Conservation of Balinese Customary Buildings with BIM Technology Approach

Abstract

Digitizing architectural heritage information has become an important task during these past years. However, only a few studies have addressed the digitization of historic building models for conservation and restoration purposes. As historical building conservation began to decline, many historical buildings are being abandoned and converted into modern facilities in response to our changing needs. The conservation attempt can be made simple by utilizing the Building Information Modeling (BIM), and High Definition Survey (HDS) approaches. These technologies are considered brand new in managing important information related to 3D models, providing us with semantic information and accurate information in both position and elevation. HDS data is constructed in the form of point clouds generated by the collaboration of survey equipment such as GNSS, Drones, Terrestrial Laser Scanning, and high-performance computers. Point cloud data is registered, filtered, and georeferenced before using BIM modeling. This study resulted from registering point cloud data with RMSE 3mm and customary semantic information. The BIM model based on accurate point cloud data is expected to be a solution and a reference in carrying out the conservation and reconstruction of historical buildings in the future.
