Introduction
Digitalization of construction is a difficult problem, which is a whole complex of digital technologies implementation in solving various problems of the construction industry. One of the main directions of digitalization of construction is the digitalization of design, since it is at this stage that the main qualitative characteristics of future construction products are laid.
The existing automated systems for the development of design documentation for the organization and construction technology do not currently provide a further expansion of the capabilities of modern computing technology due to their limitations, inflexibility of "task technology", information isolation, etc.
After the architectural, construction and design stage, a technological process for the construction of the facility is designed taking into account the specific features of the site and the participants in the construction.
The design of the organization of construction production is a whole range of works, the result of which is the organizational and technological documentation containing the organizational and technical conditions for the activities of production units, ensuring the rational use of resources and the release of construction products. As shown in [1], "the organization of construction production should ensure the mutual consistency of all organizational, technical and technological solutions to achieve the final result -putting the facility into operation with the required quality and on time."

Methods
The existing level of digital technologies in the field of design and organization of construction production does not allow talking about solving the problems of design automation. "The software does not meet the needs of the engineering services of design and contracting organizations due to their locality, inflexibility of the" task technology ", software and information dissociation" [2].
"There is also a vacuum in the field of scientific foundations for solving the problems facing the once powerful system of organizational and technological construction design" [2].
By the decree of the President of the Russian Federation of 09.05.2017 No. 203 "On the Strategy for the Development of the Information Society in the Russian Federation for 2017-2030", it is planned to create the so-called ecosystem of the digital economy of the Russian Federation. The introduction of digital technologies, as shown by foreign and Russian practice and theoretical studies, is implemented on the basis of digital platforms that integrate technological processes and form digital service systems served by a new category of business structures in the relevant field -service integrators, their importance in the economic development of the construction industry is significant. degree is increasing, however, the mechanisms and methods of managing such structures and their assessment, as well as network interconnection with other economic actors and other issues have not yet been sufficiently investigated and developed. The mechanism for implementing such a relationship remains insufficiently studied and determines the need for the development of tools for its identification, methods of assessment and management.
According to the estimates of the World Economic Forum, Global Construction 2030 and other events and organizations, digitalization of the economy has enormous economic potential for business and society over the next decade. As at the stage of design and construction of facilities, especially large ones, full-scale digitalization will lead to huge cost savings -up to 1.2 trillion. dollars, and at the stage of their operation -up to 0.5 trillion. dollars worldwide. The Russian Federation recognizes the need to accelerate the digitalization processes in the economy in order to achieve competitive positions and integration in the digital space of the world economy. Today digital technologies are not only a priority for innovative firms, but are a necessity for all enterprises, have become a mass phenomenon, including in the construction industry, without a global network, no successful enterprise can exist. The penetration of digitalization into all spheres of the country's economy is associated with an increase in the level of service potential of socioeconomic systems. The digital economy is impossible without the digitalization of society, business and government at the same time. Back in 2011, the "Strategy for the Innovative Development of the Russian Federation for the Period until 2020" was adopted (Order of the Government of the Russian Federation dated December 8, 2011 No. 2227-r), which states that "... in the range of sectors with the potential for rapid adaptation of advanced technologies, includes ... construction ... ".
Realization of the "potential of the digital economy by directly embedding digital technologies in the economic mechanism of enterprises" will guarantee the competitive advantages of the Russian Federation at the international level [3]. The political decision in this area was made in the Program "Digital Economy of the Russian Federation" (approved of July 28, 2017 No. 1632-r).
Within the framework of the state program of the Russian Federation "Information Society It should be noted that manufacturing enterprises are among the most inert areas that use digital technologies in comparison, for example, with the financial sector, energy, etc. The trend towards digitalization of the economy that has emerged in the world stimulates the production sector, including construction, to actively introduce digital technologies ...
There are known works on the development of the digital economy in Russia, for example, the work of scientists [4][5][6][7][8][9][10][11][12][13][14][15]. The accumulated research experience shows that in the digital economy, the development of an innovative digital environment is a necessity to gain competitive advantages and develop the ecosystem of the digital economy of the Russian Federation.
According to the Strategy for the Development of the Information Society in the Russian Federation for 2017-2030, "multidimensional project management systems integrated with systems for modeling and managing the life cycle of objects of a new level will ensure the required quality of object and process analysis and management decisions, including deployed cost management systems, construction time, investment and project risks. The introduction of project management based on modern information models should contribute to realizing the potential for innovative development of the construction industry. " The draft Strategy for the innovative development of the construction industry of the Russian Federation until 2030 identifies trends in the innovative development of Among the problems affecting the quality of design work, the quality of the developed design documentation and the timing of its preparation, it was revealed, among others, the imperfection of the legal and regulatory framework for the design, the imperfection of the methodology and design technology, including in typical design; -lack of high-quality domestic software for design work, the use of outdated software packages for design work and calculation of estimates; -lack of uniform standards defining the basic standards and design rules using the technology of information modeling of an object (BIM design); -imperfection of mechanisms ensuring the timely inclusion of innovations in the documents of technical regulation of the construction industry.

