The relevance of experimental and theoretical studies of improving the operational efficiency of construction arbitrariness is justified. It is established that the operational efficiency of a construction site depends on many factors. In order to identify the main features of improving the operational efficiency of construction production in this study, we used a computer method of relative distribution of premises and computerized planning of relationships and layout. Some features of the system operation at increasing the operational efficiency of construction production are determined. Based on the conducted experiments, the need for further study of improving the operational efficiency of construction production is justified. Also, on the basis of a number of experiments, the influence of the operational efficiency of construction production on the economic aspect of construction was proved.

The article is devoted to the importance and relevance of the development of underground space, today in large cities there is an acute shortage of areas free from development, as well as the high traffic congestion with personal cars, these and many other problems can be solved through the integrated development of underground space. The classification of underground structures is given. The organizational and technical problems of construction below the zero cycle are indicated. Examples of competent use of underground space in the world are considered. Benefits of construction below zero cycle are also noted. The objects, the construction of which is promising underground, are described. Attention is drawn to the climatic and anthropogenic factors taken into account during construction. In conclusion, the measures that need to be taken for the development of the underground space of our cities are considered.

The article presents an analysis of project management in terms of the construction industry. The specific features of the management of production activities of construction enterprises have been studied and the effectiveness of this management has been determined. The main problems in the field of project management of construction activities are identified, the main of which is the absence in Russian legislation of a single normative act regulating the development and implementation of a project only in the construction sector. The project management methodology was also considered, using the example of the American methods PMBOK and PRINCE2. The authors analyzed the statistical data of domestic companies involved in the development and management of projects in various industries. The results of the study showed that Russian construction companies are not actively involved in project management compared to organizations in other areas of activity.

The article is devoted about the importance and urgency of the problem of reconstruction of healthcare facilities, since hospitals, like other forms of ownership, accumulate moral and physical deterioration and need periodic repairs or full-scale reconstruction. In our country, it is not uncommon for a hospital to be a dilapidated building whose service life is coming to an end. That is why in our days the issue of full-scale reconstruction of healthcare facilities is so acute. The Ministry of Health of the Russian Federation has developed a number of measures, thanks to which, according to Rosstat, more than 10 thousand hospitals will be repaired by 2024. The authors of the article make a comprehensive assessment of maternity hospitals in Rostov-on-Don, show their layout and fertility chart. The following is an example of the reconstruction of the observational building of the MBUZ. In the conclusion, the results are summed up and the measures that need to be taken for the comfortable stay of people in the hospitals of our country are determined.

The use of renewable energy sources is an integral part of ensuring the engineering safety of buildings and structures. The article provides a brief study of the sources of electrical energy generated by the energy of rivers, dams and thermal energy of the Earth in Iraq, examines the most important rivers in Iraq and their storage in order to maintain a clean environment and simultaneously generate electricity. The results of Iraq's hydropower analysis revealed the need to build dams on the Tigris and Euphrates rivers for water storage and energy production to maintain environmental cleanliness. The study details the benefits of building dams for many purposes, including irrigation of agricultural land, prevention of natural disasters and conservation of the environment.

The article provides information on the use of the geoinformation database of commercial real estate in the city of Rostov-on-Don. The database is designed to store information about commercial real estate with the aim of effectively managing the technical condition of the facilities. The prerequisites for creating a geographic information database was the need to manage the technical condition of commercial real estate of large companies on the basis of an outsourced agreement. The reference-geographic information system of commercial objects can be used for effective management, data processing and optimization of applications.

This article raised the problem of the rapid pace of urban development and the conditions for comfortable living of the urban population. To solve these problems, the concept of “Smart City” was created. "Smart City" is a system that provides a high level of urban life, increasing the profitability of resource use by combining all the services and information systems of the city. The main elements of this concept and their role in the program are shown. There are ways to solve problems due to the implementation of the Smart City program. The question of the need for the growth of smart cities, and also shows the reasons for the long development of cities in this direction. The main ideas of the implementation of the "Smart City" program are described. The basic strategies for the development of "smart" cities in Russia are given.

The paper proposes to perform quality control of the production work on the consolidation of soil foundation with the use of the method. Application of geo-radiolocation sensing allows to specify and complement the results of engineering and geological surveys, as well as capture the changes taking place in the grounds of foundations after work on fixing them. This will provide a comprehensive picture of the grouting in the underlying foundation of the building and provide a reliable and simple quality control work.
