Construction method for civil engineering BIM (Building Information Modeling) work amount model

Abstract

The invention discloses a construction method for a civil engineering BIM (Building Information Modeling) work amount model. The construction method comprises the following steps that: firstly, obtaining or constructing a BIM initial model, wherein all parameterized construction members in the initial model are created through layered modeling; then, according to work amount statistical requirements and demands, carrying out modeling checking on all secondary structures and prefabricated pre-embedded construction members in the BIM initial model, and carrying out modeling on a non-modeled structure and the pre-embedded construction member; and finally, for all overlapped construction members, according to a preset rule, executing deduction processing, and obtaining the civil engineering BIM work amount model. When the embodiment of the invention is adopted, through the execution of a standardized and normalized program constructed by the civil engineering BIM work amount model, secondary modeling does not need to be carried out for the workload, or data loss caused in multiple relevancy processes between design and operand software can be avoided, and the uniform integration degreeand efficiency of the work amount statistics of a full process can be improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering projects, in particular to a construction method of a civil engineering BIM engineering quantity model. Background technique [0002] BIM (Build Information Modeling) is currently the most cutting-edge architectural design method based on 3D solid modeling in the world. BIM provides a large environment for integrating and managing component attributes throughout the life cycle. However, the technology for assigning attributes and managing applications Development and integration in the BIM environment is just beginning. [0003] REVIT series is a three-dimensional architectural design software developed and applied in 2000. It can support all majors in the preliminary design of architectural projects and the full professional BIM design of construction drawings (Revit Architecture / Structure / MEP). It is also widely used in my country's architectural design systems. BIM software. T...

Problems solved by technology

For the first method, since the construction of the BIM model is designed and generated by the designer, it will not fully follow the calculation rules of the "Code for Calculation of Engineering Quantity of Building Construction and Decoration Engineering" with version number GB50854-2013 during construction, so directly from BIM model extraction of engineering quantity data is inaccurate, incomplete and non-standard

In the second solution, the BIM engineering model requires a lot of complicated operations when associating with graphics software, and there is a certain data loss in the engineering quantities produced by the BIM model after the association; after the BIM engineering model is changed, it needs to be re-associated and output.
