Description

Technical Field

[0001] This invention relates to the field of engineering cost estimation, specifically to a progressive calculation method and system for the differential rate of two types of costs in engineering cost estimation. Background Technology

[0002] In calculating the total investment of a construction project's budget, construction and installation costs are calculated based on the nationally stipulated pricing quotas and bases. Other construction costs (commonly known as "Category II costs") are calculated based on the construction and installation costs, or the sum of these costs and a portion of other construction costs, at a certain rate. However, many of these costs are calculated using a progressive differential rate based on the construction and installation costs or the sum of these costs and a portion of other construction costs, such as project bidding agency service fees, engineering design fees, engineering cost consulting fees, and project construction management fees. Therefore, it is necessary to list the calculation formulas for each interval and then summarize them to obtain the final result.

[0003] The "2021 Budget Quota - Construction and Installation Compilation Method" stipulates that the total project investment approved by the project approval department (approved dynamic investment, excluding project construction management fees) is used as the base for calculating costs incurred in obtaining or leasing land use rights, such as land acquisition and relocation compensation, and is tiered (progressive differential rates). The calculation method is shown in the table below:

[0004]

[0005] Following the calculation steps and formulas above, any given total project budget requires segmented calculations, which are then summed to arrive at the final result. Let's assume the total project investment (excluding land acquisition and compensation) is H ten thousand yuan, and the second category of project budget costs is K. Based on the data in the table above, the calculation rates for each investment segment (above 100,000, 50,001-100,000, 50,001-100,000, 5,001-10,000, 1,001-5,000, below 1,000) are 0.4%, 0.8%, 1.2%, 1.5%, and 2.0%, respectively.

[0006] Therefore, the above calculation method requires tiered classification, separate calculations using different rates, and then summation. The calculation method is complex and has low accuracy. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the existing technology, the purpose of this invention is to provide a progressive calculation method and system for the differential rate of the two types of costs in engineering budget, which solves the problems of complex calculation methods and low accuracy of the two types of costs in engineering budget in the existing technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A progressive calculation method for the differential rate of two types of costs in an engineering budget includes the following steps:

[0010] S1. Establish the calculation formula for Category II costs in the project budget. The calculation formula is as follows:

[0011] K=(H-100001)×(H-100000)×0.4%+(H-100001)×50000×0.8%+(E-50000)×(H-50001)×0.8%+(H-50001)×40000×1%+(D-10000)×(H-10001) ×1%+(H-10001)×5000×1.2%+(C-5000)×1.2%×(H-5001)+(H-5001)×4000×1.5%+(B-1000)×(H-1001)×1.5%+(H-1001)×1000×2%+(HA)×2%;

[0012] Among them, K-Project Budget Estimate Category II Costs, unit: 10,000 yuan;

[0013] H - Total investment amount for the project, in ten thousand yuan;

[0014] A, B, C, D - The number of values ​​that can be taken under specific conditions;

[0015] 1000, 1001, 5000, 5001, 10000, 10001, 50000, 50001, and 100000 represent the range values ​​for the interval-based fee calculation of the total investment amount of the project.

[0016] 2%, 1.5%, 1.2%, 1%, 0.8%, and 0.4% are the corresponding rates for management fees within each range.

[0017] S2. Obtain the total investment amount H of the project;

[0018] S3. Match the obtained total investment amount H of the project with the data taking conditions in the formula for calculating the second type of cost, and take the data for A, B, C, and D in the formula;

[0019] S4. Substitute the determined values ​​of A, B, C, and D into the formula to calculate the second category of project cost K.

[0020] Preferably, the two types of fees are categorized based on the total investment amount H of the project and then calculated according to different fee rates.

[0021] Preferably, the method for obtaining numbers from A, B, C, and D in step S3 is as follows:

[0022] S31. When (H-50001), (H-10001), (H-5001), (H-1001) ≤ 0, take the value 0;

[0023] S32. When (H-100001), (H-50001), (H-10001), (H-5001), and (H-1001) are greater than 0, take the value 1;

[0024] S33. When (H-100001) is greater than 0, E = 50000; when it is less than 0, E = H.

[0025] When (H-50001) is greater than 0, D = 10000; when it is less than 0, D = H.

[0026] When (H-10001) is greater than 0, C = 5000; when it is less than 0, C = H.

[0027] When (H-5001) is greater than 0, B = 1000; when it is less than 0, B = H.

[0028] When (H-1001) is greater than 0, A = H; when it is less than 0, A = 0.

[0029] To achieve the above objectives, the present invention adopts the following technical solution:

[0030] A progressive calculation system for the differential rate of two types of costs in engineering budget estimates, based on the above calculation method, includes:

[0031] The storage module is used to store the progressive calculation formulas for the second category of costs in the project budget;

[0032] The input module is used to input the total investment amount H in the calculation formula;

[0033] The calculation module automatically categorizes and calculates the values ​​of A, B, C, and D in the formula after inputting the total investment amount H of the project. At the same time, it automatically substitutes the values ​​of the second category of project cost K into the formula, and displays and stores them.

[0034] Preferably, the calculation module can automatically identify when (H-50001), (H-10001), (H-5001), (H-1001)≤0 and take 0; when (H-100001), (H-50001), (H-10001), (H-5001), (H-1001)>0 and take 1; at the same time, it calculates the values ​​of A, B, C, and D and automatically substitutes them into the calculation formula for calculation.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] This invention provides a progressive calculation method and system for the differential rate of two types of costs in engineering budget estimates. Through a specific calculation formula, by inputting the total investment amount H of the project, it identifies when (H-50001), (H-10001), (H-5001), (H-1001) ≤ 0 and takes the value 0; when (H-100001), (H-50001), (H-10001), (H-5001), (H-1001) are greater than 0 and take the value 1. At the same time, it calculates the values ​​of A, B, C, and D and substitutes them into the calculation formula to finally calculate the two types of costs in the engineering budget estimate. This method only requires a single calculation formula to calculate the required costs at once, without the need for step-by-step classification calculations, making it simpler and more accurate, and worthy of widespread promotion.

[0041] Among them, K-Project Budget Estimate Category II Costs, unit: 10,000 yuan;

[0042] H - Total investment amount for the project, in ten thousand yuan;

[0043] A, B, C, D - The number of values ​​that can be taken under specific conditions;

[0044] 1000, 1001, 5000, 5001, 10000, 10001, 50000, 50001, and 100000 represent the range values ​​for the interval-based fee calculation of the total investment amount of the project.

[0046] S2. Obtain the total investment amount H of the project;

[0047] S3. Match the obtained total project investment amount H with the data extraction conditions in the formula for calculating the second type of cost, and extract the data from A, B, C, and D in the formula; the data extraction method is as follows:

[0048] S31. When (H-50001), (H-10001), (H-5001), (H-1001) ≤ 0, take the value 0;

[0049] S32. When (H-100001), (H-50001), (H-10001), (H-5001), and (H-1001) are greater than 0, take the value 1;
