Introduction
Construction project construction project management Cost Management is an important part of its purpose is reasonable and effective control of project cost, in order to achieve effective control of the project Investments, optimize the allocation of resources to maximize the benefits of Investment and its main is to follow requirements of the law of market economy and socialist market economic development situation, the use of market economic laws and scientific management methods and modern management tools to determine the project cost and for its effective control. With the economic changes in project Cost Management system from the original budget estimate management to the whole process, comprehensive management, from static to static management change management, you should run through all aspects of construction, but the actual project Cost Management is often seen as weaknesses in the management and the impact on the realization of the intended purpose, so the building project Cost Management solutions to optimize the effective control of project Investment, to achieve its expected economic benefits of a very real sense.

A construction Cost Management program optimization
1.1 correct understanding of Investment decisions
Project decision-making that choice, and ultimately determine the Investment program, which is the source of construction, before the decision-making should be different options for timely technical and economic comparison, in the Investment decision-making stage should first establish the project control system to various positions on the division of labor control, and do the preparatory work to ensure that decision-making stage to collect more detailed and accurate information and market research should be fully prepared, and the collected statistical data and information processing and handling, according to market demand reasonable project scope and standards of the final implementation of the project feasibility study report, the final response to the program established by optimizing the number of options based on the actual situation of technical and economic comparisons, and try to simplify the process, save construction funds, and should be global, comprehensive reality, full consideration of departure may be the unexpected conditions on the adverse effects of the project cost to ensure the project requirements in the realization of Investment projects on the basis of leaving some room to really play the role of Investment budget control [1 ].

1.2 Optimization
Engineering design projects from the plan will become a reality the first stage of the design to a large extent determine the construction schedule, quality and cost, in the process of building the project played a decisive role design phase should be added the cost optimization large drawings of the design units and review the quality of supervision and standardization of measures through the design of budget Investment limits have been identified as the man to take charge of expanding the base to avoid the cost of design size, and should develop new technologies, new processes and new equipment use, promote its application in Engineering design, optimization of Engineering design and economic indicators to improve the design of technical content, thus improving the overall efficiency of construction projects.

Perform the design limit. Quota design that, according to the design requirements of the mission statement, to ensure that controlled decision-making investment in the design documents under the premise of investment control, in accordance with the written approval of the design task to estimate the amount of investment in the preliminary design, preliminary design estimates the cost limit in accordance with construction design, construction design in accordance with budget cost for construction design professional design to control all its requirements throughout the design process closely with the various professionals in order to achieve technical and economic unity in the design process should consider economic costs program to facilitate and make more sense to strengthen the designer's cost, cost for cost calculation and timely preparation of staff to provide information that the design, the design process does not change afterwards, see the outcome of the design is completed the status quo, to achieve the purpose of investment in the dynamic control [2].

In the architectural design should be healthy, comfortable, low-power and environmental protection, energy, etc., and preferred building orientation, sunshine analysis and building layout, lighting, ventilation and rational arrangement of construction plane, and should control building density, plot ratio and floor area factor, the preferred energy-efficient windows and doors, and make full use of underground space, the structural design should be based on the selection, stratum, capacity use, foundation pit and water solution, steel connections and its applications, concrete strength and mix, selection of underground and above-ground structures and floor structure, selection and other considerations, the design professional should consider the water supply and drainage plan, sewage treatment and rainwater collection and use of the program, gas, power distribution solutions, intelligent solutions to user facilities, green and landscape solutions and professional selection of equipment and specialized materials used and waste disposal program and other considerations.

1.3 Optimization bidding
In a market economy model project bidding should begin with a full introduction of market competition mechanism, in order to achieve the purpose of survival of the fittest to improve enterprise efficiency, and promote the bidders in terms of quality, price and cycle point of view to improve their competitiveness in the market, to a certain extent bidders to reduce costs and achieve the tender stage to optimize cost control, and because the price of construction projects under the impact of the law, only full compliance with the market price mechanism, based on market laws of supply and demand and price in order to do the bidding phase of Cost Management.

The establishment of a fixed list of library business enterprise should combine their technical and management level to establish their own quotas to reflect the ability of their enterprises, as companies have different levels of Technology and management level of leading enterprise fixed gap, to be followed during the preparation of the relevant provisions of national and industry principle, the specific implementation of the Amendment Act can be fixed, empirical statistical methods, assay methods such as field observation, and ultimately to the actual situation with their own bill of quantities and specifications based on internal corporate fixed.

Establish cost index analysis subsystem. Cost index to reflect the project cost form of technical and economic data, including project cost targets and indicators for two categories of quantities, cost index analysis system should have the following functions: cost index inquiry, comparative analysis of construction cost index Each sub-project should reflect some of the items of the contract amount, unilateral cost, Engineering, project quantity indicators should reflect the structure of material consumption indicators, unilateral projects, and average cost, etc., can cost between the different indicators of the project can be compared horizontally analysis, can provide the basis for rapid estimation. making quick estimates of the proposed project can be based on information in the project database to find similar construction cost index cost index, and can find a similar index to adjust the proposed merger after the works by breaking down quick estimate can be used as the basis for internal audit the company into the tender after the preparation of cost targets through the analysis module and the target database index works compared to similar bias, response bias on the base price there is a big re-examination in order to improve the efficiency of [ 3].

1.4 Construction phase optimization
Investment mainly in the construction phase, which also consumes the largest investment stage, the stage is the construction of the project Cost Management programs to optimize stages in the personnel organization should strengthen the division of tasks and functions, from a cost point of view tracking the implementation of construction personnel, and preparation of detailed work plan and the phase of the process; the use of funds should be taken to prepare the way of rational use of program funds to the project cost targets for risk analysis and develop appropriate responses, should control the construction changes in order to avoid a greater impact on the cost of the necessary design changes should be a rigorous review, and continue to look for potential savings of the possibility of funds, and major construction program to make the necessary technical and economic analysis.

Completion of phase 1.5 Optimization Cost Management
Completion of phase Cost Management solutions to optimize Cost Management is to optimize the whole part of the construction phase should first determine the actual cost to determine the scientific review process should be completed and final account settlement that works to guarantee rational use of funds, and completion of the project should be carried out After the related work, the use of statistical forecasting, and comparative analysis of other factors in order to achieve a reasonable assessment of the final stage of the project Cost Management optimization.

2 Conclusion
Construction Cost Management is a set of Technology, quality, management and other disciplines working in one system, its effective management throughout the project construction should be always so with every aspect of construction are closely linked and therefore to require participation personnel duties, proceed from their range of funds for effective control and optimize the use of, and ultimately to achieve the construction and achieved good economic and social benefits.
