A set of mathematical modules was developed for evaluation the energy performance in the research of electrical systems and complexes in the MatLab. In the electrotechnical library SimPowerSystems of the MatLab software, there are no measuring modules of energy coefficients characterizing the quality of electricity and the energy efficiency of electrical apparatus. Modules are designed to calculate energy coefficients characterizing the quality of electricity (current distortion and voltage distortion) and energy efficiency indicators (power factor and efficiency) are presented. There are described the methods and principles of building the modules. The detailed schemes of modules built on the elements of the Simulink Library are presented, in this connection, these modules are compatible with mathematical models of electrical systems and complexes in the MatLab. Also there are presented the results of the testing of the developed modules and the results of their verification on the schemes that have analytical expressions of energy indicators.

This study focuses on assessing the contribution of the passive ground-coupled air heat exchanger system to decreasing the energy consumption of air conditioning and ventilation systems for office buildings in the Latvian climate conditions. The theoretical part of the thesis deals with methods of office building ventilation, supply air preheating and heat recovery as well as particularities of using ground-coupled air heat exchangers, their design parameters and their joint impact on the thermal performance. The engineering project part includes a ventilation system for an office building with an integrated ground-coupled air heat exchanger. By simulating energy consumption of the ventilation system for a duration of one year, the thesis analyzes the contribution of the heat exchanger to the overall energy consumption, which totals 9.53 MWh and 4.02 MWh a year, according to the desired parameters of the indoor climate. The possible alternative heat recovery solutions are investigated to reach by European Regional Development Fund project Nr.1.1.1.1/16/A/048 "NEARLY ZERO ENERGY SOLUTIONS FOR UNCLASSIFIED BUILDINGS".

This paper researches the importance of social responsible strategic planning regardless of the sector and shows research results on the case example of the selected tourism sector, which has economic and employment potential and social and environmental implications. Tourism sector is closely interdependent with transport sector and influences it. Therefore, the more we develop the tourism sector, the more the transport sector is developing as well. Based on Mulej's Dialectical Systems Theory (DST) we found out that enterprises should integrate sustainability and social responsibility into their strategic planning if they want the Earth to survive. This urged the European Union, ISO International Standards Organization, many other organisations and many researchers. To make strategic planning socially responsible, enterprise's governors should request social responsibility in business policy, which represents their governance guidelines and is implemented through the strategies set up by top managers and realised in the basic realisation process – their business operations.

Given paper is aimed at determining factors, which influence leasing infrastructure development. It also examines the possibilities of overcoming infrastructural growth restrictions and barriers to the development of enterprises of industry, and construction sector. The phenomenon of infrastructural changes has been poorly researched economically and institutionally. These are a kind of quantitative and qualitative growth potential for the economy, for short and long-term periods for transportation or energy company and real estate development company.

This article peruses the basics of the controlling system, its functions and structural phases of the industrial companies. The personnel controlling of the industrial companies (for examples transportation or energy company) is examined in detail. Controlling system occurs applicable within various activity fields of an enterprise. Modern approaches of the domestic scholars are inspected. Goals and focuses of the personnel controlling system of the industrial companies have been analyzed. Foremost it occurs crucial to analyze and define the entire labor process to figure out primary requirements issued to the labor and employees. In article is offered the road map to follow to structure the purposes of all management system of personnel in the specific organization - in the transportation or energy company or other enterprises.

Due to the growth of load on automotive roads, modern transportation engineering is in need of efficient paving materials. Runways and most advanced highways require Portland cement concretes. This makes important the studies directed to improvement of binders for such concretes. In the present work some peculiarities of the process of Portland cement hydration and early setting of cement stone with barium hydrosilicate sol were examined. It was found that the admixture of said sol leads to a shift in the induction period to later times without significant change in its duration. The admixture of a modifier with nanoscale barium hydrosilicates increases the degree of hydration of the cement clinker minerals and changes the phase composition of the hydration products; in particular, the content of portlandite and tricalcium silicate decreases, while the amount of ettringite increases. Changes in the hydration processes of Portland cement and early setting of cement stone that are caused by the nanoscale barium hydrosilicates, allow to forecast positive technological effects both at the stage of manufacturing and at the stage of operation. In particular, the formwork age can be reduced, turnover of molds can be increased, formation of secondary ettringite and corrosion of the first type can be eliminated.

Based on the laboratory test results, regression equations having standard cone and concrete strength, to determine the available amount of cement, water and microsilica were obtained. The joint solution of these equations allowed the researchers to develop the algorithm of designing heavy concrete compositions with microsilica additives for road construction.

This article submits for consideration the structuring elements of the "private sector" development system, the so-called architectural heritage of the Russian province [1]. Three types of development, still present in central parts of settlement systems, i.e. parts of historical value, are revealed. Common features of private plot development for the majority of middle-scale and small towns are characterized. Dependence of the types on various factors: ethnical, natural (geographical), economical, is revealed. It is important to determine which buildings are located along the transport arteries. Does it have historical significance and cultural value, since it forms the image of the city. The outgoing line passes, as a rule, through the entire settlement system and leads to the central part. Basic principles of formation of historically emerged development types, such as blocks, streets and side streets, are shown, and also problems needed to be solved by the means of urban planning are generalized and casted.

Lithosynthesis is the new method of technical and geoecoprotective properties improvement for the cement based construction. The point of the method is the reactions in the pores and capillaries of artificial mineral stone. The classification of the reactions is presented and level of the properties improvement is shown. The examples of the lithosynthesis application are shown with geoecoprotective aspect taken into consideration.

The article analyses 2 kinds of properties of silica sol foam concrete: technical and geoecoprotective ones. Foam concrete stabilized with silica sol foam has lower heat conductivity resulting in fuel saving. Foam concrete obtained according to sol absorption technology has lower water absorption and is good enough for blocking to prevent the environment pollution. Pollution blocking can be achieved by two methods. The first method is saturation of an article affected by oil products with silica sol. The second method is to create a special preventive protection using silica sol screen. The article shows geoecoprotective properties of protein foam soil systems.

A theoretical model for the calculation of the heat parameters of locomotive diesel engine cooling system in case of using heating agent bypass between the circuits is represented.

We also examine the issue related to improving the efficiency of PPS through the use of Stokes and anti-Stokes coatings. Analytical expressions are obtained for the voltage value of the photovoltaic cell (PC) at a different distance from the beginning of the cell as well as dependences of the working voltage on the source length.

The article considers the features of the structure and functioning of energy supply facilities for housing and communal services of municipalities with the identification and analysis of problems, substantiates the main directions of improving the organizational and economic mechanism for the development of alternative sources of electricity supply, taking into account modern innovative energy-efficient technologies. The choice of a rational option for electricity supply to settlements and the region is considered on the basis of an analysis of geographical, climatic and socio-economic conditions, as well as engineering and financial opportunities, the availability of trunk, interregional and other networks, the total installed capacity of regional power plants and a set of other technical and economic Characteristics inherent in the region and its municipalities.

