1On the construction project cost management on several important stagesWrite papers Net: Abstract construction project management cost management is an important part of it runs through the start of the tender to the various stages of completion of the project, especially in the cost of the construction phase, the actual cost of construction projects should control predetermined cost of the project within the project cost management is the key to achieve. Key Words the construction project, construction project management, cost management focus, mainly in contract management, quality management, schedule management, cost management, security management and information management, six, and that all six areas of management and cost management are closely related, so the construction project management, cost management is an important part of it runs through the whole process of construction project management, like a pair of invisible hands constraints, impact, promote or delay the construction 2project management. construction project cost management, including cost projections, cost planning, cost control, cost accounting, cost analysis and cost assessment, etc., this series of interrelated and interact in all aspects throughout the project from tender stage to completion and acceptance of the whole process. A tender stage in the tender stage, according to overview of the project description and site investigation, according to the cost of similar construction project information and the implementation of other projects in the near future, market conditions and other factors which may speculate about the future The cost of this construction project the level of impact, on this basis to determine the projected costs of the project, and then combined with the actual management of the enterprise and construction standards, combined with the competitors in the proposed bidding decision-making advice. When making bidding decisions, they immediately admitted to the tendering stage. In the 3meantime, pay attention to do two tasks: First, according to the tender document requirements, drawings and bills of quantities, according to the current implementation of the fixed and the corresponding The fee structure, fee standards, combined with the proposed method of construction design, construction program, technical measures and the situation on the preparation of a detailed and reasonable project budget. A good project budget, not only increased the chances of winning, but also in project cost management an important basis for cost control and secondly, to seriously study whether the open project, and how to deal with these open item in the offer be reflected in the reasonable. 2 construction contract bid preparation stage, the project developed by the Ministry according to the company the cost of managing the content and ideas, to sub-project based on the amount of physical work, contact work quotas, material consumption norms and technical measures of conservation plans, in optimization of the construction program under the guidance of the 4cost of preparation of the plan, and prepare detailed and specific cost of the implementation plan, and by sector, the construction team and the team break down the different division of labor, the cost of implementing the responsibility to go well for future cost control preparation. 3.1 Phase 3 construction work conscientiously do a good job drawing Mixed in drawing Mixed, from the convenience of construction, which will help speed up the progress of the project, to ensure project quality, while reducing resource consumption, increase revenue several engineering aspects, put forward amendments, some obvious loss of the item, without affecting the quality of the premise, put forward a reasonable alternative measures for building recognition units and design units. 3.2 optimize the construction design. Construction schemes, the duration will be different, put differently, so the optimization of the construction program is cost-effective control of the project the main 5way. Prepare a technically advanced and reasonable process, the organization capable of the construction program, the sub-balance arrangements the progress of the project. choose the most suitable project construction machinery, to the maximum extent possible to meet the construction requirements at the same time, focusing on economic considerations. considering the rental fee, the basis of advance and retreat fees and equipment costs of field, while strictly control the advance and retreat field time, a reasonable schedule working materials, to eliminate the backlog, idle, wasted, on-site carefully arranged to avoid the handling of secondary materials, temporary facilities, to consider the production of peak demand, in one step. 3.3 well-organized, good job process management. Organize a force is the core competitiveness of enterprises, reducing management
