Automatic Construction Quantity Calculation System

The current ways to determine construction material quantities: calculating manually or using evaluation computer software, are time consuming and lack of accuracy. This study proposes an automatic calculation system to compute construction material quantities using a three dimensional architecture model based on CAD image files. The proposed system reduces the errors produced by manual input, increases the accuracy of calculated quantities, and reduces the calculation time. A comparison of the manually calculated quantities and those calculated by the proposed system confirms the accuracy of the proposed system.
