Introduction. Engineering solutions of construction facilities are becoming obsolete due to the impact of scientific and technological progress, changes in consumer needs and production capabilities of the construction industry. A gap between consumer needs and characteristics of construction products is bridged by updating, modernizing, retrofitting and transforming design solutions. Materials and methods. The subject of the study is capital construction facilities that have various functional purposes: they structure built-up urban areas (space planning), whose urban planning solutions need reengineering in the course of operation. The article considers the list of capital construction entities that include industrial facilities (manufacturing, agricultural, and communication facilities), non-industrial facilities (public buildings, residential housing) and linear objects (overpasses, pipelines, power grids). Functional, planning, structural, organizational and technological features of capital construction facilities, features of vital processes, production and technological procedures, that are underway inside them, determine the characteristic differences in the composition and structure of construction reengineering. Structural and functional analysis is the research method of the study. Results. The composition of actions and methods used to reengineer residential and industrial buildings, areas occupied by the engineering and transport infrastructure is described. The article presents changes introduced by reengineering actions with regard for the features of facilities that structure urban development. The co-authors acknowledge that the structure and composition of construction reengineering are highly variable, and their variability is determined by the types of built-up areas and their transformation methods. This dependence impacts a combination of reengineering actions, including those that determine the nature of transformation and supplement the principal change. The research results allow to develop reengineering process organization charts and outline the resource provision process.

The article deals with the issues related to the assessment of the technical condition of structural elements, taking into account the stages of engineering research, design and installation. The importance of the topic under consideration is due to a large number of accidents at civil and industrial facilities that occur before the exhaustion of the bearing capacity. The analysis of the object (the metal frame of industrial buildings) is carried out on the basis of project documentation, data obtained by a full-scale survey, visual and instrumental control, numerical methods of research. The qualitative and quantitative parameters of the capital construction object necessary for assessing the technical condition are presented. They include design schemes of frame structures, materials, their characteristics, defects and parameters. The study shows the importance of comprehensive assessment of capital construction facilities in terms of constructive safety. Identification of errors at each stage of construction allows to prevent emergencies that lead to the destruction of the load-bearing system and to develop measures to establish the possibility (impossibility) of repair or reconstruction

The impacts of manmade structures on wildlife are often underestimated due to misbelieve that wild animals avoid living in close proximity to any kind of technogenic object. However, such objects may offer a range of benefits to animals and thus become points of attraction, being still a source of hazards for these living organisms. The airports are considered to be dangerous industrial facilities for they create chemical and physical pollution, as well as host a variety of biohazards, originating from transported items and dense groups of population. Meanwhile they are often located outside the urban areas in previously pristine areas, specially allocated for this purpose and animals, whose habitat they occupy undergo all these impacts equally with passengers and staff. The aim of the research is to conduct differential analysis of physical factors of influence within the airport impact area and evaluate the negative trends for exposed animals. The physical factors were divided into the physical objects and physical fields. The assessment of these factors was based on the data obtained using special metering equipment for measuring the level of noise, light and electro-magnetic pollution, while the intensity of visual pollution and fragmentation effects by airport infrastructure were evaluated using qualitative approach. The airport facilities itself and ground access infrastructure are showed as the causes of habitat destruction by barrier and edge effects, as well as structural transformations of landscapes, in particular, relief and phytocenosis. The impact of physical fields coming from the airport territory is formed by light, vibration and electro-magnetic pollution. The intensity of considered factors is different, but the sensitivity of laboratory animals to these factors is high enough to cause a range of effects. However, the methods for mitigation of some other airport impacts can exacerbate the value of the existing sources of impacts. The light pollution is measured and defined as the most significant and damaging. Thus, there is a clear need to pay attention to the interactions between an airport and wildlife to reduce the intensity of negative effects. The predicted and described effects for wildlife could be very diverse, but they need verification by field surveys in the impacts areas of airports is highlighted.

