Recently, research on the use of Building Information Modeling(BIM) for various construction managementactivities is being actively conducted, and interest in 3D model-based estimation is increasingbecause it has the advantage of being able to be automatically performed using the attribute informationof the 3D model. Therefore, this study aimed that the difference in the quantities is calculatedthe quantity based on the 2D drawing of a building and is extracted from the 3D model created by theRevit software was compared and tried to find out the cause. The difference in the quantity calculatedby the two methods was the largest in the formwork, followed by the smallest in the order of thequantity of rebar and concrete. The reason for this difference is that there is a part where the quantityextraction in the 3D model is not suitable for the quantity calculation standard, and in particular, in thecase of formwork, it was difficult to separate only the quantity of the necessary part. In addition, sincethe quantity of rebar was not separated by member, it was impossible to accurately compare thequantity and identify the cause of the difference. Therefore, it is considered to be the most reasonableto use application software that imports only the numerical information necessary for quantitycalculation from the 3D model and applies a separate calculation formula |