The paper presents the results of the investigation aimed at evaluating the content of dust particles PM₁₀ and PM_2.5 in the air of Yessentuki, one of the resort cities in the Caucasus Mineral Waters region. It gives the data on the size distribution and concentration of fine dust in the city atmosphere with regard to the specific features of urban territory zoning, the climatic factors and seasonal changes in the number of citizens as well as to the remoteness from the industrial zone, the intensity of public and transport traffic. The authors show that it is reasonable to use sequences of random values for the purpose of air quality evaluation in various zones of the city in case of the absence of monitoring stations with continuous measurements checking the probability of the standard values exceedance for fine dust content. Similar investigations are carried out in other resort cities of the Caucasus Mineral Waters region.

We observed causes of using fiber in nowadays construction industry and its influence on a final product properties, where the fine-grained concrete basing of repairing dry construction mix was used as a base. However, in Russia we do not have such experience. If we're talking about changes occurring in the fine-grained concrete all of its are known about it, either in concrete, but in dry-construction mixes changes may have another purpose. Advantages and disadvantages of using fiber were oblieved also in that article. The main subject of this research is the influence of fiber on a mechanical properties of fine-grained concrete. The most attention is paid to estimate the influence of a concrete's properties by metal fibers: casting time (initial and final), workability and strength (tensile strength and compressive strength) in this article. The most popular different type of metal fiber compares for its length and width and the optimum quantity of metal component chooses, which will indicate the maximum possible affirmative result of its using. Dependences comparing properties of fine-grained properties with fiber's type, measurements and quantity which show the evident result of researching are discussed.

The stress-strain state of a rectangular slab resting on an elastic foundation is considered. The slab material is isotropic. The slab has stiffening ribs that directed parallel to both sides of the plate. Solving equations are obtained for determining the deflection for various mechanical and geometric characteristics of the stiffening ribs which are parallel to different sides of the plate, having different rigidity for bending and torsion. The calculation scheme assumes an orthotropic slab having different cylindrical stiffness in two mutually perpendicular directions parallel to the reinforcing ribs. An elastic foundation is adopted by Winkler model. To determine the deflection the Bubnov-Galerkin method is used. The deflection is taken in the form of an expansion in a series with unknown coefficients by special polynomials, which are a combination of Legendre polynomials.

The technique of calculation of prestressed reinforced concrete trusses with taking into account geometrical and physical nonlinearity is considered. As a tool for solving the problem, the finite element method has been chosen. Basic design equations and methods for their solution are given. It is assumed that there are both a prestressed and nonprestressed reinforcement in the bars of the trusses. The prestress is modeled by setting the temperature effect on the reinforcement. The ways of taking into account the physical and geometrical nonlinearity for bars of reinforced concrete trusses are considered. An example of the analysis of a flat truss is given and the behavior of the truss on various stages of its loading up to destruction is analyzed. A program for the analysis of flat and spatial concrete trusses taking into account the nonlinear deformation is developed. The program is adapted to the computational complex PRINS. As a part of this complex it is available to a wide range of engineering, scientific and technical workers

An algorithm for scheduling works is developed, in which the priority of the work corresponds to the total weight of the subordinate works, the vertices of the graph, and it is proved that for graphs of the tree type the algorithm is optimal. An algorithm is synthesized to reduce the search for solutions when drawing up schedules of construction and installation works, allocating a subset with the optimal solution of the problem of the minimum power, which is determined by the structure of its initial data and numerical values. An algorithm for scheduling construction and installation work is developed, taking into account the schedule for the movement of brigades, which is characterized by the possibility to efficiently calculate the values of minimizing the time of work performance by the parameters of organizational and technological reliability through the use of the branch and boundary method. The program of the computational algorithm was compiled in the MatLAB-2008 program. For the initial data of the matrix, random numbers were taken, uniformly distributed in the range from 1 to 100. It takes 0.5; 2.5; 7.5; 27 minutes to solve the problem. Thus, the proposed method for estimating the lower boundary of the solution is sufficiently accurate and allows efficient solution of the minimax task of scheduling construction and installation works.

The share of electric transport in Russia is very small. Many cities refuse operation of urban electric passenger transportation. Basic reasons of it are high cost value and expensive operation. In Moscow the emphasis is placed on development of rail electric transport. It provides fast movement and pollutes the city environment less. The Moscow students understand that for an urban transportation ecological compatibility and safety are important but they choose buses and individual cars with the internal combustion engine for daily use. The main criteria of the choice are the speed and comfort. Ecological compatibility of the individual transport costs on one of the last places.

Sedimentary properties territory Tura-Pyshma interfluve, where Tyumen is located are determined by the general course of ancient and especially the newest tectonic movements. Active development of the transport network on the territory of the Tour-Pyshma interfluve has created the need for a contemporary study of regional peculiarities of grounds. This will allow you to create roads with the quality meet the international standards. The use of average values of indicators of the properties of silty-clay soils during the development of the transport infrastructure projects of the city of Tyumen and its environs is ineffective due to the genetic characteristics of the rocks located at the depth of 1.5-5.0 meters. Detailed analysis showed that the studied soil belongs to the covering carbonate loams and clays, differing in its characteristics from loess-like sediments of the European part of Russia. The thickness of the covering rocks is not more than 5 meters. It's low-carbonate, non-saline and often has a layered structure. The upper three meters of sediments contain the minimum quantity of water-soluble salts (dry residue less than 0.1%). Studied covering loams are characterized by favorable physical properties: the density of the bulk and the particle is 1.44 to 1.62 and 2.70-2.78 g/cm3, respectively. Water permeability is high – the filtration coefficient varies from 3.4 to 6.4 m/day, the minimum water velocity observed in the clay types of soil. The presence of sand layers adversely affects the permeability of soil. Therefore, the design and construction of transport infrastructure of the city and the surrounding territories it is necessary to consider regional features of grounds.

The paper discusses the study of atmospheric particulate matter of Bolshoy Kamen town by means of laser granulometry of snow water samples. Snow sampling points were selected close to major enterprises, along the main streets and roads of the town and in the residential area. The near-ground layer of atmospheric air of the town contains particulate matter of three main size classes: under 10 microns, 10-50 microns and over 700 microns. It is shown that the atmosphere of this town is lightly polluted with particles under 10 μm (PM₁₀). Only in 5 sampling points out of 11 we found microparticles potentially hazardous to human health in significant quantities – from 16.2% to 34.6%. On the most territory of the town large particles (over 400 μm) dominate reaching 79.2%. We can conclude that judging by the particle size analysis of snow water samples Bolshoy Kamen town can be considered safe in terms of presence of particles under 10 μm (PM₁₀) in the atmosphere.

