BIM component classification coding method and system based on revit

Abstract

The invention relates to a BIM component classification coding method and system based on revit. The method comprises the steps of obtaining attribute information of a BIM component; determining a free code of the BIM component according to a real estate provider project number influence factor, a building design influence factor, a total construction package influence factor and an engineering cost influence factor; determining a fixed code of the BIM component according to the country code, the manufacturer code and the in-plant commodity code; determining a classification code of the BIM component according to the free code and the fixed code; and performing project model management by adopting revit software according to the classification codes of the BIM components. According to theinvention, real estate companies can orderly manage the BIM based on revit of internal projects; the building design institute realizes quick splitting of the BIM model based on revit; a total packageunit is created to realize hierarchical package work decomposition under the BIM model based on revit; engineering cost personnel quickly complete engineering cost calculation work by utilizing a BIMmodel based on revit; and the combination of a BIM technology based on revit, a fabricated building technology and building operation and maintenance management is promoted.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a method and system for classifying and coding BIM components based on Revit. Background technique [0002] In recent years, BIM (revit) technology has been widely used in the field of construction engineering, but it also encountered many bottlenecks, especially in the classification and coding of components. [0003] The current "Categorization and Coding Standards for Architectural Engineering Design Information Models" GB51269-2017 is referred to as "Code Regulations", and the "Code Regulations" have the problems of non-implementability and controversy, insufficient practicability, open source and little continued use value. [0004] The impracticability and controversy of the work: The current "Code Regulations" try to establish a new classification system to code all the things and people involved in the whole life cycle of the building, instead of using the existing...

AI Technical Summary

Problems solved by technology

The reality is that construction engineering materials are constantly updated and iterated with the progress of the times, so theoretically speaking, the current coding method is impossible to achieve the finalization of the results

At the same time, due to the variety and complexity of construction engineering materials, it is difficult to define all building components in a simple qualitative way, but if the rules for defining all building components in multiple qualitative ways are too complicated, it is difficult to achieve the same as other relevant national standards. seam fit

Moreover, different classification methods are full of contradictions and controversies, which also brings great difficulty to the coding work itself.

[0005] Insufficient practicability and open source: The current "Code Regulations" mainly classifies all building materials from the perspective of architectural designers, and is related to the management process of traditional real estate developers, the working methods of traditional engineering cost personnel, the working habits of traditional building operation and maintenance personnel, and assembly methods. The means of construction implementation and the characteristics of BIM (revit) technology are out of touch, and the connection of related applications cannot be smoothly realized

(The mainstream principle of two-dimensional code generation widely used in construction sites and building logistics maintenance work today is to use component family ID numbers, but the disadvantage of this principle is to generate two-dimensional codes based on a new set of logic. In principle, all building entities need to be It can only be realized by reposting the QR code on the component, which brings great inconvenience to the actual work, resulting in its not widely used)
