Abstract:
The method and apparatus used to verify concrete tolerances should be capable of reliably measuring to the specified tolerance or less. The purpose of this article is to provide users with an in-depth review of the data comparison from a live laser scanning event at Geo Week 2023, as well as to help users in selecting a proper laser scanner for concrete tolerance verification.
