Perbandingan Quantity Take Off Menggunakan Metode Building Information Modelling (BIM) dengan Software Archicad 28

Abstract

Modern construction projects face increasing complexity, highlighting issues of inefficiency and potential inaccuracy in material quantity calculations using conventional methods. This research aims to compare the efficiency and accuracy of Quantity Take Off (QTO) between the Building Information Modelling (BIM) method using Archicad 28 software and conventional methods. Utilizing a hypothetical project as a case study, this research adopts a comparative quantitative approach. Quantity data for structural (coloumn, beam, and slab) were calculated both manually and automatically using Archicad 28. The results indicate that using Archicad 28 for the QTO process significantly improves speed and accuracy compared to conventional methods, reducing the potential for human error and providing more consistent data. Nevertheless, initial BIM adoption requires an investment of time and resources for training and adaptation. These findings suggest that BIM with Archicad 28 is a superior solution for project quantity management. For future research, it is recommended to expand the case study to larger-scale real projects, consider factors such as interoperability between BIM software, and analyze the overall impact of BIM on project management, including cost and time aspects in greater depth.
