【正文】 the start positioning in a more reasonable level. The design phase of the project cost control for a long time， China39。s accession to the world munity， China39。 conduct a feasibility study to determine investment estimation and the final preparation of design task. At this stage， the project39。 calculate the geometric design of the object， on average。 material set reasonable prices， so as to effectively control the cost of the project. Market economy material supply a variety of channels， variety and price range materials， construction unit budget management and field personnel should pay close attention to market rates， with the progress of the scene， the market， hand in the construction of the information and materials for the pletion of the accounts provide a strong basis. Technology and economic integration ， strengthening investment control. Effective control of the investment ， from organizational ， technical， economic， contracts， and other measures. Therefore， the construction units must strengthen management， engineering and technical personnel of the economy concept， the quality of education， Training pragmatic working style， the construction side to help improve construction design， reasonable security， financial， and material resources. Accelerate the pace of work to improve the quality of the projects. Construction should encounter problems in a timely manner with the designer linked to。 with the owners of different design options， the need to calculate their own materials and equipment to conduct a cost analysis and study， to the design staff costs， to assist them in the investment limit within limits designed to save and invest. To seek a onetime small investment and economic good design program made the most rational economic indicators. Design actively promote the socalled cap limit design， even with the approval of the design task and investment estimates， guarantee the functional requirements of the premise. The preliminary design and control budget， according to the preliminary approval of the total budget for the design and construction design control. Limits， and every one professional， each of whom have a design threshold of a target. In the design process， designers should progress to more programs， design optimization， ensuring that the design is technically advanced and reasonable， innovative， stylish， and do not break the limit investment objectives， thus eliminating the the stage of the project cost management 9 engineering design raise the factor of safety and design standards， or only consider the technical feasibility of the program， rather than economic rationality phenomenon， the project cost to ensure effective control. Also known as the value of value engineering analysis， is a modern scientific management technique， is a new technoeconomic analysis， is the product of functional analysis to conserve resources and reduce the cost of the purpose of an effective method. It made up for the traditional cost management simply focus on cost reduction and quality management only emphasizes improving the quality deficiencies， construction is conducive to resolving the longstanding long period， a lot of wastage， poor quality， highcost problems. Value Engineering laws generally divided into three steps: assessment of the design of object technology and economic Score。s many problems have also exposed. Generally speaking， the budget estimate is based on direct participation in the management of national economic activity as a precondition. Enterprise is not the actual economic entities. Due to the characteristics of the planned economy， and， at the time under the conditions of productivity， will inevitably bee a shortage in the economy. In severe shortage of modities under the conditions， as long as a certain level of investment， will be certain outputs. In this environment， the project planning and technical argumentation there can be no economic analysis. State control of the project cost constitute key factors equipment and materials prices， wages and taxes of artificial distribution. In this relatively stable economic environment， the budget estimate for the system approved project cost， help the government to carry out investment plans to play a major role. As the socialist market economic system established， requires us to predict project investment and control. In recent years ， international investment project developed to the requirements of prior precontrol and in the middle of control. China， the traditional practice in an objective light on the stage of the project cost management 3 the cause decisionmaking， implementation heavy， light the economy and technology， First， the consequences of victimization， Due to the technical personnel of the project technical and economic concepts and a weak awareness of cost control， cost management makes the quality difficult to raise. Project Cost control is difficult to achieve longterm goals. Second， the various stages of the project management view of the above circumstances， My first academia in the 1980s made the whole process of cost management and control concept， building departments will study the feasibility of projects and the budgets and final accounts to two extended at the request of the corresponding regulations put our cost management concepts and methods referred to a new height. Our task now is to be modern and cost management in line with China39。 Nothing relevant departments to formulate a budget， content， methods and approval， the budget will provide the fixed cost of equipment and materials and fixed price of the budget preparation， approval， management authority， and so on. With the historical process， after recovery， reform and developm
