The relevance of this study stems from the growing requirements for geometric data accuracy in BIM-oriented design and installation of transparent building envelopes, as well as the need to reduce costs and minimize errors associated with traditional manual methods of measuring window openings. The widespread adoption of mobile devices with integrated LiDAR sensors creates prerequisites for automating the measurement process; however, their metrological suitability compared to professional laser scanners remains insufficiently substantiated, which hinders the practical implementation of such solutions in design and installation activities. The purpose of this article is to establish the accuracy level of measuring window opening geometry using mobile LiDAR scanners integrated into iPhone/iPad devices in comparison with professional laser scanners, and to scientifically substantiate the feasibility of applying the obtained data in BIM-oriented design and installation of transparent building envelope structures. The research methods are based on theoretical analysis of contemporary approaches to laser scanning, point cloud processing and analysis, utilization of metric error indicators (MAE, RMSE, maximum deviations), as well as comparative analysis of measurement results obtained by different LiDAR systems from the perspective of their suitability for parametrization in the BIM environment. The results demonstrate that the study examined the characteristics of geometric data generation by mobile and professional LiDAR systems, established differences in the stability and structure of point clouds, and proved the dependence of measurement result suitability for BIM modeling on the level of geometric data consistency. Scientific novelty. For the first time, quantitative limits of mobile LiDAR technology application in construction surveying have been established: it was found that such solutions provide sufficient accuracy for rapid surveying and preliminary BIM analysis, but are limited for tasks with minimal installation tolerances and complex geometry, where professional laser scanners remain necessary. Criteria for selecting measurement technologies depending on the specifics of design and installation tasks have been substantiated. Practical relevance. The research results enable optimization of surveying technology selection in construction projects: mobile LiDAR scanners should be used as an element of a flexible measurement strategy that complements high-precision engineering methods. The limits of practical application of mobile LiDAR in design and installation processes have been determined, which allows avoidance of unjustified expenses for excessively precise equipment or risks from using insufficiently accurate measurements. Recommendations for integrating mobile scanning with BIM platforms to enhance the reliability of digital models have been substantiated
