Engineering calculation method and system based on BIM technology, computer equipment and readable storage medium

Abstract

The invention discloses an engineering calculation method and system based on a BIM technology, and belongs to the technical field of infrastructures represented by railway engineering. The method comprises the steps of establishing a standard parameter library, and storing geometrical parameter information of a component in the standard parameter library; importing an REVIT model, and analyzing the REVIT model based on the standard parameter library to obtain geometric parameter information of the REVIT model; determining a calculation rule, and calculating and generating an enterprise list engineering quantity; correlating the enterprise list engineering quantity with engineering quantity list decomposition projects in a cost management system; and calculating the quantity of the generated engineering quantity list decomposition items. The system comprises a standard library module, an import analysis module, a first association module, a calculation module, a second association module and a calculation module. According to the method, the calculation efficiency can be improved, the engineering quantity information of the model is quickly obtained based on the BIM model information, and the engineering quantity and the report form required by the enterprise cost management system are generated.

Description

technical field [0001] The invention belongs to the field of infrastructure represented by railway engineering technology, and more specifically relates to a method and system for railway engineering calculation based on BIM technology. Background technique [0002] Building Information Modeling (Building Information Modeling, BIM) is the latest information technology in the field of architectural design, construction and operation and maintenance. All kinds of information are always integrated in a 3D model information database. The design team, construction unit, facility operation department and owners can work together based on BIM to effectively improve work efficiency, save resources, reduce costs, and achieve sustainable development. [0003] Chinese invention patent, publication number: CN105956762A, publication date: September 21, 2016, discloses the method of engineering calculation and pricing based on BIM and cloud platform, which includes the following steps: S...

AI Technical Summary

Problems solved by technology

This scheme is based on the application of BIM technology in the field of industrial and civil buildings, and cannot be applied to the railway and municipal fields; the scheme does not have the entity structure tree, component library, component parameter library, and enterprise cost management quota list library applicable to the railway and municipal fields. Supporting basic data and related relationships

[0004] However, the component composition of railway engineering has the characteristics of linear and strip structure, and the management habit of component tree is obviously different from that of industrial and civil construction projects. The existing software mainly solves the BIM model calculation of industrial and civil construction projects, which is not applicable. Calculation software for railway engineering, such as Glodon calculation software and Xindian (Bimuyun) three-dimensional calculation software, these software mainly include civil engineering calculation, steel bar calculation, electromechanical calculation, steel structure calculation, site layout Calculations and installation calculations, the calculations covered are industrial and civil construction projects, they are not applicable to railway bridges, roadbeds, tunnel projects, there is no applicable calculation solution, and there is no applicable modeling software except REVIT Model calculation of modeling software other than CATIA, BENTLY, etc.
