BIM Automatic quantity calculation method for calculating rough estimate using BIM in construction design stage and information classification system

摘要

The present invention relates to a method of calculating an automatic quantity for calculating an estimate of a building in which a parameter is applied to a building structure object and a finishing site material in a building design stage (plan design, basic design, execution design) (A) an architectural design level for estimating the BIM project estimate, a range and code selection step (S100) for calculating the quantity of building structure objects and finishing site materials; (b) determining whether the building structure object, the building structure object, and the final site material quantity are calculated (S110); (c) calculating the quantity of the building structure object only, calculating the quantity of material through selection of the structural object and applying the parameter, and applying the selected code information (S120); (d) simultaneously calculating the building structure object and the finishing site material quantity, a quantity calculation operation by selecting the structural object and finishing site material and application of parameters, and applying the selected code information (S130); (e) determining whether the BIM model is modified (S140); (f) if there is no modification of the BIM model, sorting the calculated quantity into a common object and an individual object type, and outputting the calculated quantity to an estimate estimate sheet to which a single object is applied (S150); A calculation method and an information classification system.
