Terrestrial laser scanning (TLS) technologies are used for “as-built” purposes and serve as important construction quality control measuring systems, helping to document the condition of structures and ensure data analysis. The study compares three TLS specifications, assessing their key parameters and specifications that determine data quality, suitability for a specific engineering application, and applicability in various work environments. It can be argued that measurement accuracy, point density, and registration integration are more important parameters for assessing tolerances with an accuracy of a few mm at a construction site. Therefore, it is necessary to examine secondary parameters as well as advantages and disadvantages. Optimal instruments for terrestrial laser scanning processes were analysed for the new model of a smart construction quality control measures system. This research presents a new model and a framework for selecting TLS instruments in construction processes. Game theory was applied in the selection process, specifically, Wald’s rule and Savage criterion. The normalisation was considered using a vectorial transformation. The calculation process used the program package LEVI 3.0. The calculation results determined the priority line of the alternative. The results were compared and analysed. The developed new model determined that the Trimble X9 is the optimal instrument for terrestrial laser scanning.
