BIM project material and project cost statistical method

Abstract

The invention discloses a BIM project material and project cost statistical method. The method comprises the following steps: adding corresponding material attributes to each component of a three-dimensional model; uploading a historical engineering cost list to a material center; collecting engineering cost information; giving a weight value to each construction cost index in the construction cost information, and storing the weight values into a database; processing each engineering component in the database and then constructing a cost model; inputting each component attribute into a cost model to obtain a cost prediction value; and superposing the construction cost prediction values of the components to obtain the final project construction cost. According to the method, the cost modelis constructed in the historical engineering cost list of the material center, the similar cost model is identified by using the fuzzy identification technology and the three-dimensional model is input to obtain the specific cost of the three-dimensional model, the building scheme is modified at any time, the engineering quantity and the cost are output, the advantages and disadvantages of the schemes are compared, and the investment is saved; and the most beneficial and most economical scheme is selected.

Description

technical field [0001] The invention belongs to the technical field of engineering cost evaluation, in particular to a BIM project material and engineering cost statistics method. Background technique [0002] SketchUp is a 3D modeling program for architects, urban planners, filmmakers, game developers and related professionals. At present, in the engineering design of building components, the mass and center of gravity of the engineering materials are generally calculated using the engineering drawings drawn by SketchUp software, and then the calculation is completed by manually counting the volume, density and coordinates of the materials. However, based on the SketchUp software, there is currently no function that can automatically generate engineering quantities for columns, beams, slabs, walls, and stairs through certain functional modules for the field of BIM structural design. [0003] In traditional engineering quantity statistics, cost personnel generally calculate...
