The results of studies of the dependence of the snow load and its security on the altitude above the sea level are presented on the basis of statistical data on the distribution of annual maximums of snow water equivalent obtained at 30 meteorological stations and mountain snow-measuring routes of the Krasnodar region and Adygea. Calculated relations are proposed for determining snow loads with arbitrary periods of one-time exceedance in the flat and mountain zones with altitudes up to 2000 m above sea level.

By centrifuging it is possible to manufacture a wide range of building structures and products from reinforced concrete. Such products have several advantages, being relevant in modern construction, however, it requires careful compliance and quality control of the process. The frost resistance of concrete is one of the main indicators characterizing the durability of such building structures as reinforced concrete pillars of power transmission lines and contact network. The analysis of the literature and a series of experimental studies in the laboratory. The influence of the technology of manufacturing products from heavy concrete on the indicator of their cold resistance has been identified and determined.

The problem of energy saving is one of the most pressing problems of our time. In the Russian Federation, especially in the northern part of the country, the task of energy saving is one of the first places. As you know, the main reason for the increased energy consumption for heating and ventilation of buildings is the low level of thermal insulation of the building envelope. The most vulnerable element for heat loss in buildings are translucent structures, through which more than half of the heat supplied to the building is lost. Thus, to solve this problem, it is necessary to look for ways to increase the resistance to heat transfer of window structures and increase their thermal characteristics. One of the solutions for improving the thermal characteristics of translucent structures is the use of protective and heating films. In this work, we carried out experimental studies of the effect of the heating element on the thermal characteristics of window constructions compared to a window without a heating element.

The paper discusses the integral indicators of the quality or level of contamination of natural waters, allowing for an assessment of their ecological status. It has been established that the criterion for the quality of treated wastewater discharged into a water body is a regulatory allowable discharge, but it is not always possible to calculate it, especially for small rivers characterized by low flow rates of the river runoff compared to the flow of wastewater. An integral indicator is proposed for assessing the level of pollution of wastewater discharged, a formula for calculating it, as well as criteria for assessing the quality of wastewater discharged according to the proposed integral indicator. The method of calculating the integral indicator is based on the assessment of the quality of wastewater discharged in terms of BOD5, dissolved oxygen, and nutrient elements. Using the wastewater discharged from the Novocherkassk wastewater treatment plant as an example, an integral indicator of the level of contamination was calculated, which made it possible to characterize the wastewater discharged as “dirty” and make a conclusion about the need for additional treatment.

Modern construction industry is actively introducing new technologies and innovations in the field of high-rise buildings. This dictates certain requirements for the architectural and design features of the frameworks of buildings and the strengthening of foundations. It is necessary to give sufficient rigidity to the object in order to withstand external loads and impacts. All activities are aimed at ensuring the safety of people staying in a high-rise building. In recent decades, the construction of skyscrapers has increased, and such a notion as progressive collapse has become relevant. Therefore, the article examines and analyzes exactly progressive collapse as a problem requiring attention and a scientific approach to its elimination. The report concludes with some conclusions and recommendations.

Ventilated facades are becoming quite common in Europe and around the world. This type of facade provides good thermal comfort in the room. This article describes the main trends of the development of modern facades. The authors look at the numerous advantages of ventilated facades and their varieties with a double chamber (also named multiple-skin façade) in front of traditional massive facades. There is a wide variety of concepts of facades that provide ample opportunities for the work of architects of various schools and directions. The article argues that the design strategies for ventilated facades should adapt to climatic conditions and take into account local features, such as average annual temperature and its extreme values, solar radiation, humidity levels, in order to minimize building loads and energy consumption. The use of double ventilated facades in the construction of new ones and the re-lining of previously constructed buildings with them contribute to the improvement of the ecological characteristics of the urban environment.

Technical progress makes humanity create new technologies and methods in all spheres of life. Evaluation of property also in there. In current moment there are several methods, which are badly obsolete. For example, there are some cases, when building in decrepit or emergency condition were able to buy in cost several times higher than objective cost. These cases aren't unique. New method of evaluation of property could possibly help if not to stop in all appearing of this cases but less their amount. New method is based on Building Information Model (BIM). This model allow take all needed information about building in the currnet moment of time and see in dynamic, how change different indicators of building. This system can be more useful if it associates some amount of building, which differs indicators of interest building and reflecting effects of that building on themselves. This technology can be looked as Extented BIM. Consideration of implementing BIM in evaluation of property has very perspective vay - this can accelerate the time building can be evaluated, and also it let potential client to see all information about building which he need. This makes process of purchase-sale of property more clear, which, by turn, help avoid conflicts when property being researched before purchasing.
