Investment control of water conservancy and hydropower
Abstract: Nature is like a treasure chest, which contains abundant energy, but these energy sources are not inexhaustible. With the rapid development of economy, our demand for energy is getting higher and higher. As a result, there is a serious energy shortage in China and even the whole world, and the energy crisis is getting worse, especially the shortage of water resources. Therefore, it is urgent to strengthen hydropower development, speed up river regulation and optimize water resources allocation. The investment control of the project is also a link in the construction of water conservancy and hydropower projects, which affects the benefit of the project construction. Therefore, while developing hydropower, we should also give consideration to the rationality of capital investment.

Abstract: Nature is like a treasure chest, which is rich in energy, but these energy sources are not inexhaustible. With the rapid development of economy, the demand for energy is getting higher and higher. There is a serious energy shortage in China and even the whole world, and the energy crisis is getting worse, especially in a large number of scarce water resources. Therefore, it is urgent to intensify hydropower development, speed up river regulation and optimize water resources allocation. Project investment control is a part of water conservancy and hydropower project construction, which affects the success or failure of the project construction. While developing hydropower, reasonable capital investment must be considered.

How to make rational and scientific use of hydropower resources and vigorously develop hydropower? This requires us to increase the construction of water conservancy and hydropower projects. While ensuring the quality of the project, we should also consider the cost of water conservancy and hydropower projects as much as possible, that is, the investment of water conservancy and hydropower projects. On the whole, investment in water conservancy and hydropower projects is a comprehensive, policy and professional activity, which runs through all stages of water conservancy and hydropower project construction. It is an economic and technical index that cannot be ignored. However, at present, there are many problems in the investment of this project, such as the final accounts exceeding the budget; The budget exceeds the estimated budget; The budget estimate exceeds the budget estimate, which greatly affects the economic benefits of water conservancy and hydropower project construction.
First, the reasons that affect the economic benefits of water conservancy and hydropower project construction.
As the saying goes, "everything happens for a reason", and there are certain constraints in the construction of water conservancy and hydropower projects. For example, some new projects can't effectively estimate the engineering standards in the investment decision-making stage because they are in a hurry. Therefore, in the process of engineering construction, it often leads to insufficient investment, resulting in a funding gap, and the investment in water conservancy and hydropower projects has soared. At the same time, due to the shortage of funds, the project construction could not be carried out smoothly, and the completion date was delayed again and again. In this way, investors and contractors naturally bear this heavy burden.
"A good beginning is half the battle" is particularly important for the construction of water conservancy and hydropower projects. It's like an outline of an article. Only by listing the outline can the structure or theme of the article stand. In addition, design also plays a decisive role in the project construction cost. Therefore, based on this, we should pay attention to this link of design and do a good job in preliminary design, technical design and construction drawing design. However, at present, the water conservancy and hydropower project construction has not paid attention to and supervised the design work. Most water conservancy and hydropower projects do not implement quota design, and pay insufficient attention to economic rationality and pay too much attention to technical feasibility. Some designers, in particular, have a weak sense of economy and tend to be conservative in the design process. For example, when considering the safety factor of the project, they often use the method of increasing the cross section of the beam and column and increasing the content of steel bars, resulting in unnecessary waste of funds.
In the process of water conservancy and hydropower project construction, due to the excessive pursuit of profit maximization, some contractors have come up with some opportunistic methods to exaggerate or falsely report the project price. From the point of view of supervision, the attention to the quality and duration of the project is relatively high, but the cost control is relatively weak, which affects the expected project cost to some extent.
Second, the effective control of water conservancy and hydropower investment strategy
Investment control of water conservancy and hydropower projects runs through all links of the whole system engineering, including investment decision-making, design, contracting, construction and completion. Therefore, as investors, we must strengthen management, make rational use of manpower, material resources and financial resources, and strive to control the project cost within the expected investment limit to ensure better economic and social benefits.
