Assessment of the residual resource of several buildings and structures as a unified object

In this article, the authors raises the problem of assessing the residual resource of an object consisting of several buildings and structures. Four different approaches to solving this problem are presented. The advantages and disadvantages of them are considered, and the application areas of these approaches are indicated. Within the framework of these approaches, one can use the direct enumeration method, the combinatorial method, the algebra of logic, and the general logical-probabilistic method. The authors has developed two possible options for calculating the residual resource of these objects using the general logical-probabilistic method. It is proposed to develop a methodology for calculating the residual life of such objects before conducting a survey. The authors indicates the main points that must be included in the developed methodology.

Experience in the application of surface foundations for a frame building in the vicinity of St. Petersburg

The article presents the experience of constructing buildings on surface foundations in winter season. Within the frames of the investigation, there were evaluated temperatures in the base composed of heaving soils, as well as foundation displacements during the winter period. There have been were performed calculations of temperature fields and soil heaving deformation using the Termoground program. It is shown that despite the relatively big depth of the base soil freezing, the maximum displacements of the foundations did not exceed 7 mm, which is quite acceptable for a frame building.

Problems of functioning and prospectsfor the development of certification in construction

The article presents an overview of the state of the market of mandatory and voluntary certification in construction on the territory of the Russian Federation. The key unresolved problems of the existing conformity assessment systems are identified. Based on the analysis carried out, there are proposed some mechanisms and ways of solving these problems, which would help restoring trust in voluntary certification systems among both active market participants and ordinary consumers of certification objects.

Creativity of A. L. Benois. Traditions of the St. Petersburg architectural school in the Turkestan region

The article provides a brief summary of the historical situation of the mid XIX century, when the conquest policy of the Russian Empire predetermined the urban development of the territories annexed in the hostilities, the spreading of the St. Petersburg architectural school traditions in them. The propagators of its creative principles were the graduates of the Institute of Civil Engineers, the Construction School of the Main Directorate of Railways and Public Buildings, the Academy of Arts.The main attention in the article is paid to the creative activity of the architect Alexei Leontievich Benois, whose heritage was a reflection of the traditions of the St. Petersburg architectural school of the mid-XIX in Turkestan. The stylistic affiliation of his buildings is analyzed, the creative method is determined.The information provided in the article about the heritage of A. L. Benois, complemented the overall picture of the domestic architecture development as an integral artistic system within the vast borders of the Russian Empire.

Benchmarking as a tool for managing organizational innovations at investment and construction enterprises

This article defines the concept and importance of introducing organizational innovations for companies and substantiates the need to manage them. Organizational innovations ensure the survival of the organization on the market, they facilitate the longevity and success of the organization. The authors propose and argue the thesis: «Benchmarking is a tool for managing organizational innovations». It is through the exchange of experience and the study of methods of managerial activities, including the ones in the field of organizational innovations, that it is possible for a company to build an effective strategy of activity and achieve competitiveness.

Analysis of the applicability of the method for assessing the predicted maximum settlement of the surrounding building development in the engineering and geological conditions of St. Petersburg

The article considers the methods for calculating the predicted maximum settlement of buildings in the zone of influence of a deep pit in the conditions of St. Petersburg. There have been analyzed the results of calculations of the predicted maximum settlement by the semi-empirical method developed by Professor N. S. Nikiforova with the settlement values obtained in Plaxis 2D software package. The authors present the evaluation of the possibility of applying a semi-empirical method for determining the predicted settlement of the surrounding building development in the engineering and geological conditions of St. Petersburg.

Digital diagnostics of assessing social risk with killed at single-level road intersections in Russia

The performers of the federal project «Road Safety» and the national project «Safe and High-Quality Highways» are offered an effective, digital technology necessary to achieve the targets of «social risk» with numbers of killed as a result of road accidents by 2024 per 100 thousand people, on the example of St. Petersburg. This technology uses a tool for diagnostic assessment of road safety at single-level road intersections with a mechanism for visualizing the causes of conflict situations in the wayside crosses of traffic and pedestrian flows that cause accidents.

1736-1740-s: new vector of St. Petersburg development

The article considers the functional zoning of the territory of the Admiralteisky Island in St. Petersburg, which had been formed by the beginning of the 1730-s. The evolution of the living environment of sailors and shipyard workers, which was located on both banks of the Moyka River in St. Petersburg, is considered, and the indicators of the urban development compaction taking place during the indicated period are highlighted. The circumstances of the alteration of the urbanization process strategy, which manifested itself in the second half of the 1730-s, are considered. The author emphasizes the fundamental difference between the concept of the times of Peter the Great and the new trend, when artistic and emotional criteria acquired a decisive importance. There are revealed social and economic foundations of forming the system of urban morphotypes. This system has become a tool for the reconstruction of the existing residential area and a means of rational development of new space. The land use system (regulation of the size of parcels) and the alteration in the transport and planning frame (changing of the street route) are proposed to be considered the key tools for the large-scale de-compaction of inhabited districts. The high rates of urban planning transformations of this time and their radical nature are emphasized. A cluster approach to the use of territorial resources and the formation of buildings on the outskirts of the city (late 1730-s - early 1740-s) is noted. A similarity with the modern practice of locating isolated residential complexes in remote areas is shown. It is recommended to take into account the experience of integrating clusters into the urban environment that started to be practiced in the second half of the XVIII century.

Application of coevolutionary genetic algorithms in the problems of determining the place of contact of investigated objects in the examination of road traffic accident

This article considers the method of applying coevolutionary genetic algorithms when performing an expert study to determine the place of vehicles` collision or the place of a vehicle`s collision with a pedestrian in the reconstruction of a road accident. The results of calculation by the proposed method and calculation by the generally accepted method are compared.

Methodology for assessing availability and user demand for public urban passenger transport stops when developing transport planning documents

The paper describes a method of visual assessment of the availability of public passenger transport stops in accordance with SP (construction norms) 42.13330.2016. A method for mathematical modeling of user demand for public passenger transport stops using the Voronoi diagram is proposed and described.