The paper discusses the study of atmospheric particulate matter in the small urban settlement Pogranichny by means of laser granulometry of snow water. The atmosphere of this settlement is polluted with particles under 10 μm (PM₁₀) to a certain extent. We found microparticles potentially hazardous to health in significant quantities (from 176.3% to 24.9%) in 4 sampling points out of 9. Large particles (sized over 400 μm) dominate on the most territory of the settlement reaching 78.1%.

The indoor air pollution is analyzed in the article. The subject of the research is the presence and composition of the dust particles taken into "traps" in the working space of the public building (Volgograd State Technical University, Volgograd, the Russian Federation).

Labor connections define the life of the city, the distribution of the centers of gravity, and the functioning of its main subsystems, the leading one being the transport subsystem. A methodology based on the analyzed models was developed to address the problems of forecasting and estimating the location of urban development areas. It is based on the study of human (city population) behavior patterns and the underlying nature of the choice of destinations. This allowed establishing the reason for the said choice and, consequently, the formation and direction of the movement of people and traffic. The study is constructed to reveal the trend of settlement (by labor gravitation) based on the effect of the desired choice of workplace location in relation to residence location. The results of the sociological survey allowed establishing the trend of settlement on the basis of the effect of the desired choice. The study discovered a correlation between the values characterizing the topological structure of the plan: a distinctive "scale of settlement" (average shortest distances between the settlement variant and workplace locations) and the internal heterogeneity of the plan (uneven concentration of facilities and their connections). This allows drafting settlement curves for cities without empirical data.

The article considers the current questions of technological modeling and calculation of the new facility for cleaning natural waters, the clarifier reactor for the optimal operating mode, which was developed in Novosibirsk State University of Architecture and Civil Engineering (SibSTRIN). A calculation technique based on well-known dependences of hydraulics is presented. A calculation example of a structure on experimental data is considered. The maximum possible rate of ascending flow of purified water was determined, based on the 24 hour clarification cycle. The fractional composition of the contact mass was determined with minimal expansion of contact mass layer, which ensured the elimination of stagnant zones. The clarification cycle duration was clarified by the parameters of technological modeling by recalculating maximum possible upward flow rate of clarified water. The thickness of the contact mass layer was determined. Likewise, clarification reactors can be calculated for any other lightening conditions.

Such factors as: the growing deterioration and unsatisfactory technical condition of the pipes of water supply and wastewater disposal networks in Russian cities and other inhabited localities, as well as limited (under the conditions of Russian housing and utilities sector reforming) funding of pipeline renovation and rehabilitation have considerably aggravated the problem of pipe reliability provision. These factors make pipe renovation and rehabilitation quite a topical issue.A very promising trend in the field of pipeline construction and renovation named "trenchless technologies" has been commonly used in the world in recent years. As a result of this, a wide choice of different construction materials used for pipe rehabilitation appeared in the market. Under the conditions of densely built-up urban areas, these methods are of great current interest for city utilities. Quite different pipe renovation methods are used currently but the most popular method comprises the application of a flexible polymeric hose that makes it possible to form a new composite pipe inside the old one. The wall thickness of such a hose is among the important factors that have an impact on the cost and efficiency of pipe renovation methods based on the application of flexible polymeric hoses. The hose wall thickness is determined on the basis of calculating the "soil – old pipe – hose" system in view of its static stability. The article describes the technology for the trenchless rehabilitation of water pipes and the strength calculation method for a "pipe – polymeric hose" double-layer structure.

The BIM technology during her creation has been aimed, first of all, at design and construction branch, but its application in the field of studying and operation of architectural heritage can essentially change and transfer this kind of activity to new qualitative level. The question of effective introduction of BIM technologies at the solution of administrative questions of operation and development of monuments of architecture is considered in article. Creation of the information model of the building object of cultural heritage including a full complex of information on an object is offered: historical and archival, legal, technical, administrative, etc. The 3D model of an object of cultural heritage with color marking of elements on degree of wear and a first priority of carrying out repair will become one of components of model. This model will allow to estimate visually technical condition of the building in general and to gain general idea about scales of necessary repair and construction actions that promotes improvement of quality of operation of an object, and also simplifies and accelerates processing of information and in need of a memorial building assessment as subject to investment.

The specified method efficiency is characterized by the significant reduction of the earth works volume and construction machinery capacity increase.

One of the most important ways of increasing the energy-efficiency of the construction industry is the reduction of the material capacity of structures and labour intensity of their manufacturing. Since manufacturing of reinforced concrete structures requires considerable financial and energy expenses, then reduction of technological cycle operations is sure to be the urgent task today. It is well known, that in the recessed reinforced concrete elements the transverse reinforcement is fixed for the purpose of ensuring the longitudinal rods fixity. Besides, the thickness of the protective layer, as a rule, is taken the minimum. The authors proposed to increase the protective layer, and that will reduce the amount of transverse reinforcement rods significantly and will make the technological process of structures manufacturing easier.

To improve the given situation, it is offered to set a technological normal at the design stage by means of working out the technological maps studying the set and the succession of operations in details, taking in mind the properties of energy-efficient materials. At Don State Technical University (DSTU) the intelligent systems of management are being developed providing organizational and technological and also informational integration of design and production stages by means of creating the single database of technological maps, volumes of work and resources.

Use of recuperator in heat producing plants for utilization of natural gas combustion products allows to achieve the saving of gas fuel and also provides for environmental sanitation. Decrease of the volumes of natural gas combustion due to utilization of heat provides not only for reduction of harmful agents in the combustion products discharged into the atmosphere, but also creates conditions for increase of energy saving in heating processes of heat producing plants due to air overheating in the recuperator. Grapho-analytical method of determination of energy saving and reduction of discharges of combustion products into the atmosphere is represented in the article. Multifunctional diagram is developed, allowing to determine simultaneously savings from reduction of volumes of natural gas combusted and from reduction of amounts of harmful agents in the combustion products discharged into the atmosphere. Calculation of natural gas economy for heat producing plant taking into consideration certain capacity is carried out.

Surface water disposal is one of the most relevant problems for Nizhniy Novgorod railway service enterprises. Waste water must be quickly removed with special drainage devices and water drainage facilities (culverts, slope drains, pipes, ditches, etc.). During "Sapsan"-carriages defrosting watse water is aggregated on railroad tracks. It leads to track bed structure sagging, roadbed washaway and damages to point switches. In this paper the authors describe a concrete system of waste water disposal from railway service enterprises. This system is realized through culverts readjusted at the foot of ballast section. Thereafter, the collected water is pumped into a water collector and to local sewage waste-disposal plants. For railway stations with three or more tracks surface runoff diversion scheme depends on topography, railway tracks types, flow discharge and is compiled individually for each object. This paper examines "Sapsan"-carriages defrosting station of Nizhniy Novgorod railway service enterprise. It presents a technology scheme and equipment consisting of Sand catcher LOS-P, Oil catcher LOS-N, pressure-tight flotation unit; drain feed pump; solution-consuming tank of the coagulant, the solution-consuming tank of flocculant. The proposed technology has been introduced into the project practice.

