This article is devoted to the latest technology of computer-aided design-Building Information Modeling (Building Information Modeling or Building Information Model). It discusses the prerequisites for the emergence of information modeling, describes its advantages and capabilities compared with the traditional two-dimensional design method and are presented in the figures. Currently in Russia there is a problem of introducing BIM. In this paper, we identified the main problem of introducing BIM technologies in Russia, which is associated with a decrease in the productivity of designers when switching to a new design technology, as well as possible solutions to this problem. In addition, the difficulties arising from attempts to move to BIM-technologies are described. The main conclusion is the indisputable advantage of BIM-technologies over 2D design.

The process of the housing stock aging is constant and continuous. Untimely repair of housing significantly increases the risk of accidents. The purpose of the management companies is to carry out a complex of repair works of apartment buildings according to the current quality requirements for the entire period of operation. The real estate, enterprises, organizations owners engaged in the operation and maintenance of housing, are extremely interested to increase the duration of the effective operation period for buildings and structures basing on the system of maintenance and repair of buildings. This system is equally important for each period of the life cycle of the property. In the field of housing and communal services, despite the ongoing reforms, the problem of timely financing of repair works aimed at ensuring comfortable and safe living conditions in accordance with the existing quality standards is acute. In this regard, the development of an effective system of housing maintenance is a priority. The current state and the main prospects of development of maintenance and maintenance of the housing stock during the planning and repair work in apartment buildings are considered. The proposed multilevel structure of the maintenance system and the methodology of evaluation of technical condition of residential properties taking into account the individual characteristics of the object. The method of planning of repair and construction works taking into account organizational and technological reliability is developed. The technique presented in the article allows to improve the quality of management decisions, which in turn ensure compliance with comfortable and safe living conditions and efficient use of financial resources.

The current situation in housing maintenance and utilities sector of Russia has been reviewed. The current state and dynamics of the development of real estate managing companies have been analyzed to identify drawbacks in planning and executing works to provide preservation of real estate items. On the basis of the analysis the conclusion about the necessity to reform the entire system of organization, maintenance and management of residential property has been made and the main areas of research, that is improvement of the methods of planning and optimal administrative decision taking in order to improve the economic efficiency of their activities has been defined. Using the analysis outcome a number of organizational patterns taking into account the character of the development of activities in different organizational-technological situations ensuring preservation of real estate items have been identified. According to the analysis results the influence of changes in specialized team size on the use of their labour potential for different activities providing real estate items replacement has been estimated The presented in the paper analysis of the organizational patterns of change in the level of workers’ labor potential use has allowed us to establish the fact that the most common way to achieve the required level of performance for maintenance, sanitary maintenance and current repair of housing is obtained changing the team size in the process of distribution. The obtained dependences allow us to define two zones of team concentration: the zone of effective change in teams sizes and the zone of inefficient concentration changes. Based on these dependencies, economic-mathematical models have been built; they allow us to establish the fluctuations of the boundaries of these zones, depending on the characteristics of work execution, which will enable managing companies using the data of the research to improve the quality of organization and management of works on real estate replacement. .