Results
The lack of regulatory frameworks for the implementation and use of information modeling technologies in design (BIM-design) and, as a result, the impossibility of introducing modern technologies to implement all stages of the project life cycle, makes it impossible to save budget funds at the stage of construction and installation, operation, reconstruction and liquidation of the facility.
Today, automated computer systems are used at all stages of the creation of construction products, for example: Microsoft Project, Primavera, Spider Project, "Hector: designerbuilder", "PLAN 2000 Project Management", "1C: Construction Contractor 3.0. Management of construction production "," MyPrimavera "," ISUP based on Primavera 5.0 "," Altius -Construction management "and many others.
Among the main areas of digitalization abroad, along with robotization, cloud technologies, computers and mobile devices at construction sites, BIG DATA information storage centers, information modeling technologies, which differ significantly from other types of design work, occupy an important place.
If you add additional parameters to the model -time and cost, which allow you to calculate the parameters of construction processes even before starting work at the facility and plan production processes, then this will already be the so-called 5D model, which is designed to optimize the construction process. Or, if you replace any material or product, this replacement will automatically be reflected in the corresponding technical and operational documentation on the drawings, in the appearance of the object and the consumption of resources. It is assumed that solutions based on BIM technology allow you to perform 4D visualization of the construction process, identify possible conflicts in the documentation, determine the estimated cost by option, allow you to exchange with customers and regulatory authorities, optimize processes, reduce material costs, accelerate construction time and save money ... Software solutions that implement BIM modeling in construction can have cloud storage, remote access and include the following most popular: AUTODESK REVIT, Revit Server, ARCHICAD, Tekla Structures, Tekla BIMsigh, MagiCAD, AutoCAD Civil 3D, GRAPHISOFT, Renga Architecture.
Among domestic similar developments, one can cite an example of a project management system for the construction of complex engineering facilities, capital construction facilities Multi-D, developed by the United Company JSC NIAEP -JSC Atomstroyexport. This design technology allows you to effectively manage the budget, terms and quality -the main parameters of design and construction.

Discussion
Since 2019, the Urban Planning Code of the Russian Federation has been supplemented with the concept of "information modeling", and, according to the Deputy Minister of Construction of the Russian Federation D. Volkov, the introduction of BIM "... will help in the fight against administrative barriers, improve the interaction of various parties in construction, and also strengthen cooperation in matters of interstate cooperation".
More and more construction corporations are switching to BIM models: TsNIIpromzdaniy, for example, has begun to develop a construction information classifier for maintaining and generating BIM models, Polis Group is also switching to information modeling, there are other examples.

Conclusions
The scientific and technical hypothesis of the study consists in the assumption of the possibility of increasing the efficiency of organizational and technological design in construction due to its modernization using modern digital technologies.
At the same time, a methodology for the automation of organizational and technological design in construction should be formulated, which ensures the organization of functional subsystems and the solution of the most important problems. The existing design system with organizational and technological documentation can no longer solve the problems listed above. The way out is seen in the creation of new, digital technologies for the formation of organizational and technological documentation.