The paper gives an overview of surface wastewater outlets in Samara through the rainwater sewer system into the Saratov water reservoir and the Samara river. The rainwater sewer system in Samara is designed and executed according to a separate scheme, except for the old part of the city, where surface run-off is dumped into the sewer system through siphoned drain. The rainwater system disposes of surface, drainage, industrial clean-contamined waters, emergency and technology discharges from the city's heat supply and water supply systems. The effluent discharge is carried out by means of separate wastewater outlets into ravines or directly into the Samara river and the Saratov water reservoir without cleaning. The effluent discharge is carried out through the rainwater sewer system with 17 wastewater outlets into the Saratov water reservoir. In the Samara river, surface runoff drainage and clean-contamined water of industrial enterprises is carried out through 14 wastewater outlets. This study emphasizes the demand to arrange effluent discharge and construction of sewage treatment plants to prevent contamination of water objects by surface run-off from residential areas and industrial territories.

The Federal State Statistics Service of the Republic of Tatarstan collected data on registered organizations involved in the fabrication and dyeing of fur. This paper describes wastewater characteristic of an existing enterprise, LLC "Melita". This enterprise is a factory of a complete technology cycle, with the process starting from fur manufacture and design to implementation. Maximum capacity of the factory is 1800 skins per day, (excluding fur), and its average productivity is 1000 skins per day. Thorough examination of possible methods and schemes for wastewater from fur production purification showed that it is most reasonable to use technology schemes which included the structures of mechanical, physico-chemical and biological purification. As a result, the study provided a new technological scheme for industrial wastewater purification. This scheme offers using chloride barium and sodium hydrocarbons complex as reagents. For LLC "Melita", the wastewater absorbing pond is the Volga River. Water quality indicators are taken according to the data of the FGBU "Hydrometeorology and Environmental Monitoring Office". The research also calculates allowable discharge rates and environmental charges in the city sewer networks and ponds.

We consider the calculation of modulation power losses in a system "induction motor–inverter" for various pulse width modulation (PWM) methods of the supply voltage. Presented values of modulation power losses are the result of modeling a system "DC link - two-level three-phase voltage inverter - induction motor - load". In this study the power losses in a system "induction motor - inverter" are computed, as well as losses caused by higher harmonics of PWM supply voltage, followed by definition of active power consumed by the DC link for a specified value mechanical power on the induction motor shaft. Mechanical power was determined by the rotation speed and the torque on the motor shaft in various quasi-sinusoidal supply voltage PWM modes. These calculations reveal the best coefficient of performance (COP) in a system of a variable frequency drive (VFD) with independent voltage inverter controlled by induction motor PWM.

The system contains a discrete stage of reactive power compensation and adjustable part. The adjustable part includes series and parallel reactive power compensators. The series compensator consists of a booster transformer, a voltage inverter and is designed to be switched on to the high voltage of the transformer substations. The parallel compensator consists of a rectifier with an input choke and is connected to the low voltage of the substation. The rectifier and inverter are connected by a DC link with an LC filter. The rectifier regulates the output voltage and the phase of the sinusoidal input current. The inverter regulates the magnitude and phase of the voltage on the control winding of the booster transformer. The rectifier and inverter control systems are synchronized with the network and with pulse width modulation.

The results of long-term studies (1976-2016) of water-physical properties of long-seasonally-frozen peat soils of Northern Trans-Ural are set out. It is shown that the changes in water-physical properties are functional in nature and primarily due to economic use of soil and the condition of its surface. A significant influence on the composition density of peat soils, especially in the first years after drainage, has the process of shrinking. In the conditions of Northern Trans-Ural annual reduction in the value of peat soils is 1.5 cm in the first five years after drainage, 1-1.2 cm for 15 years and 0.6-0.7 cm in subsequent years. In the first five years after drainage, the density of the composition in the layer 0.2 m increased by 7.4%, declining to 2.1-3.0% in subsequent years. At a depth of 0.6-1.0 m in 5 years after drainage there is no significant change of addition density. A significant increase in the density of the addition of peat-gley soil established by plowing underlying mineral soil. A relatively stable indicator is the density of the solid phase of the soil. For 35 years, the density of the solid phase medium peat soil layer of 0.3 m increased by 5.4%; low power over a 20 year period by 1.2%. The least moisture capacity medium peat soil over a 35-year period in the rooting zone (0.3 m) layer was reduced by 11.5%; at a depth of 0.6-1.0 m - by 3.7%. In thin peat soil reduction of water capacity in the layer of 0.3 m in 20 years was 6.4%; in peat (0.2 m) layer of peaty gley soil during the same period - by 10.2%.

The paper analyzes and compares different methods of risk assessment for construction projects of transport objects. The management of such type of projects demands application of special probabilistic methods due to large level of uncertainty of their implementation. Risk management in the projects requires the use of probabilistic and statistical methods. The aim of the work is to develop a methodology for using traditional methods in combination with robust methods that allow obtaining reliable risk assessments in projects. The robust approach is based on the principle of maximum likelihood and in assessing the risk allows the researcher to obtain reliable results in situations of great uncertainty. The application of robust procedures allows to carry out a quantitative assessment of the main risk indicators of projects when solving the tasks of managing innovation-investment projects. Calculation of damage from the onset of a risky event is possible by any competent specialist. And an assessment of the probability of occurrence of a risky event requires the involvement of special probabilistic methods based on the proposed robust approaches. Practice shows the effectiveness and reliability of results. The methodology developed in the article can be used to create information technologies and their application in automated control systems for complex projects.

The paper provides the calculation theory of an arbitrary supported and arbitrary loaded reinforced beam filled with bimodulus material. The formulas determining normal stresses, bending moments, shear forces, rotation angles and a deflection of a rectangular crosssection beam reinforced with any number of bars aligned parallel to the beam axis have been obtained. The numerical study has been carried out to investigate an influence of a modulus of subgrade reaction on values of maximum normal stresses, maximum bending moments and a maximum deflection of a hinged supported beam loaded with a point force or uniform distributed load. The estimation is based on the method of initial parameters for a beam on elastic foundation and the Bubnov-Galerkin method. Values of maximum deflections, maximum bending moments and maximum stresses obtained by these methods coincide. The numerical studies show that taking into consideration the bimodulus of material leads to the necessity to calculate the strength analysis of both tensile stresses and compressive stresses.

Today, when solving the problems of energy supply of buildings, it is important to turn to past experience, to evaluate the effectiveness of solutions that pertain to the period of the formation of an industrial Russian city of the XX century. In this regard, it is important to preserve those objects of industrial architecture that were intended, among other things, for solving problems of energy supply. Even now the architectural legacy of V.G. Shukhov, an outstanding Russian engineer and inventor, triggers discussions and debates. In particular, an impassionate debate arose over the best procedures for the preservation of his architectural works. In the meantime, while debatorslock their horns, the architectural works, designed by this phenomenal engineer and architect, keep decaying. The mission of this article is to assess the impact of the structures, designed by V.G. Shukhov, produced on the conceptual design of an industrial city, and to understand what particular losses the decay of his projects may involve. Another mission, pursued by the author, is to demonstrate the scale of V.G.Shukhov's work performed in the capacity of an engineer and an inventor. The subject of this research is limited to the study of the restoration effort applied to the Shukhov radio and television tower, also known as the Shabolovka tower.

