Abstract. The results of studies on the concentration of fine dust concentrations during construction work are presented. A method developed by the authors for modeling the dynamics of air flow and the zone of distribution of impurities, taking into account external non-stationary factors during construction work on the basis of a specialized GIS application, is considered. It is proposed to use in contaminated areas after construction and repair and emergency work of a dust collector, which is aimed at reducing pollution. The main element of the dust-harvesting machine is designed for cleaning hard surfaces, namely from debris, sand and gravel masses, dust particles, estimates and liquid waste. The use of solar collectors in the dust collecting unit allows the dust collecting machine to have a long operating mode, it does not require additional energy resources when the machine is running.

Key words: Fine dust, GIS application, dust removal machine, construction work.
