The main objective of this work is the need to develop a new technology for automated solution of railway design problems in the information and digital environment.For this purpose, the methodology of structural system analysis, the theory of systems, and the principle of decomposition are applied. A brief analysis of the terms related to informatization and digitalization is given, and the interpretation of the concept of “information and digital environment” in relation to the tasks of railway design. The key concepts of information modeling of construction objects in the current regulatory documentation of the Russian Federation, the main qualiﬁcation features and advantages of information modeling technology are given.Based on the results of the analysis of the structure and functionality of existing computer-aided design systems of railways and highways, the sequence of procedures of the existing technology of computer-aided design of roads is determined. The concept of automated solution of railway design problems in the information and digital environment based on the use of information modeling technologies and mathematical optimization methods is proposed. The concept is represented by a functional hierarchical model of a computer-aided design system. For its development, the Data Flow Diagrams functional modeling tool was used.The proposed concept is the basis for the development of a computer-aided design system, which will allow the implementation of a new technology for computer-aided design of railways, reduce labor costs and deadlines for the development of design solutions, improve their quality and efﬁciency.

Currently, in the design and construction of large industrial enterprises, three-dimensional BIM models of buildings and structures are being introduced. This article describes the practical application of the Leica RTC360 terrestrial laser scanner at the industrial site of PJSC Uralkali, Berezniki, Perm Territory, under construction. The purpose of the survey is geodetic monitoring of construction and the implementation of as-built documentation for the sections of heating, ventilation, water supply, sewerage and heating networks of the shaft building No. 2. To bind point clouds to the construction coordinate system and heights, linear-angular networks are created inside existing industrial enterprises using an electronic total station to determine the coordinates and heights of marks for a ground-based laser scanner. The article considers an automatic method and method for registering the best approximation for combining point clouds obtained using NLS with BIM models. As a result, the automatic method is used when there is a building coordinate system on the object under study. The method of registering the best approximation is used when there is only a conditional coordinate system, for example, for control assemblies of metal structures. It is proposed to perform automatic classification of point clouds, both inside industrial facilities and outside. The classification process is based on a machine learning algorithm that relies on calculations using a video card. Ground-based laser scanning was used directly at a real mining enterprise under construction, which allows further geodetic monitoring, creation of as-built documentation and timely detection of deviations from the project using BIM models.