Currently, many building materials for interior finishing are based on gypsum as a binder. Usage of gypsum allows to significantly simplify both the production of building materials and to increase the operational properties related to energy efficiency. This makes important the studies directed to the improvement of gypsum-based binders. In the present work the influence of nanoscale modifiers based on zinc hydrosilicates to the structure and properties of gypsum was examined. The dependence between compressive strength of gypsum and content of the modifier was approximated by a rational function. It was found that the reason for the increase of strength is a change in the structure of the newly forming gypsum; such a change consists, in particular, in the formation of split crystals. At the same time, chemical composition of the nanomodified gypsum remains unchanged. It is shown that the formation of split gypsum crystals is observed when using nanomodifiers that significantly shorten the setting time.

The article highlights the necessity of a complex approach to assess economic security of municipalities, which would consider municipal management specifics. The approach allows comparing the economic security level of municipalities, but it does not describe parameter differences between compared municipalities. Therefore, there is a second method suggested: parameter rank order method. Applying these methods allowed to figure out the leaders and outsiders of the economic security among municipalities and rank all economic security parameters according to the significance level. Complex assessment of the economic security of municipalities, based on the combination of the two approaches, allowed to assess the security level more accurate. In order to assure economic security and equalize its threshold values, one should pay special attention to transportation system development in municipalities. Strategic aims of projects in the area of transportation infrastructure development in municipalities include the following issues: contribution into creating and elaborating transportation logistics and manufacture transport complexes, development of transportation infrastructure with account of internal and external functions of the region, public transport development, improvement of transport security and reducing its negative influence on the environment.

The study we are conducting involves the analysis of information security levels achieved by energy providers operating in the North Arctic Region. We look into whether the energy providers' current information security levels meet reliability standards and determine what further actions may be needed for upgrading information security in the context of the digital transformation that the world community is undergoing. When developing the information security systems for electric energy providers or selecting the protection means for them, we are governed by the fact that the assets to be protected are process technologies. While information security risk can be assessed using different methods, the evaluation of the economic damage from these risks appears to be a difficult task. The most probable and harmful risks we have identified when evaluating the electric energy providers' information security will be used by us as variables. To provide the evaluation, it is necessary to calculate the costs relating to elimination of the risks identified. The final stage of the study will involve the development of an operation algorithm for the North Arctic Region's energy provider's business information protection security system – a set of information security services, and security software and hardware.

The relations to describe the work of the joint have been stated. Boundary conditions for each layer have been formulated. To describe the deformation of the composite coupling with consideration of the composite cylindrical shells theory a mathematical model in the form of a system of differential equations in displacements and boundary conditions has been obtained. Calculation of a two-layer cylindrical shell under the action of an axisymmetric load has been accomplished.

Work is devoted to the solution of problems of energy efficiency increase in low power boilers at combustion of solid fuel. The technological method of nitrogen oxides decomposition on a surface of carbon particles with education environmentally friendly carbonic acid and molecular nitrogen is considered during the work of a low-temperature swirl fire chamber. Based on the analysis of physical and chemical processes of a fuel chemically connected energy transition into thermal, using the diffusive and kinetic theory of burning modern approaches the technique, mathematical model and the settlement program for assessment of plant ecological indicators when using a new method are developed. Alternative calculations of furnace process are carried out, quantitative assessment of nitrogen oxides emissions level of the reconstructed boiler is executed. The results of modeling and experimental data have approved that the organization of swirl burning increases overall performance of a fire chamber and considerably reduces emissions of nitrogen oxides.

Moving within the city, both by vehicle and foot, is a prerequisite of creating visual sequences. A variety of factors should be taken into consideration when planning cities, not only of functional nature, but of the aesthetic nature as well. A particular problem lies in complex cities, which have a complex spatial matrix of different time layers resulting from development over a long period of time. Given that the city needs to provide the needs of its users, who move through it, one of the most important factors needed is easy orientation in a complex urban space. The research is based on the assumption of easy orientation and movement through the city, as well as on the striking appearance of urban elements that facilitate the memory of the city.. This work deals with defining important factors effecting perceiving and memorizing, by inhabitants and also of those visiting it for the first time, regardless they are walking or using a vehicle. Physical structures, topography and a climate and a range of other elements are important in order to create a clear idea of some urban area. Many elements were considered - not only being of fixed nature (streets, squares, topography and morphology), but also elements that form the essence of the urban image – elements that can also be some specific public transportation means, such as double-deckers in London, bicycles in Amsterdam or Beijing, or gondolas in Venice. The purpose of this work is to point out the rules helping the urban planning process and contribute to reading and memorizing the image of the city.

Unique urban image cannot be experienced without moving within its structure. This paper deals with phenomenology considering changes of images of the city and influential factors closely related to it. Infrastructure gives basic structural scheme of every city, so its planning requires a high level proficiency. Some changes in these images can be observed during longer period of time. Sometimes it includes rapid changes of temporal layers, generated by building new urban elements on the exact same place where the old ones existed; while lighter change during the time passing is a regular occurrence. Creating completely new urban frames, caused by expanding the city, represents its dynamical variant. Topography is a significant factor, giving distinctive feature to the urbanity. This paper considers factors identified as generators of the change of the urban image, based on research so far. The structural elements are considered with the utmost attention. The importance of the city landmark, monumental complexes not possessing these features but having the importance in image of the city stability (as well as the inhabitants' memory) are crucial elements of identifying its picture. Another significant factor is related to individual personal experience. However, there are also certain factors of significance features, but not considered within this paper. One such factor is change in coloring, being the special topic itself. The purpose of this work is to indicate that urban planning requires special attention in order to keep continuous nature of the urban image for the city to preserve its visual identity.

The paper presents results of engineering and economical comparison of waste water biological purification plants of dairy products industry. Three methods of purification are compared: traditional biological purification with the use of secondary clarifiers and afterpurification through granular-bed filters, biomembrane technology and physical-and-chemical treatment together with biomembrane technology for new construction conditions. The improvement of the biological purification technology using nitro-denitrification and membrane un-mixing of sludge mixture is a promising trend in this area. In these calculations, an energy management which is widely applied abroad was used. The descriptions of the three methods are illustrated with structural schemes. Costs of equipment and production areas are taken from manufacturers' data. The research is aimed at an engineering and economical comparison of new constructions of waste water purification of dairy products industry. The experiment demonstrates advantages of biomembrane technology in waste water purification. This technology offers prospects of 122 million rubles cost saving during 25 years of operation when compared with of the technology of preparatory reagent flotation and of 13.7 million rubles cost saving compared to the option of traditional biological purification.

