Specifically, the same reference point can be selected on the universal BIM civil engineering platform, and the reference point is the same reference point as the reference point selected in the shifting step S3, so that the whole special-shaped roof model 3 is moved to the original position, i.e., the position shown in fig. 2, so that the concrete overlapping portion of the special-shaped roof model 3 and the column model 4 is deducted during the concrete summary calculation, and the accuracy of the concrete summary calculation is further ensured.
And a civil engineering summarizing step S6, wherein concrete summarizing calculation is carried out on the column model and the special-shaped top plate model.
Specifically, concrete summarizing calculation can be performed on the column model 4 and the special-shaped roof model 3 on the Guangdong BIM civil engineering measurement platform, so that concrete data of the column model 4 and the special-shaped roof model 3 can be obtained.
And a data processing step S7, processing the steel bar data summarized and calculated in the steel bar summarizing step and the concrete data summarized and calculated in the civil engineering summarizing step to obtain a steel bar report of the column model and a civil engineering report of the column model and the special-shaped roof model.
