САЖЕТАК / ABSTRACT:

A large-scale cavern project involving the construction of underground facilities for government use faced significant challenges in spatial accuracy, documentation, and coordination. Traditional surveying methods lack real-time updates and precision in complex subsurface conditions.

To overcome these limitations, “Scan to BIM” technology was implemented, combining high-resolution laser scanning with Building Information Modeling (BIM) workflows. This integration enabled accurate documentation, progress tracking, clash detection, and digital twin generation, enhancing both efficiency and safety in underground construction [Autodesk, n.d.].

2.SOLUTION: PRACTICAL APPLICATION OF SCAN TO BIM

2.1 EQUIPMENT AND WORKFLOW

The project team used the Leica RTC360 laser scanner for rapid and accurate point cloud capture and the Leica TS16 total station to establish spatial control. Point cloud registration and post-processing were completed using Cyclone software, achieving millimeter-level accuracy [Leica Geosystems, n.d.-a]. The data was then integrated into BIM environments to support design validation and decision-making.