This article deals with the problems of failures of transport infrastructure sections and their consequences. The article presents the research problem of assessing the impact of the fire on Lazienkowski Bridge, in Warsaw, on the travel behaviour of city residents as well as traffic conditions in the city. Changes occurring directly after the bridge’s failure during the period up to several months after the event were analysed. In order to assess the consequences of the failure, data obtained from traffic measurements on selected bridge crossings and interview surveys carried out among city residents were used. The results of the surveys proved that the exclusion of the Lazienkowski Bridge from traffic resulted in a significant increase in traffic volumes on other bridges, especially neighbouring ones, and resulted in longer rush hours on the bridge crossings in question. 42% of the city‘s residents felt the negative consequences of the failure in the form of worse conditions of travel and 36% of the residents reported a longer travel time to work/school. The failure also caused changes in travel behaviour as regards the choice of means of transport, travel route or not travelling altogether. The consequences of the failure affected, to the greatest extent, the residents of areas most functionally connected with the bridge.

In the last few years, a negative impact on the environmental values of the Lithuanian urban landscape was made by an increasingly growing urbanization: more densely situated buildings, growing areas of solid concrete or other surface, less and less space for greenery. Soon, roofs shall be equipped not only with antennas, but also with solar collectors and small wind turbines. All this will undoubtedly have an impact on the architectural expression of buildings and landscapes and in the near future, the impact will become even more significant. To achieve high aesthetic value and ecological stability of Lithuanian urban landscapes, the necessary number of studies are required as well as regulatory planning and legislative measures to guarantee the high quality of landscapes not only in the coming years, but in the long term as well. Dust and gas polluted air creates major threat to human health in urban areas. Atmospheric air saturated with harmful substances penetrates into residential housing, hospitals, educational institutions and classrooms, and industrial premises. Indoor air is saturated with chemicals and substances, such as xylene, benzene, formaldehyde, ammonia, acetone and others, are released by building materials and furniture. Besides, there is also human and bio-depleted air. Free planting of trees and shrubs, flowers, grass, balcony attached trays, and plants in pots at the premises is no longer sufficient in urban areas.. Drastic architectural and urbanistic measures are required to help people in the city to restore the natural environment. We are children of nature and we have to move closer to it. To hide urban monotony, considerable efforts have to be made: plans – our friends – should take their places on building roofs and walls, balconies and terraces. This article analyses some of sustainable development issues particular to a Lithuanian city and associated with new technologies pertaining to urban landscape, urban spaces and architectural buildings, architecture, and environment. Some preliminary proposals for possible solutions to improve the basic architecture of buildings and townscapes to enrich the life of new high-quality brands are offered. Santrauka Pastaruoju laikotarpiu Lietuvos miestų kraštovaizdyje vis labiau daugėja urbanizacijos ženklų, darančių negatyvų poveikį aplinkos estetinėms vertybėms ir gyvenimo kokybei. Tankėja užstatymas, vis mažiau vietos lieka želdiniams, didėja kietų betoninių ar kt. paviršių plotas. Ant pastatų stogų įrengiami pavieniai saulės kolektoriai, antenos, mažosios vėjo jėgainės ir kt. Augalai išstumiami iš renovuojamų daugiabučių pastatų kiemų prioritetą suteikiant automobiliams. Nebelieka vietos vaikų žaidimų aikštelėms. Pastatų viduje oro kokybė ne geresnė kaip kieme ar gatvėje. Visa tai neabejotinai daro įtaką architektūrinei pastatų bei miestovaizdžių raiškai bei žmonių sveikatai. Ateityje, tankėjant užstatymui miesto centrinėse dalyse, ta įtaka dar labiau didės. Dulkėmis ir dujomis užterštas oras kelia didžiulę grėsmę žmonių sveikatai. Atmosferos oras, prisotintas kenksmingų medžiagų, skverbiasi į gyvenamuosius būstus, ligonių palatas, mokymo įstaigų klases ir auditorijas, gamybines patalpas. Jau nebepakanka laisvus plotus miestuose apsodinti medžiais ir krūmais, gėlėmis, apsėti žole. Būtinos kardinalios priemonės, padedančios žmogui mieste sugrąžinti natūralią gamtinę aplinką. Siekiant aukštos Lietuvos miestų kraštovaizdžių estetinės vertės, ekologinio stabilumo, būtini sisteminiai architektūriniai ir urbanistiniai tyrimai, taip pat pastatų ir kvartalų, pastatų aplinkos projektavimą reglamentuojančios, planavimo bei teisinės priemonės, kurios garantuotų aukštą kraštovaizdžio kokybę ne tik artimiausiais metais bet ir perspektyvoje. Šiame straipsnyje analizuojami kai kurie Lietuvos miestų darnaus vystymosi aspektai susieti su naujų kraštovaizdžio technologijų įtaka urbanizuotų miesto erdvių aplinkai, pateikiami preliminarūs siūlymai, kaip naujus aplinkos elementus kuo tinkamiau išnaudoti gerinant pastatų architektūrą, miesto vaizdą, gyvenimo kokybę.

