The problem of thermal energy increased consumption for heating residential buildings is identified. The solution of this issue is to increase the thermal characteristics of enclosing wall structures by insulating them with effective heat-insulating materials. The results of a comparative analysis on the quality parameters of building materials used for building envelopes insulation are presented. The data of facade systems multilayer structures models’ thermal engineering calculation are given. The recommendations for ensuring safety and energy efficiency parameters during construction and installation work on the enclosing structures’ insulation are presented.

Article is devoted to the problem of modernization of engineering education in modern economic conditions. This is necessary to provide qualified personnel for the construction industry. The authors considered innovative approaches to the organization of the educational process. They are based on interdisciplinary links of training of engineering and construction contingent in technical universities. And also on the introduction of digitalization in the teaching of disciplines of a natural science profile. We discussed the combination of traditional forms of training with production activities at existing enterprises of the industry. The work justified the relevance of modernization of engineering education, analysed factors that justify its need and ways to achieve the objectives. Studies have been carried out to assess the effectiveness of combining educational processes at the university with production activities at existing enterprises in Rostov-on-Don. To combine training and production processes in the training of qualified civil engineering personnel the structural division of the enterprise was allocated -the construction laboratory. The laboratory fully meets the tasks set by functional characteristics. Special working conditions of factory laboratories at small and medium-sized enterprises were noted. This is due to the difficult modern economic conditions. The main requirements for the personnel composition of factory laboratories of the new formation have been determined. These include depth and versatility of knowledge, non-standard thinking, flexibility in decision-making, interchangeability, readiness to improve knowledge and professional skills. The practical results of the experience of four years of combining innovative modernization of the training process of civil engineering personnel with production activities are presented. At the existing enterprises of the construction industry in Rostov-on-Don. The results confirm the high effectiveness of the proposed events.

Power transmission lines (PTL) are strategic objects, the reliability of which depends on the life support of the country. Most of the currently operated power transmission lines were put into operation in the twentieth century, and by now there is a problem of assessing their technical condition, repairing them, if necessary, and maintaining them in a working condition. Defects that appear during the operation of reinforced concrete elements of power transmission lines have different localization and degree of manifestation, but typical is the destruction of the surface layer of concrete with exposure of rebar, more often at the base of the power transmission line. The aim of the work is to select the optimal composition of the repair mixture based on non-shrinking and expanding cements, ensuring reliable adhesion of the repair compounds to the concrete of the structure, which will restore the bearing and operational characteristics in the repaired reinforced concrete elements of the power transmission line at the design level.

The considered method for assessing the quality of the repair work to restore the rack supports of transmission lines is based on the method of vibration diagnostics. Power transmission line supports with a symmetrical destruction of the protective layer of concrete in the ground in violation of the construction section were chosen as an object. Finite element modelling package Ansys was used in assessing the quality of repair work. The example of evaluating the quality of repair using the relative adhesion defective area design criteria in the analysis of natural vibration frequencies is given.
