Abstract
The article explores a possible way to reduce the burden on the environment, access to social and economic benefits during the demolition of dilapidated old buildings which have brick walls. The experience of making these works for the city of Dnepropetrovsk has been research, the shortcomings of the technology used have been analyzed. It is proposed to dismantle the brickwork in order to obtain a whole brick for the secondary use. The process of disassembling brick walls of dilapidated buildings was divided into technological processes - sorting fragments of masonry with the selection of organic inclusions and obtaining of unbeaten brick. Each of the technological processes was divided into manufacturing operations. The duration of their performance was determined by timing. Based on statistical observations of the processes and the proper mathematical calculation of the data the substantiated labor expenses and costs for production as well as 1000 bricks have been found. The cost of the obtained brick was determined according to the existing level of wages and the cost of operating hand electrical tools.
