【正文】 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。 The current market supply of materials does not meet the standard specifications of the design requirements. These issues have to leave breadwinner project cost factors. Therefore， in the construction process， we must tighten customs change， through no design changes to expand the scale and improve the design standards。 We may have different prices for the items separately. This requires the preparation of the list pilers， seriously study design drawings， Analysis of the tender documents include the elements of the work and the different technical requirements， all familiar with the process， and to the scene of serious investigation， is forecast to make possible the construction of the case， right will have an impact on the Price of projects to be broken down. In addition， because the project inventories to calculate the amount of the project is not plete engineering and consider the interests of the construction units， clearly paying the price for the same overall price， the quantity list by the number of actual construction is a practical terms. In the evaluation and review of the tender offer should do the units total individual Price quotations and the prehensive assessment. Price does not meet the requirements of individual shows Price meets the requirements， and the lowest total Price could not explain the single lowest bidder. Bidders often know the total cost to maintain the same circumstances。 calculate the geometric design of the object， on average。 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 building control very effective， investment projects is not unmon， this will affect owners of investment returns， it adds to the owners and within budget， as well as difficulties in fund owners， the impact on the future management or the owners make payments in arrears， and so on. Hence， the control of the project cost is of great significance， however the project cost is the primary means of control design， Currently most of the property owners in the design stage seldom works on cost control， and they found that the cost of the design will not have a great impact， it is wrong， on the contrary， Design phase of the project cost control is the most important step. Because it determines engineering design， construction methods， materials and equipment types， models of the project cost is of critical significance， design optimization phase of the program or minor changes， project cost will have a significant impact， Design phase of the project cost control of the total project cost of 70%. Following is how to control the project from design to create the Law: As the owners must design， the design selected on the quality level is a direct impact on the quality of product design level， and the design quality products in the level of direct influenc