The stage of construction is one of the main compulsory periods of the life cycle in the formation of construction end-products – capital construction projects of various functional purposes. The compulsory assessment of conformity of buildings and structures, as well as design construction, installation, setting up and recycling (demolition) processes associated with buildings and structures is conducted in Russia in the form of state construction supervision. An assessment results in a document certifying conformity of the actual indicators with the requirements of design, normative (industrial) and legislative documents. Conformity is assessed in accordance with procedural rules depending on the functional purpose of the capital construction project. There are two conformity assessment forms that appear to be similar: “construction inspection” and “state construction supervision”. They both characterize an approach used to assess the conformity of activities of participants in the construction operations (customers, developers, contractors) on formation of construction end-products – capital construction projects. These terms differ in so far as the construction inspection implies control by the customer of operations of contractors. State construction supervision authorities undertake supervisory (including inspection) activities in order to identify and crack down on violations of the requirements of technological regulations or other normative legal acts and design documents, committed by the key players in the construction investment activities (customer, developer, contractors), with the involvement of state authorities.

currently, there is an urgent issue of developing recommendations in the field of reconstruction and redevel-opment of industrial zones against the background of the lack of federal and regional programs for the re-profiling of industrial territories in Russia that regulate the procedure for working with industrial zones. The irrational use of land resources of cities, in which large areas are still occupied by industrial facilities, raises a number of problems of an economic and social nature: a high level of environmental pollution, and as a result, an increase in the incidence of the population, overloading of transport infrastructure, and a lower level of budget system income from harnessing the potential of urban land. In addition, a situation often arises when some of industrial enterprises fall into decay or completely cease their activities. And as a result, such of industrial areas degrade and are not exploited. Another important factor in this problem is the architectural appearance of the old industrial territories in the modern cities. During the industrial period of the formation of urban plans, the situation arose when in many cities such industrial areas are located in the central part of the cities and affect the architectural appearance of the urban environment. The article analyzes and discusses solutions to achieve a result when the industrial territories in the cities, after their reconstruction and reprofiling, in addition to new functional significance, become attractive centers with developed infrastructure

Transport accessibility is assumed to be a main driver of urbanisation. Like many other metropolitan regions, the Randstad, the population and economic core of the Netherlands has experienced significant urbanisation, transport network expansion and spatial policies aimed to channel urban growth. This paper investigates the long-term relationships between the development of railway and motorway networks, urbanisation, and spatial policies, by using a panel dataset consisting of grid cells measured at six time points from 1960 to 2010. Generalised Estimating Equations analysis was applied to model the built-up area. Predictors include proximity to and accessibility by transport infrastructure, vicinity of urban areas, and spatial policies. Results indicate that road and rail accessibility alike, stably influenced urbanisation, but less than proximity to urban areas. Spatial policies played a significant role in channelling new urbanisation, while preserving the centrally located green and mainly rural area. Remarkably, the legacy of earlier policies is still significant despite shifts in predominant Dutch spatial policies. The findings are expected to be relevant for comparable poly-nuclear areas.

