The article presents an assessment of the environmental costs of dust pollution in local construction. The environmental assessment of construction in the region should take into account the optimal conditions for preventing damage to all related areas of activity, both during construction and throughout the life cycle of the project. Under the damage caused to the environment by dust emissions from construction and other sources, we mean additional costs necessary to eliminate the consequences of atmospheric pollution. Losses in the cost and productivity of finished construction products are increasing very significantly due to the introduction of measures to protect the environment from dust emissions. These losses are especially noticeable in the production of earthwork, installation, and plastering works. The purpose of the study is to determine the cost of damage caused by dust pollution, develop and propose solutions to reduce this type of damage and associated environmental costs.

The article presents an analysis of the impact of fine dust particles on the health of builders, released during the production of construction processes and suggests measures to reduce it. A serious threat to the health of workers on the construction site and people living in the vicinity of it is represented by fine dust particles in a suspended state, both in themselves and in the total concentration of harmful air pollution near construction production. Analysis of the monitoring of suspended matter concentrations has shown that the ratio between the time of exposure to suspended dust particles in different concentrations directly affects the health of people. Air pollution in the work area negatively affects performance, causes diseases in workers, and can cause injuries due to reduced visibility. The organization of conditions corresponding to labor protection and safety, healthy environmental conditions on the construction site will ensure an increase in labor productivity by up to 12% and improve the quality of processes performed.

This article discusses the calculations of the feasibility study for the expansion of housing construction in the city of Taganrog. The choice and justification of the number of storeys, design scheme, space-planning solutions for new construction for the development of design solutions is based on natural and climatic, urban planning, social and economic factors that are specific to each specific territory. To implement effective design solutions in housing construction, it is necessary to consider options for both new construction and reconstruction of the existing housing stock of the city. Technical and economic calculations for the reconstruction of existing residential buildings include determining the effectiveness of the demolition of old existing buildings, construction of new facilities of various functions in the liberated territories, modernization of existing residential buildings and other measures to improve the quality of life of the population living in a particular city. Effective design solutions for the development of housing construction in Taganrog require an economic assessment of possible options, which must be worked out in the pre-project documents, such as a feasibility study of the construction of objects.

This article discusses the calculations of the feasibility study for the expansion of housing construction in Rostov-on-don. The main part of Rostov-on - don, where the vast majority of buildings are concentrated - the city center, residential areas, main production areas, special purpose facilities-are located on the high right Bank of the don. Active formation of new multifunctional planning areas of the city: North, West, North-East. Leventsovsky and Suvorovsky districts are under construction. For implementation of design decisions on development of housing construction in Rostov-on-don there is a need of an economic assessment of possible options that it is necessary to study in pre-project documents, such as the feasibility study of construction of objects.

The article describes the methods of forming the program of technical and economic feasibility of reconstruction. The program is based on the technical and economic calculations which justify the need for its development. It is important to take into account the technical and economic indices which provide a minimal amount of construction works. During the development of technical and economic parameters, it is necessary to take into account the organization of construction, the terms of energy saving, heating, water supply, drainage and industrial waste water, human resources, the environment, the effectiveness of capital investments. All questions are considered for the perspective of the development of science and technology.
