ABSTRACT

The increasing growth rate and complexity of construction projects have driven construction service providers to work more efficiently and effectively, leading the construction industry to adopt Building Information Modeling (BIM) technology. In the highly complex construction project of the Reog Ponorogo Monument Museum, changes in work and new items from the initial plan caused the evaluation of budget, work volume, and reduction of work items, as well as changes in the structural drawings due to initial planning discrepancies with actual site conditions. This study employs the BIM Revit method with data on the upper structure of 14 floors, adjusted to real conditions on-site. The modeling was conducted using Autodesk Revit 2024 to create detailed 3D structural models and detect clashes between systems. The objectives of this study are to analyze clashes using Clash Preventor, determine the work volume (Quantity Take Off) using the BIM Revit method, and understand the stages of preparing As-Built Drawings for the upper structure work. The results of the As-Built Drawing documentation indicate that based on clash detection analysis in Clash Preventor Revit, around six clashes between concrete elements were found, which were subsequently rectified to zero clashes. The work volume for the upper structure obtained was 631,824.58 kg of reinforcement, 19,652.93 m² of formwork, and 3,331.44 m³ of concrete. Volume validation showed a deviation of 0.40% for reinforcement, 0.02% for formwork, and 0.00% for concrete. The stages of preparing the As-Built Drawing document began with creating project files, grids, and levels, followed by modeling the upper structure to obtain the work volume, which included modeling columns, beams, slabs, stairs, and shear walls with detailed reinforcement information. The As-Built Drawing document is used for operational control and project maintenance to ensure it aligns with the building projection and remains relevant in the future.
