LLC "InterRegionConstruction" (IRC LLC) started a set of preparatory works for rock drilling and blasting. It should be reminded that the Leningrad Region is a region with abundant presence of rocky soils, many of which are not subject to manual mechanical destruction. The rock outcrop at the construction site amounted to more than 800 cubic meters. Access roads have been organized, storage sites for material shelter have been provided, and wells are being drilled for further laying and installation of the explosive network.
