Energy sustainability of resedential development as the assessment criterion of city energy-system
The article presents the results of a complex experimental-analytical research of residential development energy parameters - survey of construction sites and determination of calculated energy parameters (resistance to heat transfer) considering their technical condition. The authors suggest a methodology for assessing residential development energy parameters on the basis of construction project’s structural analysis with the use of Kohonen’s self-organizing maps (SOM). SOM clustering permitted to divide the housing stock (on the example of Arkhangelsk city) into groups with similar technical-operational and energy parameters. The methodology for index assessment takes into account the synergistic influence of the characteristics of the construction project itself and the area where it is located. It is also possible to measure energy parameters of construction project of each cluster by comparing them with reference (normative) measures and also with each other. 7 clusters are obtained and grouped together by different development strategies (a list of possible reproductive activities): objects with heat losses that meet the standards, in good condition suitable for long-term operation; objects with the greatest heat losses in a satisfactory condition suitable for further operation; objects with high heat losses in unsatisfactory condition. Urban development projects forming a cluster are displayed on a geo-information basis – the heat map. The designed heat map shows the general condition of the area by the level of residential development energy sustainability. It was revealed, the main part of capital construction projects does not meet the requirements of energy efficiency. The design resistance to heat transfer of the residential development cladding (walls) in the central part of the Arkhangelsk is twice lower than the normative value. On the basis of the proposed strategies it is possible to develop targeted development programs for individual areas (for example quarters) taking into consideration the characteristics of the formed residential development aggregate.

Collisions of general utilities designing through the use of BIM-platforms
The construction industry, in which the technologies of information modeling of buildings and structures are actively applied, continues to develop rapidly. New technologies allow us to automatize a large number of design processes, such as formation of project documentation, specifications formation and others. Particularly BIM technologies are needed in the design of engineering systems, because they allow avoiding the occurrence of design errors that involve intersections of the projected objects - collisions. Despite the wide possibilities of modern software systems and the availability of a large number of tools for identifying collisions, the process of finding intersections is far from ideal In the article, on an example of work on an object of an apartment complex, problems are identified and solutions are offered.

Protective coatings of reinforced cooling towers
The technologies of anticorrosive protection used in modern construction of reinforced concrete cooling towers are considered. The analysis of technical and technological characteristics of protective systems of companies Sika, MC-Bauchemie, BASF and Hempel is performed. The calculation of the consumption of materials based on consumption rates from manufacturers and from the method of VGB-R 612 Ue (Germany) was carried out for the constructions of reinforced concrete cooling towers H = 150 m. The choice of recommended options for protective coatings of reinforced concrete cooling towers is made on the basis of an analysis of their technical characteristics, total consumption of materials and cost indicators of the anticorrosion system.

Energy-efficient construction in the climatic conditions of Latvia
The low energy building can be achieved by implementation of energy efficient building envelope as well as energy efficient heating and ventilation systems. In addition use of renewable energy sources allows reach nZEB and ZEB requirements. This paper provides calculation approach and conclusions on necessary insulation thickness for opaque elements. In addition optimal windows sizes, their orientation and thermal properties to achieve low energy buildings standards in Latvian climate is evaluated in this study. This has been done for single family house. Study takes into account specifics of low energy consumption buildings for five largest cities of Latvia located at places with maximally diverse climatic conditions. The paper presents economical and payback time calculations of low energy building constructions and HVAC systems in Latvia.

Ground improvement using stone column construction encased with geogrid
Using stone column to improve weak soil can be considered as an economic and technical viable for construction projects on the soft soil. According to the case history of the stone column it was provided that it is the best way of successful application for foundation of the structure such as, oil storage tanks, raft foundation, earth embankments. It should be noted that through the installation of the stone column inside the soil the lateral confinement offered by the soil around the stone may not be adequate to form the stone column; in this case encasing the stone column by the geogrid can induce the required lateral confinement. Experimental studies in the present work are carried out to investigate the behaviour of the stone column encased with Geogrid, Tests are carried out on a single installed stone column (ordinary and encased) in order to evaluate the effectiveness of the single column on bearing capacity and settlement. It was found that encasing the stone column with geogrid results in an increase in load carrying capacity and reduction in a settlement in comparison with the case without geogrid. By using geogrid, the ultimate bearing capacity increased by 60% compared to that without geogrid and load-bearing capacity increased by 20% for 10 mm settlement. Numerical analysis will be carried out by using PLAXIS 3D to validate the test and to make comparison between them

Model displacements of the dam crest reservoir Sayano-Shushenskaya HPP
Evaluation of the operational reliability of such important structures as the arch-gravity dam of the Sayano-Shushenskaya hydroelectric power station should be based primarily on the research of stress-strain state of buildings and grounds, combining mathematical modeling and statistical processing of field and experimental data. A more accurate account of safety requirements in the construction of the dispatching schedule can be achieved by moving from the set for a certain set of years of a number of restrictions on the levels of filling of the reservoir directly to the indicators of the established dynamic safety criteria. Such an indicator is the size of the radial displacement of the crest of the dam section 33 of the reservoir Sayano-Shushenskaya HPP. It is shown that such a calculation model of radial displacements of the ridge of the Sayano-Shushenskaya HPP dam is necessary, in which only the indicators obtained by water management calculations were used as initial ones. It has been suggested that the size of the dam crest movement over the calculated time interval in different periods of the calendar year may depend both on the static head and on the change in head over the calculated time interval. This assumption was checked on the basis of the analysis of radial displacements of the crest section 33 of the Sayano-Shushensky hydroelectric complex over the years 2001…2016, the model describes the radial displacement of the crest 33 of the section of the dam of Sayano-Shushenskaya HPP, depending on the pressure and change of pressure for the calculated time interval. According to the proposed algorithm, a computer program was developed, and the calculation of the displacement of the crest of the dam Sayano-Shushenskaya HPP for 2001...2016 years (360 intervals). The estimation of accuracy of the received results is given. It is proposed to use the developed model for the construction of dispatching schedules in the development of rules for the use of water resources of the Sayano-Shushensky reservoir on the Yenisei river. The developed model uses only indicators of water management calculations as initial data, which is convenient for operational planning of safe operating modes of Sayano-Shushensky hydroelectric power station.
