A Case Study on Building Information Modeling of the YT.5 Building at Rajamangala University of Technology Lanna Using 3D Laser Scanning Tools

Abstract

This article aims to present the procedures for applying 3D laser scanning technology combined with Building information Modeling (BIM) to collect data and create a digital model of Building YT.5 at Rajamangala University of Technology Lanna. As an old building without as-built drawings, renovation and repair work is challenging. The use of 3D laser scanning, utilizing the Trimble SX10 and Trimble X7, enables detailed physical data collection through point cloud data. The data is processed using Trimble RealWorks and Autodesk Recap to eliminate unnecessary information and create a Building information Model (BIM) in Autodesk Revit. This model can be used for precise and efficient building renovation and maintenance planning. The research compares data collection using 3D laser scanning with traditional methods, revealing minimal discrepancies. Additionally, 3D laser scanning offers faster data collection and more detailed coverage. The results show that this technology reduces errors, enhances safety, and efficiently saves time and resources for future building renovations.
