A Decade of 3D Laser Scanning for Design Information Verification: Lessons Learned from Onkalo
Since 2014, 3D laser scanning has been utilized for Design Information Verification (DIV) activities at the Onkalo disposal facility for spent nuclear fuel in Finland. High-precision static laser scanners are used for initial verification of tunnel sections following excavation, with the 3D model being incrementally updated as construction progresses. Mobile laser scanning is subsequently used for re-verification, enabling efficient detection of changes in the tunnel’s current status relative to the reference model acquired using static scanning.
This paper presents a comprehensive overview of the past decade of DIV activities, outlining the generation of the final 3D model and discussing key results, implications, and recommendations for future applications.
