The article provides an analysis of engineering and geological surveys at the construction site. The study area is assigned to the fifth engineering-geological area of the first order (the area of large river valleys, composed of alluvial Upper Quaternary deposits). The geological structure of the site has been studied to a depth of 24.0 m. The following stratigraphic-genetic complexes are present in the study area: technogenic soils, Quaternary eluvial-deluvial deposits, Quaternary alluvial deposits and Neogene deposits. At the construction site, passed wells encountered one aquifer. Water-containing soils are soft-plastic loams, for which the semi-hard clays of the Tavolzhanskaya suite of the Neogene serve as a relative aquiclude. Of the unfavorable engineering and geological processes, it should be noted the potential flooding by groundwater, frosty heaving of soils and the ability of EGE 2 soils, in case of soaking under the influence of an external load, to show subsidence properties. Based on the data of the study of engineering and geological conditions of the site, the category of their complexity is II-difficult.

Key words: engineering-geological surveys, construction site, stratigraphic-genetic complexes, aquifer