In the article, the information modelling technology (BIM) that is gaining popularity in Russia and in the world, is considered. Its growing relevance relates to many factors: first, attention to this technology by the local and federal authorities; Secondly, with the desire to improve the quality of design documentation, to obtain the correct volumes of materials and equipment; Thirdly, with the tendency to create "smart" cities and, as a result, the rational use of energy resources. Within the framework of this article, on an example of an urban infrastructure object, the pros and cons of this technology were considered. As a facility, a local wastewater treatment plant was chosen. The stages of creating an information model on the available documentation are described: 4 main milestones that need to be implemented. In addition, further possible ways of using the model are described. Presented are the pros and cons of using this technology. Among the main advantages is the possibility of using this information model in the operation of treatment plants and further obtaining actual data for monitoring the condition of equipment and, therefore, controlling the consumable resources; At an early stage, a reduction in the number of mutual intersections of engineering systems; Obtaining the correct specifications. The results of the work described in the article can be used in the following areas: utilities, energy management, design and construction.

In the paper, the stress-strain state of the springs from carbon fiber reinforced plastic was analyzed at its loading by a vertical load. The orthotropy of the material was taken into account. The solution was implemented in the software complexes Lira, ANSYS, and also using the program specially developed by the authors in the Matlab package. In the first case, the part was modeled by three-dimensional finite elements in the form of tetrahedral. In Lira and Matlab we used the plane finite elements of the plates. Comparison of the results obtained in three software complexes is given.

The article describes the main provisions of the theory of fractal geometry, two- and three-dimensional fractals. The possibility of using the fractal theory in the design of buildings and structures, as well as individual elements of the building structures is proposed. The fractal structure has been developed by parametric methods using program «3D modeling of Fractals» with the help of finite element method.

The paper has its focus on the problem of estimating the stress-strain state of the vertical steel tanks with the inadmissible geometric imperfections in the wall shape. In the paper, the authors refer to an actual tank to demonstrate that the use of certain design schemes can lead to the raw errors and, accordingly, to the unreliable results. Obviously, these design schemes cannot be based on when choosing the real repair technologies. For that reason, authors performed the calculations of the tank removed out of service for the repair, basing on the developed finite-element model of the VST-5000 tank with a conical roof. The proposed approach was developed for the analysis of the SSS (stress-strain state) of a tank having geometric imperfections of the wall shape. Based on the work results, the following was proposed: to amend the Annex A methodology "Method for calculating the stress-strain state of the tank wall during repair by lifting the tank and replacing the wall metal structures" by inserting the requirement to compulsory consider the actual stiffness of the VST entire structure and its roof when calculating the structure stress-strain state.

The paper deals with the study of rigidity of a vertical steel cylindrical tank and its structural elements with the development of inhomogeneous subsidence in ANSYS software complex. The limiting case is considered in this paper: a complete absence of a base sector that varies along an arc of a circle. The subsidence zone is modeled by the parameter n. A finite-element model of vertical 20000 m³ steel tank has been created, taking into account all structural elements of tank metal structures, including the support ring, beam frame and roof sheets. Various combinations of vertical steel tank loading are analyzed. For operational loads, the most unfavorable combination is considered. Calculations were performed for the filled and emptied tank. Values of the maximum possible deformations of the outer contour of the bottom are obtained with the development of inhomogeneous base subsidence for the given tank size. The obtained parameters of intrinsic rigidity (deformability) of vertical steel tank can be used in the development of new regulatory and technical documentation for tanks.

Magnesium oxide wallboard is the building and finishing material, which has a reputation of new generational ecological constructing material. It has a wide range of uses: as a revetment in ventilated facades' production, as a decorative material, as different types of formworks for a foundation filling and as a protector against a fire threat. During the study it was considered that magnesium oxide wallboards have some defects, such as moisture formation as a concentrated brine on the surface under special climatic conditions and absence of clear distinguishing between different types of magnesia boards. Usage of this material can become a cause of frame's corrosion and origin of mold on wooden details. Authors provide the information from a foreign data source about negative consequences of SML usage. In conclusion researchers state that it is necessary to provide a clear magnesium wallboards classification and define technical requirements, which will, in their opinion, lead to Russian standard formulation.

The article discusses the problem of targeted control over properties by modifying the supramolecular structure of polymer binders and composites based on their hierarchy. Control over the structure formation of polymers and introduction of modifying additives should be tailored to the specific hierarchical structural levels. Characteristics of polymer materials are associated with structural defects, which also display a hierarchical pattern. Classification of structural defects in polymers is presented. The primary structural level (nano level) of supramolecular formations is of great importance to the reinforcement and regulation of strength characteristics.

A mathematical model of the hysteresis of the water-retention capacity of the soil is proposed. The parameters of the model are interpreted within the framework of physical concepts of the structure and capillary properties of soil pores. On the basis of the model, a computer program with an interface that allows for dialogue with the user is developed. The program has some of options: visualization of experimental data; identification of the model parameters with use of measured data by means of an optimizing algorithm; graphical presentation of the hysteresis loop with application of the assigned parameters. Using the program, computational experiments were carried out, which consisted in verifying the identifiability of the model parameters from data on the main branches, and also in testing the ability to predict the scanning branches of the hysteresis loop. For the experiments, literature data on two sandy soils were used. The absence of an "artificial pump effect" is proved. A sufficiently high accuracy of the prediction of the scanning branches of the hysteresis loop has been achieved in comparison with the three models of the precursors. The practical importance of the proposed model and computer program, which is developed on its basis, is to ensure the calculation of precision irrigation rates. The application of such rates in irrigation farming will help to prevent excess moisture from flowing beyond the root layer of the soil and, thus, minimize the unproductive loss of irrigation water and agrochemicals, as well as reduce the risk of groundwater contamination and natural water eutrophication.

The article presents the results of experiment-calculated determination of the effective area of the system of thermal stabilization of soil under the oil settler in the zone of permafrost soil. The comparison of the value of the surface area of the cooling tubes calculated with the help of the proposed equation with the surface area of the coil used in the experiment showed the possibility of using the proposed method for calculating the horizontal systems of thermal stabilization of soils under the buildings in the experimental conditions.

The problems of cleaning low turbidity high-color surface waters for drinking water supply are considered. A new design of the clarifier reactor is proposed, which increases the efficiency of water purification and at the same time reduces its operating costs. A detailed description of clarifier reactor design and its operation is given. The study results of the clarifier reactor operation in real conditions for the purification of low turbidity high-color waters are shown. Due to the weighted layer of dense loading use in a process of water purification, the structure productivity can be increased by 2-3 times in comparison with conventional clarifiers with suspended sediment. Using reagents for water purification, the clarifier reactor, due to the processes of contact coagulation, allows reducing the consumption of reagents up to 50%. Investigations of the clarifier reactor operation in technological schemes for various waters purification, including sewage, showed their effectiveness and prospects.

