 35-42 p.
Abstract
It is proposed to use fuzzy production rules when making decisions on inclusion in the title list of public buildings, since in the practice of assessing the technical condition of a building on the basis of an expert opinion based on the results of a survey, the duration of operation determined in accordance with regulatory values, deadlines for work and other indicators affecting the integral potential of including a building in the capital repair and reconstruction plan, such fuzzy concepts as "satisfactory", "unsatisfactory" and others appear. The article proposes the use of the original fuzzy inference methodica to assess the need for major repairs and reconstruction based on the potential of organizational-technological solutions and analyzes the response surfaces, that is, the values of the integral potential depending on expert assessments of input factors.

TENDENCIES OF RECONSTRUCTION OF OLD INDUSTRIAL BUILDINGS AND TERRITORIES FOR THE PURPOSE OF REPROFILING

Abstract
Currently, there is an urgent issue of developing recommendations in the field of reconstruction and redevelopment 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.

THE USE OF COMPOSITE MATERIALS IN RECONSTRUCTION OF FLOORS OF INDUSTRIAL BUILDINGS

Abstract
The article discusses the relevance of the use of composite materials in the reconstruction of exposed to heavy loads of concrete and reinforced concrete floors of industrial buildings. It is noted that at the present stage of development of the construction industry special attention is paid to the use of steel fibreconcrete, as this material allows with minimal material and labor costs to carry out work on the reconstruction of industrial floors. The novelty of this study is the use as an adhesive between the existing floor, which is to be restored and strengthened, and the newly laid steel-fiber concrete layer of polymer-bitumen composite material with the addition of cement and graphite powder, previously obtained by the authors experimentally. This material with the required thickness is also a structural layer for leveling the surface of the lower layer, reducing friction under the sole of the upper steel-fiber concrete layer and the existing floor. The paper presents the technology of work in the reconstruction. The composition of the steel-fiber concrete layer is adopted on the basis of studies by other authors. Despite the fact that the experiments proved the solidity and strength of the reconstruction of the floor by the developed technology, the article notes that the final characteristics of the proposed floor design and technology can be identified only during operation, which can be the basis for further research on optimizing the thickness of the layers proposed for use of composite materials. For the evaluation of economic efficiency of application of these composite materials in the reconstruction of the concrete floors in the course of the experiment, there are revealed some figures for labor and material costs.

ENVIRONMENTAL MONITORING OF ECOLOGICAL SAFETY IN AREAS OF CONSTRUCTION, RECONSTRUCTION AND OPERATION OF OBJECTS

https://doi.org/10.34031/2618-7183-2019-2-3-78-84
 78-84 p.
Abstract
Environmental monitoring of construction production should use modern scientific and technical method of physical, chemical and biological control for periodic or continuous monitoring and measurement of factors associated with chemical pollutants and physical and biological pollution on the spot, and for the correct assessment of environmental quality.
For a construction project, all stages of construction production need environmental monitoring due to different monitoring purposes.
During the entire construction period, environmental monitoring can accurately, timely, comprehensively reflect the impact of construction work on the site and the environment and provide a scientific basis for environmental management. Continuous monitoring provides real-time, up-to-date results to help environmental management professionals understand environmental quality in a site and be able to respond in a timely manner.
