How to evaluate the reservoir

Problems needing attention in asset evaluation of reservoir engineering

Verification and calculation of single project quantities (physical quantities).

The replacement cost method is to re-estimate (calculate) the reservoir project according to the actual engineering quantity of the existing project and the current water conservancy quota. It is not a simulation, nor is it a copy of the original engineering quantity. Therefore, when collecting data to verify the number of projects, we should adopt modern construction methods and construction organization design according to the scale of existing projects, so as not to miss items or quantities, classify them into items and verify them one by one. It is practical to eliminate the number of repeated excavation and pouring projects in the original data. It is best to measure according to the actual situation of existing projects, draw physical drawings and recalculate. This workload is large, which accounts for a large proportion of the whole workload of asset appraisal, and it is also related to the reliability of asset appraisal results. So this work must be meticulous and accurate.

After verification and calculation, Baiguishan Reservoir has completed earthwork14,740,300 cubic meters, accounting for 9 1.2% of the original earthwork, earthwork1867,800 cubic meters, accounting for 75.9% of the original earthwork, and 84,900 cubic meters of concrete, accounting for 66.48% of the original concrete.

Determination of resettlement and land occupation compensation

Because of the water conservancy projects built in the 1950s and 1960s, there is a general problem of demarcation. Most of the land within the management scope of water conservancy projects is not requisitioned according to the current standards, which not only causes management difficulties for water conservancy management departments, but also brings new topics to asset evaluation. Some comrades think that this part of the land has not been requisitioned, which is difficult to manage and controversial with local governments. Therefore, it should not be considered in asset evaluation. We don't think this is correct. As long as the land is within the scope of the Regulations on the Management of Water Conservancy Projects promulgated by the state and the province, it should be included in the asset appraisal. Only in this way can we bring some benefits to the reservoir management unit in the future management and correctly reflect the complete replacement price of the reservoir project.

It is verified that there are 4 1.39 million immigrants in Baiguishan Reservoir, and the inundation and project area are 1. 1.625 million mu. According to the policy at that time, this compensation was too low, and according to the Three Gorges and Xiaolangdi immigrants, the compensation for land occupation was too high. Therefore, we made a social survey. According to the current land acquisition policy, the land compensation fee and resettlement subsidy are calculated at 6 times of the average output value of 1.993, 1.994, 1.995 mu, and * * is included in the immigration and resettlement. The average mu is 46 18 yuan, and the average per capita is1297 million yuan, which has been identified by the provincial immigration office and relevant experts. It is considered that this will not increase the reservoir engineering assets too much, which is more in line with the reality of Henan Province.

Calculation of 30% new rate

The selection of innovation rate directly affects the result of asset evaluation of reservoir projects, and is also the key to asset evaluation. Therefore, when determining the innovation rate, it must have sufficient basis, conform to the actual situation of the evaluated project, and be considered together with the reservoir projects in this province. Because hydraulic structures are not exactly like mechanical and electrical equipment and civil buildings in factories, they can be calculated into new rates by simple average depreciation method. Reservoir engineering is composed of several or several single projects with different functions, which work together to form production capacity and benefits. For example, a single project of spillway gate consists of several sub-projects, plus individual differences in completion time, design standards, construction quality, use conditions and environment, use times and maintenance. We adopt the percentile system for individual projects, formulate several scoring and deduction standards by parts, and then take the actual score as the new rate for individual projects. If a single project consists of multiple sub-projects, the innovation rate of each sub-project shall be calculated according to the above method, and the comprehensive innovation rate of a single project shall be calculated according to Formula ③. In doing so, we avoid simplicity and unity, which is a direction. The problem is to formulate a set of easy-to-operate scoring and deduction standards to avoid artificiality and standardize them.

Fourth, the relationship between asset evaluation and economic benefits.

For reservoir projects with good economic benefits, the asset evaluation results should be appropriately improved, while for reservoir projects with poor economic benefits, the asset evaluation results should be appropriately reduced. Economic benefit is not isolated, it is not only related to the comprehensive benefit of the reservoir project itself, but also related to the comprehensive benefit of the reservoir project in the whole province. Therefore, it is more reasonable to combine the asset evaluation of a single reservoir project with the asset evaluation of the whole reservoir project within the province. As far as Baiguishan Reservoir is concerned, if the asset appraisal result is high, the water fee price will be increased to adapt to the current price level. Even if the water fee price cannot be put in place at one time, it will be beneficial to future management. On the other hand, the results of asset appraisal should not be too high. If it is too high, it will inevitably lead to an increase in the annual depreciation rate. In addition, the water fee price can not be put in place at one time, which will turn the originally economically advantageous units into loss-making units, which will inevitably dampen the enthusiasm of the majority of water conservancy workers and cause many unstable factors to the reservoir management units. Therefore, asset evaluation should be closely related to the economic benefits of reservoir projects in order to achieve the expected purpose.

The appraisal of reservoir engineering assets is highly professional and a brand-new job. There is no ready-made appraisal model and experience to learn from, but this work must be carried out. Only by evaluating the reservoir engineering assets can we comprehensively strengthen the management of reservoir engineering fixed assets, ensure the preservation and appreciation of reservoir engineering assets, increase the economic benefits of reservoir management units, improve the management awareness of reservoir management units, and make the water conservancy price charging system adapt to the current price level. Therefore, in order to make the value of fixed assets of reservoir engineering closer to reality, besides the above problems, there are many other problems, such as the relationship between reclamation rate and dam filling quality, and the relationship between reclamation rate and reservoir siltation. These problems need further study and discussion in the future.
