Model engineering quantity statistical method based on BIM technology

Abstract

The invention discloses a model engineering quantity statistical method based on the BIM technology. The method comprises the following steps: constructing a BIM design model according to a project to be calculated, and designing an engineering quantity calculation deduction rule according to a specification requirement; modifying the BIM design model according to a project amount calculation deduction rule to form a BIM amount calculation model capable of being used for amount calculation; loading the attribute list and the coding list according to the characteristics of the project to be calculated, and coding the attribute list by utilizing the coding list according to the requirements of the quota specification, so that each attribute in the attribute list is endowed with the corresponding code in the coding list; endowing each component in the BIM calculation quantity model with attributes by using the encoded attribute list; checking the BIM calculation quantity model endowed with the attributes; and performing engineering quantity calculation on the BIM calculation quantity model passing the check, and generating an engineering quantity report. According to the method, the accuracy and the working efficiency of project cost calculation are effectively improved.

Description

technical field [0001] The invention relates to the technical field of model engineering quantity calculation methods, in particular to a model engineering quantity statistic method based on BIM technology. Background technique [0002] Quantity calculation is the core content of the cost work, which takes up about half of the work time of the cost personnel. The main reason is that the two-dimensional plane drawing cannot directly extract the engineering quantity of the project construction, and it needs to be manually measured, calculated and counted according to the drawings. In addition, to ensure the accuracy and accuracy of the engineering quantity calculation structure, designers and reviewers need to spend a lot of time reading drawings, calculations and summarization. [0003] BIM (Building Information Modeling) has many advantages and characteristics such as visualization, coordination, simulation, optimization, and drawing ability. It uses the model to directly ge...

Problems solved by technology

At present, BIM software has the function of engineering quantity calculation, but the content of the output quantity table is relatively messy, and the export format of the engineering quantity table calculated by different BIM software is also different, which cannot be directly read by engineering valuation software such as Glodon , resulting in the separation of calculation volume and calculation price, and the value of BIM software has not really been brought into play
