“…Э.К. Кузахметова в работах [16,17] обосновывает необходимость нового индивидуального подхода к проектированию земляного полотна дорог, учитывающего в полной мере особенности инженерно-геологических, гидрологических и топографических условий местности на протяжении линейного объекта 10 . Методы геоинформатики и таксономического анализа, предложенные в работе [18], позволяют выполнить линейное дорожное районирование (ЛДР), разделяя проектируемое земляное полотно на характерные участки с относительно однородными параметрами природной среды на основе инженерно-изыскательских работ по трассе дороги (линейно-дорожные комплексы -ЛДК).…”

Introduction. The experience of Russian computer companies in the field of information modelling technologies (IMT) in construction is analyzed. The attention to the role of standardization and classification of construction information (CSI) for coding elements of the digital information model (DIM) at the stages of organizational design and calendar planning is drawn. The specificity of linear objects with respect to the level of elaboration of model elements and their attribute characteristics at different planning levels is noted. Models and methods. The necessity of an individual approach to the decomposition of road structure elements taking into account the complex of natural and man-made factors is substantiated. At different stages of designing the organization of road construction, the timetable with different degrees of detail depending on the design objectives and available information about the object is presented. The parameters of specialized flows of a linear object, limitations and criteria for the optimality of the calendar plan at the design stage of the construction organization (CO) are determined. The level of elaboration of the model elements at the stage of work production by the contracting organization has been increased. The developed algorithm for forming a complex flow graph in the form of a flowchart and a DIM is presented.Results. The use of the method is considered on the examples of structuring the elements of the object and technological processes at the stage of work production by the contracting organization, taking into account different options and schemes for organizing the work of specialized streams. The design results are presented in the form of a calculation matrix, a cyclogram and a Gantt graph in the MS Project program.Discussion and conclusion. The development of the basic information for the model of the calendar plan for the construction of a road at different stages of design in an integrated general data environment is presented. The use of linear road is justified. zoning as a method of decomposition of a linear object at the stages of CAD, POS and work production by the contracting organization. The structural elements of the design at the final stage (work production by the contracting organization) are linear design and technological modules and specialized flows formed on the basis of maps of labor processes of the contracting organization.

“…Для решения данной проблемы в СибАДИ разработан метод линейного дорожного районирования на основе многоуровневой концептуальной модели, построенной по принципу ранжирования доминирующих факторов природной среды: зональных, интразональных, региональных. Математическое моделирование позволяет последовательно осуществлять декомпозицию объекта (трассы дороги) на зоны, линейные дорожные комплексы (ЛДК) в составе зон, участки с региональными особенностями в составе ЛДК [25][26][27]. Метод прошел апробацию в проектных организациях и рекомендован к использованию при проектировании и строительстве дорог.…”

The relevance of combining BIM information modeling technology and digital twin technology into the SIM-AD information modeling system for managing the construction and operation of roads throughout the life cycle is substantiated. The key provision of this new digital technology is to provide bidirectional communication between a real physical object and a virtual object - its digital model. Throughout the life cycle of a highway, a large amount of information is developed and stored, however, due to its disunity and insufficient level of intellectual support, asset management decisions are not always adequate and timely. One of the hard-to-solve problems of automating the design of transport facilities is the complexity of a formalized description of the processes of interaction between elements of a road structure and changing natural and climatic factors at a linear facility. The developed scheme for including the method of spatial zoning of the road route based on complex engineering surveys in SIM-AD allows you to create a digital twin model with the decomposition of the object into design and technological modules, which more reliably take into account the influence of natural polystructures on the elements of the road structure. Digital twin instance models are designed to record the current state of the operated object and environmental parameters based on sensors installed in the same type of linear and lumped design and technological modules. Systematic diagnostics and accumulation of statistical information on the mutual influence of building elements and environmental factors will serve as the basis for planning effective measures at the stages of maintenance, repair and reconstruction of roads.

The article highlights the peculiarities of the information modeling during the design of the construction of facilities of different types comprising the overall system of the development of cluster sites at oil and gas fields. Project management software (MS Project, Oracle Primavera and similar ones) do not fully solve the problems of design solution optimization for different types of construction facilities. The method proposed is based on the staged generation of the integrated project model. Block diagram of the information modeling algorithm is provided. At the first stage local models are selected and calculated based on the specific features of the three organization forms of the facilities: linear, site, industrial building and units. As applicable to the linear facilities (motorways, pipelines) structure-modular approach enabling implementation of the design and technological solutions based on the environmental situation along the structure length. For the site facilities and industrial buildings matrix models are recommended (critical path analysis, continuity of the resource utilization and work scope). The integrated schedule at the second stage is provided in MS Project. At the third stage probabilistic prediction of the construction timelines by means of simulation modeling in MS Project is performed. An example of the method practical implementation is provided. Information modeling technology development aimed at the construction information model visualization is provided.
