Abstract. Industrial facilities regularly require reconstruction or replacement of individual elements. To solve such problems, design organisations are increasingly using digital 3D models, which are created using data from terrestrial laser scanning, among other sources. s an example, several facilities of “Kazzinc” LLP were examined, covering the entire workflow from field surveys to the final results. During laser scanning, the average error in point cloud alignment was no more than 7 mm, which meets the requirements for data accuracy between stations of no more than 15 mm.The article highlights the advantages of terrestrial laser scanning (TLS), such as high measurement accuracy and reduced human error. The analysis of deviations from design specifications revealed potential conflicts, which helps to prevent delays and additional costs.Despite these achievements, the main limiting factor remains the lack of regulatory and technical documentation in Kazakhstan governing the use of TLS. In conclusion, it is emphasized that the further development and standardization of TLS methods could significantly enhance the quality and safety of engineering works.
