Abstract
The Directorate General of Highways in 2021 described the use of Building Information Modeling (BIM) as a mandatory requirement in road and bridge projects. The many BIM software options have caused uncertainty among construction companies, especially in the context of accuracy testing. This study aims to test the Quantity Take-Off (QTO) accuracy of three BIM applications (Autodesk Revit, Nemetschek Allplan, and Tekla Structures) with conventional methods on the Gadang 2 Bridge. The research methods include preparation, data collection, modeling and reinforcement, QTO calculation, and data analysis using Z-score, Bland-Altman plot, ANOVA, and Mean Absolute Percentage Error (MAPE). The results of the Z-score analysis showed that all values were below the threshold of 2, with no significant outlier data. Bland-Altman plot analysis indicated that the differences between the methods were within the specified limits of agreement. ANOVA results showed no significant difference between the tested methods. QTO accuracy, based on MAPE, was 0,018% for Autodesk Revit, 0,043% for Nemetschek Allplan, and 0,046% for Tekla Structures on concrete volume; 0,457% for Autodesk Revit, 0,962% for Nemetschek Allplan, and 0,965% for Tekla Structures on reinforcement. The QTO for Unibridge and Elastomeric bearings showed a MAPE of 0,000% in all three BIM applications. The difference in accuracy is due to the way the applications treat the reinforcement radius and the application's default feature of limiting the reinforcement hook length.