Recently, the number of published works devoted to the processes of synanthropization of fauna, is growing like an avalanche, which indicates the extreme urgency of this theme. In our view, the process of forming devices to coexist with human and the results of his life reflects the general tandency of the modern nature evolution. Urbanization is characteristic for such a specific group of animals like amphibians, the evidence of which are numerous literature data. Many researchers use this group to assess the bioindicative quality of the environment. For this aim a variety of indicators are used: from the cellular level of life of organization up to the species composition of the group in different territories. At the same time, the interpretation of the results is not always comparable for different areas and often have significantly different interpretations by experts. Urban environment, primarily due to the contamination is extremely aggressive to amphibians. As a consequence, the urban populations of amphibians may be a change in the demographic structure, affecting the reproductive ability of the population, the disappearance of the most sensitive species or individuals, resizing animals, the appearance of abnormalities in the development, etc. At the same time play an important amphibians in the ecosystems of cities, and some species in these conditions even feel relatively comfortable. Therefore, it is interesting to understand the mechanisms of self-sustaining populations of amphibians in urban environments. To assess the impact of natural and anthropogenic factors on the development of amphibian populations were used cognitive modeling using the program Vensim PLE. Cognitive map of the model for urban and suburban habitat conditions were the same. The differences concerned the strength of connections between individual factors (migration, fertility, pollution) and their orientation. In general, factors like pollution, parasites, predators had negative impact on the population, reducing its number. The birth rate, food and migration contributed to raising number of individuals. Some of the factors affected on the strength to of each other as well: the majority of the factors affected the structure of the population, had an influence on the fertility. Thanks to it the model reflects the additive effect of complex of factors on the subsequent status of the population. Proposed and analyzed four scenarios differing strength and duration of exposure. In the first scenario, a one-time contamination occurs and not subsequently repeated. The second and third scenario assumes half board contamination, 1 year (2 scenario) and two years (scenario 3). In the fourth scenario, the pollution affected the population of amphibians constantly. In accordance with the results of simulation, much weaker than the natural populations respond to pollution - have them as an intensive population growth and its disappearance at constant pollution is slow. Changes to other parameters of the model showed that this pollution is the decisive factor -only the constant action leads to a lethal outcome for the populations. All other components of the model have a corrective effect on the population dynamics, without changing its underlying trand. In urban areas due to the heavy impact of pollution maintaining the population is only possible thanks to the migration process – the constant replenishment of diminishing micropopulations of natural reserves. This confirms the assumption that the form of existence metapopulations lake frog in the city. In order to maintain the number of amphibians in urban areas at a high level it is necessary to maintain existing migration routes and the creation of new ones. Insular nature of the placement of suitable habitats in urban areas causes the metapopulation structure of the types of urbanists. Therefore, the process of urbanization is much easier for those species whicht are capable of migration in conditions of city. In the initial stages of settling the city micropopulationis formed by selective mortality of the most susceptible individuals to adverse effects. In future, maintaining the categories of individuals is provided mainly due to migration processes metapopulisation form of the species of existence is supported). It should be noted that the changes in the previous levels are always saved in future. In the case of reorganizations of individuals we of morphology can assume the existence of extremely adverse environmental conditions that threaten the extinction of the micropopulations.

Subject. The paper considers national projects in the field of transport infrastructure, i.e. Safe and High-quality Roads and Comprehensive Plan for Modernization and Expansion of Trunk Infrastructure, and the specifics of their implementation in the Rostov Oblast. Objectives. The aim is to conduct a statistical assessment of the impact of transport infrastructure on the region’s economic performance and define prospects for and risks of the implementation of national infrastructure projects in conditions of a shrinking economy. Methods. I use available statistics and apply methods and approaches with time-series data, namely stationarity and cointegration tests, vector autoregression models. Results. The level of economic development has an impact on transport infrastructure in the short run. However, the mutual influence has not been statistically confirmed. The paper revealed that investments in the sphere of transport reduce risk of accidents on the roads of the Rostov Oblast. Improving the quality of roads with high traffic flow by reducing investments in the maintenance of subsidiary roads enables to decrease accident rate on the whole. Conclusions. In conditions of economy shrinking caused by the complex epidemiological situation and measures aimed at minimizing the spread of coronavirus, it is crucial to create a solid foundation for further economic recovery. At the government level, it is decided to continue implementing national projects as significant tools for recovery growth.
