ABSTRACT

The construction of modern buildings and infrastructure increasingly relies on construction technology, especially Building Information Modeling (BIM). The implementation of BIM as required by PUPR Ministerial Decree number 22 of 2018 provides efficiency and productivity on construction projects with Autodesk Revit as one of the BIM software. The use of BIM provides benefits such as planning building structural models, calculating work volumes, and detecting clashes between reinforcement. Reog Ponorogo monument and museum building project, with a high level of complexity in the underlying structure. Changes to the substructure such as shifting building points and adding borepile foundations. Because the research object still uses direct observation in the field, the BIM method is used to monitor construction work easily and efficiently. The aim of this research is to model the substructure in 3D using the BIM method, determine the volume of work produced and create as-built drawings for the substructure, thus this research uses the BIM method for each stage. The first step is to carry out 3D BIM modeling using Autodesk Revit software. The result of 3D BIM modeling is the volume of work which is also called the quantity take off. Then 3D BIM modeling is carried out clash detection using Autodesk Navisworks software to determine clashing reinforcement. The research results show that 3D BIM modeling of the lower structure of the Reog Ponorogo monument and museum building using Autodesk Revit 2024 produces 3D visualization and work volume (quantity take off). After modeling, clash detection analysis is carried out on the modeling. Check clash detection on each component, no clashes are found. Thus, the modeling does not need to be changed because there are no clashes between the reinforcement.
