Abstract

The design of building structures always involves structural analysis and quantity take-off calculations. The difference in software between structural analysis and quantity take-off results in differing outcomes, which can lead to planning cost overruns for buildings. The concept used is Building Information Modeling (BIM). BIM can integrate all the information needed for a building, from modeling and structural analysis to cost estimation, all in one software. BIM can have positive effects such as efficient material usage, faster and easier planning, and timely execution. The BIM-based software used is Revit 2024 for modeling and quantity take-off calculations, followed by structural analysis using Robot Structural Analysis to calculate maximum internal forces. This study employs a quantitative method with secondary data in the form of Detailed Engineering Drawings (DED) and Bills of Quantity obtained from the planning consultant. The aim of this study is to create a 3D building model while calculating the quantity take-off using a BIM approach. The results of the BIM calculations will be compared with conventional calculations, and structural analysis will be conducted to determine internal forces in the building. The research results show that there is a difference in volume and cost estimates for concrete (RAB), where conventional Quantity Take Off (QTO) calculations are 3.81% (6.40 m3) greater than the BIM calculations, while the rebar calculations in Revit are 1.44% (358.21 kg) lower than the conventional approach. For structural analysis using RSA, inputting loads in accordance with SNI 1727:2020 yields a maximum axial force of 591.04 kN on a column, a maximum shear force of 108.75 kN on a beam, and a maximum moment of 103.05 kN·m on a beam.
