Development of the information modeling (BIM) conceptusing Big Data technologies for the implementation of the life cycle management system for capital construction of transport infrastructure

. The development of a scientific concept of information modeling in the tasks of managing the capital construction objects’ life cycle is the key to the successful transition of Russian Railways Holding to digital methods of managing and controlling transport infrastructure. The result of the presented complex project implementation will be the scientific basis for the life cycle information modeling concept and information modeling methodology implementation at its stages. Taking into account the rapid increase in the volume of construction information, the development of automatic systems for collecting, processing and storing information, it is proposed to apply Big Data technologies. The project results are planned to be used as a basis for the pilot information modeling technologies’ development at the stages of the railway infrastructure construction objects’ life cycle.


Introduction
The project is focused on the creation of scientific and methodological foundations for solving information modeling problems at the stages of the life cycle of a railway infrastructure construction facility. Implementation of the capital construction object life cycle concept using information modeling is a key and priority task for the economy of the Russian Federation (order of the President of the Russian Federation of July 19, 2018 No.PR-1235 on the transition to a capital construction life cycle management system).
Within the framework of the project, it is planned to analyze the existing technological processes of transport construction, the regulatory and methodological base. On the system analysis basis carried out, to develop a scientific concept of information modeling in the construction of railway infrastructure facilities at the stages of the life cycle. To link the information modeling processes into a single information system, scientific and methodological foundations for data management in information modeling of railway infrastructure facilities at the stages of the life cycle will be developed, including the prospective requirements development for the classification systems for construction information and levels of digital models' elaboration (detailing). Building an integrated (continuous) lifecycle management system for a capital construction facility requires a special approach to the task of ensuring internal and external interoperability with corporate information systems of the Russian Railways Holding and external, including state information platforms. It is proposed to explore the possibilities of intelligent information processing methods, technologies and methods for analyzing Big Data, to ensure prompt information processing and ensure the interoperability of tasks in information modeling at the stages of the capital construction objects' life cycle. Further, it is planned to develop the information modeling methodologies (in fact, a description of pilot technologies) at each stage of a railway infrastructure construction object life cycle (pre-design studies and investment feasibility studies, design, construction, operation, demolition / dismantling and disposal), including the development of new methods of collection and integration of digital information into an information model using Big Data technologies and the economic efficiency of further implementation of the developed solutions.
