【正文】 y of materials do 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。 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. ⅵ 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 choose both economic and scientific potential solutions, overe the waste caused by mand, to give due attention to the importance of investment in conservation, is responsible for the engineering technician with the bination of economic officers from the tender, contract negotiations, costing the budget, signed paid to the progress of the pletion of the accounts, a cost analysis, the whole process management and strictly control the cost of the project. Do a good job clearing price pletion of the assessment project is the pletion of settlement construction enterprises in accordance with the provisions of the contract internal pleted by the contractor, experience resumption quality standards and ply with contract requirements, to the building of units of the final settlement price of the project. After the pletion of the audit settlement is approved construction project cost basis. Clearing the pletion phase project cost control. For a long time, the pletion of construction drawingsclearing budget is the cost management problems to be solved. Therefore, the pletion of the audit settlement is a very important task, should focus on acplishing the following aspects: To audit the accuracy of output. The project is the pletion of audit settlement audit, the most important and most plex, one of the most meticulous work, must plan to the pletion of the project, design changes and construction site as the basis, fixed in strict accordance with the provisions of engineering calculation rules itemized audit, to prevent the construction of the project pleted clearing inflated output to increase the cost of the project. Review of fixed quote is correct. Review included a breakdown of the price with a fixed price in line, their names, specifications, Measurement units and the contents contained units with the valuation。s entry into the WTO, China was the main investment diversification, investment side of cost reduction, cost control, improves returns on investment increasing attention. Therefore, changes to the original construction cost estimate, budget, budget, contract prices, and the settlement price accounts for the pletion of the move. Lack of continuity of the situation, the launch control system investment projects, investment in construction projects to improve the level of control. Can promote the count
