， in the investment decisionmaking stage， the design phase and construction phase of the project put the project approval occurred in the control limits， strive in various construction projects rational use of human， material and financial resources to achieve good investment returns and social benefits. The project cost control and management is a dynamic process. The dynamic market economy， to make the investment in the identification and control bee more plex， this will require the construction units to the management of project cost to the project runs through the entire process， it is necessary to have a prehensive focus. The implementation phase of the projects. The implementation phase of the project cost management is the the stage of the project cost management 10 implementation of the entire process of project management. Project implementation phase of the project cost management can be divided into three parts: the tender management ， construction management and settlement management. Bidding for the construction phase of the construction units Bidding system control engineering cost effective means， bid organization can improve the costeffectiveness of construction projects and ensure the quality of construction projects， shortening the construction cycle return on the investment， construction units can take full advantage of bidding for the effective means of cost control. Construction No. 10 on the 7th ministerial decree issued a contract with the Construction Contract Pricing Management. clearly pointed out in bidding for projects using inventories. This requires the building of units conducting the tender exercise， in the tender document to include not only the usual content， like tender notes before schedule， tender notes， the conditions of the contract， the contract terms of the agreement， contract format， technical specifications， drawings， tender documents and other reference format， it is also necessary to provide the engineering inventory， Bidding as a reference document of the important ponents. Construction units in the tender document for the project inventory， in accordance with state or local rules promulgated by the calculation that the reunification of the divided projects， unified measurement units and the reunification of the engineering calculation rules， according to design drawings to be calculated and statistical arranged， obtain the list. Quantities to be followed in the preparation of an objective， impartial， scientific， and rational principle. Compilers must have strong manly budget， and should have certain knowledge of the engineering design and construction experience， and the material and mechanical construction technology for the stage of the project cost management 11 prehensive scientific knowledge， in order to calculate the volume of the works without heavy missed. The basis of which must be in accordance with state regulations engineering calculation rules， and the subprojects division engineering units， and in accordance with design drawings， design essential Love tender documentation requirements are calculated. Quantities of the project should have a testing general， the entries must be simple， while not appear Lousing wrong items Pricing should guarantee the correctness of the project. Should the requirements of the different grades separate engineering division， the situation was different。s technical and economic decisionmaking， of the construction project cost of the project after the pletion of the economic benefits have a decisive influence， The construction cost is an important stage control. China39。the stage of the project cost management 1 the stage of the project cost management Abstract： Project cost management is the basic contents to determine reasonable and effective control of the project cost. Described the current stage of the project cost management situation on the strengthening of the various stages of construction cost management of the importance of and raised a number of key initiatives. Keywords： project cost； the current stage of the project； project cost management； Even under the WTO and China39。s current stage of the project cost for the project management for the purpose of clearing price， and focusing only on the construction process of cost control， neglected before the start of the project investment decisionmaking stage of cost control. Investment decisionmaking phase of investment projects is estimated an important basis for decisionmaking. It the stage of the project cost management 4 has a direct impact on national economic and financial analysis of the results of the reliability and accuracy. Because of this phase is the preliminary work of projects， the information cannot be fully， parable works more or less that information accumulated relatively small， estimated inadequate and unscientific. Makes project cost management and cost workers is difficult at this stage do something. The various stages of the project cost control in the decisionmaking phase project cost control. Right project planning phase of the cost， many owners have the wrong understanding that the lower the cost the better. Cost control is not a unilateral issue， and should be a number of factors，
