BIM technology-based project amount calculation method

Abstract

The invention discloses a BIM technology-based project amount calculation method. The method comprises the following steps of receiving, checking and rechecking a drawing; establishing a BIM three-dimensional model according to the design drawing; carrying out dynamic management on the BIM three-dimensional model; carrying out collision inspection on the BIM three-dimensional model by combining the actual situation of the project; adjusting and modifying the BIM three-dimensional model according to the collision inspection result of the BIM three-dimensional model; customizing a calculation rule in the BIM three-dimensional model; and calculating and summarizing in the BIM software, and exporting a project amount list. By adopting the method, modeling can be completely carried out according to the actual condition of the building engineering, the actual condition of the building structure can be truly reflected, and the engineering quantity calculation accuracy is improved; a calculation rule is customized in BIM software, parameters of each dimension of the component are accurately calculated, and the quality of engineering quantity calculation is improved; the improvement of theengineering quantity calculation quality is of great significance to the result of the engineering cost, and the method has good social and economic benefits.

Problems solved by technology

[0002] The original engineering quantity calculation method is that the budget clerk performs project listing and calculation on paper documents with the help of calculators and other tools based on local quotas. The work efficiency is low, the calculation accuracy is low, errors are prone to occur, and it is inconvenient to adjust. Once adjustments occur , engineering quantity calculation needs to be calculated from scratch

[0003] With the development of computer applications and the promotion of engineering technology, engineering quantity calculation methods such as excel software and graphic calculation software have gradually been developed. However, there are still many problems in these engineering quantity calculation methods, which cannot meet the rapid development of the construction industry. Traditional engineering The main disadvantages of the quantity calculation method are as follows:

[0004] 1. It cannot completely and correctly reflect the deduction relationship between different components, especially the deduction relationship of complex structures, which will cause errors in the calculation of engineering quantities;

[0005] 2. Due to the huge building system, it is not possible to automatically identify and check graphic drawing errors in general graphic calculation software;

[0006] 3. The structure of modern buildings is complex and changeable, and the calculation methods of engineering quantities are also changing accordingly, and the calculation requirements are getting higher and higher, and most software cannot completely customize the calculation rules;

[0007] 4. In the process of engineering quantity calculation, general software cannot realize the visualization of the calculation model;
