Engineering project division method capable of quickly and accurately carrying out valuation

Abstract

The invention relates to an engineering project division method capable of quickly and accurately carrying out valuation, and belongs to the field of engineering project management. Engineering project composition entity materials are subjected to classification and division, and the "quantity" and the "price" of the division contain all factors including a structure position, engineering materials, a construction scheme, construction management and the like; a coupling algorithm and a database corresponding to the "quantity" and "quantity" as well as the "quantity" and "price" of the traditional division of the same type of finished engineering project in a place where the engineering project entity material division and engineering projects are positioned are established, and the automatic mathematical statistics and the intelligent data mining of the "price" of the entity material division are realized; the engineering project preliminarily designs an estimate budget and a production drawing budget to carry out comparison and verification on the measurement value of the "price", practical generation values including bid price, settlement price, final settlement price and the like in bidding and tendering and the statistic value of the "price" to realize the utilization and the verification of the "price" in a basic construction whole process including the estimation value in a decision stage, the measurement value in a design stage, the practical value in a construction stage and the like, the "quantity" of an entity (material) subitem is automatically realized by a BIM (Building Information Modeling) model, and the quick and accurate valuation of the engineering project is realized.

Description

technical field [0001] The invention relates to a project sub-item method capable of fast and accurate valuation, in particular to a fast and accurate valuation method for sub-projecting based on physical materials constituting a project project, and belongs to the field of project management. Background technique [0002] The division and sequence of each stage in the entire construction and operation process from decision-making, design, construction to completion acceptance, delivery, operation management and maintenance of engineering projects is called capital construction procedure, and its process is determined by the objective laws of capital construction ( Including natural laws and economic laws), strictly restricted by natural conditions such as geology and hydrology and material and technical conditions, and requiring construction and management according to the overall design that meets the established needs and has scientific basis, generally divided into decisi...

[0004] In the decision-making stage, the method of using macroeconomic indicators to quickly evaluate is to quickly count the amount of macro indicators such as construction area or highway kilometers after the construction scale of the project decision is determined, and apply the statistics of the macro indicators of similar projects in the project location to the investment in the project. Although necessary adjustments and corrections will be made to the investment amount according to the engineering attributes of the project when applying the statistical values ​​of the macro indicators of similar projects, it is impossible to have exactly the same investment amount at the same time where the project is located. Engineering projects, so this method is mainly to reflect the speed, it is difficult to take into account the accuracy

[0005] In the design stage, the project list of bidding and the cost analysis method of the bill of quantities is to calculate the engineering quantity of each calculation sub-item according to the provisions of the engineering quantity measurement rules of the estimated budget project list or the calculation rules of the bill of quantities after the engineering project has a clear design chart , and then apply the applicable quota to analyze the cost and investment amount of each sub-item of the engineering project, a method of calculating and analyzing the cost, and calculate the engineering quantity according to the design chart, the measurement rule of the bill of quantities or the calculation rule of the project quantity calculation rule of the estimated budget item table. This is a very strict, delicate, time-consuming and labor-intensive work, and a cost engineer with high professionalism must be competent for this job. Therefore, although this method of cost analysis is accurate, it is difficult to achieve it quickly.

[0006] Due to the complex inclusion, crossover and interlacing relationship between indicators and sub-items and the content of "quantity" and "price" between sub-items, it is difficult for these two methods to be completely unified and mutually verified, resulting in the final account exceeding the budget, the budget exceeding the estimated budget, and the estimated budget. Three over-estimates and other phenomena often occur and make investment out of control