The problem of flood protection measures are considered in the paper. The regulation of river flow by the system of Self-Regulated Flood Dams (SRFD) is analyzed. The method of SRFD modeling in GIS environment is proposed. The question of the ecological aspect of the SRFD management is considered based on the hydrophysical properties of the soil. The improved Mualem-Van Genuchted method is proposed for the evaluation of the possible SRFD location influence on the soil of flooded territory – the temporary reservoirs. The importance and utility of the proposed complex method is stated.

The article considers the methodological and practical aspects of reclamation of landfills and dumps of municipal solid waste in a waste management system. The general tendencies of system development in the context of elements of the international concept of waste hierarchy are analyzed. Statistics of the formation and burial of domestic waste indicate a strategic non-alternative to the rejection of landfill technologies in favor of environmentally, energy efficient and economically expedient ways of utilization of municipal waste as a world trend. Practical approaches to the study of territories on which there are dumps and landfills are considered to justify the design solutions for reclamation.

Correctly designed transport infrastructure should support the current economic relations. It should provide a reserve for development of economy of the region in the future. In Western Siberia, new highways are actively being built and major repairs of the operating roads are being conducted. Local materials are often used in the roadbed construction. In the Tyumen region, it is usually sandy silt and clayey sand. The soil has unfavourable physico-mechanical properties. The soil is prone to water and wind erosion. This type of ground gets on the adjacent to the road territory. Studies on the influence of highways on soil permeability were carried out on the basis of the federal highway Tyumen-Omsk. Three types of soils, which are actively used in the agricultural sector, were considered. It is found that the content of particles with the size less than 0.01 mm reaches 32% in the soil used in road construction. It is noted that a part of these particles accumulates on the adjacent to the road territory since it is being washed out from roadbed. The content of physical clay (<0.01 mm) in soils increases by 34-62% relative to the initial values. The width of active accumulation of silt particles reaches 15-20 m along the roads. The soils at the distance up to 10 m from the highway are almost impermeable to water. Absence of a natural hydrological drain, results in the territory bogging. An inverse close correlation was established between the content of physical clay (<0.01 mm) and water permeability (r = 0.90).

Technological solutions for the transportation may be different in Russia, the developed network of Railways, efficiently functioning system of inter-regional pipelines, experiencing a rebirth water transport, however, a special place is occupied by road transportation.

Problems of environmental friendliness and energy efficiency in recent decades have become not only the most important issues of economic development of the main industrial economies, but also the basis for the processes of maintaining the security and relative stability of the global ecosystem. The article presents the results of the study of the status and trends of the development of environmental standards for the construction and maintenance of real estate in the world and particularly in Russia. Special market instruments for assessing the compliance with the quality of real estate projects under construction and modern principles of environmental friendliness and energy efficiency include voluntary building certification systems that are actively used in international practice. In Russia there is active use of the following international systems of certification: BREEAM, LEED, DGNB, HQE. Also in the Russian certification market, the national standard STO NOSTROY 2.35.4-2011 "Residential and public buildings" is being implemented, which summarizes the best international experience of the rating evaluation procedure. Comparative characteristics of the "green" standards and the principles of rating assessments of the ecological compatibility of buildings give an idea of applying these standards in Russia.

In the article the ways of protection of barrier road constructions from various external influences which cause development of irreversible corrosion processes are considered. The author studied modern methods of action on metal for corrosion protection and chose the most effective of them: a method of directly affecting the metal structures themselves. This method was studied in more detail in the framework of the experiment. As a result, the article describes the experiment of using a three-layer polymer coating, which includes a thermally activated primer, an elastomeric thermoplastic layer with a spatial structure, and a strong outer polyolefin layer.

Stabilization of marlous soils with Portland cement will increase the service life of motor roads in areas where marl is used as a local road construction material. The result of the conducted research is the conclusion about the principal possibility of stabilization of marlous soils with Portland cement, and about the optimal percentage of the mineral part and the binding agent. When planning the experiment, a simplex-lattice plan was implemented, which makes it possible to obtain a mathematical model for changing the properties of a material in the form of polynomials of incomplete third order. Brands were determined for compressive strength according to GOST 23558-94 and variants of stabilized soils were proposed for road construction.

Working capacity of traffic facilities in the northern European part of Russia depends on difficult natural climatic conditions. It means deep frost penetration and high ground-water level. Both two factors considerably impact on the amount of frost boil of soils in the roadbed. Because of the analysis of a water-and-thermal regime of soil it is possible to detect it's characteristic, to adjust initial and boundary conditions in the performance of theoretical tasks based on laws of thermodynamics for description of migration process of heat and damp in the road bed. A solution was found with a numerical inversion of Laplace transformation. Realization of that task makes possible to forecast dampness to the end of winter period and to determine the amount of frost boil of soils. To avoid subgrade deterioration in this period the temporary axle load limitations on public roads are imposed.

Use of Insulated Glass Units (IGU) as glazing on building façades causes optical distortions of mirrored images of neighboring buildings in glazed surfaces. Optical distortions are caused by varying distances between glass panes in IGUs as a result of climate factors. This paper examines available engineering solutions that reduce such distortions: use of more rigid outer glasses, encasing the building in a shell of single glass panes, known as the 'double façade', and use of vacuum IGUs. A new way is proposed to reduce optical distortions by installing additional pointed or linear supports and creating pre-stress with partial rarefaction inside the IGU. Overpressure that can cause IGU expansion and glass deformation was calculated. In the urban environment of Moscow, reduction of air pressure with simultaneous increase of air pressure inside the IGU during summer heat waves can be as high as 5%, and this figure determines the level of rarefaction.

It is indicated that according to the results of the All-Russian Census of 2010, the total population of the Russian Federation at the time of the survey was 142 million 857 thousand people living in more than 1100 settlements that have the status of the city (subject to their identification by population, administrative and national economic significance and the nature of the building), as well as in almost 160,000 rural settlements. It should be noted that in accordance with the classification of settlements in the Russian Federation, there are five main categories, namely: The above classification of settlements has formed the basis for the analysis of the existing processes of functioning of the heat supply systems of the Russian Federation at the objects of housing, social and industrial development from the point of view of energy security. Thus, for example, it turned out that in large cities with multi-storey buildings the centralized heat supply system is dominated by a system consisting of one or several sources of heat, heat networks having different diameter of pipelines, their number and length, and also serving various types of heat consumers) from cogeneration plants (CHP) of public use, or industrial enterprises.

As for the welterweight and small towns, including urban-type settlements with a multi-storey building of the post-war period, they, as a rule, have the majority of IGFs, fed from the city or district boiler houses.

