[Paper Keywords] water project cost management cost control program
[Abstract] Now, in order to maximize the economic benefits of Investment, the project cost in all sectors of the application is very extensive. The hydraulic cycle length, and high Investment makes the water project cost management and control has entered a new phase for the water project cost management, which raises profound thought, but also raised some challenges, so this article on water Project pre-Investment, decision-making and design, bidding and construction of medium-term, post-completion and acceptance of three major phases to explore all, in order to set out the feasibility of a strong water project cost management and control programs.


Now, in order to maximize the economic benefits of Investment, construction costs in various industries has been very widely applied, among which water project cost in the use of water resources industry has played a huge role, but, due to water projects has a long life cycle, Investment high vulnerability to natural and environmental impact of geological features, making the water project cost management and control of a certain volatility, water conservancy staff need to always pay attention to all aspects of the dynamics, at any time the corresponding solutions and measures, so How to make effective and scientifically to maximize the return water conservancy, water project cost management for the proposed deep thinking and challenges, while this pre-Investment on water projects, decision-making and design, bidding and construction of medium-term, post-completion and acceptance of three major stages to explore all, to derive a water project feasibility and strong cost management and control programs.

An early phase of water project management and cost control
1.1 Investment decision-making stage
Investment relationship with the late stages of decision-making stage can be controlled effectively, so the cost must be on the technical, economic and other aspects of research, to develop the optimal solution to an important basis for decision-making, so the cost should be aware of the following aspects.

First, carefully investigate the resources required for the project and the real basis of environmental factors, and the survey to collate the information and analysis.

Second, Investment in water projects prior forecast, good works must be collected materials procurement, the major materials and equipment and their prices, construction equipment, water and electricity and other basic information.

Third, according to relevant industry information and state, government regulation, effective market forecasts and Investment estimates for the construction of water projects to provide the necessary basis for the same time, the completion of related feasibility study report, for example, engineering to conduct a risk analysis to determine the project's main source of risk and risk-resisting ability, who according to market water project cost forecasts and estimates for project investment decisions.

Finally, in order to prevent blind investment, making decisions, usually a "collective decision-making system", or investors, policy makers and expert combination of the three decision-making.

1.2 Design phase
Design phase of the project cost management should pay attention to technical, economic, practical and design relationships. And now has a market economy, so in order to achieve the rational design and economy, construction units and design units to actively cooperate to avoid the design and construction out of touch, or the construction of a large number of design changes and other issues. Therefore, to control the design phase, generally need to pay attention to these three directions.

First, the use of design tendering exercise to select advanced Technology, engineering, low cost of a more scientific and rational design.

Second, the technical and economic indicators based on the total figure for the preliminary design plan and individual design calculations, analysis, comparison, evaluation, selection is relatively reasonable solution.

Finally, throughout the design phase, the technical and economic unity, carry out "first budget, then plan" approach, the implementation of the design limit, and eliminate some of the design process, "not afterwards, so do not plan to" undesirable phenomenon.

2.1 Bidding Phase
Bidding stage is the key to the whole project cost management, so at the tender stage, the construction contract must be clear and operable, clarity, there are constraints in nature, and with the price, duties, obligations and other relevant statutory provisions.

Among them, the construction contract price includes a fixed price contract, fixed price contracts, adjustable price contracts for the impartiality and seriousness of the tenders are generally of short duration, small-scale construction projects, should adopt the fixed-price contract, duration, scale large construction projects, should adopt the variable-price contract, while the project cost pricing terms include the pricing of the project cost, once signed, is generally not allowed to tamper with them, but because the project construction process diverse and uncertain in emergency situations , want to completely change does not appear impossible, so they agreed to terms on the occurrence of such circumstances in the contract price after the deal with the settlement approach.

During construction, project cost control is the most direct manifestation of the allocation of the project shall control. Therefore, in order to safeguard the interests of both sides to ensure that money supply in the project on time, to ensure the smooth progress of construction projects, allocation of means for projects should be in terms of the total contract price control under the premise of the multi-node control of progress payments, defined the progress of the submission, approved, the allocation of time.

Project construction phase is the phase of the project share the longest stage, mainly investment projects
During the construction phase. Therefore, in order to avoid the waste of investment, in addition to requirements of the construction unit to strengthen contract management of the project cost, pay attention to settlement construction management, construction site management, but also note the following details on the problem.

First, the construction cost of crucial materials prices, the total estimated project cost of about 70%, for the construction process should be strictly in accordance with the construction contract amount of material to determine the price of materials.

Second, the water conservancy construction process is a dynamic process, with the volatility, if not pay attention to the design, the design is prone to change, so the beginning of construction, the design must be strictly off if the prevailing circumstances and design changes; So, to change, there must be the chief supervision engineer, jointly signed on behalf of the design behind the executable unit, and to try to make time for the construction before the design (and some design changes must be approved by the job is not it?.

Third, standardize management of the construction phase of the on-site visa, so as to do with the sign Meanwhile, to the future in order to avoid an adverse impact on the completion of settlement, visa must be the chief supervision engineer, the construction unit representative, the representative of the construction site of Ning co-signed after the entry into force (because of the approved budget constraints, there is also need a visa approved?.

Fourth, the tender side with contractors, suppliers signed a related contract, or sufficient risk premium (now there is a water project called behind in the valuation amount is equivalent to this cost? And other measures to achieve a minimum of water conservancy construction process to avoid the presence or emerging risks.

Late stage 3 water project management and cost control
Stage of completion and acceptance in hydraulic engineering, construction unit will always be speculation of chances, too exaggerated the amount of engineering and engineering difficulties, the project will amount to join a number of trumped-up final settlement, or settlement of the same item repeated this time, the cost must adhere to this principle, act in strict accordance with the construction contract, carefully review the engineering drawings and verify the actual amount, according to engineering data and previously gathered information on the correct calculation of the completion of the project cost, the project settlement, at the same time, must be reasonable to apply a fixed price or selection , note that the nature of expenses, to complete the project completion and acceptance phase cost management and control.

4 Summary
In short, only the implementation of a comprehensive water project cost control, overall grasp the situation, in order to achieve the ultimate goal of cost management and control, while with the water project cost management system to continuously reform and water project cost management has also started moving in international , standardization, and scientific direction. As long as the emphasis on pre-construction investment decision-making and design, to grasp the overall planning and implementation of medium-term, carefully work late, and reasonable cost of hydraulic control and management, will play its biggest water conservancy project makes economic benefits.
