The paper considers an issue of transition to digital management technologies in the field of construction and housing and communal services in Russia, as well as in other countries. An optimization methodology for the application of  the digital  economy  has been developed using  the example of  the existing  real  estate  management  system in the  Stolichny Microdistrict of Izhevsk city (Udmurt Republic, Russian Federation). The existing and developed new projects of digital technologies are described, the introduction of which will increase the efficiency of the construction and operation of residential buildings. A methodology has been formed for creating an optimization mathematical model for managing construction and operation projects of energy-efficient residential buildings. Prerequisites and a scheme for the joint implementation of this model and digital technologies are given to improve the quality of construction and operation of residential buildings. The paper proposes a phased methodology for the introduction of digital technologies in urban planning, as well as in the field of housing and communal services within the framework of the national program “Digital Economy of the Russian Federation”. The advantages of using block-chain technology in the management of projects for the construction and operation of energy-efficient residential buildings have been studied in the paper. The application of the developed methods that meet the needs of participants in construction activities, as well as the housing and utilities sector, will improve the efficiency of not only the management system for the construction and operation of energy-efficient residential buildings, but also the overall effectiveness of the introduction of digital management in real estate. The proposed ABRIS software can be used in housing and communal services to optimize and track the expenditure of resources vital for a comfortable living of the population.

The paper considers application and development of information technologies while carrying out project management in construction. Organizational and technological support of works throughout its life cycle exerts an influence on quality and efficiency of successful implementation of the construction project. In order to achieve the project goal it is necessary perfectly to organize and plan works, distribute roles and responsibilities of the project participants, regulate composition and content of the project documentation. While analyzing technical and economic indices of construction organization activity and management systems operating in these organizations, conclusion has been made that market experience in functioning of operational management systems has not been adequately applied in practice of domestic construction organizations. Thus, introduction of integrated management systems for quality, costs, time parameters pertaining to project construction, their resource support will contribute to improvement of economic situation of construction organizations. The solution consists in application of up-to-date information technologies, maximum implementation of computer systems and programs in the sphere of production, creation of application software. It has been shown that it is necessary to develop a software model that provides a possibility comprehensively to apply information technology tools for monitoring progress of construction and installation works, systematization of information technology application that allow to control key parameters of construction and installation works, improvement of system for providing actual information in project implementation process. An example of complex application of software products Primavera P6 Professional R8.3.2 and ArchiCAD 17.0.0 is given in the paper.

The paper presents results of the study for samples of concrete beams reinforced with fiberglass rebar produced by LLC “KomAR”. The aim of the study is to determine strength, stiffness and crack resistance of beams with fiberglass rebar, various reinforcement schemes and their comparison with calculated data. Tests have been carried out in accordance with the regulatory requirements for a design scheme with two points of load application P1 = P2. The adopted scheme of pure bending is used in the laboratory for informativeness of the obtained results and getting maximum efforts in a stretched zone of bent elements. A comparison has been made of the data obtained as a result of tests with the ones which have been calculated according to the document SP (Construction Rules) 295.1325800.2017 “Concrete structures reinforced with polymer composite reinforcement. Design rules”, this document is based on the design principle of concrete structures reinforced with metal reinforcement. Due to the fact that composite fittings significantly differ from metal fittings in a number of indicators, comparative tests of concrete beams reinforced with metal and composite fittings have been carried out earlier. Data of the investigations are necessary for understanding behavior of structures and possibility of their application in the objects of capital construction. An excess of inclined section strength on the action of transverse forces over an actual one has been revealed when calculating concrete beams according to the I group of limiting states. While making calculations for the II group of limiting states, the need has been revealed to make changes in the procedure for calculating width of crack opening in order to approximate the calculated data to the data obtained as a result of tests and a procedure for calculating deflections.