Based on the analysis of the experimental data the article reveals that if in the area under study a travel length is more than 7 km (about 20 minutes of movement), it becomes possible to obtain stable relationships between the specific parameters of traffic in the network. A further increase in the duration of observations does not cause a change in the trip parameters and the value of the correlation ratio for the model. The corresponding results are achieved with a constant cruising of five "floating" cars in the area under study. Moreover, it is proved that reliable results of estimating the traffic parameters on the network are obtained both for fixed traffic routes of "floating" cars and for randomly choosing routes.

Manufacture of ceramic materials and products largely depends on the preparation of clay raw materials. The main process here is the process of mixing, which in industrial production is mostly done in cross-compound clay mixers of continuous operation with steam humidification. The authors identified features of dynamics of this technological stage, which in itself is a non-linear control object with distributed parameters. When solving practical tasks for automation of a certain class of ceramic materials production it is important to make parametric identification of moving clay. In this paper the task is solved with the use of computational models, approximated to a particular section of a clay mixer along its length. The research introduces a methodology of computational experiments as applied to the designed computational model. Parametric identification of dynamic links was carried out according to transient characteristics. The experiments showed that the control object in question is to a great extent a non-stationary one. The obtained results are problematically oriented on synthesizing a multidimensional automatic control system for preparation of ceramic mixture with specified values of humidity and temperature exposed to the technological process of major disturbances.

The article presents the results of experimental research of the influence of organosilicone compounds on porosity parameters, contact angle of fiber cement panels based on cellulosic fiber in superficial expansion and volumetric methods of hydrophobization.

Authors completed the analysis of the accepted practice of classification of the sawn car bodies in Russia. They conclude that the tools of the Product Range of Foreign Economic Activity do not allow to classify the front and rear parts of the car as goods. Nowadays the participants of foreign economic activity sent the efforts to search for any new way to cut the customs payments. Meanwhile that is not incidental, that during car sale, the sellers specify in their offers not only purely technical characteristics but also the fact that "It is not a Sawn Car". Thereby the sellers of cars agree that the car, obtained by joint of the sawn parts in the handicraft conditions, have an uncertainty of such important characteristic as safety, and that reduces the consumer properties of the purchase. Many buyers consider unsafe and even impossible to use the car in which such fundamental characteristic as safety is not provided. Therefore, the attempts of customs to carry out any classification of goods in the commodity position 8703 for the increase in collectable customs payments have a negative side as the matters of health and life of future owner of the car are concerned.

Sustainable development of trailering in Russia needs energy efficient and environmentally safe localization of the providing infrastructure which includes customer services, such as enterprises of hospitality (campings). Their rational placement minimizes the fuel consumption by vehicles, but also emissions of harmful substances into the atmosphere. The article presents rational localization of the sites for the construction of such enterprises using the MATLAB program. The program provides several levels of the task solution: from the total characteristic of the territory (the head interface) to the analysis of the possibility of forwarding charges on visit of the enterprises of car service (petrol station, automobile spare parts shops, car repair enterprises, cafe, campings and so on). The program offered implementation of the optimization by the criterion of decrease in energy costs allows to establish the preferable fields of their rational localization.

The most effective building materials account for the highest growth not only in construction of residential and public buildings, but also other capital projects including roadways, bridges, drainage, communications and other engineering projects. Advancement in the technology of more efficient and ecologically responsible insulation materials have been a priority for safety, minimal maintenance and longevity of finished construction projects. The practical use of modern building materials such as insulation, sound reduction and low energy consumption are a benefit in cost and application compared to the use of outdated heavier and labor-intensive materials. The most efficient way for maximizing insolation and sound proofing should be done during the design stages of the project according to existing codes and regulations that are required by Western Government. All methods and materials that are used need to be optimized in order to reach a high durability and low operational and maintenance cost exceeding more than 50 years of the life of the building, whether it is for public, industrial or residential use. Western construction techniques and technologies need to be applied and adapted by the Russian Federation to insure the most productive successful methods are being implemented. The issues of efficient insulation materials are outlined in this article.

The article contains actual data on the review of the performance of the transport infrastructure in Russia. The problems and restrictions, affecting its sustainable development, are identified; their interaction and interrelations are traced. The authors argue that the majority of the revealed restrictions are of internal character and mainly is the feature of the state contract scheme. According to the authors, the scheme of public-and-private partnership is an effective mechanism, which can be suggested for the existing problems solution.

The paper is aimed to figure out the cost of modernization of the transport infrastructure of the Northern Sea Route. Main unfavorable factors, such as fall in prices for energy resources and the necessity of the implementation of ecologically safe and energy efficient technologies are taken into account.

The article analyzes the problems of outdoor stationary sun-protective devices (S.P.D.) and their influence on the natural daylighting levels in the premises of civil objects of transport infrastructure under the hot and sunny climatic conditions of the environment. It is noted, that with clear sky, typical for the said climate, non-uniform luminance of the sky differs seriously from the luminance of standard overcast sky with diffused light, recommended by C.I.E. (Commission International D'Eclairage).A conclusion is made, that with clear sky conditions, a sun-protective devices in the form of stationary canopies (awninas) help to improve the lighting environment in the premises considered. This becomes possible due to reflected sun flow from the surfaces of SPD employed, as well as due to rise of a daylight factor values in farmost from windows zones of interiors, because of the increase of luminance factor values of the sky areas, observed from these zones. Thus, the SPD considered, in the hot and sunny climatic conditions are able not only to carry out their main function of passive method of solar radiation and thermal control in the interiors, but also to act as an efficient measure to improve lightning environment of the premises in question.

Surge phenomenon occurs on the pipeline by the closing valve or pump suddenly lost power. Due to the complexity of the water hammer simulation, previous researches have only considered water hammer on the single pipe or calculation of some positions on water pipe network, it have not been analysis for all of pipe on the water distribution systems. Simulation of water hammer due to closing valve on water distribution system and the influence level of pressure surge is evaluated at the defects on pipe. Water hammer on water supply pipe network are simulated by Water HAMMER software academic version and the capacity of defects are calculated by SINTAP. SINTAP developed from Brite-Euram projects in Brussels-Belgium with the aim to develop a process for assessing the integrity of the structure for the European industry. Based on the principle of mechanical fault, indicating the size of defects in materials affect the load capacity of the product in the course of work, the process has proposed setting up the diagram to fatigue assessment defect (FAD). The methods are applied for water pipe networks of Lien Chieu district, Da Nang city, Viet Nam, the results show the affected area of wave pressure by closing the valve and thereby assess the greatest pressure surge effect to corroded pipe. The SINTAP standard and finite element mesh analysis at the defect during the occurrence of pressure surge which will accurately assess the bearing capacity of the old pipes. This is one of the bases to predict the leakage locations on the water distribution systems. Amount of water hammer when identified on the water supply networks are decreasing due to local losses at the nodes as well as the friction with pipe wall, so this paper adequately simulate water hammer phenomena applying for actual water distribution systems. The research verified that pipe wall with defect is damaged under the pressure surge value.
