Terrestrial laser scanning (TLS) technology is a promising tool for digital transformation in the construction industry, particularly for reconstruction, technical refurbishment, and major repairs of oil and gas field facilities. A digital information model (DIM) reconstructed from the TLS point cloud of laser reflections (PLC) enables not only the geometric position of an object in space to be taken into account but also to monitor its technical condition. A current research area is the development of a comprehensive algorithm for DIM reconstruction from the TLS PLC using Russian software. The goal of this work is to implement and test an algorithm for DIM reconstruction for an oil and gas facility from the TLS PLC using «NanoCAD», «ReClouds», «Model Studio CS», and «CADLib» software. The proposed algorithm includes fieldwork – TLS surveys, non-destructive testing of buildings and structures – as well as office work to process the TLS cloud and reconstruct the DIM in Russian software. Based on the experience of using the resulting DIM, practical applications were identified. It was concluded that the DIM of existing building structures and utilities, combined with the PLC cloud, panoramas from TLS points, and a digital elevation model, provide a highly detailed basis for designing facilities in their actual state. This is due to the ability to take into account the accurate geometric position and technical condition of existing facilities, as well as identify conflicts between design and existing 3D models.
