Description

Technical Field

[0001] The present invention relates to the technical field of building engineering quantity calculation, and in particular to a virtual fine decoration rapid quantity calculation method and system based on a Revit scheme model. Background Art

[0002] Under the EPC contracting mode, in addition to the basic civil engineering quantity information, the cost specialty needs to provide fast and accurate interior decoration engineering quantity information in the early stage of bidding and tendering to enhance the economy and rationality of the enterprise's bidding and tendering decisions. In the early stage of the project, the cost specialty cannot obtain the interior decoration model, but needs to provide the interior decoration engineering quantity information. Currently, there are the following two methods for statistics in engineering practice: One is that cost personnel conduct manual measurement item by item according to the different practices of room functions and their components such as walls, ceilings, skirting boards, and floors, which has disadvantages such as low work efficiency, high error rate, and easy omission of items. The other is to automatically generate rooms through BIM software plugins, such as the "rough interior decoration" function in Olive Mountain based on the Revit platform, which realizes the automatic creation and quantity calculation of wall finishes, column finishes, ceilings, ceiling finishes, slabs, and skirting boards. However, since the generated model itself consumes extremely large memory resources and the single-generation time is long. For example, when testing a 5572-square-meter outpatient building, the model generation took a total of 21 minutes and 31 seconds, and the engineering quantity statistics took a total of 3 minutes and 27 seconds. Moreover, once there is an individual room function change, the above steps need to be repeated, greatly reducing the usability of its function, and there are problems of poor overall operation efficiency and easy collapse. Summary of the Invention

[0115] In addition to the cases provided by Revit official, the embodiments of the present invention also conduct engineering quantity measurement for actual engineering projects, and the projects include hospital outpatient buildings, factory workshops, residential basements, and architectural museums. Specifically in practice, the research compares the actual engineering quantity with the engineering quantity obtained by the present invention to verify the reliability of the present invention.

The comprehensive error rate will be further reduced, meeting the requirements of the national specification for the comprehensive error rate of 10%-15% in the estimation and budgetary estimate stages for the cost estimation of conventional buildings.

[0128] Compared with the idea of automatically generating the interior decoration model of plug-ins such as Olive Hill, the present invention directly writes the engineering quantity information into the room attribute list. Taking the outpatient building model of 5572㎡ as an example, the former took a total of 24 minutes and 58 seconds for engineering quantity statistics, while the present invention took a total of 27 seconds, with the efficiency increased by about 55 times.