Project investment decision-making link to control project cost
For water conservancy and hydropower projects, investment decision-making is an important link to control project investment. The engineering cost engineer should comprehensively evaluate the construction scheme of the proposed project on the basis of technology and economy. In addition, on the basis of optimizing the construction scheme, the investment is estimated with high quality. It can be said that in the process of engineering construction, investment estimation is an effective basis for pre-controlling the total investment of the project. Therefore, it is necessary to strengthen the review of investment estimation so that it can estimate investment completely, accurately and fairly.
Second, the project design link to the project cost control
The design link is an important link in the construction of water conservancy and hydropower projects. Design optimization and economy are very important to the control and management of project cost, which can effectively reduce or control project investment. So how to control the investment in the design process? The main measures are as follows:
First of all, we should review the design budget. If it is found that the design budget has exceeded the approved investment estimate, it is necessary to find the problems in the design in time and find ways to modify the design, so as to effectively adjust the budget estimate and make it more scientific, economical and reasonable. So how to solve the problem? This requires us to put forward practical measures, combine design fees with engineering design cost savings, and implement a series of design reward and punishment systems. In addition, designers who pay attention to cost saving should be rewarded, and designers should be encouraged to actively seek cost-saving and quality-guaranteed design schemes.
Secondly, in the bidding process of design and design supervision, we should also introduce competition and other mechanisms, adopt a preferred attitude towards the schemes put forward by many enterprises, and strive to select the best design scheme to make the building structure and layout more safe, practical, beautiful, economical and reasonable. At the same time, competition mechanism should also be introduced in technical design and construction drawing design, so that each design stage can meet the investment budget standard. In the design process, design supervision also plays a great role. Through his supervision of the design unit, he avoided the conservative state of the designer and effectively controlled the design budget.
Finally, in the design process, effective quota design should be implemented to control investment as much as possible. Designers should master the design principles, various economic indicators and scheme comparison in the preliminary design stage. Effectively control the design cost within the limit, and the construction drawing design should also follow the expected design and control the input of engineering quantity. In addition, designers should actively participate in the design process, at the same time, they should strengthen their own economic awareness and fully control the project cost.
Three, bidding, bidding link control project cost
The bidding pricing procedure for water conservancy and hydropower projects is a pricing method that takes the contract price as the construction project price. This pricing method requires us to strictly examine and evaluate the bidders' quotations, which determines whether the bidding of water conservancy and hydropower projects can meet the expected standards and is also the key factor to effectively control the project cost. In this link, the project owner must understand the calculation method of the bidder's bid quotation and conduct on-the-spot investigation on the construction unit when necessary. For the reasonable low price of the project, the construction party should keep in mind to avoid speculative monopoly by the bidding unit. In the process of signing the contract, we must be careful to put pen to paper, so as to avoid "a slip of the pen will last forever"
Fourth, the construction link of project cost control
In the process of engineering construction, engineering investment is the most affected. It can be said that in this link, the possibility of investment waste is the greatest. Therefore, in the project construction stage, the construction party should not only strengthen the management of contract and project settlement, but also strengthen the management of the construction site, so as to avoid the waste of such investment.
The change of engineering quantity is a common problem in engineering construction. On the one hand, it is due to poor design review, on the other hand, it may be caused by natural and social reasons. Engineering variables have a certain impact on the project investment, which will make the project investment exceed the expected investment limit, thus causing unnecessary waste of funds. Therefore, this requires the construction party to increase control over this.
5. The control of project cost in the completion link.
The economic benefits of water conservancy and hydropower project construction can be reflected through completion settlement. In addition, through the completion settlement, we can also know the actual cost and investment effect of the construction project. To evaluate the effectiveness of investment control, it is necessary to analyze the final accounts of completion, compare them with the budgetary estimate and budget, learn lessons, sum up experience and accumulate data, so as to improve the investment benefit of water conservancy and hydropower construction projects.
Third, summary:
A serious attitude is the basic quality of workers in all walks of life. In the construction of water conservancy and hydropower projects, designers and builders should take into account the effective control of project cost on the basis of ensuring the project quality, reduce or avoid unnecessary waste of funds, and maximize the investment benefit of project construction funds.
