The paper explores the use ofpolycarbonate modular systems in the construction of translucent building envelopsfor sports facilities. Basedonthecomparisonofthelighttransmissionperformance involving the most widely used translucent materials, it is easy to see that they are inferior to nearly all other materials. Certain characteristics of cellular polycarbonate sheets are summarized intabularform depending on the number of layers and the cellular structure. Further emphasis is made on the fact the existing lock connections for assembly of large-scale planar structures are not always consistent with the constructability and occupational safety requirements.

The problem of parking of cars on the street-road network of the city of Volgograd is considered. The methods of parking at different angles in the winter season have been studied, and the most optimal one has been selected and justified. Dense building does not allow to solve this problem by searching for other parking places, since each driver has a desire to be within walking distance of the car to the object he needs. In residential areas of the city with the existing buildings, this problem is difficult to solve, therefore, it is necessary to improve the existing schemes for parking in the instrument areas
