The construction industry at all times was one of the most popular, as it is closely connected with the life of people. The stronger the population of our planet grows, the more it becomes necessary to erect an ever larger number of be it industrial or residential buildings and structures. This article discusses the problems of technical expertise in determining the volume and cost of actually high-quality work performed. The main problem is that most of the works carried out during construction (repair) are hidden and it is not possible to verify them, therefore, the expert in this examination is forced to be guided by the acts of examination of hidden works and the journal of the work. One of the main causes of disputes between the customer and the contractor is the overestimated volume of work performed, as well as poorly executed work.

Organizational and technological modeling as applied to the processes of reconstruction of buildings of higher education institutions is based on the division of models into structural and functional components - a model of the spatial and technological structure and a functional model of the process of reconstruction of a building of higher education institutions. The article discusses the organization of the work site with the technological sequence of the flow of work processes. Taking this into account, graphs of works were compiled by stages, showing the possibility of parallel production of works, as well as showing the necessary work preceding them. Based on this, a conclusion was made about the effectiveness of the application of the methodology of organizational and technical modeling to increase organizational efficiency.

Cities around the world lack land resources, despite the fact that the housing stock is in a state of extreme deterioration. The solution to this problem becomes such a concept as renovation - the process of updating urban space. This mechanism is currently provided for in the Town Planning Code of the Russian Federation, but for a number of reasons its implementation in practice is limited. Renovation is necessary in the prevailing conditions of the modern world in order to adapt the spaces of former industrial zones for their use in an already new format. The vast majority of industrial companies cease to operate within cities, and their territories turn into neglected neglected development, isolated from the urban social environment. The authors of this article reviewed and analyzed the benefits of implementing renovation programs for residents of the Russian Federation.

Currently, special attention is paid to creating a comfortable urban environment, as a result of this there is a need to create projects that contribute to improving the quality of life of the population. In this paper, we consider two subprograms of the Rostov region: "Improvement of public territories of municipalities of the Rostov region" and "Improvement of the courtyards of apartment buildings in the Rostov region", operating under the state program "Formation of a comfortable urban environment." The number of transformed public and house territories from the moment of implementation of these subprograms of the Rostov region is analyzed.

Modern engineering preparation of construction production (IPSP) is a complex integrated system, including the specialized information-analytical complexes, designed solution of a wide circle of problems of simulation and control, storage and processing of normative-technical documentation (NTD) in a variety of formats, formation and management decisions. The necessity to solve the problem of intellectualization of (IPSP) is connected with the fact that mankind has entered into the phase of building the information society, where the most valuable acquire knowledge. Collection of data and knowledge generates information resources, volume and quality of which will determine the competitiveness of not only the enterprises, but also the physical persons.

Describes three стратегиb housing reconstruction of the first mass series: the radical, complex, a conservative. Implementation of the existing strategies is impossible without the development of additional organizational and technological measures (OTM). When developing OTM should be based on the division of the whole complex of works on reconstruction of the separate stages and associated volumes, which can be performed independently and at different times. In a basis of an element-centric approach to the reconstruction should be based on the principle of economic feasibility and interest of all participants in the process of reconstruction. OTM in поэлементном approach to the reconstruction of forming a system of relations, rights, duties and mutual guarantees of the participants, secured by means of linking the investment cycle for reconstruction into a single organizational-technological building system (ОТСС)

The concept of creation of energy-efficient areas in cities in the reconstruction and secondary residential blocks and micro-districts consists in the fact that, in practice, to prove the real possibilities to reduce energy consumption per unit area of housing in the housing and communal sphere in two and more times due to the implementation of the already well-known energy-saving technical tools and solutions, rational use of their possible combinations of the specific nature-climatic and city planning conditions. The creation of energy efficient zones requires a comprehensive consideration of issues and the systematic development of power supply at all stages of production, transportation and consumption of energy from the modernization of the objects of the engineering infrastructure

Is considered the superstructure of attic floors, as the most simple and effective техническиое decision in the reconstruction of buildings of massive series . Considered two variants of the device attics for residential buildings of the first mass series. The superstructure of mansard floors this is a very difficult technical, economic and social problem, and requires a scientific substantiation and consideration of a complex of organizational and technological issues of reconstruction, a detailed examination of each building, thorough comparative analysis of alternative variants of engineering solutions. In each case it is necessary to take into account the totality of the various factors and first of all the social aspects of reconstruction
